I need to update an TImage->Hint very quickily at the mouse move... It's something like using the hint to display X and Y mouse coordinates in the Image Box. Is there any HintUpdateFrequency property to set anywhere? Thanks Andrea Back to top Bono Guest Posted: Thu Mar 16, 2006 3:03 pm    Post subject: Re: Hint refresh frequency Of course, it is. If I place a breakpoint on the "box->Hint =....", I can see the hint value changing, but the display on the Image is not updated. ??

If I use Application->HintPause I only see the first Hint faster. But the hint text doesn't update when I move the mouse... What's wrong?? Please can you show the code that sets the hint text. It should update automatically.

Set the TImage's ShowHint property to false, and then display your own instance of the THintWindow class directly. You can intercept the CM_MOUSEENTER message to create the THintWindow, intercept the CM_MOUSELEAVE message to destroy it, and the OnMouseMove event to move it around.
