nana's Issues

Build fails on Linux

Hi,
When I built nana on Linux, there was an error on source/detail/linux_X11/platform_spec.cpp.

nana::screen::for_each multiple monitor enumeration throws exception

I have tested multiple display monitor support feature (nana/gui/screen.hpp) in ver 1.0.1 .
And met the issue.

Currently, nana::screen implementation uses these Windows APIs.

EnumDisplayDevices
EnumDisplaySettings

In my testing environment, return value of screen::count method (which uses EnumDisplayDevices to check the number of monitors) is more than the number of attached monitors.

It seems like EnumDisplayDevices enumerate adapters instead of monitors.
and in nana::real_display constructor, EnumDisplaySettings API returned 0(failed).

I could get the number of phyisical moniors with another APIs.
Below are the sample code.

#include <nana/gui/screen.hpp>
#include <Windows.h>

using namespace nana;

BOOL __stdcall MyInfoEnumProc(HMONITOR hMon, HDC hDC, LPRECT rect, LPARAM lParam)
{
    MONITORINFOEX mi;
    mi.cbSize = sizeof(MONITORINFOEX);
    if (GetMonitorInfo(hMon, &mi)) {
        int hoge = 0;
    }
    return TRUE;
}

int main()
{
    EnumDisplayMonitors(NULL, NULL, MyInfoEnumProc, 0);
    int num = GetSystemMetrics(SM_CMONITORS);

#if 0
    using namespace nana;
    auto s = screen();
    int count = s.count();
    int test = 0;
    s.for_each([&](display& d){
        int hoge = 0;
    });
#endif

}

Quote from http://stackoverflow.com/questions/18022612/enumerating-monitors-on-a-computer/18263412#18263412

Then, there is a difference between display adapters and monitors. EnumDisplayDevices shows you adapters and EnumDisplayMonitors shows you the monitors. The former is primarily to just enumerate the adapters but the latter allows you to provide a clipping rectangle and determine which monitors that clipping rectangle happens to land on. This becomes useful when you have multiple active monitors and someone decides to do something that causes a draw that will straddle multiple monitors. You get to specify a callback to EnumDisplayMonitors and that callback will be invoked with some parameters (if memory serves me correctly one of the parameters was a subset of the specified clipping rectangle that lands on the specified monitor).

why i can not find ft2builder but libfreetype2 and libfreetype2-dev are installed and their links are exists in /usr/include/freetype2/ft2build.h

Closing menu does not restore focus of a widget

Below is the code and steps to reproduce the issue.

#include <nana/gui.hpp>
#include <nana/gui/widgets/menubar.hpp>
#include <nana/gui/widgets/textbox.hpp>

using namespace nana;

int main()
{
    using namespace nana;
    form fm(API::make_center(400, 500));
    menubar mb;
    mb.create(fm);
    mb.push_back(L"&aaaaaa");
    mb.push_back(L"&baaaaa");
    mb.at(0).append(L"&1", [](menu::item_proxy& ip){

    });
    mb.at(0).append(L"&2", [](menu::item_proxy& ip){

    });
    mb.at(1).append(L"&1", [](menu::item_proxy& ip){

    });
    mb.at(1).append(L"&2", [](menu::item_proxy& ip){

    });

    textbox txt(fm, rectangle(10, 60, 200, 30));

    fm.show();
    exec();
}

Click and set focus to the textbox.
Click the menubar to open the menu.
Click a menuitem.
Focus of the textbox widget is lost.

Don't typedef 'nana::string' as an alias for `std::wstring` on Linux systems

More info here. In short: std::wstring sucks on Linux systems. Badly.

Missing file test.cpp

I want to use Nana as a git submodule for a project.

My project structure is as follows

source/ -> project source files
external/ -> git submodules, nana is located here
CMakeLists.txt

After attempting an out of source build with cmake, I get the following error

CMake Error at external/nana/CMakeLists.txt:146 (add_executable):
Cannot find source file:
test.cpp

which seems to be caused by the cmake line

graphics::save_as_file() method should follow bitmap 4 byte alignment format.

