Method Detail

createEditor

protected javax.swing.JTextPane createEditor()

init

public void init()

Description copied from class: AbstractView

Initializes the view. This method does nothing, subclasses don't neet to call super.

Specified by:

init in interface View

Overrides:

init in class AbstractView

setEnabled

public void setEnabled(boolean newValue)

Description copied from interface: View

Sets the enabled state of the view. The enabled state is used to prevent parallel invocation of actions on the view. If an action consists of a sequential part and a concurrent part, it must disable the view only for the sequential part. Actions that act on the view must check in their actionPerformed method whether the view is enabled. If the view is disabled, they must do nothing. If the view is enabled, they must disable the view, perform the action and then enable the view again. This is a bound property.

Specified by:

setEnabled in interface View

Overrides:

setEnabled in class javax.swing.JComponent

setStatusBarVisible

public void setStatusBarVisible(boolean newValue)

isStatusBarVisible

public boolean isStatusBarVisible()

setLineWrap

public void setLineWrap(boolean newValue)

isLineWrap

                  URIChooser chooser)
           throws java.io.IOException

Description copied from interface: View

Writes the view to the specified URI.

By convention this method is never invoked on the AWT Event Dispatcher Thread.

Parameters:

f - The location where to write the view.
