Hey Nick,
You could assign a name to your tab and then use
this.windowTabs.getChildByName(newtab.name);
Something like
private function createTab(createTabName:String):void
{
var newid:String = 'userTab' +
this.masterList.selectedItem.ContribNum;
var selectTab:Container = this.windowTabs.getChildByName(newid);
if(!selectTab) {
var newVbox:VBox = new VBox();
var newHbox:HBox = new HBox();
var newTab:Canvas = new Canvas();
var newSpacer:Spacer = new Spacer();
var tabCloseBtn:Button = new Button();
// create button to close tab
tabCloseBtn.label = "Close Tab";
tabCloseBtn.addEventListener
(MouseEvent.CLICK,myClickListener);
// create spacer to position close button
newSpacer.percentWidth = 100;
// create box layout controls
newHbox.percentWidth = 100;
newHbox.addChild(newSpacer);
newHbox.addChild(tabCloseBtn);
newVbox.addChild(newHbox);
newVbox.addChild
(getTithesComponent(this.masterList.selectedItem.ContribNum));
// create tab
newTab.label = createTabName;
newTab.id = newid;
newTab.name = newid;
newTab.addChild(newVbox);
this.windowTabs.addChild(newTab);
this.windowTabs.selectedChild = newTab;
}
else
this.windowTabs.selectedChild = selectTab;
}