Line size of RGB bitmap must be 4 byte aligned and internally it is so.
The problem appears when graphics width is not multiple of 4.
I modified the code to resolve the problem.

        void graphics::save_as_file(const char* file) const
        {
            if(handle_)
            {
#if defined(NANA_WINDOWS)
                int iWidth = static_cast<int>(size_.width);
                int iHeight = static_cast<int>(size_.height);
                BITMAPINFO bmpInfo = {};
                bmpInfo.bmiHeader.biSize = sizeof(bmpInfo.bmiHeader);
                bmpInfo.bmiHeader.biWidth = static_cast<int>(size_.width);
                bmpInfo.bmiHeader.biHeight = static_cast<int>(size_.height);
                bmpInfo.bmiHeader.biPlanes = 1;
                bmpInfo.bmiHeader.biBitCount = 24;

                const size_t lineBytes = ((bmpInfo.bmiHeader.biWidth * 3) + 3) & (~3);
                const size_t imageBytes = iHeight * lineBytes;

                HDC hdcMem = ::CreateCompatibleDC(handle_->context);
                BYTE *pData = nullptr;
                HBITMAP hBmp = CreateDIBSection(hdcMem, &bmpInfo, DIB_RGB_COLORS, reinterpret_cast<void**>(&pData), 0, 0);

                ::SelectObject(hdcMem, hBmp);

                BitBlt(hdcMem, 0, 0, iWidth, iHeight, handle_->context, 0, 0, SRCCOPY);

                BITMAPFILEHEADER bmFileHeader = {0};
                bmFileHeader.bfType = 0x4d42;  //bmp
                bmFileHeader.bfOffBits = sizeof(BITMAPFILEHEADER) + sizeof(BITMAPINFOHEADER);
                bmFileHeader.bfSize = bmFileHeader.bfOffBits + imageBytes;

                HANDLE hFile = CreateFileA(file, GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
                DWORD dwWrite = 0;
                WriteFile(hFile, &bmFileHeader, sizeof(BITMAPFILEHEADER), &dwWrite, NULL);
                WriteFile(hFile, &bmpInfo.bmiHeader, sizeof(BITMAPINFOHEADER), &dwWrite, NULL);
                WriteFile(hFile, pData, imageBytes, &dwWrite, NULL);
                CloseHandle(hFile);

                ::DeleteObject(hBmp);
                ::DeleteDC(hdcMem);

debugging - throw_not_utf8 and place

Hi !
I'm adapting my app from v1.1 to v1.3
I know I have problems with non ASCII characters that I need to make utf8 now.
But anyway, I'm using the "opportunity" to improve the error handling of my app.
I'm catching exceptions and adding nice messages.

It is more difficult that I wanted.
Here are some of my problems:

some widgets will throw if some text is not utf8. It may be OK, but it may be situations in which we don't have full control of the text (may come from a file, WWW etc) and one may want to force printing the text, even if it will have some crap... at least to debug! For example: introduce some state flag that tell nana not to throw_not_utf8, but print a cerr error and continue with the crappy text. (it will change only the code of throw_not_utf8)
a related problem: the msgboxwill refuse and will throw! if you try to report that text. msgboxis therefore a good candidate to force (using some explicit arg ) non utf8, crappy print.
this is a huge problem if you try to show a msgbox in the catchof an exception - which is very natural - and it terminate the program and you don't have any idea why.
difficults come from the fact than before drawing and redrawing was basically a safe function, but now may not because of throw_not_utf8.
going to a catch, c++ will destroy c++ objects, making nana destroy some widgets from inside of some destructor. It can call collocate, which can throw. You prevent this with this code, but somehow is_destroying is not always working, and it is difficult to debug why. When it throw here the program is killed.

        //Listen to destroy of a window
        //It will delete the element and recollocate when the window destroyed.
        event_handle _m_make_destroy(window wd)
        {
            return API::events(wd).destroy.connect([this, wd](const arg_destroy&)
            {
                for (auto i = elements.begin(), end = elements.end(); i != end; ++i)
                {
                    if (!API::is_destroying(API::get_parent_window(wd)))
                        place_ptr_->collocate();
                }
            });
        }

BDW - I don't understand what is with the iteratori that is not used, maybe you wanted i->collocate();? ...

list copy/paste and sort

Hi,
I'm using the list model.
It was simple to set, and is working very fast (tested 50 000 items) but I have two problems: (sorry is long, but trivial)

the ctrl-a, ctrl+c for copy crash because it call item_data::to_string() which have no idea of the model and have an empty cells which throw out of index.
I don't understand how to set a comp function that need access to the targets_comp object.

