Re: [osg-users] Hide mouse pointer and set mouse pointer position

2009-05-14 Thread Robert Osfield 
Hi Paul,

A couple of pointers

You can use GraphicsWindow::useCursor(boo) to toggle on/off the cursor.

You can use GraphicsWindow::requestWarpPointer(x,y) to position the mouse.

Robert.

 Any ideas?
 Im saving the mouse position before the drag with:


 Code:

 case(osgGA::GUIEventAdapter::PUSH):
 {
 osgViewer::View* view = dynamic_castosgViewer::View*(aa);
 if (view)
 {
 mouseDown = true;
 mouseResetX = ea.getX();
 mouseResetY = ea.getY();
 // somehow hide the mouse pointer here!!
 }

 return false;
 }



 I need a way to hide the mouse in the above code
 and show the mouse and set its position in the code below.


 Code:
 case(osgGA::GUIEventAdapter::RELEASE):
 {
 osgViewer::View* view = dynamic_castosgViewer::View*(aa);
 if (view)
 {
 // somehow show the mouse pointer and set its position here!!
 }

 return false;
 }


 ...

 Thank you!

 Cheers,
 Paul

  You don't say what OS you're on.

  You can show/hide the cursor with osgViewer's GraphicsWindow::setCursor() and 
request it
be repositioned with GraphicsWindow::requestWarpPointer().

Heres a screenshot of the chrome  look 3D GUI system ive created so far using 
osg. Dragging the mouse around, the reflections look quite impressive.
