Hi!
I try compile library with fpc 3.1.1 but return below error !
cef3lib.pas(1002,44) Error: Incompatible type for arg no. 2: Got "TStringSplitOptions", expected "QWord"

Hi,
I am trying to adopt fpCEF3 for osx (Carbon widgets). I am able to load libraries but then app crashed.
Any pointing me is welcomed.
Thanks

Hello!
I'm try to use fpCef3 in Linux Mint 17.3 (x32), but I cannot find compiled binaries with malloc disabled for version 3.2556.
I download sources for version 3.2556 and try to compile it using Code:Blocks IDE (compiling was success), but I don't know how to disable malloc. Can You help me to do it, please?
P.S. Sorry for my English

Plugins not works, SIGSEGV.Here is my code:
var
cefplugins: TCefString;
...
Finalize(cefplugins);
cefplugins.str := PChar16('/plugin/');
cefplugins.length := sizeof(cefplugins.str);
cef_add_web_plugin_directory(@cefplugins);
cef_refresh_web_plugins;

I try use functions from cef3lib but i take SIGSEGV.Here is my code:
CefAddWebPluginPath(ExtractFilePath(Application.ExeName) + 'plugins/');

Hi,

I was trying to make a Lazarus UI calling a JavaScript function and get the return result.
I was following the C++ example here:

https://bitbucket.org/chromiumembedded/cef/wiki/JavaScriptIntegration

to register a JavaScript callback to the Lazarus-side and trying to call the callback later.
An exception was thrown without luck.

Do you have any example how to do this properly?

1. libcef.so requires libudev.so.0, which is not available but can be symlinked from libudev.so.1.6.2, so you might want to add that to the "How to get started"
2. After 1 is solved, executing LCLSimple demo now results in:

I'm a bit lost here since I don't know what "locale" thing is expected here, because it doesn't seem to be related to /etc/locale.gen.

New version with 64 bit.. please use this to add support..

I see that chromium included some kind of pdf reader, i dont want to use it.

There is some way to force chromium to execute a external program for this pdf or to start download?

Thank you so much.

any advisement plz~

Why is TChromiumFontOptions.StandardFontFamily read only?
IMO, it is writable.

Please add a simple multi tab browser example.
What QtWebKit have. http://users.telenet.be/Jan.Van.hijfte/qtforfpc/fpcqt4.html (at the bottom)
Using TPageControl. LCL doesn’t support nboShowCloseButtons which QT does, but it doesn't matter. I just want multi tab.
And also cookies, proxy, authentication, flash......
Thank you very much.

Hi
I using fpCef3 in ubuntu and FPC 3.1.1.
when running application with chromium component,new window open and don't show anything and when close application raise below exception.

Project CefClient raised exception class 'External: SIGABRT'.

In file '../nptl/sysdeps/unix/sysv/linux/raise.c' at line 56

thank you.

I am having a issue with fpCEF3.

In windows i can create a project fine and add the component Chromium pointed to https://www.google.com.br, but in Linux (Debian 8), when i try to do that, the component detaches from the main window, the loading of google occurs fine but in a another strange window.

I am going crazy because there is no errors at all.

What i do:
1- Create a new project from zero.
2- Copy resources and release to the root of the project.
3- Add a Chromium component to the main form.
4- Set default url to https://www.google.com.br in the component properties.

What happen if a compile and run it on:
1- Windows: It opens only a window with chromium component loading google in the main form.

2- Linux - It opens 2 windows, the main form , and a new additional window, loading google fine but in a new detached window.

And the strangest thing is that the LCLsimple example, works in the same window **but it broken openning a new window, when i remove the simpletext component from the example app. (yes! the 'Url:' text)

Maybe is something related to the lazarus version?

Lazarus 1.6 FPCEF for CEF 2743 Debian 8 64 bits operating system, graphical environment: Mate

Update please.

Please update to build 1916. Also is UNICODE switch supported?

