Class DefaultFloatPolicy

Method Details

• getInstance

  public static DefaultFloatPolicy getInstance()

  Returns a singleton instance of DefaultFloatPolicy.

  Returns:

  a singleton instance of DefaultFloatPolicy.

• isFloatDropAllowed

  public boolean isFloatDropAllowed(DockingEvent evt)

  Checks the previous DockingPort for the specified DockingEvent and returns false if it is in a floating dialog and contains less than two Dockables. A floating dialog may contain multiple Dockables, each of which may be dragged out of the current dialog to float in their own dialog. However, if a floating dialog only contains a single Dockable, it makes no sense to remove the Dockable only to float it within another dialog. This situation is caught by this method and the docking operation is blocked.

  Specified by:

  isFloatDropAllowed in interface FloatPolicy

  Overrides:

  isFloatDropAllowed in class FloatPolicy.NullFloatPolicy

  Parameters:

  evt - the DockingEvent to be checked for drop-to-float support

  Returns:

  false if the DockingEvent is attempting to float an already floating Dockable with no other Dockables in its current dialog; true otherwise.

  • DockingEvent.consume()

• isFloatingAllowed

  public boolean isFloatingAllowed(Dockable dockable)

  Blocks floating support (returns false) if dockable is null, if FloatPolicyManager.isGlobalFloatingEnabled() returns false, or if there are no entries within the Set returned by dockable.getFrameDragSources(). Otherwise, this method returns true.

  Specified by:

  isFloatingAllowed in interface FloatPolicy

  Overrides:

  isFloatingAllowed in class FloatPolicy.NullFloatPolicy

  Parameters:

  dockable - the Dockable to be checked for floating support

  Returns:

  false if floating is blocked for the specified Dockable; true otherwise.
