mouseTrack() function Any one use it?

[Moosley]

I've used it in a couple of scripts... What sort of trouble are you having?

[PEN]

Do you have any example code on how to use the call back function? I just can't get the syntax right. It isn't doing a thing.

Hey Paul,

I haven't used the mouseTrack() function specifically but I did use mouse tracking in this script....it might be helpful to look at

[PEN]

Thanks. I have used all the other mouse tracking tools before just never mouseTrack().

I think this way works, although #mouseAbout doesn't seem to work... (press ESC to exit tracking)



fn MyCallbackFn msg ir obj faceNum shift ctrl alt =
(
myStr = "Pos ("+mouse.pos.x as string +", "+ mouse.pos.y as string + ")"

case msg of
(
#freeMove: myStr += " [freeMove]"
#mousePoint: myStr += " [left click]"
#mouseMove: myStr += " [left drag]"
#mouseabout: myStr += " [righ click]"
)

print myStr
#continue
)

mouseTrack trackCallback:MyCallbackFn



hope this helps

cyberluigi2k's code is right except that it's #mouseAbort instead of #mouseAbout.
You can also get it to track on a specific object using the ' on:<node> ' option in the call.

I've used the mousetrack function before but if I remember correctly it doesn't allow any viewport operations (panning/zooming). That's why I prefer mouse tools.

Mouse tools doesn't allow of it either that is why I'm looking at other methods

Oops!! Sorry Paul... I thought I was replying to your message but I accidentally pressed the Edit button instead and removed most part of your post.. :blush:

You can rotate and pan/zoom with mousetrack via the middle mouse button. Just not with the viewport control buttons (which change the focus of the cursor).

Interesting, mouseTools doesn't allow for that at all. I still think that I will script my own solution so that I don't have to start and stop the tool. MouseTrack disables the rest of the keyboard from working though so you can't change from say right to front viewport.

LOL!! it seems so obvious... i was thinking why on earth they choose mouseabout for the right button.... anyway in my deffense i can say that i took it from the documentation... you can read at "mouseTrack() Function" topic


The 'msg' argument is a message code that indicates what kind of action occurred, and can be one of:

#freeMove - means the mouse is moved without a button being pressed

#mousePoint - means the left mouse button has just been pressed

#mouseMove - means the mouse is being dragged with the left button down

#mouseAbout- means the right mouse button was clicked, normally meaning cancel

[Moosley]

Oh yeah! Never noticed that, always 'misread' it to be 'Abort ' :)

I mixed up the two functions.. I use mouseTrack only instead of tools because mouseTrack does indeed allow viewport manipulations. :)
