Method Detail

focusGained

public void focusGained(java.awt.event.FocusEvent event)

Called when the component containing the caret gains focus. This is implemented to set the caret to visible if the component is editable.

Specified by:

focusGained in interface java.awt.event.FocusListener

Overrides:

focusGained in class BasicCaret

Parameters:

e - the focus event

See Also:

Called when the mouse is clicked. Override this to handle drag initiation.

Specified by:

mouseClicked in interface java.awt.event.MouseListener

Overrides:

mouseClicked in class BasicCaret

Parameters:

event - the mouse event

See Also:

MouseListener.mouseClicked(java.awt.event.MouseEvent)

mouseDragged

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