So... it maybe crazy (we have to many different possibilities!) but maybe we can set four more members (std::funtions) on the header object : to_string(), to_cell, set_value() and comp() each taking a reference to the model object (CProgParam_SondeDesign::targets_comp& - in my case)? It will be very easy to setup, more consistent ....

        list.append_header(   "T Pos",        60);
        list.append_header(   "T Cand",       60);

        list.append_header(   "N Pos",        60);
        list.append_header(   "N Cand",       60);
        list.append_header(   "Targ #",       50);
        list.append_header(   "Targ name",        100);
        list.append_header(   "N Cand",       60);
        list.append_header(   "N Pos",        60);

        list.append_header(   "Num T Hits",       80);
        list.append_header(   "Num Hits OK",      80);

        list.append_header(   "N Pos",        60);

Listbox enable_single crash

Inside the method:

void trigger::mouse_down(graph_reference, const arg_mouse& arg) { ... }

It is essential to check for the item pointer or the application will crash when selecting a category:
if (!lister.single_selection()){ ... } else { if (item_ptr) { sel = !item_proxy(essence_, index_pair(item_pos.cat, lister.absolute(item_pos))).selected(); } }
if the listbox was created with enable_single.

the click event lost mouse and keyboard info

I don't think changing the click event from basic_event<arg_mouse> to basic_event<arg_click> is a good idea. It causes losing many useful infomations and making the click and dbl_click acting quite differently.
Perhap inheriting arg_click from arg_mouse is more suitable.

ps:why the Alt key disappeared from nana?

    struct arg_mouse
        : public event_arg
    {
        event_code evt_code; ///< 
        ::nana::window window_handle;  ///< A handle to the event window
        ::nana::point pos;   ///< cursor position in the event window
        ::nana::mouse button;   ///< indicates a button which triggers the event

        bool left_button;    ///< mouse left button is pressed?
        bool mid_button;     ///< mouse middle button is pressed?
        bool right_button;   ///< mouse right button is pressed?
        bool shift;          ///< keyboard Shift is pressed?
        bool ctrl;           ///< keyboard Ctrl is pressed?
    };

    struct arg_click : public event_arg
    {
        ::nana::window window_handle;   ///< A handle to the event window
        bool by_mouse;                  ///< Determines whether the event is emitted by clicking mouse button
    };

    basic_event<arg_click> click;       ///< the window is clicked, but occurs after mouse_down and            before mouse_up
    basic_event<arg_mouse> dbl_click;   ///< the window is double clicked

examples compiled with develop branch

Hi,
congratulation, I compiled all the 50 examples with VS2015 in Windows 7 Pro 64x using debug Win32 and static linked cpp run time:
(I returned some configuration to the project)

fix leak of memory for class animation

and with 0 errors and 0 warnings.

Now I will run each and test and will write here the results.

API::eat_tabstop(widget, false) does not work well when there is only one widget (textbox) in a form.

With API::eat_tabstop(widget, false), I can change the focus of widgets by pressing tab key.

Here is working example code.

#include <nana/gui.hpp>
#include <nana/gui/widgets/textbox.hpp>

using namespace nana;

int main()
{
    using namespace nana;

    form fm(API::make_center(500, 300));
    fm.caption(L"tabstop test");

    textbox txt(fm, rectangle{50, 50, 100, 30});
    txt.multi_lines(false);
    txt.caption(L"aaaa");

    textbox txt2(fm, rectangle(50, 90, 200, 200));
    txt2.caption(L"aaaa\nbbbb\ncccc\n");

    API::eat_tabstop(txt, false);
    API::eat_tabstop(txt2, false);

    fm.show();
    exec();
}

But when there's only one textbox widget in a form, pressing tab key shows different result.

Please test below code.

