Hi,

My OpenGL (GLCtrl) based applications now crash on startup. I did a full rebuild, but still the result is this:

tom@tom-LM-WMV:~/upp.out/program52/CLANG.Gui.Shared$ ./GLModeler 
(GLModeler:5955): Gtk-ERROR **: 10:07:31.280: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported
Trace/breakpoint trap (core dumped)
tom@tom-LM-WMV:~/upp.out/program52/CLANG.Gui.Shared$

Here's the backtrace:

Am I doing something wrong here? (I have not changed anything in my code and it used to work on Linux. It still works on Windows.)

Best regards,

Tom

...

Can you retry now? I have removed dependency on gtkglext, which we are not using anyway.

If it still does not work, do non-GL examples work for you?

This sounds like lot of fun.

I guess dropping support for status icons in Gtk is legitimate option, as that's how the Gnome authors envision it and how they want it.

But as a KDE user, I would prefer if there were still APIs and tools in U++ to handle status icons normally.

But U++ is GTK3 based now, so ... I don't know. Maybe the X11 without GTK branch only to keep them supported and GTK3 branch to ignore any U++ API calls?

Seems quite awkward situation to me, I definitely like existence of status icons in the task bar in my desktop environment, and if some app is overusing it, I can uninstall the particular app. But I don't understand Gnome design decisions for many years, so this is just another one, I simply think completely differently about my computer "desk".

There is a difference (marked with red rectangle) between OptionBox of TestChStyle and checkbutton of gtk3-widget-factory. The ✔ mark of OptionBox looks more blurry compared to checkbutton.

Checked for 13910 svn revision. The ✔ mark of OptionBox is not blurry as before, but the the size of its background image is smaller, if compare to checkbutton of gtk3-widget-factory.

Hello Mirek,

Apps that are compiled now and TheIDE itself have unusual (swapped) location of buttons OK and Cancel in standard dialogs.

In old gtk2 versions in file ChGtk.cpp:
SwapOKCancel_Write(!Qt);

Now there is nothing like this.

Best regards,

You must install pkg-config manually (using the distro package manager) as it's not installed by default when you install other devel packages.

If U++ uses GTK3 only, x11 or libnotify are not required.
<..>
So if I'm not wrong, this part of the patch is incorrect:
<..>
and should be replaced by

-pkg_config((LINUX | FREEBSD) !X11) "gtk+-3.0 libnotify";
+pkg_config(POSIX !X11 (!OSX | OSX11)) "gtk+-3.0 libnotify";

Linking...
