Hello, I'm new to GTK+ programming.I encountered a problem in my program. There is a window which contain more widgets in my program, the widgets were mapped with more pictures(via gtkrc file ). The problem is: if the window is a toplevel window,you would saw flicker phenomenon; if the window is a popup window,you wouldn't saw flicker phenomenon,and mapped normally(no flikcer phenomenon). The flicker phenomenon not serious,but you could saw it with eyes.and popup window mapped normally( Why ?). The version of gtk is gtk+ - 2.12.9 (the OS is ubuntu 8.04 ), and it already set double buffer mechanism. How could I do to avoid flicker phenomenon ?
