Title: ParentNotify not working for sub-window
Post by: anarchist on January 12, 2014, 05:55:14 PM

Hello all,

Not certain whether this is expected behaviour or if I am doing something wrong. I have a window which contains a nested window. The nested window contains a button named "btnOption1". Both the button and the nested window have ParentNotify = true.

Indide the parent window's script I have added:

Code: WME Script

1. on "btnOption1"
2. {
3.         //do something
4. }
5.  

I am expecting this to be called when I press the button inside the nested window. Unfortunately, this is not the case. I set a breakpoint here (I have some code, not comments) and it is never reached.

I have moved the button inside the parent window and the above code is reached. Therefore, something is wrong with the nested window. Do I need to add a script to catch the button press event?

I am working with WME Project Manager 1.10.001 which is still in beta, so I am not sure if this is a bug.

Yes, in the main window script you need to define some method, for example:
   

Code: WME Script

1.     on "NestedButton"
2.     {
3.             //do something
4.     }

     
And in the nested window script:

Code: WME Script

1.     on "btnOption1"
2.     {
3.             var Window = this.Parent;
4.             Window.ApplyEvent("NestedButton");
5.     }

Thanks 2.0, that is exactly the information I needed.

A more general question that rises from this is: Since the nested window does not send the events to the parent, what is the use of ParentNotify?

It works for buttons within the window at least. As about windows - well, every day is not Sunday :)

Parent of the button is window, not a parent window.

Parent of the button is window, not a parent window.

I understand that, but shouldn't the parent window be notified with event "btnOption1" when button triggers that event in the sub-window (provided that the sub-window does not handle the particular event in its script)?

btnOption1 clicked -> nested window event btnOption1 triggers -> nested window does not handle event -> parent window event btnOption1 triggers

Is the above logic flawed?

What you're saying makes sense, but ParentNotify only seems to work for buttons as far as I can tell, so you can't chain it like that. 2.0's answer is the best way to go.
