There is no way I know to hide the mouse from inside LabVIEW, Which means that you'll have to do something a little odd. You could just programatically position the mouse off of the screen. On a windows system you would have to do this by calling a Windows API, in Linux I guess there's probably something you can do through the Desktop Environment or Xwindows.

How to hide the cursor in LabVIEW 6.1 under XFree86 4.3.0. I can hide the cursor in the root window of XFree86 (desktop) but as soon as I start LabVIEW the cursor becomes visable. I think LabVIEW defines it's own cursor. Is there a possibility to define a empty bitmap for LabVIEW's cursors?

Hi,

In Windows LV defines it's own cursors. So in Windows, if you set a cursor,
LV used to overwrite this (I know this for LV6), as soon as you move the
mouse.

In LV7, there are VI's to change the cursor in Windows, I don't know if LV
for Linux has them too...

Hope it helps,

Wiebe.

They should work on all desktop machines that support LV. If you find
problems, please report them.

Thank you for your replies.

We have an embedded application with touch screen. The application is designed with LV5.1 and runs under WindowsNT.
Currently we are porting the application to Linux. We want to hide the cursor, just like we did for WindowsNT.

Is it also possible to change the cursor under LV5.1? Or is there another way to make the cursor invisible.

Thanks in advance,

I exhausted every resource I could find, and came up with only one answer: unclutter

It is a small utility that will hide the mouse cursor after a small period of inactivity. It will not work on the root window, however. Also, it is probably not ideal for a touchscreen since the cursor will reappear with any movement/buttonclicks. In the case of my "embedded" app, the mouse is never used.

Hope this helps.
