I've got a dataGrid, but am using VBox's that implement IToolTip to generate my toolTips instead of relying on the built-in dataTip functionality. Every thing works fine until it comes to positioning the toolTips along the bottom right of the dataGrid, as the default behavior isn't re-positioning the toolTip correctly and I'm seeing most of the toolTip disappearing off the screen.
My toolTip is just a simple VBox with a simple mx:Text component, and I set the text property of the mx:Text component. It can be of varying length, and it doesn't appear that the height/width of the rendered VBox is being pushed up to the toolTip itself as the event.toolTip.width and height are 0 after I create the toolTip. any ideas? I'm capturing the toolTipCreate event from my DataGridColumn renderers (simple labels), creating a toolTip from a component that implements IToolTip, and then using that resulting toolTip instance to set the event.toolTip property. var customToolTip:DataGridDropDeadSequenceToolTipRenderer = new DataGridDropDeadSequenceToolTipRenderer(); event.toolTip=customToolTip;
