Hi,
I have a question about using Tooltips in flex 3.
When I have set the tooltip-property of a UIComponent to a string, I
can
set the porperty ToolTipManager.toolTipClass to any custom class I
want to.
If I use the ToolTipManager.createToolTip-method to create the Tooltip
manually, I don't have the possibility to use a custom class. Setting
the toolTipClass has no effect. I checked the
mx.managers.ToolTipManagerImpl-class and found out, that in the
createToolTip-method always the standard ToolTip-class is used.
Is there any other solution to get custom classes working, than
patching
the ToolTipManagerImpl-class?
Thanks
John
I think that if you go as deep as patching the Impl classes of any
framework, there's something wrong.
There's a simpler way to do that.
Your component should do:
myComponent
.addEventListener(ToolTipEvent.TOOL_TIP_CREATE,tooltipDetailCreate);
myComponent.toolTip = " ";
then you should do something like...
private function tooltipDetailCreate(event:ToolTipEvent):void {
var tt:PieChartToolTip = new PieChartToolTip();
tt.width = 390;
tt.height = 180;
tt.dataProvider = // whatever data provider or property you need
to set for your tooltip component
tt.headerText = "My tooltip header"
event.toolTip = tt;
}
In our case our component is a some king of gauge which shows some
progression and its tooltip is a PieChart which shows the repartition
of the data from the progression.
That way, whenever a tooltip event is fired it will display your
component.
Good luck,
