tkd's Issues

window.d needs import for tkd.image.image for setIcon

commandCallbackHandler catches Throwable making unrecoverable Errors impossible

In this code:

catch (Throwable ex)
{
	string error = "Error occurred in command callback. ";
	error ~= ex.msg ~ "\n";
	error ~= "Element: " ~ args.element.id ~ "\n";

	Tcl_SetResult(tclInterpreter, error.toStringz, TCL_STATIC);
	return TCL_ERROR;
}

Instead of catching Exception, it catches Throwable, making erroneous states that cannot logically be recovered from impossible. If the program throws an Error it will continue, even if this Error was caused by memory corruption or other such unrecoverable errata. It should instead catch Exception which is reserved for errors that are safe to catch and handle (and therefore continue or recover from.)

Add note for linker flags in windows needed to prevent console window.

From this thread : http://forum.dlang.org/post/[email protected]

"lflags":[-L/exet:nt/su:windows] is needed to be added to the dub.json to prevent the console window from appearing.

Test if adding a parent to a window alters behaviour

Test if adding a parent to a window alters behaviour especially regarding stacking. For example if a dialog box is raised does it always stay above the main window?

Minor bugs in example

Hello!
I decided to try tkd and noticed these things (compiled with ldc2 in linux). Cheers.

If you click file type filter or directory path button in a dialog clicking the button again won't close the popup and you have to click one of the texts to close it.

This one widget goes out of bounds to down/right when moved.

GDC fails

Building with GDC 4.9 on Arch x64 fails. The example segfaults of building in debug mode, and it gives OutOfMemory if built with release.

GUI Builder for Tk

Hello there,
I'm looking for a software allowing the creation of Tk GUI returning XML Or UI format. Should I use Gtk instead of Tk ? On Tcl/Tk I read it could be possible to perform it by using Glade, is it ?

Thank to community.

Menu Alt-Shortcut not working in example.

In the example application entering a menu shortcut, e.g. Alt-F issues an error.
The message is:

grab failed: window not viewable
grab failed: window not viewable
    while executing
"grab -global $w"
    (procedure "tk::TraverseToMenu" line 20)
    invoked from within
"tk::TraverseToMenu .frame-F4FBE983.labelframe-3920BD3D.text-49FBE756 f"
    (command bound to event)

Happens on ubuntu with dmd.

Karl

Rebinding default tk keys does not work

I posted this issue on dlang forum first but since nobody seems to have an answer I created an issue here.

I want to rebind <Control-a> to select all text in the Entry widget, it doesn't work

private void selectText(CommandArgs args) {
    this._clientId.selectText;
}

this._loginFrame = new Frame(2, ReliefStyle.groove);
this._clientId = new Entry(this._loginFrame).grid(1, 0);
this._clientId.bind("<Control-a>", &selectText);

It works if I change <Control-a> to <Control-o> for example.

Implement the geometry methods fully

does canvas use the gpu to draw?

does canvas use the gpu to draw?
if not can this be a added feature?

I would love to make a game and editor using the library and having to manager two graphics libraries are a pain.

text widget appendText escaping

auto editor = new Text();
editor.appendText("{");

outputs In text widget:

\{

Possible solution:
Use the following for the escaper:

string escape(string arg)
{
  string replacer(Captures!(string) m)
  {
    final switch(m.hit) 
    {
      case `\`: return `\\`;
      case `"`: return `\"`;
      case `$`: return `\$`;
      case `[`: return `\[`;
      case `]`: return `\]`;                
    }
    assert(false);
  }     
  return arg.replaceAll!(replacer)(regex(`\\|"|\$|\[|\]`));       
}

And insert the text using:

this._tk.eval(`%s insert end "%s"`, this.id, text);

Tab key produces a script error instead of tabbing to next widget

I get this error even if I add .setKeyboardFocus(KeyboardFocus.normal) to buttons

invalid command name "tk_focusNext"

package.json windows pregenerate

Looks these are wrong on your repo readme:

"postGenerateCommands-windows-x86": [
    "copy $TCLTK_PACKAGE_DIR\\dist\\x86\\tcl86.dll build\\tcl86.dll /y",
    "copy $TCLTK_PACKAGE_DIR\\dist\\x86\\tk86.dll build\\tk86.dll /y",
    "copy $TCLTK_PACKAGE_DIR\\dist\\x86\\zlib1.dll build\\zlib1.dll /y",
    "xcopy $TCLTK_PACKAGE_DIR\\dist\\library build\\library /i /e /y",
],
"postGenerateCommands-windows-x86_64": [
    "copy $TCLTK_PACKAGE_DIR\\dist\\x86_64\\tcl86.dll build\\tcl86.dll /y",
    "copy $TCLTK_PACKAGE_DIR\\dist\\x86_64\\tk86.dll build\\tk86.dll /y",
    "copy $TCLTK_PACKAGE_DIR\\dist\\x86_64\\zlib1.dll build\\zlib1.dll /y",
    "xcopy $TCLTK_PACKAGE_DIR\\dist\\library build\\library /i /e /y",
],

should be tcl86t.dll, tk86t.dll, and zlib is not present

How can I get currently selected tab in NoteBook widget?