#include <nana/gui.hpp>
#include <nana/gui/widgets/textbox.hpp>

using namespace nana;

int main()
{
    using namespace nana;

    form fm(API::make_center(500, 300));
    fm.caption(L"tabstop test");

    textbox txt(fm, rectangle{50, 50, 100, 30});
    txt.multi_lines(false);
    txt.caption(L"aaaa");

    API::eat_tabstop(txt, false);

    fm.show();
    exec();
}

With above code, the textbox widget eats the tab and put it into its text editor, but that is different from expected behavior.

Consider using a tool such as Bakefile

Currently, all the build files are hand-written. This is prone to error and maintenance hell as time passes. You should consider using Bakefile, which is based on the idea of pre-generating the build files. You run Bakefile on your computer, upload the generated files, and the user doesn't even know it exists.

It supports VS 2013 and GNU make. I can look into opening a PR for Code Blocks if desired.

Also, I'd be happy to contribute the build files if it's decided that this would be a good idea.

Form widget does not respond to Alt + F4 key.

Other Windows applications as I know of so far handle Alt + F4 key.
So I thought It would be fine if nana library could handle the key down as a user's operation to close the form. And... sorry, I don't remeber if applications on X Window behaves the same.

CMake policy warning: policy not set

I am again trying to use Nana as a submodule for a project and encountered the following warning when generating the project with CMake.

I am using CMake 3.2.0 on Windows 7 and using the "develop" branch

CMake Warning (dev) at external/nana/CMakeLists.txt:8 (if):
Policy CMP0054 is not set: Only interpret if() arguments as variables or
keywords when unquoted. Run "cmake --help-policy CMP0054" for policy
details. Use the cmake_policy command to set the policy and suppress this
warning.

Quoted variables like "MSVC" will no longer be dereferenced when the policy
is set to NEW. Since the policy is not set the OLD behavior will be used.
This warning is for project developers. Use -Wno-dev to suppress it.

Is it possible to set this policy as it adds to the overall noise of warnings which might actually break something someday

Hidden widgets (textbox, etc) still show carets & pressing tab key switches focus on invisible(hidden) widgets.

I think hidden widgets should not retain focus. If it has a focus, its focus should be lost.

Doesn't build with clang/libc++

The program wont build using libc++ and clang on linux. I have problems with using libstdc++ on linux because of missing functions and errors when compiling it with clang.

remove include/nana/config.hpp from git?

Is include/nana/config.hpp computer generated? If so it should be removed from git repo and added to the gitignore. My machine generates a different one after the build and shows up in git status as modified.

On a related note, is there a reason why fixes are not merged into master right away? I understand new features may go into a development branch first but I don't understand why fixes for the master are not on the master right away. If a new user downloads the repo and tries to build he could run into the same problem again unless he knows to check out the hotfix branch instead, which is unlikely. If you want to have versioned releases I suppose you can always create named tags for the corresponding commits.

listbox incorrectly renderes reordered last column

Initial screen after the startup of program.

Top row selected.

Last column reoreded to left-most, still correct.

Column widths shrinked by dragging header borders. still looking alright.

(sometimes column reorederd unexpectedly after dragend timing if I dragged the column border excessively but that is another matter...)

Bottom row selected.

Please pay attension to the bottom row since middle and last columns rendered improperly.

The problem disappears after I expanded ex-last-column.

Uninitialized slider widget behaves unexpectedly.

I thought slider's knob stays on the position when I clicked it. But it stopped on a different position (left side). After some testing, I noticed uninitialized slider doesn't behave as I thought. If I called vmax & value methods of slider widget, It behaves normally.

I still haven't looked up into the source code of the widget to figure out the cause. Probablly it would be of no harm to initialize some member variables in a constructor.

Additionally, this is a subtle thing but slider's knob moves one pixel left after I clicked a slider.

Please run below sample code and click various positions of sl3 slider and make sure if the problem reproduces at your side.


#include <nana/gui.hpp>
#include <nana/gui/widgets/slider.hpp>

int main()
{
    using namespace nana;
    form fm(API::make_center(500, 500));

    slider sl1(fm, rectangle(10, 10, 300, 10));
    slider sl2(fm, rectangle(10, 50, 300, 10));
    slider sl3(fm, rectangle(10, 90, 300, 10));

    sl1.vmax(1000);
    sl1.value(100);

    sl2.vmax(2000);
    sl2.value(2000);

    //drawing{ fm }.draw([](paint::graphics& graph){
    //  graph.string({ 10, 10 }, L"Hello, world!", colors::red);
    //});
    //fm.events().click(API::exit);
    fm.show();

    exec();
}

key_press/krey_release events

Hi,

I am using form.events().key_press[release]() to subscribe to keyboard events. Unfortunately when I press any key and hold it down I get lots and lots of key_press/key_release calls - simply as OS is repeating key. This is not behavior I want and would expect - I need one press and one release.

