Hello all.

I have made a textview placed in a scrolled window, but i am having troubles replacing the two scroll bars with buttons (up-down, right-left).

I have used the function call:

Code: (Plaintext)
1 2	gtk_scrolled_window_set_policy(GTK_SCROLLED_WINDOW(scrolled_win), GTK_POLICY_NEVER, GTK_POLICY_NEVER);

This allows me to implement buttons instead of scroll bars...

The callback function for f.x the down button I implemented as:

Code: (Plaintext)
1 2 3 4 5 6 7 8 9 10 11 12	void FulldownClicked(GtkWidget widget, gpointer data) { GtkAdjustment adj; gint value; adj = gtk_scrolled_window_get_vadjustment(GTK_SCROLLED_WINDOW( fullstruct.scrolled_win)); value = gtk_adjustment_get_value(adj); gtk_adjustment_set_value(adj, value-22); gtk_adjustment_value_changed( adj ); }

but it dosent work, how do I replace the scrol bars with buttons?

Thanks for the advice dreblen.

I ended up with:

Code: (Plaintext)

scrolled_win = gtk_scrolled_window_new(NULL, NULL);
gtk_scrolled_window_set_policy(GTK_SCROLLED_WINDOW(scrolled_win),
GTK_POLICY_NEVER, GTK_POLICY_NEVER);

horizontal = gtk_scrolled_window_get_hadjustment(
GTK_SCROLLED_WINDOW(scrolled_win));
vertical = gtk_scrolled_window_get_vadjustment(
GTK_SCROLLED_WINDOW(scrolled_win));

viewport = gtk_viewport_new(horizontal, vertical);
gtk_container_add(GTK_CONTAINER(scrolled_win), viewport);
gtk_container_add(GTK_CONTAINER(viewport), textview);

This allows me to make adjustments to the GtkAdjustment widget in my button callback function.
