ToolTip Class - Visual Basic .NET

Dennis

I have implemented the ToolTip class for a user control that inheirits from
the panel. I show different tool tips depending on where the mouse is on the
control when the hover event occurs. However, if the mouse is moved to
another part of the control, the tooltip doesn't show again until the user
moves the mouse off the control then back on.

How do I reset the tooltip to show again when the mouse moves within the
panel to a different area?

Hi,

Maybe you could set the tootip again in the mouse hover event to
get it to show up

There is an issue with tooltips (tt) not redrawing. I have a form with
several controls and each control has different tt text. To insure that tt
text displays properly as I move the mouse, I handle each control's
MouseEnter event and do
tt.Active=false
tt.Active=true
With this code, all is well - tt's draw and erase as expected. If I comment
it out, mouse move/hover actions yield many cases where the tt is not
redrawn. You can search these newsgroups for tooltip for interesting reading.

In your case, you describe a user control with tt's that depend "on where
the mouse is on the control when the hover event occurs". Does this mean a
control whose MouseEnter event you can handle? If so, try my suggestion. If
not, are you tracking mouse movements yourself? Then as you transition into
an area where a new tooltip should be displayed, toggle tt.active off and on.

Good luck.

Nothing seems to allow me to reset the ToolTip until the mouse moves off the
control then back on. Another Inferior control from M'Soft!

ToolTip.Show(..), where?

by: Lucian Wischik | last post by:

I'm using ToolTip.Show(x,y,..) to show my balloon-style tooltip at a specified coordinate. Most of the time it works fine and the "tip" of the balloon points exactly to my specified (x,y) coordinates. But if the (x,y) coordinates are too far to the right, then the "tip" of the balloon now points to some spurious coordinate that's unrelated to my (x,y). Why? How can I stop this? How can I make the balloon's tip point exactly where I...