Here is an example:

I need to know which tab is active whenever a user hits "Ok" button. Tk NoteBook widget should have select method which returns currently active tab but I could only find selectTab which just selects the tab. How can I know which tab is currently active?

Posix file dialogs show hidden files and directories

This is really a pain, as often these dialogs start at the home directory which is full of hidden files and directories in Linux.

There is a workaround for this unlucky default setup of file dialogs. Please see [(http://wiki.tcl.tk/1060)] when the discussion reaches June 2011: 'Is there a way to disable displaying of hidden directories in Linux (starting with a dot ".") when file sector dialog opens?'.

So I would like to put the following workaround for tkd into discussion. (I am new in D-programming, so there might well be a smarter approach.)

Background: As this workaround allocates resources (a dummy call to tk_getOpenFile is needed), it should be executed only once and only if the application uses DirectoryDialog, OpenFileDialog or SaveFileDialog.

Add following member to Dialog:

/**
 * Workaround to fix default of file dialogs showing unwanted
 * hidden files and directories on Posix systems.
 *
 * To be called from constructor of FileDialog and of DirectoryDialog
 * when on version(Posix).
 */
protected final void fixFileOrDirDialog() {
    static bool fixed;
    if (!fixed) {
        fixed = true;
        this._tk.eval("catch {tk_getOpenFile foo bar}");   // Dummy that instanciates below variables.
        this._tk.eval("set ::tk::dialog::file::showHiddenVar 0");  // Don't show hidden entities.
        this._tk.eval("set ::tk::dialog::file::showHiddenBtn 1");  // Show switch for hiddent entities.
    }
}

Modify the constructor of FileDialog (line 57ff) as follows:

this(Window parent, string title)
{
    this._typeVariable = format("variable-%s", this.generateHash("%s%s", this._elementId, this.id));
    super(parent, title);
    version(Posix) fixFileOrDirDialog();
}

Modify the constructor of DirectoryDialog (54ff) as follows:

this(Window parent, string title = "Directory")
{
    super(parent, title);
    version(Posix) fixFileOrDirDialog();
}

Sorry, but I could not find a solution where to touch only one spot in the code while holding the background condition mentioned above.

Karl

Delete rows from TreeView

It doesn't appear that there is any way to delete individual rows from a TreeView barring deleting them all with deleteRows(). Calling destroy() on TreeViewRow does nothing. I thought then maybe I could do it the incredibly inefficient way and get all rows, delete them all from the tree, build a new list of rows (checking manually as to not add ones I want to remove), then adding that new list back. The thing is, I can't even do that because there's no way to get the list of all rows! Is the functionality really that incomplete, or am I missing something here?

example crashes on osx

README package.json typos

You may want to fix the typos at package.json (in README.me) when building for Windows (preGenerateCommands...), currently copies the same .dll.

Possible fix, you can copy paste the following:

I've had a look through the code and I honestly can't understand why it's saying this.

MDI Support

Hi there, I would like to ask if MDI is supported by the library?
If so, how can that be implemented? Is it using window.window?

One more is getting the width property of a Treeview object. I always get width=1. I am trying to position a window next to a treeview by getting the width property but I am having a problem. I attached a screenshot of the main window. I want a new dialog or window to appear next to the treeview so I took the width of the treeview using getWidth and then passed it to the window to be created using the setGeometry method but I always get 1 as the width.

The code for the project is available at Github

Help would be much appreciated. Thank you!

Build of example fails on Mac OSX 10.11

Multiple assertion failures. The terminal output looks really obfuscated, so I have no idea how to begin.

Color methods have been added to widgets that can't use them

Color methods have been added to widgets that can't use them.

For example, the color mixin has been added to the Entry widget but calling setBackgroundColor doesn't change anything while setForegrounfColor does.

Either find a way to make these work or remove them from widgets where there is not support possibly breaking the mixin up to be more focused.

Text bind (<<Modified>>) only happens once

I was assuming this was like an onChange event for the text element, and it works that way for the first input change. But for subsequent changes no event occurs. Is there a flag that needs to be reset?

example fails on osx

adding a system path to a ComboBox makes it display garbage

ComboBox.setData(["c:\a\b"]) //Garbage

It works if you double escape the backslashes but makes it difficult and error prone to use.
ComboBox.setData(["c:\a\b"])

Example fails to run on Windows but build fine

The build is successful but when I attempt to run it, two error prompts happen. Both have the same message tcl86t.dll is not found. I checked my dub folder in "Appdata/Roaming", and it is found under the dist folder, just fine.

I had no tcl installation so I went to install Activetcl 8.6, but that dll is not there, and it doesn't run. I downloaded the dll from the internet and placed it in the same folder, and only one error prompts occured.

Is there a special build link that I should include if I'm using it from Windows?

Problem with unicode not being used for file and directory dialogs.

Hi,

I'm the d-apt maintainer. I noticed that when running the example, the open file and Directory dialogs do not properly show the file/folder names if they include some accent or another diacritical mark. Is TkD dialogs non compatible with UTF-8?

