Hello Sir, Here comes my questions.I have 4 to 5 layers of panels in the layered pane.I have a first optional panel which has a button.If the button is pressed (it sets to ok icon). If ok is set then the tooltiptext for the components in all the panels added to the layered pane should be set. If same button is clicked twice (it is set to no icon) & the tooltiptext should not be set. How is it possible to make tooltiptext null.Give me some idea regarding this how to start. Hope to get reply from u soon. With regards, Sonara.
