Linux : Some GTK2 demos crash

[salvadordf]

Some GTK2 demos crash because the process is mixing GTK3 and GTK2 symbols.
They need to be converted to GTK3.

How to solve this problem? Compile CEF yourself? Or change to GTK3 or GTK2 in CEF4Delphi.

Last time I checked it was possible to build the CEF binaries to fix this GTK3 dependency but I think the best solution is to move to a newer GTK version.

I still need to confirm this but I think I'll have to make some changes in the Lazarus components to support GTK3.

Use the previous CEF4Delphi releases if you need to embed a CEF browser in Linux now while I make some GTK3 support improvements.

The CEF 125 binaries changed the initialization and now more GTK2 demos work again.

CEF 125 二进制文件更改了初始化，现在更多的 GTK2 演示可以再次工作。

Thank you for letting me know. I have already run it in the Linux GTK2 environment and it seems to be working fine so far. I'll do some more testing and then update the Energy framework.

Under GTK2, it is still not possible to switch Chinese input methods and input Chinese

Is there any good solution for switching Chinese input method and supporting Chinese input for Linux GTK2?

GlobalCEFApp.AcceptLanguageList works fine in Linux.

GlobalCEFApp.Locale doesn't work in Linux and you need to use environment variables as stated in the code comments :
` /// The locale string that will be passed to WebKit. If empty the default
/// locale of "en-US" will be used. This value is ignored on Linux where
/// locale is determined using environment variable parsing with the
/// precedence order: LANGUAGE, LC_ALL, LC_MESSAGES and LANG. Also
/// configurable using the "lang" command-line switch.

Use TChromiumCore.SpellCheckerDicts to use a custom language for the spell checker. Call TChromiumCore.UpdatePreferences after setting this property.

I haven't tried the Emulation.setLocaleOverride DevTools command but perhaps it could be used in this case.

Please, use our forum for questions.

Chromium supports both GTK3 and GTK4 currently (code here) and it's switching to GTK4.

I would suggest that all Lazarus apps for Linux migrate to GTK3, QT5 or QT6 if you want to embed a CEF browser.
