Constructs a new format action for the specified name. If the action name starts with toggle or switch then the action is configured to be a toggle action.

Parameters:

name - The name of the action to be created.

Method Detail

actionPerformed

public void actionPerformed(ActionEvent event)

Executes the action based on the action name.

Parameters:

event - The object that describes the event.

public Font fontDialog(Component component,
                       String title,
                       Font font)

Displays a font dialog using JGraphpadDialogs.fontDialog(Component, String). This hook is overridden in the l2f plugin to provide a better dialog.

Parameters:

component - The parent component for the dialog to be displayed.

title - The title of the dialog to be displayed.

font - The default font to use in the dialog.

Returns:

Returns the selected font.

setRouting

protected void setRouting(org.jgraph.JGraph graph,
                          org.jgraph.graph.Edge.Routing routing)

Changes the font style on the specified component to style, which may be one of Font.BOLD, Font.ITALIC or FONT_UNDERLINE. This implementation changes the style of either the selection cells in JGraph or the selection text in JTextPane.

Parameters:

graph - The graph to change the font in.

routing - The routing to use.

doSetDashPattern

protected void doSetDashPattern(org.jgraph.JGraph graph)

Changes the dash pattern in the selection edges of the specified graph by displaying a dialog to enter a dash sequence of the form [n[,n[,n]*]] where n is a number.

Parameters:

graph - The graph to change the dash pattern in.

doSetFont

protected void doSetFont(Component component,
                         Object change,
                         boolean plain,
                         int style,
                         float size)
                  throws BadLocationException

Changes the font on the specified component to change, which may be either a Font or Color object, changing the respective font property of either the selection cells in JGraph or the selection text in JTextPane.

Parameters:

component - The component to change the font in.

change - The value to change the font to.

Throws:

BadLocationException

doSetHorizontalAlignment

protected void doSetHorizontalAlignment(Component component,
                                        int align)

Changes the horizontal alignment on the specified component to align, which may be one of SwingConstants.LEFT, SwingConstants.CENTER or SwingConstants.RIGHT. This implementation changes the horizontal aligment of either the selection cells in JGraph or the selection text in JTextPane, however, the alignment in textpanes is not persisted due to a bug in Swing (so end users should align cells, not selection rich text).

Parameters:

component - The component to change the font in.

align - The horizontal alignment to use.

doAskIntAttribute

protected void doAskIntAttribute(org.jgraph.JGraph graph,
                                 String key,

Displays a dialog to ask for a number and uses the number to set the attribute under key for the selected cells in graph. The default value is used in the dialog.

Parameters:

graph - The graph to perform the operation in.

key - The key of the attribute to be changed.

defaultValue - The default value for the number dialog.

doAskFloatAttribute

protected void doAskFloatAttribute(org.jgraph.JGraph graph,
                                   String key,
                                   float defaultValue)

Displays a dialog to ask for a number and uses the number to set the attribute under key for the selected cells in graph. The default value is used in the dialog.

Parameters:

graph - The graph to perform the operation in.

key - The key of the attribute to be changed.

defaultValue - The default value for the number dialog.

                                   boolean setOpaque)

Displays a dialog to ask for a color and uses the color to set the attribute under key for the selected cells in graph. If setOpaque is true then the opaque attribute will be set to true.

Parameters:

graph - The graph to perform the operation in.

key - The key of the attribute to be changed.

setOpaque - Whether to make the affected cells opaque.
