Found this post, but I imagine that this applies to Flex 1.5. I'd like to create a custom toolTip in Flex 2.0 that would behave like a toolTip, but would be able to take a dataObject as a parameter and would have some formatting. I don't this this is possible w/ the toolTip styles available in Flex
2.0 (beta 2), as these styles relate across the entire toolTip. In any case, is there a new way to "hijack" the toolTip class and substitute a custom one on a per-component basis?
Thanks,
Jaime

Yes this is possible, basically what happens is that every component
inside FLEX that extends UIObject has a property called "toolTipClass"
(string) which it uses in order to present a tool tip upon such
attribute being provided for that said component (pant)
eg:
<mx:Button label="blah" toolTip="blah"/>
Now, if you wanted to extend or customize the tooltip this can be done
in one of two ways:
1) You can hijack the actual toolTip class and swap it for your own via
<mx:Application>
<mx:Script>
import com.mossyblog.controls.ToolTip;
</mx:Script>
<!-- your typical app here -->
</mx:Application>
class com.mossyblog.controls.ToolTip extends mx.controls.ToolTip
{
static var symbolName:String = "mx.controls.ToolTip";
static var symbolOwner:Object = com.mossyblog.controls.ToolTip;
// Begin your logic here..
}
** NOTE: What's happening here is you are basically hijacking the
symbolName "mx.controls.ToolTip" and making such name point to your
custom built class, allowing you to effectively use the same tooltip
FLEX-APP-WIDE without having to touch existing code.
I've used the same approach for Tabs/TitleBackground and works well imho.
2) Extend the class in which you want to use yoru custom ToolTip only
with, and put the following:
class com.mossyblog.controls.Button extends mx.controls.Button {
var toolTipClass:String = "com.mossyblog.controls.ToolTip ";
}
** NOTE: Again, same concept except your telling the "Button" to use a
custom ToolTip and not the default one (again making sure in your
"custom ToolTipClass" you set the static var symbolName:String =
"com.mossyblog.controls.ToolTip"
As for what you do with the toolTip? well anything you like. You could
put an mx:Panel inside your toolTip if you wanted to etc..but i'd
execute extreme caution with this, as this could be a dangerous point
in which performance may decrease as a result of a complex ToolTip.
