Re: Wrapped GdkWindow* resize issues

No, I don't know how to force gdk to process resize events.

If you cc gtkmm-list in your reply, you give other subscribers a chance to answer your question. But in this case you may have better luck on one of the gtk+ lists, such as gtk-app-devel-list.

Kjell,

Thanks for the info.  Do you know of some magic to force gdk to process resize events?  I need some way of syncing the window sizes between the actual window and the GdkWindow.

I found some info at https://developer.gnome.org/gdk2/2.24/ and subpages. Don't know if it's relevant.

#define gdk_window_get_size            gdk_drawable_get_size

From the description of gdk_drawable_get_size():

On the X11 platform, if drawable is a GdkWindow, the returned size is the size reported in the most-recently-processed configure event, rather than the current size on the X server.

From the description of gdk_window_get_geometry():

On the X11 platform, the geometry is obtained from the X server, so reflects the latest position of window; this may be out-of-sync with the position of window delivered in the most-recently-processed GdkEventConfigure. gdk_window_get_position() in contrast gets the position from the most recent configure event.
