getDispatchPriority

protected int getDispatchPriority()

Description copied from class: Tool

Overrides:

getDispatchPriority in class Tool

Returns:

the dispatch priority

handleEditEvent

protected void handleEditEvent(boolean isActive,
 EditEvent e)

Description copied from class: Tool

Handle the given EditEvent. This method dispatches the edit event to the individual handleXYZ()-Methods. However, implementors may want and are allowed to override this method in order to perform standard handling tasks common to all types of events.

Overrides:

handleEditEvent in class Tool

isActive - whether this tool is currently active

e - the event

setModifierAndButtonMask

public void setModifierAndButtonMask(int modifierAndButtonMask)

setUseIdlePanModeCursor

public void setUseIdlePanModeCursor(boolean useIdlePanModeCursor)
