Field Detail

GRID_VISIBLE_PROPERTY

public static final java.lang.String GRID_VISIBLE_PROPERTY
See Also:
Constant Field Values

exportChooser

protected JFileURIChooser exportChooser
Constructor Detail

ODGView

public ODGView()
Creates a new view.

Method Detail

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)

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

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

setPropertiesPanelVisible

public void setPropertiesPanelVisible(boolean newValue)

isPropertiesPanelVisible

public boolean isPropertiesPanelVisible()

isGridVisible

public boolean isGridVisible()

setGridVisible

public void setGridVisible(boolean newValue)

getScaleFactor

public double getScaleFactor()

setScaleFactor

public void setScaleFactor(double newValue)

clear

public void clear()
Clears the view.


canSaveTo

public boolean canSaveTo(java.net.URI uri)
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:
uri - An URI. If this parameter is null, a NullPointerException is thrown.