Is this known issue? Or maybe this is by design? Can I change the behavior?

.gitignore

Hi !
There is a *.suo file in the repository. We need it? If this is just an small error it can be included in .gitignore. Anyway it can be good to have an .gitignore. There are many examples in:
https://github.com/github/gitignore
and this is what I use:
https://github.com/qPCR4vir/myNana/blob/master/.gitignore
Also, you recommend to build the static lib in:
NanaPath/build/bin/IDEName
I think this dir and any other temporal dir for compiler/link need to be in .ignore too... etc. Only the original code have to be under source control, to help "pushing" and "pulling"

nana displays below message with MessageBoxA.

---------------------------
Nana C++ Library
---------------------------
Nana.GUI detects a memory leaks in events operation, 1 event(s) are not uninstalled.

OK   
---------------------------

Below are the code to reproduce.

#include <nana/gui.hpp>

int main()
{
    using namespace nana;

    form fm(API::make_center(300, 300));
    fm.events().click([&](const arg_mouse& arg){
        msgbox mb(fm, L"test", msgbox::ok);
        mb.icon(mb.icon_question);
        mb << L"Test";
        mb.show();
    });

#if 0
    fm.show();
    exec();
#else
    fm.modality();
#endif
}

Typically top level root window doesn't need to be shown with modality method, but I switched non-top-level window to be top-level-window for testing purpose (I wanted to skip tedious operations to open child form during testing).

And I wish the messages will be displayed in output window. The error message is displayed on MessageBox in debug & release build but that makes end-user be causcious of the inner problem.

Caret of textbox in a panel does not move correctly when the panel (and its children widgets) is moved.

Please use below code to reproduce the issue.

#include <nana/gui.hpp>
#include <nana/gui/widgets/panel.hpp>
#include <nana/gui/widgets/textbox.hpp>

using namespace nana;

int main()
{
    using namespace nana;

    form fm(API::make_center(500, 300));
    fm.caption(L"tabstop test");

    panel<true> panel(fm, rectangle(fm.size()));

    textbox txt(panel, rectangle{50, 50, 100, 30});
    txt.multi_lines(false);
    txt.caption(L"aaaa");

    API::eat_tabstop(txt, false);

    fm.events().resized([&] (const arg_resized& arg) {
        auto size = panel.size();
        panel.move(arg.width - size.width, arg.height - size.height);
    });

    txt.focus();

    fm.show();
    exec();
}

After the form is shown, resize the dialog and see position of textbox's caret.

combox back but not del

Hi,
Editing in combox back key erase a char but del dont work

Inverted vertical slider

When a vertical slider is used, it seems to be inverted (0 at the top and vmax at the bottom).

I suppose it's a bug. I looked at the code but I didn't find a way to fix this.

Thanks to look at this

Nana install misses include files

Using CMake, gcc 5.3 and Fedora 23 64-bit:
After setting CMAKE_INSTALL_PREFIX to specify the installation directory, the build succeeds but the installation directory contains only libnana.a. The install directory should also contain the required include files.

Tag nana_v1.0

Hi !
It could be good to add a simple git tag in this first commit.
(learning GitHub)

Insanely weird behavior of text boxes on Linux

This is hard to explain. I open up the Notepad demo app. If I cycle between a, s, and d, the text cursor will start jumping down and up and left and right and inserting newlines. Pressing the space tends to move up a line.

In the place_login demo app, doing the same thing looks fine. However:

If I select all the text and start typing, it will be prepended to the beginning instead of replacing the selected text.
If I prepend text to the beginning and cycle through a, s, and d again, the text cursor will gradually move to the right.

Also, API::exit doesn't seem to exit anything. The window just stays there.

I love Nana, but this is just insane.

