exportChooser

protected JFileURIChooser exportChooser

Constructor Detail

SVGView

public SVGView()

Creates a new View.

Method Detail

dispose

public void dispose()

Description copied from class: AbstractView

Gets rid of all the resources of the view. No other methods should be invoked on the view afterwards.

Specified by:

dispose in interface Disposable

Specified by:

dispose in interface View

Overrides:

dispose in class AbstractView

createDrawing

protected Drawing createDrawing()

Creates a new Drawing for this View.

createPageable

public java.awt.print.Pageable createPageable()

Creates a Pageable object for printing the View.

getEditor

public DrawingEditor getEditor()

setEditor

public void setEditor(DrawingEditor newValue)

getUndoManager

public UndoRedoManager getUndoManager()

setHasUnsavedChanges

protected void setHasUnsavedChanges(boolean newValue)

Overrides:

setHasUnsavedChanges in class AbstractView

write

public void write(java.net.URI uri,
                  URIChooser chooser)
           throws java.io.IOException

Writes the view to the specified uri.

Parameters:

uri - The location where to write the view.

chooser - The chooser which was used for selecting the URI. This parameter is null if no chooser was used.

Throws:

java.io.IOException

read

public void read(java.net.URI uri,
                 URIChooser chooser)
          throws java.io.IOException

Reads the view from the specified uri.

Parameters:

uri - The location where to write the view.

chooser - The chooser which was used for selecting the URI. This parameter is null if no chooser was used.

Throws:

java.io.IOException

getDrawing

public Drawing getDrawing()

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

clear

public void clear()

Clears the view.

canSaveTo

public boolean canSaveTo(java.net.URI file)

Description copied from interface: View

Returns true, if this view can be saved to the specified URI. A reason why the view can't be saved to a URI, is that the view is unable to write to a file-URI with the given filename extension without losing data.

The SaveAction uses this method to decide, whether to display a save dialog before saving the URI.

Specified by:

canSaveTo in interface View

Overrides:

canSaveTo in class AbstractView

Parameters:

file - An URI. If this parameter is null, a NullPointerException is thrown.
