Chromium Embedded Framework for Free Pascal

fpCEF3

Chromium Embedded Framework for Free Pascal

How to get started

• Install cef3.lpk into Lazarus
• Download CEF3 (standard or minimal distribution). Make sure to use the correct CEF3 version (see the changelog / release tag); other versions (older or newer) usually don't work and are not recommended
• Create a new project or use one of the projects in the Examples folder. LCLSimple is a good starting point
• Read the following section on how to correctly set up the file layout

Important:
Most examples use build modes. Make sure to select the correct one, otherwise compilation will fail.

CEF setup

macOS

Follow the instructions on the wiki.

Windows and Linux

A CEF package contains

• the CEF library itself and related binaries in the Release or Debug folder and
• resources in the Resources folder.

By default CEF expects the library and binaries in PATH (Windows) or LD_LIBRARY_PATH (Linux) and the the resources in the same folder as the executable. A custom path for the library can be set using CefLibraryDirPath. The path for the resources can be changed by setting CefResourcesDirPath and CefLocalesDirPath. However, some files cannot be moved:

Windows

• chrome_elf.dll has to be in PATH or the same folder as the executable
• icudtl.dat has to be in PATH

Linux

• icudtl.dat and *_blob.bin have to be in the same folder as the executable

Important:
Make sure to include cthreads as the first unit in your main program.
If you build CEF3 yourself make sure tcmalloc is disabled.

Hints

Don't use --single-process or change CefSingleProcess to True. This mode is not officially supported by Chromium.

If the browser goes "blank" (e.g. when loading a page), the render process crashed. See Debugging on how to debug the render process. The render process restarts automatically on the next page request.

SubProcess

If CEF is initialized a subprocess is started. By default a second instance of the main program is used as the subprocess. Nevertheless, the preferred way is to define an own (minimal) subprocess executable. In fpCEF3 this can be done by setting CefBrowserSubprocessPath to the path of the subprocess executable. In the LCLSimple example this setting can be found in the Initialization section at the end of main.pas.

A minimal subprocess can be found in the folder /Examples/SubProcess. The subprocess also needs the CEF3 library and resources in its path, so it is recommended to put the subprocess executable in the same folder as the main exe.
More details can be found here.

Debugging

Sometimes it is useful to debug the subprocesses spawned by cef. On Linux this can be done by adding

--renderer-cmd-prefix='xterm -title renderer -e gdb --args'

to the command line.
Further details can be found here.

Supported platforms

• Windows
• Linux (Gtk2 or Qt4)
• macOS (Cocoa)

Documentation

You can find comments and usage information in

• cef3lib.pas / cef3api.pas
• the example projects in the Examples folder
• the official api docs here
• the official cefclient example program here

fpcef3's Issues

make examples execute in my environment

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.

tcmalloc is now disabled in official builds

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.

FPCEF3 printer dialog not showing on Debian 8 Linux

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.

JavaScript window.close() method may close the application

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?

Couldn't find the DLL that matches the source

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.

Question: Generic Message Router ?

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.

Update please.

Add off-screen support

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 :)

multi tab browser

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.

Component is jumping to a new window only in Linux

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?

Assembler window: libcef!GetHandleVerifier

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

Download dialog does not work in Linux

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?

Chromium behavior when restoring Application window

Hello,
I'm testing CEF 3.2526 in Lazarus 1.6 on Windows XP 32-bit. 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.

Can't get it to work on windows

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.

Is string type correct?

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.)

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.

CefV8Value::CreateFunction() equivalent in FPC

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

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.

What's the CEF lib version to use?

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!

TCefRTTIExtension commented out in cef3own.pas

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?

How does Lazarus UI call a JavaScript function?

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?

Why is TChromiumFontOptions.StandardFontFamily read only?

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