Mouseover in Labview

Is it possible to do a mouseover type function in Labview where when the
mouse is over a button that a certain picture can be displayed. Thanks.

I dont think you can do a picture, but in LV 6i you can display text
like when you mouseover the items in the tool bar.

Right click the control and you will see the menu item.

Dewayne,

I use the picture control when I want a mouseover effect. The control has
a mouse attribute that you can monitor in a while loop, when the attribute
= -1 the mouse isn't over the control, so you can wire your original picture.
when it isn't = -1 (mouse is over control) you can wire new picture. there
is also a 'button down' attribute, so when mouse is clicked you can call
other vi, etc. as well as display a third image if you want one for when
button is clicked. one suggestion, read images first to avoid delays.

I have done similar and was about to post it, but saw yours first..

In my experience this EATS through processor time. Any picture indicator
displays or probes tend to be very very slow in my experience. I'd love to
know how to speed these things up somehow. Not sure if I'm simply
experiencing slow communication with video drivers/hardware etc, but I tend
to have a couple hundred MS latency writing to the indicators and under a
hundred trying to read the attribute nodes.

Hi Dewayne

There is a mouse library in the info-labview ftp site.

ftp://labview.pica.army.mil/pub/labview/vi/lv4/

the file name is:

mouse13.zip and mouse13.txt

Hi Again

I have just read my reply to Dewayne and thought it a bit brief.

The files mouse13.zip contains an excellent vi called mouse magic. It is a small file that uses a DLL to return the mouse
position, relative to the screen, and which mouse button pressed.
To make the absolute mouse position relative to its position in the window you have to use vi server to find the window's origin
and bounds. To know if the mouse is over a control you have to check the mouse position to see if its relative position is over
the control area. The control area is is found using the controls origin and bounds attributes.

Hope this is more helpful

Tim

p.s. sorry about the repeated message.

Yes.

You can get the bounds of an object via an attribute node, and the mouse
coords from freely available vi's.

OR

Place a picture control behind the button and return the attribute node
property called MOUSE. It returns the coordinates of the mouse relative to
the control ((0,0) ... (x,y)) and (-1,-1) if outside the picture.
