I am exploring a similar requirement that we have.
We are trying to mimic the behaviour found in EXTJS grid component, where we want a popup menu on hovering the mouse over the column header. The menu should consist of options for sorting and locking the column. We also need to position the menu to be placed under the column header. Not sure if there is anything like this out there.
Never tried what you are trying, however, if an event can be triggered from the mouse action, the ToolTip manager allows you to place the tooltip in a specific x/y coordinate. 450/437 are the x,y coordinates.
private function createFO12Tip(event:Event):void
var s:String = "Text string goes here\nNew line here"
fo12Tip = ToolTipManager.createToolTip(s, 450, 437,
null, IUIComponent(event.currentTarget)) as ToolTip;
private function destroyFO12Tip():void
Perhaps using the PopUpManager with a
TitleWindow as the class might do it. You can place all kinds of stuff in the TitleWindow (text, images, links, swfs etc). The only problem is that you have to close the window manually. Sounds like that may be a show-stopper.
