Method Detail

setVisitingDelegate

public void setVisitingDelegate(ActionListener delegate)

The delegate to invoke on actionPerformed.

The delegates actionPerformed is invoked with an ActionEvent having the target as source. Delegates are expected to cope gracefully with the T.

PENDING: JW - How to formalize?

Parameters:

delegate - the action invoked on the target.

actionPerformed

public void actionPerformed(ActionEvent e)

This action delegates to the visitingDelegate if both delegate and target are != null, does nothing otherwise. The actionEvent carries the target as source. PENDING: pass through a null target? - most probably!

installTarget

protected void installTarget()

installs a propertyChangeListener on the target and updates the visual properties from the target.

Overrides:

installTarget in class LinkAction<T extends LinkModel>

uninstallTarget

protected void uninstallTarget()

removes the propertyChangeListener.

Implementation NOTE: this does not clean-up internal state! There is no need to because updateFromTarget handles both null and not-null targets. Hmm...

Overrides:

uninstallTarget in class LinkAction<T extends LinkModel>

updateFromTarget

protected void updateFromTarget()
