Class MouseReselect

java.lang.Object
  com.ibm.lpex.core.LpexViewAdapter
      com.ibm.lpex.samples.MouseReselect

All Implemented Interfaces:

LpexViewListener

public class MouseReselect
extends LpexViewAdapter

Sample class to make new drags of mouse button 1 start new selections.

LPEX non-stream selections are by default extended on mouse drags in the same view. They must be explicitly cleared (with, for example, Alt+U) before marking a new block. Installing this class changes the default behavior of a view such that a new mouse drag action (mouse button 1 with no key modifiers) will always start a new selection.

Here is the MouseReselect source code.

A user profile (such as TestUserProfile) can install this feature in a document view by calling:

  MouseReselect.install(lpexView);

See also BlockNewMarkToMouseAction as an example of an editor action that installs this feature when it is run for the first time.
