Can not SetBackgroundcolour in a wxTextCtrl

Toni_Brkic · April 12, 2004, 6:57pm

How do I know if I use themes? And how do I a remove
the themes?

I am using Suse 9.0 with wxpython 2.4.1.2 (I had it wrong in my first post).

But I have also a wxpython app running on my machine that has the
background colour set in the textctrl.

Are you using themes?

Hi,

I cant manage to set the background colour in wxTextCtrl.
I have made the smallest app possible that shows my problem.
If you run the code the text_ctrl is still white even
though I have done SetBackgroundColour on the text ctrl.

I have also tried with Refresh after setting the background.

Does anybody have an idea. I am quite sure it works, since
I've seen wxPython apps that does it.

I am using wxPython 2.4.2.4 on Linux.

Best regards,

Toni

Some GTK themes do not allow the widgets colours to be changed. Try removing or renaming ~/.gtkrc to find out if this is the problem.

I removed .gtkrc and I use kde and did this

# If you do not want KDE to override your GTK settings, select
# Appearance & Themes -> Colors in the Control Center and disable the checkbox
# "Apply colors to non-KDE applications"

···

#

but I still get that it flashes green for a moment and then
is set to white again.

The strange thing is that it works if I stat the app remotely over
ssh. So I am at work and do ssh to my home computer it works. If
copy the app to my workcomputer and start it there it doesnt work.

I found the problem, it is KDE that forces the colours
on the wxpython app.

I dont know how to disable it though.
I unchecked the 'Apply colors to non-KDE applications' but
is still doesnt work.

Is it possible to override default background colour?

It was that I used a theme.

What I found out in the end is
that there is an ENV variable $GTK_RC_FILES which points
to several gtkrc files. I guess that when you start an app
is that it goes through the list of files in this variable and applies
them.

So what I did was:
setenv GTK_RC_FILES ""

and now it worked.

The bad thing is that it doesnt seem that it is possible to
override the theme from wxPython. So I cant guarantee that
the textfield has another colour.

I wanted to use the textfield so that when it is not editable
it should be greyed out. Is there any other way of doing it?
For example could one hint to gtk that the textfield is inactive
and that it should use the colour for inactive??

textfield.Enable(False) works for me
