SOLVED: Window beforehide problem

[JeffBurr]

I have an issue with a Window. I am trying to intercept the hide event. This works as hoped:

win.on('beforehide', function() {
  if(confirm("Are you sure?"))
    return true;
  else
    return false;
});

And stops the hide event. But I would like to do this:

win.on('beforehide', function() {
  Ext.MessageBox.confirm('Close', 'You may have unsaved changes. Continue?', 
    function(btn) {
       if(btn=='yes') return true;
       else return false;
  });
});

And it does not work (always continues with the hide).

I suspect this is because the MessageBox has its own hide event and the win gets confused. Is there a way to workaround?
Thanks!

It's because the MessageBox doesn't wait for a response.

Try this:

Ext.Window.prototype.forceHide = function(animateTarget)
{
   this.hidden = true;
   if (animateTarget !== undefined)
      this.setAnimateTarget(animateTarget);

   if (!this.animateTarget)
   {
      this.el.hide();
      this.afterHide();
   }
   else
      this.animHide();
};

win.on('beforehide', function()
{
   Ext.MessageBox.confirm('Close', 'You may have unsaved changes. Continue?', 
    function(btn) {
       if(btn=='yes') win.forceHide();
  });
   return false; //always return false to wait for the response.
}
);

I didn't intend to submit this as a "bug". I guess I shouldn't drink and post!

Anyway, thanks for the solution - works perfectly.

Found this today and it works great.

However, I am using modal windows, so in the event that anyone else is, you just need to add the following to the forceHide function. Otherwise the page stays masked, even though the window is closed.

if(this.modal){
  this.mask.hide();
  Ext.getBody().removeClass('x-body-masked');
}

Thanks,

Easier is

win.on('beforehide', function() {
   Ext.MessageBox.confirm('Close', 'You may have unsaved changes. Continue?', 
    function(btn) {
       if(btn=='yes') {
         win.suspendEvents();
         win.hide();  // This cannot be vetoed because no events will be fired.
         win.resumeEvents();
       }
  });
  return false; //always return false to veto the hide.
});