Good day,
fpCEF3 worked fine a few months ago (Linux + Windows 8.1), Lazarus 1.6
What have changed is Lazarus: v1.6.2

When running any app using fpCEF3, including the examples, I always get the assembler window with 'libcef!GetHandleVerifier'. So I downloaded the last version of fpCEF3, and cef_binary_3.2743.1449.g90ba67d_windows32 : same issue!
(screenshot attached)

Do you know how to solve this one? Thaks in advance

Follow-up of issue #39.

• TCefPrintHandlerOwn
• implement printing to PDF for Linux in LCLCefClient
• add general Linux printing support in LCLCefClient (very low priority)

Hi,

The Object Inspector contains onKeyEvent.

Do you plan to make handling mouse events (onMouseEvent)?

I did not find examples of intercepting mouse events for TChromium
(Interested five buttons - 3 standard and 2 side).

Best Regards,

waspace/wacef is most useful delphi cef3 framework, it helps me a lot at my work than other you. I don't see any about you guys' license of your free pascal project. You have no evidence to demand they delete the most useful cef3 project!

TChromiumFontOptions.StandardFontFamily, FixedFontFamily or etc is type of String.
The correct type is not String but ustring?
(Or need using UTF8Decode in GetFontFamily and SetFontFamily method.)
many "Warning: Implicit string type conversion with potential data loss from "WideString" to "AnsiString" " is up in Lazarus trunc with FPC3.0.0RC2.

Hi dliw,

Thanks for you great project. Just giving you a heads up that tcmalloc is now disabled in official linux builds - https://bitbucket.org/chromiumembedded/cef/wiki/AutomatedBuildSetup#markdown-header-linux-configuration. Official builds that disable tcmalloc are located at http://opensource.spotify.com/cefbuilds/index.html.

Since your readme.md mentions otherwise I'd figure I'd let you know about the recent change. Wasn't sure how else to reach you so hope you don't mind me opening an issue.

In the CEF C++ documentation there is a way to create a function:

CefV8Value::CreateFunction("myfunc", handler);

(a native function that then can be called by Javascript code, AFAIK)

Is there anything equivalent for freepascal/lazarus ?
I was thinking RTTI was the way, but not sure, there are probably multiple ways, as CEF is quite complex of an API.

From the documentation:
"CEF supports the creation of JS functions with native implementations. Functions are created using the CefV8Value::CreateFunction()"

https://bitbucket.org/chromiumembedded/cef/wiki/JavaScriptIntegration.md#markdown-header-js-functions

Also, do you accept Donations (money) for your great contributions to this project :-) and thanks for making it work with fpc

The Download dialog does not work in Linux. If you click in a file, for example a .doc file, in Windows a dialog will open using fpcef, but in Linux, nothing happen, and there is no errors.

There is some way to get this working?

Where do I download the version of the binary file?

Hi,
I want to realize response content filtering, see related functions and interfaces, such as cef_response_filter_filter, TCefResponseFilterOwn., but I do not know how to use, would you please tell me the use of methods, or to provide a corresponding demo, thank you very much.

I think I encounter quite an annoying behavior of fpCEF3 which happens when restoring App Window from taskbar, after pressing 'Show Desktop'. When restoring, and the App Window shows up, there I notice the Chromium content seems to be rendered multiple times (more than once). May be due to WM_RESIZE processing?

This behavior neither occur with any Delphi CEF3.* nor with Linux version of Lazarus 1.6 (with the same 3,2526 source). For simple reproduce, please browse using fpCEF3 to http://www.yahoo.com then click 'Show Desktop' to hide all windows, and then try restore App Window from taskbar. You should see what I said above.

If that's a bug, I'm really hoping this can be fixed. Thank you very much in advance.

Hi.

I've tried to compile this package with Lazarus 1.6.2 and fpc 3.0
The following error occurs: Unknown property: "TabOrder".

Please help.
Thank you.

Was wondering about TCefRTTIExtension, and it seems you commented it out.
Was it because fpc is not ready for this code, which originally came from the Delphi CEF3 project? Or for another reason? (likely TValue not compatible with fpc)

Also are there alternatives to TCefRTTIExtension that are superior so less need for it?

