[flexcoders] Viewstack / Navigator Filtering Best Practice?
Hello,
Looking for a little help as far as best practices for filtering a
navigator (togglebuttonbar, buttonbar) from a viewstack data provider.
Each viewstack is a canvas and I only want to present the selection in
the togglebuttonbar IF the XML node which contains the data for the
canvas exists.
Right now I'm using .addChild and .removeChild on the togglebuttonbar
to control which buttons are displayed. That works the firs time the
app loads, but as the user changes the data source (tied to a textbox
that loads a different xml file) it breaks. I'm thinking there is a
way to control which viewstate elements are displayed from within a
dataprovider, but having issues with that.
Right now, this is the XML event result handler source code:
mx:Script
private function XMLDPHandler(event:ResultEvent):void {
pcXMLDP = new XML(event.result);
bbNavigate.removeAllChildren();
if (pcXMLDP.nodename1.length() 0) {
bbNavigate.addChild(vsNavigate .getChildByName(nodename1));
}
else {
bbNavigate.removeChild(vsNavigate .getChildByName(nodename1));
}
/mx:Script
And this is the viewstack / navigator components MXML:
mx:ToggleButtonBar x=10 y=70 id=bbNavigate width=475 /
mx:ViewStack x=10 y=100 id=vsNavigate width=475 height=235
