updating tooltip text without moving the mouse
hello,
how do i update/refresh the tooltip with new text, without waiting for the mouse to be moved (and without using Robot to move the mouse). i've attached sample code at the bottom which exhibits some unexpected behavior.
if you move your mouse over the second button and hit any key, then the tooltip text is changed, but does not get updated on the screen until the mouse is moved. this is causing problems with a 3rd party charting bean that uses tooltips to display some labels.
any thoughts? thanks,
raj
