Hello, I am currently trying to design a customized VBox widget
that will have a gradient background. So I created a custom widget over the
GtkVBox widget, and replaced the ‘expose’ function of the
GtkWidgetClass to draw the gradient. Everything works well, except when I want
to include this VBox inside a scrolled window. If I use the gtk_scrolled_window_add_with_viewport()
function, the widget is displayed correctly. But when a size allocation occurs
(simply resize the window containing the box with the mouse) the background gets
scrambled (I attached a screenshot. The blue line should be at the bottom of
the window), as if not all the widget was redrawn. If I drag another window of
the box, the widget is once again redrawn correctly. What am I doing wrong ? Thanks in advance! Mathieu |
