gtk_tree_model_filter_set_visible_func() is checking for
priv->visible_func, but that is always going to be NULL since there's
no way to call this function twice.
Besides that the code itself is wrong, since it tries to call
priv->visible_destroy without making sure that it's not NULL
Bypassed with #if 0 because it is an awful hack and not really
acceptable from a privacy point of view for instance. It prevents
Firefox from deleting temporary files containing images being dragged,
so they stay on disk. Bug #561973.
GdkNativeWindow cast is needed in 64-bit Windows so gpointer data
is converted to a (64-bit) native window handle.
GPOINTER_TO_UINT() is used in other platforms.
GPOINTER_TO_UINT() *does* drop the upper 32 bits on 64-bit
Windows. After all, it by definition produces a (32-bit) unsigned int.
The GLib commit mentioned in the reverted commit's log message just
means that it does this without any compiler warning about casting
from pointer to integer of smaller size, as it first casts to a 64-bit
integer, then casts that to a (32-bit) int.
We must use the GdkNativeWindow cast here so that on 64-bit Windows
the gpointer data in embedded_list is converted to a (64-bit) native
window handle without going through 32-bit truncation. If ifdefs are
required to avoid compiler warnings on X11, so be it then. Probably it
would be best to introduce a GDK_GPOINTER_TO_NATIVE_WINDOW() macro in
gdktypes.h.
This reverts commit 78151dc7d4.
Add support for putting widgets in the tab area, before or after
the tabs. This was requested a long time ago in bug 116650. The
implementation is the work of Johannes Schmid.
Either g_type_register_static_simple (used by G_DEFINE_TYPE_EXTENDED)
and G_IMPLEMENT_INTERFACE use automatic variables for GTypeInfo and
GInterfaceInfo structs, while tutorials and source code often use
static variables. This commit consistently adopts the former method.
