// .NAME vtkInteractorStyleUser - provides customizable interaction routines
|
|
//
|
|
// .SECTION Description
|
|
// The most common way to customize user interaction is to write a subclass
|
|
// of vtkInteractorStyle: vtkInteractorStyleUser allows you to customize
|
|
// the interaction to without subclassing vtkInteractorStyle. This is
|
|
// particularly useful for setting up custom interaction modes in
|
|
// scripting languages such as Tcl and Python. This class allows you
|
|
// to hook into the MouseMove, ButtonPress/Release, KeyPress/Release,
|
|
// etc. events. If you want to hook into just a single mouse button,
|
|
// but leave the interaction modes for the others unchanged, you
|
|
// must use e.g. SetMiddleButtonPressMethod() instead of the more
|
|
// general SetButtonPressMethod().
