I am running into a troubling situation and am looking for a little help. My
application re-uses 'tool windows' to display new information. It does so by
removing all children (using a function I wrote to iterate through all
children, destroy them (they iterate their children before destroying
themselves). Then it destroys itself. Then I add the new contents to the
tool window. In FireFox (all versions) I have no problems and the page
renders in the same amount of time every time I bring it up. In IE (all
versions 6-8), it takes longer and longer to render each time I bring up the
tool window (I am using a qx.ui.layout.DockLayout as the main body of the
tool window). And when I say longer, it goes from 2 seconds to 5 seconds to
9 seconds to 15 seconds to 25 seconds etc. It gets out of control very
quickly.
Has anyone come up with a way to manage this or even eliminate the problem?
To me, it looks like the objects are not getting destroyed in memory and
it's causing IE to start choking on them and doesn't release them as it
should.
Here is the function I use to clean out the tool before I add more objects
to it:
disposeChildren:function()
{
try{if(typeof this.hasChildren!='undefined')
{
if(this.hasChildren()==true)
{
this.forEachChild(function(chld)
{
chld.disposeChildren();
chld.setParent(null);
chld.dispose();
qx.ui.core.Widget.flushGlobalQueues();
});
}
}}
catch(e)
{
try{this.setParent(null);
this.dispose();
}
catch(e){}
}
}
Any assistance would be greatly appreciated as we absolutely need to have IE
working somewhat like FireFox. i know it's not going to work as fast, but we
do need it to be consistant.
Thanks,
Jim
