is there a mouse roll event?

[mitulatbati]

Hi all,

I want to roll a Multicolumn listbox with the mouse roller. The best would be an event case, because I use an event structure.

I can´t solve it with the mouse related events, so is there any possibility to make it?

NO. There is no Mouse Roll event for the Multicolumn Listbox even in LV 8.5.

Why do you need it ? What re you trying to achieve with it ?

Can you be a bit elaborate ?

What is your LV version ?

Hi,

Well, I have a monitor resolution of 1024 x 768, and a multicolumn listbox with more than 100 rows. It is no problem to scroll with the scrollbar, but it would be more confortable to roll with the mouse. It´s clear, that there is no roll mouse event, but isn´t there any tricky solution to solve this? How can I process the mouse roller activities at all?

A search can do some wonders:

tst,

That link of Jonnie's says "Page not found"...

Can you please post the Vi, if you ve ?

I was thinking more of reply 12.

Also, I'm sure you can get to Hamilton's site through Google.

The key is the Acquire input data.vi, which has an "axis" output cluster with a "scrolling" element.

I have to monitor this, and when the value is negativ => a scroll down happened, when positiv=> scroll up happened.

Another cool thing is that starting in LabVIEW 8.0 (I think), listboxes, tables, and tree controls scroll automatically with the mouse scroll wheel...no code required.

Wait, in labview 8.2 a mouse roll will scroll a multicolumn listbox automatically already.  There is no event generated, but the listbox scrolls fine.

Isn't that what I just said?  😉  This behavior was added in LabVIEW 8.0.
