Re: Not getting which mouse button is pressed on button-press-event
Many thanks Tadej! event->button works fine. Here is trace info for left, right and simulated mid buttons: mousebuttonDOWN (x,y)=(10,14)state 0 btn=1 mousebuttonUP (x,y)=(10,14)state 100 button=1 mousebuttonDOWN (x,y)=(9,14)state 0 btn=3 mousebuttonUP (x,y)=(9,14)state 400 button=3 mousebuttonDOWN (x,y)=(9,14)state 0 btn=2 mousebuttonUP (x,y)=(9,14)state 200 button=3 mousebuttonUP (x,y)=(9,14)state 200 button=2 It shows state is not set on any ButtonDown event, ButtonUP works for left and right button but not for simulated mid button (should only be one UP event for button 2). Should this behaviour be considered a bug? --- On Thu, 14/1/10, Tadej Borovšak wrote: From: Tadej Borovšak Subject: Re: Not getting which mouse button is pressed on button-press-event To: "Ken Resander" Cc: gtk-list@gnome.org Date: Thursday, 14 January, 2010, 3:13 AM Hello. You can get the mouse button pressed by looking at event->button field. 1 means left button, 2 middle button (which can usually be emulated by pressing right and left button at once on 2-button mouse), 3 right button.

Re: Not getting which mouse button is pressed on button-press-event
Robert, You are right - I've been buried for days in X Windows code (not GTK+) and my mindset was in the wrong place for this list. My bad.

That's an X setting - EmulateMiddleButton or something of the like. If it's set then X intercepts near-simultaneous left and right buttons and substitutes a middle button. > Can't verify 6,7, but perhaps it's time for me to buy a better > mouse.

You get some flexibility on what you map them to, and it's possible to use them for scrolling instead of 4 and 5. But as I understand it, none of this is relevant to GTK, which just passes through what the back-end produces.

Re: Not getting which mouse button is pressed on button-press-event
Just tried it and verified most of the answer, via something I'm playing with;
UINT ejEventManager::getButton () {
return currEvent.xbutton.button;
}
1 == Left mouse button
2 == Right mouse button
4 == scroll up
5 == scroll down
Wasn't able to emulate middle button on my 2-button mouse (project for another
day, perhaps). Can't verify 6,7, but perhaps it's time for me to buy a better
mouse. I wonder, though, if this might be useful with a joystick (left, right).

Not getting which mouse button is pressed on button-press-event
The state member in GdkEventButton for the button-press/release events contains
flag bits that specify which mouse button is operated and also any keyboard
shift/ctrl/alt modifier bits. I have tried button-press-event on several widget
types, but in all cases the modifier bit GDK_BUTTON1_MASK or GDK_BUTTON2_MASK
is not set on button-press. It is however set in the button-release-event.
If a mouse button is held down while pressing keys the state in GdkEventKey
shows the correct GDK_BUTTON1_MASK or GDK_BUTTON2_MASK.
I need to know the mouse button pressed on button-press.
The program below shows this for a top window widget.
static gboolean buttonpresscallback ( GtkWidget * w,
GdkEventButton * event,
char * data )
{
printf ( " mousebuttonDOWN (x,y)=(%d,%d)state %x\n" ,
(int)event->x , (int)event->y , event->state ) ;
return false;
}
static gboolean buttonreleasecallback ( GtkWidget * w,
GdkEventButton * event,
char * data )
{
printf ( " mousebuttonUP (x,y)=(%d,%d)state %x\n" ,
(int)event->x , (int)event->y , event->state ) ;
return false;
}
static gboolean keypresscallback ( GtkWidget * w,
GdkEventKey *event,
char * data )
{
printf ( " key PRESS val=%x state=%x\n" , event->keyval , event->state ) ;
return false;
}
static gboolean keyreleasecallback ( GtkWidget *eventbox,
GdkEventKey *event,
char * data )
{
printf ( " key RELEASE val=%x state=%x\n" , event->keyval , event->state ) ;
return false;
}
int main ( int argc , char * argv[] )
{
gtk_init(&argc, &argv);
GtkWidget * window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
gtk_window_set_default_size(GTK_WINDOW(window), 250, 180);
gtk_window_set_title(GTK_WINDOW(window), "Testing");
gtk_widget_add_events (window , GDK_BUTTON_PRESS_MASK );
g_signal_connect (window, "button-press-event",
G_CALLBACK (buttonpresscallback), NULL ) ;
gtk_widget_add_events (window, GDK_BUTTON_RELEASE_MASK );
g_signal_connect (window, "button-release-event",
G_CALLBACK (buttonreleasecallback), NULL ) ;
gtk_widget_add_events (window, GDK_KEY_PRESS_MASK );
g_signal_connect ( window, "key-press-event",
G_CALLBACK (keypresscallback), NULL ) ;
gtk_widget_add_events (window, GDK_KEY_RELEASE_MASK );
g_signal_connect ( window, "key-release-event",
G_CALLBACK (keyreleasecallback), NULL ) ;
g_signal_connect(window, "destroy",
G_CALLBACK (gtk_main_quit), NULL);
gtk_widget_show_all(window);
gtk_main();
return 0;
}
Am I doing something wrong?
I have a two-button mouse and observed that the right-mouse corresponds to
GDK_BUTTON3_MASK, not GDK_BUTTON2_MASK that I expected. However, when I
mistakenly pressed left and right button together I received the result
GDK_BUTTON2 on button-release. Is this the way it is? What about bit mask and
button correspondence for a 5-button mouse (if such animal exists in the real
world)?
