On a gtkd drawingarea I want to capture the mouse-pressed event and get the coordinates of the pointer on the area.
I have

addEvents(GdkEventMask.BUTTON_PRESS_MASK);

Maybe I must add a signal-handler ?

Not a gtk user, but maybe this will help (has quite a list of examples on gtkd, newest first)

I'll have a look at that website.
With this code I capture the mouse press event

this()
{
addEvents(GdkEventMask.BUTTON_PRESS_MASK);
addOnDraw(&drawCallback);
addOnButtonPress(&onButtonPress);
}


public bool onButtonPress(Event event, Widget widget)
{
writeln("Button pressed");
return false;
}

But I still need the coordinates of pointer.

I'm not gtk user too but you could try to use GdkEventMask.BUTTON_MOTION_MASK to get pointer
motion events while some button is pressed
