Hello,
as I am trying to port a program written in C using Gtk+ on a Debian
GNU/Linux to MS Windows (using the MingGW32 compiler set) I have a
problem using GtkClipboard.
The program should simply do copy/paste stuff with simple text. While
I can happily use the X Window selection mechanisms (PRIMARY and
CLIPBOARD) on my GNU/Linux box, the copy/paste stuff does not work
with the MS Windows executable.
This is the error message that I get before even trying to use the
clipboard :
Gdk-WARNING ** gdk_selection-win32.c:1068
OpenClipboard failed : Handle de fenêtre non valide
which means that the window handle is not valid.
Now, if I go to the gdk_selection-win32.c file at line 1068 I find the
following (see arrow on the right-hand side margin below) :
void
gdk_win32_selection_add_targets (GdkWindow *owner,
GdkAtom selection,
gint n_targets,
GdkAtom *targets)
{
HWND hwnd;
guint formatid;
gint i;
GSList *convertable_formats, *format;
gboolean has_set_dib = FALSE, has_real_dib = FALSE;
#ifdef G_ENABLE_DEBUG
if (_gdk_debug_flags & GDK_DEBUG_DND)
{
gchar *sel_name = gdk_atom_name (selection);
g_print ("gdk_win32_selection_add_targets: %p: %s: ",
owner ? GDK_WINDOW_HWND (owner) : NULL,
sel_name);
g_free (sel_name);
for (i = 0; i < n_targets; i++)
{
gchar *tgt_name = gdk_atom_name (targets[i]);
g_print ("%s ", tgt_name);
g_free (tgt_name);
}
g_print ("\n");
}
#endif
if (selection != GDK_SELECTION_CLIPBOARD)
return;
if (owner != NULL)
{
if (GDK_WINDOW_DESTROYED (owner))
return;
hwnd = GDK_WINDOW_HWND (owner);
}
if (!API_CALL (OpenClipboard, (hwnd))) <<<<------ line 1068
return;
So it seems that the error message is produced upon execution of the
API_CALL (OpenClipboard, (hwnd))
call, as if the hwnd handle returned by GDK_WINDOW_HWND (owner) were
invalid.
Does anybody encounter this problem ? How could I fix it ?
Thank you for your ideas,
Cheers,
Filippo
