I'm looking for a simple way to implement the standard office custom Task pane TabContainer which looks like this one: Standard Office TabContainer
(1) is easy to implement (2) with the TabContainer there is a way to use Icons also - but they don't look so nice like in this one with mouse over effect etc. (3) I didn't found in the standard TabContainer a setting to enable such a line with a marker
Is this a separate component or does anybody has an example what all is needed to have such a control?
