Hello,
I've found out that implementation of GDK_WINDOW_OFFSCREEN has some
unimplemented functions. This approach makes debbuging and searching
for bugs really hard.
IMHO all function should be implemented, even if an implementation is dummy.
A proposed patch is attached. It's only proposal, but it works for me.
How did I get this opinion?
I use KDE desktop with oxygen-gtk widget style for GTK+ apps. I wanted to use
glade-3.13.0 but glade is always crashing after clicking on the Window icon
from the Toplevels toolbar.
What happens:
1. glade creates an offscreen window
glade_design_layout_realize() : gladeui/glade-design-layout.c : 1630
attributes.window_type = GDK_WINDOW_OFFSCREEN;
2.
glade_design_layout_realize() : gladeui/glade-design-layout.c : 1644
ipriv->offscreen_window = gdk_window_new (gtk_widget_get_root_window (widget),
&attributes, attributes_mask);
3.
gdk_window_new () : gdk/gdkwindow.c 11375
if (gdk_window_is_offscreen (window))
{
_gdk_offscreen_window_new (window, attributes, attributes_mask);
4.
gdk_window_is_offscreen() : gdk/gdkwindow.c : 11375
static gboolean
gdk_window_is_offscreen (GdkWindow *window)
{
return window->window_type == GDK_WINDOW_OFFSCREEN;
}
5.
_gdk_offscreen_window_new() : gdk/gdkoffscreenwindow.c : 803
window->impl = g_object_new (GDK_TYPE_OFFSCREEN_WINDOW, NULL);
6.
gdk_offscreen_window_class_init() : gdk/gdkoffscreenwindow.c : 766
impl_class->get_frame_extents = NULL;
-- Set implementation function to NULL.
-- And finally.
7.
Gtk::gdk_toplevel_get_frame_size() : src/oxygengtkutils.cpp : 882
gdk_window_get_frame_extents( topLevel, &rect );
8.
gdk_window_get_frame_extents() : gdk/gdkwindow.c : 10443
GDK_WINDOW_IMPL_GET_CLASS (window->impl)->get_frame_extents (window, rect);
-- Ooops, get_frame_extents is NULL here
I'm not sure if implementation of oxygen-gtk should have special casing
for GDK_WINDOW_OFFSCREEN like the following:
if( GdkWindow* topLevel = gdk_window_get_toplevel( window ) )
{
if( GTK_IS_OFFSCREEN_WINDOW( topLevel ) )
{
if( w ) *w = gdk_window_get_width(topLevel);
if( h ) *h = gdk_window_get_height(topLevel);
}
else
{
GdkRectangle rect = {0, 0, -1, -1};
gdk_window_get_frame_extents( topLevel, &rect );
if( w ) *w = rect.width;
if( h ) *h = rect.height;
}
}
