Dear Gtk-perlers, In developing a drawing program in gtk2-perl, I've met a strange situation.
I have a Gtk2::DrawingArea inside a Gtk2::Viewport inside a Gtk2::ScrolledWindow inside a Gtk2::HBox inside a Gtk2::Table inside a Gtk2::Window. I would like the DrawingArea (that contains a Cairo Surface) to be redrawn each time the user clicks on it. Since the other elements in the table are not changing, I have tried calling $My_Drawing_Area->queue_draw(); or $My_Drawing_Area->queue_draw_area(0,0,1000,1000); to make the expose sub redraw that part of the window. While this works fine on one system I have (opensuse 13.1, i586), on another system (also opensuse 13.1, but x86_64), the program crashes with a "BadDrawable" X error: The error was 'BadDrawable (invalid Pixmap or Window parameter)'. (Details: serial 1718 error_code 9 request_code 62 minor_code 0) I get the expected behaviour (i.e. no crash) on both system if I replace the above command by $My_Main_Window->queue_draw(); or by $My_Main_Window->queue_draw_area(0,0,1000,1000); Am I having luck that the $My_Drawing_Area->queue_draw() works on one system, or is there a bug somewhere? Also I wonder about the sanity of calling $My_Main_Window->queue_draw_area(0,0,1000,1000); In, say, a 500x500 window (even if it contains a 2000x2000 drawing area as described above). Any idea?