Here attach you some captures from Debian.

Jordi

How to install this in Windows ?

Compile Tcl/Tk as DLLs for distribution for Windows platforms

Compile Tcl/Tk as DLLs for distribution for Windows platforms. If this is done then the end user does not need Tcl/Tk installed on their machine.

Can't compile under Windows

tkd\dialog\dialog.d(22): Error: class tkd.dialog.dialog.Dialog unable to resolve forward reference in definition

The same is for DirectoryDialog, FontDialog, FileDialog, OpenFileDialog, SaveFileDialog, MessageDialog.
I'm building with DMD 2.064.2.

Windows requires Microsoft Visual C++ Redistributable

On a fresh Windows 10 system, the following files need to be installed, or programs will exit with uninformative error codes:
https://www.microsoft.com/en-us/download/details.aspx?id=30679
https://www.microsoft.com/en-us/download/details.aspx?id=52685
This is often not an issue since many windows programs need these and the end-user is likely to already have them installed. Since no information is provided by the program when they aren't included, it should be noted in the README that these will need to be installed.

Enhancement to the way text widgets use images.

Instead of loading text widget images from disk, convert them to data and embed in the application for distribution.

Add support for correcly implementing commands for buttons.

Correctly implement commands for buttons. Current the only way to get a button to do something is to bind an event. While this works it's not disabled if the button is disabled like a true button command.

Changing Widget Background Color

I was wondering if it is possible to change widget's background color like from Python's Tkinter:

<widget>.configure(backgrounf="red")

Thanks

lib found but undefined references

I havent got much experience with D yet but I got these undefined references - the library should be properly included. https://pastebin.com/neWNdVN3
What am I doing wrong?

OpenGL?

Is it possible to create an OpenGL context inside of a TkD window? Potentially with something like Derelict?

Segmentaiton Fault after Choosing a File via OpenFileDialog

OS: Windows 10
Arch: x64
tkd: 1.1.13
tcl86t.dll: Retrieved from nomad-software/tcltk/dist/x86_64/
tk86t.dll: Retrieved from nomad-software/tcltk/dist/x86_64/

The following code produces a segmentation fault iff one chooses a file in the dialog using its "Open" button. Closing the dialog by clicking the "Cancel" button or closing its window will not trigger anything untoward.

auto ofd = new OpenFileDialog("Open file")
        .show();

Below is the output from gdb.

Thread 1 received signal SIGSEGV, Segmentation fault.
0x0000000068f51ef8 in tk86t!TkGetCursorByName () from path/to/project/tk86t.dll

Hopefully the referenced function will give you an idea, because I haven't been able to do much with it.
I've also tried using 8.6.>6 binaries, but then, while the OpenFileDialog doesn't produce issues, merely exiting the application will precipitate a segmentation fault. I have no idea if you can do anything, but I'm at a loss.

Kind regards,

Implement D methods that scrollbars use instead of delegating to Tcl/Tk

Currently when attaching a scrollbar to a widget or vice-versa the actual communication between them is delegated directly through to Tcl/Tk. It would be nice to have these implemented in D so they can be overridden. This would be handy if you want to create custom widgets purely in D.

Fix potential for dangling pointers in Element.createCommand.

Because the garbage collector cleans up during runtime it may free uniqueData and callback inside the CommandArgs struct when creating a new command. Check and alter the behaviour of the Element.createCommand method to not allow this.

start TK in D Programming !

Hi there,
i am completely new in D Programming and only want to start the example code for TK that is described HERE on the homepage.
For this i have gitcloned the 3 packages tcltk tkd x11 in the folder /usr/local/GIT/.
Then i run the command dub inside any single folder and build it.

When i want to run the example TK D script the following results are seen -

$ dmd -I/usr/local/GIT/ hw_graphical2.d
hw_graphical2.d(1): Error: module tkdapplication is in file 'tkd/tkdapplication.d' which cannot be read
import path[0] = /usr/local/GIT/
import path[1] = /usr/include/dmd/phobos
import path[2] = /usr/include/dmd/druntime/import
hans@mx1:~/Documents/D_lang
$

I have made something wrong with the configuration of the TKD module.
Need help here to start programming with D and TK.

Undefined symbol InversionList in std.uni

I had to update to phobos head for some reasons and now I'm getting these errors:

I'm not sure where you may be using std.uni, this library is quite big O_o

Investigate a way to clean up image and textvariable data from the interpreter.

Investigate a way to clean up image and textvariable data from the interpreter. e.g. When image objects are created they create an image in the interpreter. When the image object falls out of scope and is collected, the image is still in the interpreter. Fix this if poss.

Some control's default background colors are wrong

A few of the controls have their background colors set incorrectly by default (presumably using a hard-coded white instead of the proper system color for control backgrounds). Aside from not looking good, this can also result in invisible text:

Not sure if this is just Windows or if it's happening on other platforms too.

Feature Request: add OpenGL capabilites

Sorry, I do not want to misuse the "Issues" section. But it would
be a nice extension if it were possible to have a modern OpenGL
accelerated widget. Maybe throwing in some Tcl3D (http://www.tcl3d.org)?
