Overrides:

updateUI in class javax.swing.JComponent

See Also:

JComponent.updateUI()

getUI

public FontChooserUI getUI()

Returns the look and feel (L&F) object that renders this component.

Returns:

the PanelUI object that renders this component

Since:

1.4

setUI

public void setUI(FontChooserUI ui)

Sets the look and feel (L&F) object that renders this component.

Parameters:

ui - the PanelUI L&F object

See Also:

UIDefaults.getUI(javax.swing.JComponent)

getUIClassID

public java.lang.String getUIClassID()

Returns a string that specifies the name of the L&F class that renders this component.

Overrides:

getUIClassID in class javax.swing.JComponent

Returns:

"FontChooserUI"

See Also:

JComponent.getUIClassID(), UIDefaults.getUI(javax.swing.JComponent)

approveSelection

public void approveSelection()

Called by the UI when the user hits the Approve button (labeled "Open" or "Save", by default). This can also be called by the programmer. This method causes an action event to fire with the command string equal to APPROVE_SELECTION.

See Also:

APPROVE_SELECTION

cancelSelection

public void cancelSelection()

Called by the UI when the user chooses the Cancel button. This can also be called by the programmer. This method causes an action event to fire with the command string equal to CANCEL_SELECTION.

See Also:

CANCEL_SELECTION

addActionListener

public void addActionListener(java.awt.event.ActionListener l)

Adds an ActionListener to the font chooser.

Parameters:

l - the listener to be added

See Also:

approveSelection(), cancelSelection()

removeActionListener

public void removeActionListener(java.awt.event.ActionListener l)

Removes an ActionListener from the font chooser.

Parameters:

l - the listener to be removed

See Also:

addActionListener(java.awt.event.ActionListener)

fireActionPerformed

protected void fireActionPerformed(java.lang.String command)

Notifies all listeners that have registered interest for notification on this event type. The event instance is lazily created using the command parameter.

getSelectionPath

public javax.swing.tree.TreePath getSelectionPath()

Gets the selected Font. This is a bound property.

Returns:

The selected font, or null, if no font is selected.

setSelectionPath

Sets the selected Font. This is a bound property.

Changing the selection path, causes a change of the selected font, if the selected font is not the last path segment of the selection path.

Parameters:

newValue - The new selected font, or null if no font is to be selected..

loadAllFonts

public static void loadAllFonts()

Starts loading all fonts from the local graphics environment using a worker thread.

getAllFonts

public static java.awt.Font[] getAllFonts()

Returns:

All fonts.

getSelectedFont

public java.awt.Font getSelectedFont()

Gets the selected Font. This is a bound property.
