Hi,
I have a custom GTK widget which renders using Cairo. In the expose
callback gtk_widget_get_style is called to obtain colours to render
the widget with some theme consistency.
When a theme is changed (ie using gtk-chtheme) any of my custom
widgets that are visible are not updated. However, af

Hi,
I've got a problem with the "selection-changed" signal being emitted
as soon as gtk_dialog_run is called on a GtkFileChooserDialog. I tried
delaying connection of the callback until right before calling
gtk_dialog_run but there were still four calls (in a row AFAICT) to
the callback.

Hi,
It appears that the 'irregularly shaped' windows which used to be
possible by using now-deprecated GDK code even without full
compositing available, are no longer possible using non-deprecated
code.
Using the old deprecated code, a GdkRegion could be created with the

Hi,
I have a custom widget I've created which uses widgets from a 3rd
party library. When I use gtk_widget_set_sensitive(my_widget, FALSE),
some of the widgets from the other library remain sensitive.
Is this a bug in the 3rd party library?
Or should I be using a callback to handle the "state-ch

Hi,
I'm a little confused over destruction of my custom widgets. I'm
mainly looking at existing code for how to do things as I've found the
docs (via DevHelp) difficult to understand and to garner an idea of
when and what is needed.
Here's some typical code for one of the widgets which is (typica

Hi,
(forgive some imprecise names here, am writing from memory and in a

I'm adapting some code which uses gobject to create a widget. The code
previously used GtkWidget as the parent_class but I am trying to adapt
it to GtkDrawingArea as the parent_class.
However, the button_pr

Hi,
I'm trying to modify some existing code which uses gobject so that the
function to create a new object can take a parameter. The existing
code is quite simple, and my modifications simplify it further so I
don't want to spend a great deal of time messing about with Gobject
things.

What about all the errors/warnings, have they gone, or do they still appear?

Hi,
As from my previous email, I require the dimensions of the scrolled

window being resized) by using the 'changed' signal emitted by the

So I create two user functions one for when windo

I see that some GDK drawing functions and graphics contexts have been

Yesterday I spent a few hours *removing* Cairo code from my fledgling