Wrong source file discovery in CMakeLists

The CMakeLists.txt file uses the following lines to collect all relevant source files

set(NANA_SOURCE_DIR ${CMAKE_SOURCE_DIR}/source)
set(NANA_INCLUDE_DIR ${CMAKE_SOURCE_DIR}/include)

Which causes major problems when using Nana as a sub project in cmake.
The lines should be changed to

set(NANA_SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/source)
set(NANA_INCLUDE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/include)

textbox: Linux/X11+Unicode strange caracters on shift, ctrl, arrows, etc

When using the textbox on Linux, nana inserts squares in the text when pressing arrow keys, shift, ctrl, capslock, insert, home, etc...
Shift also causes some other issues, as entering shift+1 ( !, the exclamation) twice erases a portion of the text, as if the text got selected then replaced.

Runtime-Error with Menus and modal Dialogs

Hi Jinhao,

i'm facing an error with Menus and opening a modal Dialog.
A stripped down sample as the following shows the error:

#include <nana/gui.hpp>
#include <nana/gui/place.hpp>
#include <nana/gui/widgets/menubar.hpp>

int main(int argc, char **argv)
{
    nana::form fm;
    nana::place pl(fm);
    nana::menubar mn(fm);

    pl.div("<vertical <menu weight=25>>");
    pl.field("menu") << mn; 

    mn.push_back(L"test");
    mn.at(0).append(L"open modal window", [&fm](nana::menu::item_proxy& ip)
    {
        nana::form fm2(fm);
        fm2.show();
        fm2.modality();
    });

    pl.collocate();

    fm.show();

    nana::exec();

    return 0;
}

After opening fm2 via the Menu and closing the Form, the error occurs.

last callstack entry is:
0 0x00000000005781b6 std::unique_ptr<nana::basic_event<nana::arg_mouse>::docker, std::default_delete<nana::basic_event<nana::arg_mouse>::docker> >::~unique_ptr

if i understand correctly, the error occurs in the destructor of an unique_ptr.

The system i'm using is nana with the latest master branch, windows 8.1 with mingw (gcc 4.9.2).

If you need further information please let me know.

best regards, jan
^

additional note:
if you open a window via a button or something else, no error occurs. this makes me guess the error is relating to menubars

Pressing ALT + SPACE key does not show shortcut menu.

When I press Alt + Space key with typical Windows application,
it displays active window's system menu.

Please search "ALT+SPACE" in below page.
https://msdn.microsoft.com/en-us/library/ms971323.aspx

I confirmed that putting another

                def_window_proc = true;

before the break of case WM_SYSCHAR: in nana::detail::Bedrock_WIN32_WindowProc function can solve the issue.

cmake thread default for MinGW out of date

NANA_THREAD_NOT_SUPPORTED is hard coded in CMakeLists.txt to ON. I think it should be OFF by default esp. for non-gui users of cmake. Better yet this could be automatically tested. I followed the example given in this SO post and wrote a test for this:

option(NANA_THREAD_NOT_SUPPORTED "Use this flag if MinGW version is older than 4.8.1" OFF)
if(CMAKE_CXX_COMPILER_ID STREQUAL "GNU")
  if(CMAKE_CXX_COMPILER_VERSION VERSION_LESS "4.8.1")
    option(NANA_THREAD_NOT_SUPPORTED "Use this flag if MinGW version is older than 4.8.1" ON)
  endif()
endif()

Compilatation error on vs2015

When compiling the development branch using the project in build\vc2015 and VS2015 Enterprise, the compiler gives the following error:

c:\users\waty\source\repos\nana\source\gui\element.cpp(267): error C2662: 'nana::rectangle &nana::rectangle::pare_off(int)': cannot convert 'this' pointer from 'const nana::rectangle' to 'nana::rectangle &'

The error disapears when you change

graph.rectangle(::nana::rectangle{ r }.pare_off(1), false, bgcolor);

graph.rectangle(::nana::rectangle(r).pare_off(1), false, bgcolor);

high ram usage

Hi,

when i run this simple program:

#include <nana/gui.hpp>
int main()
{
    nana::form f;
    f.show();
    nana::exec();
    return 0;
}

it starts windowed and takes 2MB of ram, very much for a simple form.
When i maximize the form, it suddenly takes up to 18MB of ram.

