Clear Clipboard on KDE

Question

I am using gtk to clear the clipboard on Linux platforms with X11, and I was hoping that it would work across all Linux platforms. However, my gtk code does not work for Fedora KDE and some distributions of Fedora. When clipboard_clear function is called, the clipboard does not get cleared.

void clipboard_clear() {
  gtk_init(&args,NULL);
  GtkClipboard* cb = gtk_clipboard_get(GDK_SELECTION_PRIMARY);
  gtk_clipboard_clear(cb);
  gtk_clipboard_set_text(cb, "", 0);

  cb = gtk_clipboard_get(GDK_SELECTION_CLIPBOARD);
  gtk_clipboard_clear(cb);
  gtk_clipboard_set_text(cb, "", 0);
}

Is there anything that I can do to make this gtk implementation work as it suppose to on a Fedora KDE? If not, are there any libraries that can clear the clipboard on KDE and be statically linked? (Qt is not one among them because of licensing restrictions.)

Answer 1

External clipboard managers prevent the above code from clearing the clipboard.

On Fedora 19 KDE, klipper came pre-installed. After closing it, there wasn't any more problems with clearing the function. Similarly on Fedora 19 LXDE, clipit came pre-installed.
