Re: XTestFakeKeyEvent GDK-equivalent
For quick hacks or testing apps, I use xdotool. I've no idea if it works with Wayland though. -- James Cameron http://quozl.netrek.org/ ___ gtk-list mailing list gtk-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-list

I tried your code out. It works OK, but its limited to emitting events to a GTK managed window and what I really wanted was to insert events into the X11/Wayland Display server, so that any application which has the focus could receive the events. Maybe that is not possible within GTK and I need to access lower-level libraries like X/Wayland? Yes, I expect so. It occurred to me after posting my variant code that it would not do what you wanted, if you're looking to send keystrokes to some arbitrary target outside of your GTK application. It seems pretty clear that if you want to send to an arbitrary X11 (or Wayland) window you'd need an API that gives you an ID for that window, at least. -- Allin Cottrell Department of Economics Wake Forest University ___ gtk-list mailing list gtk-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-list

Hey, Eric. I've just tried that function, it didn't do anything, I'm attaching
my code so you can see if I'm doing this wrong.
#include
#include
#include
GdkWindow* gSuperWindow;
static gboolean
press_key (gpointer data)
{
GdkWindow *window;
GdkModifierType NO_MODIFIER = (GdkModifierType) 0;
int* c = (int *) data;
window = gdk_get_default_root_window();
gdk_test_simulate_key (gSuperWindow, -1, -1, GDK_KEY_a, NO_MODIFIER,
GDK_KEY_PRESS);
gdk_test_simulate_key (gSuperWindow, -1, -1, GDK_KEY_a, NO_MODIFIER,
GDK_KEY_RELEASE);
(*c)++;
printf("Char printed\n");
if (*c < 10) {
return TRUE;
} else {
return FALSE;
}
}
static void
activate (GApplication* app)
{
GtkWidget* window;
GtkWidget* text;
window = gtk_application_window_new (GTK_APPLICATION (app));
text = gtk_entry_new ();
gtk_container_add (GTK_CONTAINER (window), text);
gtk_widget_show_all (window);
gSuperWindow = gtk_widget_get_window (window);
g_timeout_add (500, press_key, new int {0});
}
int main(int argc, char** argv)
{
GtkApplication* app;
int status;
app = gtk_application_new ("linuxrc.eric", G_APPLICATION_FLAGS_NONE);
g_signal_connect (app, "activate", G_CALLBACK (activate), app);
status = g_application_run (G_APPLICATION (app), argc, argv);
g_object_unref (app);
return status;

Re: clear() on TreeView causes select-events
Dear Reuben,
thanks for your hint.

This works. Disconnecting the "model" from the "view" before doing
clear is the key. But very uncomfortable.
What not worked was to unselect before doing clear. I don't understand
why.
This all sounds to me like a mystic behaviour what could be a bug. But
I am not deep enough into Gtk so I won't open an official report about
this. It is on the core devs and experts in that list to decide if this
is an serious issue or not.
