mousePressed

public void mousePressed(java.awt.event.MouseEvent e)

Invoked when a mouse button has been pressed on a component.

Specified by:

mousePressed in interface java.awt.event.MouseListener

Overrides:

mousePressed in class java.awt.event.MouseAdapter

mouseClicked

public void mouseClicked(java.awt.event.MouseEvent e)

Specified by:

mouseClicked in interface java.awt.event.MouseListener

Overrides:

mouseClicked in class java.awt.event.MouseAdapter

handleEditTrigger

protected void handleEditTrigger(java.lang.Object cell,
                                 java.awt.event.MouseEvent e)

mouseDragged

public void mouseDragged(java.awt.event.MouseEvent e)

Specified by:

mouseDragged in interface java.awt.event.MouseMotionListener

mouseMoved

public void mouseMoved(java.awt.event.MouseEvent e)

Invoked when the mouse pointer has been moved on a component (with no buttons down).

Specified by:

mouseMoved in interface java.awt.event.MouseMotionListener

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent e)

Specified by:

mouseReleased in interface java.awt.event.MouseListener

Overrides:

mouseReleased in class java.awt.event.MouseAdapter

postProcessSelection

protected void postProcessSelection(java.awt.event.MouseEvent e,
                                    java.lang.Object cell,
                                    boolean wasSelected)

Invoked after a cell has been selected in the mouseReleased method. This can be used to do something interesting if the cell was already selected, in which case this implementation selects the parent. Override if you want different behaviour, such as start editing.

isDescendant

protected boolean isDescendant(CellView parentView,
                               CellView childView)
