LayoutManager destroy function?

Posted in xn--kfs74mzzid01b.com edit by wktd on January 7th, 2009

I am constantly removing / creating NestedLayoutPanel's which contain Grids, other NestedLayoutPanels, etc. Should I be worried about leaks since there is no destroy method that gets called on the Layouts, Regions and each Panel when I remove a parent NestedLayoutPanel (at least none I could find)?

Hi matjaz,
looking for exact this feature I read this thread and tried out your code! Unluckely I cannot get it to work. Perhaps there is s.th. wrong with my call:

innerLayout.destroy();Following the usual samples innerLayout is the nested BorderLayout .

I call your code from .js -file after loading ext stuff. (1.1)

Firebug error :
this.el has no properties

Thanks for any help in advance.

I was questioning the same thing.
I have nested layout with many content panels across regions.
I implemented my own destroy() methods something like: destroy: function()
{
delete this.panel;
abc.FilterPanel.superclass.destroy.call(this);
}

I used kalebwalton's (whose code is incorrect) idea of implementing this:Ext.override(Ext.LayoutManager, {
destroy: function()
{
for (var region in this.regions) {
var r = this.regions[region];
for (var i=0, len=r.panels.length; i r.panels.itemAt(i).destroy();
}
}
}
});

Ext.override(Ext.NestedLayoutPanel, {
destroy: function()
{
this.layout.destroy();
Ext.NestedLayoutPanel.superclass.destroy.call(this );
}
});And now contentpanel's destroy() gets called.
Shouldn't Ext support this ?

FYI - I'm just going to do something like the following for the time being:

/**
* Destroys each Panel in all the BorderLayouts LayoutRegions
*/
Ext.BorderLayout.prototype.destroy = function() {
for(var region in this.regions) {
for (var i=0,len=region.panels ? region.panels.length : 0;i region.panels[i].destroy();
}
}
};

/**
* Destroys the BorderLayout in the NestedLayoutPanel
*/
Ext.NestedLayoutPanel.prototype.destroy = function() {
this.layout.destroy();
Ext.NestedLayoutPanel.superclass.destroy.call(this )
};
