Re: Tooltips and MouseMove event

MouseHover() won't do it.  It only fires once for the _canvas.  Looks
like I have to use the MouseMove() event.  I'm surprised at the number
of times this event fires before it seems to 'settle down'.

Subject: [DOTNET-CX] Tooltips and MouseMove event

I am drawing an array of circles, boxes, etc., on a graphics object
associated with a panel control.  The class I use to do this is called
'Cartridge'.  So one of the items in the constructor of the Cartridge
object is a panel control (though technically it could be any control to
which I can get a reference to a graphics object) I am referring to as
_canvas.

Anyway, I have realized that it would be very beneficial to provide
tooltips when the mouse hovers over some of the shapes I have drawn.  To
try to implement this, I have created a ToolTip object in the Cartridge
class and have attempted to set it in two places - first, an event
handler connected to the _canvas.MouseMove() event; second, in an event
handler connected to the _canvas.MouseHover() event.  Neither produces
the desired effect.

The MouseMove() event seems to fire at intervals of about 500 ms
regardless of whether or not I am moving the Mouse over the _canvas.
The MouseHover() event never (very, very seldom) seems to fire.

Any suggestions on what I can do to implement this tooltip
functionality?
