Re: Ctrl-Click keyboard mouse event

Hi Emmanuel,
thank you very much, that's exactly what I needed,

Best regards,
Carlos


When a button press event is triggered, what is the proper way to know if
the user is pressing down the Ctrl key?



I think that this is what you need:

if (event->button == 1 && (event->state & GDK_CONTROL_MASK) != 0)
{
  /* Button 1 with contro clicked */
}

I think that this is what you need:

if (event->button == 1 && (event->state & GDK_CONTROL_MASK) != 0)
{
  /* Button 1 with contro clicked */
}

Ctrl-Click keyboard mouse event

2009-11-10 Thread Carlos Pereira 

Hi list,
When a button press event is triggered, what is the proper way to know 
if the user is pressing down the Ctrl key?


Tipically I would want to know this inside a button press event callback:

int handle_button_press (GtkWidget *widget,
GdkEventButton *event, void *data)
{
mouse button has been clicked: is Ctrl key down???
...
}

(I need this to implement multiple selections from my OpenGL code that 
are consistent with multiple selections in GtkTreeView)


Thanks,
Carlos
