Keypress events

[Guenther Sohler <guenther sohler newlogic com>]

Hallo,

I am a newbie to gtk

I have got a DrawingArea and I want to receive key events and mouse click
events.
Therefore I set mask by
gtk_widget_set_events( widget,GDK_KEY_PRESS_MASK|GDK_BUTTON_PRESS_MASK);

I additionally set a callback 
with 
gtk_signal_connect ( GTK_OBJECT (widget), "key_press_event",GTK_SIGNAL_FUNC
(key_pressed_cb),  NULL);
gtk_signal_connect ( GTK_OBJECT (widget),
"button_press_event",GTK_SIGNAL_FUNC
(button_pressed_cb),  NULL);

I set the mask on the drawingarea widget immediately after creating. so its not
displayed as stated in the documentation.

Mouse PRess events work properly, but key events won't and I dont have an idea
why

can anybody help me ?

Maybe anybody can also answer me these quiestions by heard.

How can I determine the actual/current dimensions x/y of my drawing area ?

I have found the function gdk_draw_line to draw a black line.


How can I draw a filled colored triangle ?
