Constructor Detail

DrawView

public DrawView()
Creates a new view.

Method Detail

init

public void init()
Initializes the view.

Specified by:
init in interface View
Overrides:
init 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.


setHasUnsavedChanges

protected void setHasUnsavedChanges(boolean newValue)
Overrides:
setHasUnsavedChanges in class AbstractView

write

public void write(java.net.URI f,
                  URIChooser fc)
           throws java.io.IOException
Writes the view to the specified uri.

Parameters:
f - The location where to write the view.
fc - 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 f,
                 URIChooser fc)
          throws java.io.IOException
Reads the view from the specified uri.

Parameters:
f - The location where to write the view.
fc - The chooser which was used for selecting the URI. This parameter is null if no chooser was used.
Throws:
java.io.IOException

setEditor

public void setEditor(DrawingEditor newValue)
Sets a drawing editor for the view.


getEditor

public DrawingEditor getEditor()
Gets the drawing editor of the view.


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.