If I add widgets, it suddenly uses even more than that, and i mean not just some more bytes, but again Megabytes more.

This happens in Debug and Release mode, and is independent from the used compiler (tried vc2015 and mingw 5.1) at least on Windows 10. I'm not able to test on other platforms currently.

in my opinion the ram usage is way to high.

is this known and accepted or is somebody working on it?

can we do something to get the ram usage lower?

best regards, jan

Pressing mouse button outside of widget area pushes the button widget.

Hi, I noticed pressing mouse button outside of widget area pushes the button widget.
Below are the steps to reproduce it.

Press a button widget with mouse click and do not release it. A bit strangely, it reacts to any (left/middle/right) mouse button.
Keep pressing mouse button and move mouse cursor to outside of the button widget.
Press another mouse button while pressing the first mouse button.
The button widget is pushed while mouse button is pressed. Luckily, click event is not fired.

Issues about config.hpp

Hi, guys
@ierofant , @roberthauck , @qPCR4vir please update the cmake file for config.hpp if you have spare time. Thank you.

The config.hpp has been separated into two parts. (develop branch)

Some symbols, such as adaption of target OS, workarounds compiler errors and lack of std C++ supports, are defined in c++defines.hpp. This part should not be modified by developer, these symbols is detected automatically.

Some symbols for external libraries are defined in config.hpp. Developers can modify the symbols defined in config.hpp to enable/disable features.

BTW, another question. What versions of libstdc++ and libc++ support std::make_unique? I only know GCC 4.9 supports std::make_unique, but I have now idea what version of libstdc++ is.

bug: menu and tooltip in some corner in secound display.

Hi,
When I attach a second display to my laptop and make it the principal display all work OK.
But if the attached display is secondary when my nana program is there, the tooltip and menus open in different wrong place.
Other programs run OK.
I was thinking this is a new problem, but not. All my old executable have the same problems, just that I always used the attached display as principal.
I use Windows 7 pro x64

Compile error with API::enum_widgets

Compile error appears when I try to build a program that uses API::enum_widgets.

Usage is like this.

API::enum_widgets(fm, false, [&](::nana::widget& widget){
    if (widget.handle() == mb.handle()) {
        return;
    }
    if (bShowPreview) {
        widget.hide();
    }else {
        widget.show();
    }
});

It seems the cause is with this commit, Revision: 1b5aed2
File : include/nana/gui/programming_interface.hpp
In nana::detail::enum_widgets_function::_m_enum_fn(), new implementation supplies two argments to _m_enum_call method.
After removing 2nd argment nullptr, the compile error is no more.

nana/include/nana/gui/programming_interface.hpp

Line 116 in 1b5aed2

return _m_enum_call<Widget>(wd, nullptr);

Move environment detection to cpp files

In CMakeLists.txt, we detect environment and copy them into config.hpp.

In fact, we can use some compiler detection libraries(such as boost/predef) to do this job. We can easily detect compiler versions in cpp files.

eg.

#if defined(__MINGW__) && __GNUC_MINOR__ < 8
#define   NANA_THREAD_NOT_SUPPORTED
#endif

Submenu in a menu bar does not work.

Hi, I'd like to use submenus in a menu bar but so far I can't make it work.
I use below code to check the issue. Could you please take a look at it?

#include <nana/gui.hpp>
#include <nana/gui/widgets/menubar.hpp>

int main()
{
    using namespace nana;

    form fm(API::make_center(500, 300));
    fm.caption(L"submenu test");

    menubar mb(fm);
    mb.push_back(L"&File");
    mb.push_back(L"&View");

    auto& menu_view = mb.at(1);
    menu_view.append(L"Test 0");
    menu_view.append(L"Test 1");
    menu_view.create_sub_menu(1)->append(L"aa");

    // from http://nanapro.org/en-us/help/widgets/menu.htm
    menu mobj;
    mobj.append(STR("Item 0"));
    mobj.append(STR("Item 1"));
        mobj.create_sub_menu(1)->append(STR("A sub menu item"));
    mobj.renderer(mobj.renderer());
    mobj.item_pixels(30);

    fm.events().click(menu_popuper(mobj));

    fm.show();
    exec();
}
