Hi all,
I'm trying to share application-specific data between my program
instances using the gtk.Clipboard and a custom target to
distinguish it from normal text.
I found a workaround which appears to work: use
gtk.gdk.SELECTION_TYPE_BITMAP for the target type instead of STRING.
def get_f(clipboard, selection, target_handle, userdata):
selection.set(gtk.gdk.SELECTION_TYPE_BITMAP, 8, "Hello there")
I don't know whether this type guarantees that the data will to be
copied verbatim.
regards,
Richard.
The following snippets work on linux but not on win32, where it
gives the warning:
copy:13: GtkWarning: gdk_property_change: assertion `type !=
GDK_TARGET_STRING' failed
This appears to come from gdk/win32/gdkproperty-win32.c
Has anyone used custom selection targets under win32 with more
success?
regards,
Richard.
