AW: Tree List: changing the $tootip based on the line the mouse is over.

Wed Sep 14 07:46:07 UTC 2022

   Hi Doug
   Yes, only evMouseEnter and evMouseLeave can be triggered. By setting up
   a timer which evaluates the current node of the mouse position I
   thought that it will be possible to change the tooltip. But redrawing
   the tree component with all different options makes no effect. There
   seems no possibility to redraw the tooltip even when changing the
   $tooltipPos. May be some folks out know a solution ?
   So it would be a good enhancement request to Omnis to  provide a
   function for redrawing the current tooltip and 2nd getting an optional
   evMouseMove Event on every component.
   Regards,
   u.

   Betreff: Re: Tree List: changing the $tootip based on the line the
   mouse is over.
   hi Udo.
   long time no talkâ€¦ : (
   thanks for the sample and it has the guts of the answer.   Iâ€™ve been
   playing with it a bit
   I can get what I want and set a tooltip â€” mostly.   When I run my mouse
   up and down the treelist, no other event is generated unltil I move the
   mouse out of the treelist area and back in
   eg the events on the treelist object are
   On evMouseEnter
   # V1007371 see if we can determine what the line is to make a
   customtooltip of the line Calculate line as mouseover(kMLine) Send to
   trace log enter line [line]
   On evMouseLeave
   Calculate line as mouseover(kMLine)
   Send to trace log leave line [line]
   when I move the cursor down the treelist, I expected a trace to look
   like
   enter line 1
   leave line 1
   enter line 2
   leave line 2
   etc
   however, that is not to be.   it only gives an entry in the tracelog
   when you enter the treelist the first time, or move it sideways out of
   the tree list area and then back in
   short of tracking the mouse over the entire window in the main event
   loop and doing a lot of x-y calculations, I think Iâ€™m hooped.   Might
   be time to ask tech support

   this code behind your mouse event.
