Hi,
I would like to be able to click on a Drawing area and extract
the cursors position, and possibly drag-select over its suface.
Are there any tutorials on this?
I have connected a function to the button release on the Drawing
Area (see below), this does not seem to trigger the function call,
gtk_signal_connect (GTK_OBJECT (guiDrawingArea), "button_press_event",
GTK_SIGNAL_FUNC (on_guiDrawingArea_button_press_event),
NULL);
But even if I managed to get the function call to execute, from where do
I extract the cursor's location..
I look forward to your collective wisdom..
Many thanks in advance..
Colin Thomas.
