digitalmars.D.learn - gtkD: events being triggered twice

reply Johnson Jones <JJ Dynomite.com> writes:
GtkEventBox - Enter
GtkEventBox - Enter
Down
GtkEventBox - Leave
Up
GtkEventBox - Leave
GtkEventBox - Leave

That is when I move the mouse over the event box then click then 
move out out then release.

I would expect

Enter Down Leave Up

The fact that enter and leave are not paired equally is a 
problem. Can be worked around but seems like it would be a bug.

the code is simply


ebox.addOnEnterNotify(delegate(Event e, Widget w)
{	
writeln(w.getName(), " - ", "Enter");
return true;									});

ebox.addOnLeaveNotify((Event e, Widget w)
{									writeln(w.getName(), " - ", "Leave");
return true;
});

Do you have an more complete example that i could test.

I don't really(my code is a bit more complex) but basically all 
it boils down to is a UI with some nested widgets (an overlay, an 
box, and a box and one contains the eventbox which I added those 
callbacks on.

I think that something like

https://github.com/gtkd-developers/GtkD/blob/master/demos/gtkD/TestWindow/TestWindow.d

should probably work by just adding an eventbox somewhere and 
adding that code above.

If it doesn't exhibit the same behavior then it has something to 
do with my project and I could try to reduce it to a minimal 
example.

To test i put the label that is on the label page in an event box but 
that doesn't reproduce the issue. I get just a single event on enter and 
a single event on leave.

Ok, I will try to work on figuring out what is going and and 
potentially reduce to a test case. It might be on my end. I'm 
pretty sure I'm not adding

You might try a separator though in the event box and might try 
to add it handling various events(maybe even other events for the 
event box)... things related to the mouse.

Here's the glade code for the event box I'm using

               <object class="GtkEventBox" id="MainSeparator">
                 <property name="height_request">5</property>
                 <property name="visible">True</property>
                 <property name="can_focus">False</property>
                 <property name="above_child">True</property>
                 <child>
                   <object class="GtkSeparator">
                     <property name="height_request">5</property>
                     <property name="visible">True</property>
                     <property name="sensitive">False</property>
                     <property name="can_focus">False</property>
                     <property name="events"/>
                     <property 
name="orientation">vertical</property>
                   </object>
                 </child>
               </object>


Try that when you get some time and see if that changes anything. 
If it doesn't then it's surely in my code or in the gtk version 
I'm using(still using msys, I'll update to what you released to 
see if that fixes it). At least we can narrow it down a little...

I don't know gtk, but I would suspect moving the mouse over the 
child triggers the enter/leave notifications too and it bubbles 
up to the parent.

Yeah, but both those events are from EventBox. If that were true 
I'd except Separator to be shown as the widget that has the 
event. I do return true from the handler which I believe is 
suppose to stop any more handlers.

Although, it does sound something like what you are saying... but 
it also doesn't explain why the events are not paired, which is 
the more serious issue.

Also seems to be working properly with a Separator.

Ok, I guess it's on my end, I don't see how since I'm not doing a 
hell of a lot and only gtk is calling those event handlers, I'll 
try to create a test app at some point. I've already added logic 
to prevent multiple reentries though so, for now I've solved the 
problem.
