Summary0012531: vtkScalarBarRepresentation should only change orientation when moving, not resizing
DescriptionWhen a user drags the edges of a vtkScalarBarWidget, and the mouse passes close to the edge of the view, often the bar will change orientation which can result in the bar jumping around the screen.

In this method:

void vtkScalarBarRepresentation::WidgetInteraction(double eventPos[2])
{
  // Let superclass move things around.
  this->Superclass::WidgetInteraction(eventPos);

  // Check to see if we need to change the orientation.
etc etc

at this point, the rest of the code should not be executed if the user is not moving with widget.

So, adding this test around the reorientation code improves the scalar bar behaviour a lot.

if (this->Moving)
{
  // Check to see if we need to change the orientation.
  etc etc code for reorientating bar
}

cheers

 Does the problem still occur with VTK 5.10 ? VTK 6 ?

Would be great if you could submit a patch using Gerrit. For more details see http://www.vtk.org/Wiki/VTK/Git/Develop [^]

Thanks

    BUG 12531: Fixed problem with AutoOrient
    
    When resizing a vtkScalarBarWidget while AutoOrient is enabled, the
    scalar bar orientation may change while the dimension whose size is
    changing will not. This is odd behavior that can result in the scalar
    bar jumping around during resizing or the widget completely
    collapsing, making it impossible to interact with the widget.
    
    Fixed this by disallowing orientation swaps when the scalar bar
    representation is not moving.
    
    Modified TestScalarBarWidget.cxx to test this change.
