Re: Applying a TextTag on newly-written Text

[Armin Burgmeier <armin arbur net>]

Hi once again,

well, thats quite exactly what I am doing, and it does not show up the
applied tag immediately. I wrote a small application that shows up just
a text view that colors incoming text, to ensure that noting else in my
application causes the problem, but the behavior did not change.

I attached this small piece of code to this mail, maybe you can find out
what's wrong, maybe it works for you, maybe you cannot, but I thank you
for you effort anyways.

#include <gtkmm/textview.h>
#include <gtkmm/scrolledwindow.h>
#include <gtkmm/window.h>
#include <gtkmm/main.h>

class MyView : public Gtk::TextView
{
public:
	MyView()
	{
		Glib::RefPtr<Gtk::TextTag> tag =
			get_buffer()->create_tag("orange");
		tag->property_background() = "orange";

		add_events(Gdk::KEY_PRESS_MASK);
	}

protected:
	virtual bool on_key_press_event(GdkEventKey* event)
	{
		Gtk::TextView::on_key_press_event(event);
		get_buffer()->remove_all_tags(get_buffer()->begin(), get_buffer()->end() );
		get_buffer()->apply_tag_by_name("orange", get_buffer()->begin(), get_buffer()->end() );
		return true;
	}
};

int main(int argc, char* argv[])
{
	Gtk::Main kit(argc, argv);

	MyView view;
	Gtk::ScrolledWindow wnd;
	Gtk::Window mainw;

	wnd.add(view);
	mainw.add(wnd);

	mainw.show_all();
	Gtk::Main::run(mainw);
	return 0;
}
