Field Detail

exportChooser

protected javax.swing.JFileChooser exportChooser

Constructor Detail

ODGView

public ODGView()

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.

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.io.File f)
           throws java.io.IOException

Writes the view to the specified file.

Specified by:

write in interface View

Throws:

java.io.IOException

read

public void read(java.io.File f)
          throws java.io.IOException

Reads the view from the specified file.

Specified by:

read in interface View

Throws:

java.io.IOException

getDrawingEditor

public DrawingEditor getDrawingEditor()

Gets the drawing editor of the view.

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.

Specified by:

clear in interface View

createOpenChooser

protected javax.swing.JFileChooser createOpenChooser()

Overrides:

createOpenChooser in class AbstractView

createSaveChooser

protected javax.swing.JFileChooser createSaveChooser()

Overrides:

createSaveChooser in class AbstractView

canSaveTo

public boolean canSaveTo(java.io.File file)

Description copied from interface: View

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

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

Specified by:

canSaveTo in interface View

Overrides:

canSaveTo in class AbstractView

Parameters:

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

createExportChooser

protected javax.swing.JFileChooser createExportChooser()

getExportChooser

public javax.swing.JFileChooser getExportChooser()

Description copied from interface: ExportableView

Gets the file chooser for exporting the view.

Specified by:

getExportChooser in interface ExportableView

export

public void export(java.io.File f,
                   javax.swing.filechooser.FileFilter filter,
                   java.awt.Component accessory)
            throws java.io.IOException

Description copied from interface: ExportableView

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

Specified by:

export in interface ExportableView

Parameters:

f - The file to which export the view.

filter - The FileFilter that was used to choose the file. This can be null.

accessory - The Accessory used by the JFileChooser. This can be null.

Throws:

java.io.IOException
