Constructor Detail

BasicInternalFrameTitlePane.SystemMenuBar

public BasicInternalFrameTitlePane.SystemMenuBar()
Method Detail

isFocusTraversable

public boolean isFocusTraversable()
Description copied from class: JComponent
Identifies whether or not this component can receive the focus. A disabled button, for example, would return false.
Overrides:
isFocusTraversable in class JComponent
Tags copied from class: JComponent
Returns:
true if this component can receive the focus

requestFocus

public void requestFocus()
Description copied from class: JComponent
Set focus on the receiving component if isRequestFocusEnabled returns true
Overrides:
requestFocus in class JComponent
Tags copied from class: Component
See Also:
FocusEvent, Component.addFocusListener(java.awt.event.FocusListener), Component.processFocusEvent(java.awt.event.FocusEvent), Component.isFocusTraversable()

paint

public void paint(Graphics g)
Description copied from class: JComponent
This method is invoked by Swing to draw components. Applications should not invoke paint directly, but should instead use the repaint method to schedule the component for redrawing.

This method actually delegates the work of painting to three protected methods: paintComponent, paintBorder, and paintChildren. They're called in the order listed to ensure that children appear on top of component itself. Generally speaking, the component and its children should not paint in the insets area allocated to the border. Subclasses can just override this method, as always. A subclass that just wants to specialize the UI (look and feel) delegates paint method should just override paintComponent.

Overrides:
paint in class JComponent
Tags copied from class: JComponent
See Also:
JComponent.paintComponent(java.awt.Graphics), JComponent.paintBorder(java.awt.Graphics), JComponent.paintChildren(java.awt.Graphics), JComponent.getComponentGraphics(java.awt.Graphics), JComponent.repaint(long, int, int, int, int)

isOpaque

public boolean isOpaque()
Description copied from class: JComponent
Returns true if this component is completely opaque.

An opaque component paints every pixel within its rectangular region. A non-opaque component paints only some of its pixels, allowing the pixels underneath it to "show through". A component that does not fully paint its pixels therefore provides a degree of transparency.

Subclasses that guarantee to always completely paint their contents should override this method and return true.

This method will migrate to java.awt.Component in the next major JDK release

Overrides:
isOpaque in class JComponent
Tags copied from class: JComponent
Returns:
true if this component is completely opaque.
See Also:
JComponent.setOpaque(boolean)
