[Rashid-Malik]

I want to show some information, in a popup box, as the mouse move over each item of a listbox. How may it be done?

Thanks Phillip B…! Help is what is required here.

If the listbox's no. of items are finite & less (say 20), you can store the messages in a string array constant & index it as per the row no. when the mouse is hovered (moved) over the listbox.

I think this should work. Please post back your findings here...

Q1- How do I find out which item the mouse curse is over?

Q2- How do I show the strings in a popup box that changes text dynamically (i.e. requires no input from user)?

Hi,

You can try this,

Get the following properties from te listbox

 - ContentRectPos

 - ContentRectBounds

 - CelHeight

Create a eventloop with listbox: mouseMove

Get position from the mouse by using coords available inside eventloop 

With this information you determine on which item the mouse is over.

and do what ever you want.

Thanks a lot fgrootent! That solved one part of the problem (i.e. how to find out which list item the mouse cursor is over). Now this leaves the second problem. After I have found out which list box item is under the cursor, how do I display text in a tooltip?

As the String I would use the 'tip strip'.

Have a look at the VI package manager (which has a brilliant GUI): They use the tip strip (I guess) to display the full text of an itemin the mult-column-listbox when it's not fully displayed. There was a thread on this forum where one of the main developers shared a lot of tricks. (Can't find it right now).

Thanks F. Schube…! The tip strip property solved the second query.
