#917 Tabs is not redrawn after click on them

[Dmitrij Volin]

After opening a panel (e.g. F2) or build a project, I have been observed un(re)drawn tabs (including whatches window in the debug mode).

Platform: Gentoo Linux x86_64, codeblocks is current from repo.

See attached screenshots.

Build: Feb 7 2020, 07:25:25-wx3.0.4-gcc 9.2.0 (Linux, unicode) - 64 bit; SVN 11957

[Teodor Petrov]

What are the steps to reproduce this? Is this happening in a reliable way?

[Dmitrij Volin]

Thanks for the your reply !

here is videos of it: https://www.youtube.com/watch?v=P_kDn6yB1L4

I have just opening the CB, click on an panel/window and I got unredrawn tabs ((
But if I do resizing the editor or move splitter - then it is redrawing.

What WM/DE are you using? What happens if you compile the wxwidget auidemo sample? Would it work correctly there?

[Teodor Petrov]

Also what is the output of eselect wxwidgets list or wx-config --list ?

[Dmitrij Volin]

What WM/DE are you using?

I have installed KDE-5.64.0

Also what is the output of eselect wxwidgets list or wx-config --list ?

$ wx-config --list
Default config is gtk3-unicode-3.0-gtk3
Default config will be used for output

Alternate matches:
gtk2-unicode-3.0

What happens if you compile the wxwidget auidemo sample? Would it work correctly there?

How can I do it ?

[Dmitrij Volin]

What is auidemo sample? How can I install it ?

[Teodor Petrov]

What happens if you eselect the gtk2 version of wxGTK? Would the problem go away? (you'll have to rebuild Code::Blocks for the change to take effect).

The auidemo is available from samples/auidemo folder of the wxWidgets source code. I'm not sure if there is a way to compile and install wxWidgets samples with the wxGTK ebuild...

[Dmitrij Volin]

I no not know why, but I got crashed compiled with gtk-2 (I have chosen with eselect for gtk2), but there linked with gtk-3:

I need to sleep now. Tomorow I will try compile again...

PS:
Teodor, please, guide me how to make new syntax highlight.
I want to make its for GNU Assembler, and send patch to here.

[Teodor Petrov]

Here you can find some documentation http://wiki.codeblocks.org/index.php/Creating_a_custom_lexer_for_Code::Blocks_editor if you have more questions about this please ask on the forum or open another ticket.

[Teodor Petrov]

I guess the eselect does nothing the piece of code which selects the gtk3 variant is probably in the ebuild. You'll probably have to change it.

[Dmitrij Volin]

While I have compiled the CB with gtk2-unicode-3.0, I got error:
(Scintilla messages here ...): gdk/gdk.h no such file.

Sadly, I have no time for deep dig into CB for fix the unredrawing widgets ((
but by runaway watch sources of the CB I guess: there are many
skip events for prevent flickering, perhaps problem in that...

And there are not optimized redrawing when blinking cursor:
redrawing all editor widget instead of redrawnig only that area where
is cursor (I have seen flickering when many text on page)

[Dmitrij Volin]

And I have no in the portage wxGTK version of 2:

/usr/portage/x11-libs/wxGTK $ ls wx*
wxGTK-3.0.3.ebuild wxGTK-3.0.4.ebuild wxGTK-3.0.4-r2.ebuild wxGTK-3.0.4-r301.ebuild
wxGTK-3.0.3-r300.ebuild wxGTK-3.0.4-r1.ebuild wxGTK-3.0.4-r300.ebuild wxGTK-3.0.4-r302.ebuild

[Teodor Petrov]

wxGTK 3.0 is available in two separate slots - gtk2 and gtk3

# eix wxGTK
[I] x11-libs/wxGTK
     Available versions:
     (3.0)  3.0.4-r2
     (3.0-gtk3) 3.0.4-r302

From this it is clear that r3xx are the gtk3 releases.
C::B from master builds just fine with gtk2... I've not tried the gentoo provided ebuild though...

[Dmitrij Volin]

Thanks for the explaning !

And thanks a lot for the your time spended on my issues !

I will try emerge the wx-gtk2 (wxGTK) from sources for recompile the CB, for now its packages from binary repo..

[Dmitrij Volin]

through the portage I did not get properly linked the CB
with gtk2:

$ wx-config --list
Default config is gtk2-unicode-3.0
Default config will be used for output
Alternate matches:
gtk3-unicode-3.0-gtk3

[Dmitrij Volin]

OK, I have found the solution: after install livecd into virualbox, install then codeblocks and its worked fine ! I will reinstall system !

Sorry for noise ((

[Dmitrij Volin]

I have found switch from gtk3 to gtk2:

$ sudo eselect wxwidgets set 1 (before see output of: $ sudo eselect wxwidgets list )

and change var WX_GTK_VER in ebuild from equal "3.0-gtk3" to "3.0".

ebuild is attached.