Hi,
Try to install lpk, but got an error message on compiling:
"cef3lcl.pas(615,15) Error: Illegal type conversion: "TMessage" to "TWMKey"

Any idea?

Hello,

I'm trying to use fpCEF on Windows, but it raises the following error:

Unknown Run-Time error : 255.

And creates the log:

I believe that I'm using the wrong version of CEF library. My package is cef_binary_3.2556.1368.g535c4fb_windows32.7z, downloaded from https://cefbuilds.com/, and I just unpacked it into my EXE directory.

So, what's the CEF lib version to use?

Thank you!

Following code is needed to make examples execute in my environment.

Code:
//Add to TMainform.FormCreate
CefResourcesDirPath:='Resources';
CefLocalesDirPath:='Resources\locales';
CefInitDefault;

My Environment:
Windows7 32bit
Lazarus 1.4.4
CEF 3.1750
I am using fpCEF for CEF 3.1750. Because new for 3.2454 can not run in my environment. ;-(

Thank you so much for your great work.

Thank you ! Now the download works like a charm. I want to know if there is a way of wait the download completes before i run the next command:

    files.Add('/tmp/lastfile.pdf');      

    FreeAndNil(files);

    RunCommand('/usr/bin/evince',['/tmp/lastfile.pdf'], s);   

It is running the command at the same time the file is being saved or something like this.

When i try to print the printer dialog did not appear. In Windows it is working fine.

All Linux programs are able to print, so is not a issue with cups i think.

No error messages, even if i run the app from a terminal.

Is Generic Message Router (https://bitbucket.org/chromiumembedded/cef/wiki/GeneralUsage#markdown-header-generic-message-router) implemented in fpCEF ?
I may not be able to find it in sources.
Thank you very much for reply.

Hi
I try to run GT2Minimal Example with lazarus 1.4.0 and freepascal 2.6.4 on ubuntu 14.04 and cef library version 3.2171.1979 but after application run a "Unsupported CEF library version " exception raised.

I dragged Chromium into Window Design directly, throw 255 exception at runtime

I followed the steps but I can't get the component to work. First it complains about missing properties like taborder. That line is made to comment for some reason so easy to fix. then it complains about missing backgroundcolor, adding a dummy fixes this issue. Than the debugger breaks on every cef_time_to_timet, and finally an empty browser screen appears, but it does not load any url. Not sure if it's a bug or not, but since this is my n-th attempt to get this working for various versions I still don't get it what I'm doing wrong or not. I loaded the 32 bits version and targetted the stuf to 32 bits.

I also redid the full installation and changed widgetset to w32 which solved the property issue. But I still can't get a webpage to show.

Amendment:
it does not work only for the start page as soon as the application starts.
After change the URL, this option works correctly.
This led me astray, sorry.
Please delete this issue

Setting "STATE_DISABLED" for JavascriptCloseWindows option -
it works when the JS-code is executed through ExecuteJavaScript(),
but does not work when window.close() is contained in the source code of web page.

When TChromium component is contained on the main form,
the window.close() method may close the Lazarus application.

I can perform JS-method window.close() in the code of any web page,
in an attempt to close the Lazarus application,
or to try to cause problems for any frames Chromium.

How can I understand that the window (frame) is closed by the user?
Only through the confirmation dialog when processing a OnClose event?

P.S. Sorry for my English

This is an awesome project! May I suggest to add off screen support (for Windows primarily, just my personal case) like what dcef3 does? Thanks.

PS, I noticed you guys have discussed this in another issue, but this is an feature request, so I opening this as a separated one :)

Hi,

Can you put the DLLs that match your source? I tried downloading from the address you provided, but it does not work, obviously others have the same problem(https://plus.google.com/u/2/115143382472228750230/posts/7PDbQtsi8Zc).

Thanks.

Hi,

As in title. I can drop TChromium on pages and it work fine at design time but when run program then all TChromium instances have main window as parent
