constructor:BasicToolTipUI() [NONE]

BasicToolTipUI

public BasicToolTipUI()

Constructs a new instance of BasicToolTipUI.

method:createUI(javax.swing.JComponent) [NONE]

createUI

public static ComponentUI createUI?(JComponent c)

Returns the instance of BasicToolTipUI.

Parameters:: c - a component
Returns:: the instance of BasicToolTipUI

method:installUI(javax.swing.JComponent) [NONE]

installUI

public void installUI?(JComponent c)

Description copied from class: ComponentUI

Configures the specified component appropriately for the look and feel. This method is invoked when the ComponentUI instance is being installed as the UI delegate on the specified component. This method should completely configure the component for the look and feel, including the following:

Install default property values for color, fonts, borders, icons, opacity, etc. on the component. Whenever possible, property values initialized by the client program should not be overridden.
Install a LayoutManager on the component if necessary.
Create/add any required sub-components to the component.
Create/install event listeners on the component.
Create/install a PropertyChangeListener on the component in order to detect and respond to component property changes appropriately.
Install keyboard UI (mnemonics, traversal, etc.) on the component.
Initialize any appropriate instance data.

Overrides:: installUI in class ComponentUI
Parameters:: c - the component where this UI delegate is being installed
See Also:: ComponentUI.uninstallUI(javax.swing.JComponent), JComponent.setUI(javax.swing.plaf.ComponentUI), JComponent.updateUI()

method:uninstallUI(javax.swing.JComponent) [NONE]

uninstallUI

public void uninstallUI?(JComponent c)

Description copied from class: ComponentUI

Reverses configuration which was done on the specified component during installUI. This method is invoked when this UIComponent instance is being removed as the UI delegate for the specified component. This method should undo the configuration performed in installUI, being careful to leave the JComponent instance in a clean state (no extraneous listeners, look-and-feel-specific property objects, etc.). This should include the following:

Remove any UI-set borders from the component.
Remove any UI-set layout managers on the component.
Remove any UI-added sub-components from the component.
Remove any UI-added event/property listeners from the component.
Remove any UI-installed keyboard UI from the component.
Nullify any allocated instance data objects to allow for GC.

Overrides:: uninstallUI in class ComponentUI
Parameters:: c - the component from which this UI delegate is being removed; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
See Also:: ComponentUI.installUI(javax.swing.JComponent), JComponent.updateUI()

method:installDefaults(javax.swing.JComponent) [NONE]

installDefaults

protected void installDefaults?(JComponent c)

Installs default properties.

Parameters:: c - a component

method:uninstallDefaults(javax.swing.JComponent) [NONE]

uninstallDefaults

protected void uninstallDefaults?(JComponent c)

Uninstalls default properties.

Parameters:: c - a component

method:installListeners(javax.swing.JComponent) [NONE]

installListeners

protected void installListeners?(JComponent c)

Registers listeners.

Parameters:: c - a component

method:uninstallListeners(javax.swing.JComponent) [NONE]

uninstallListeners

protected void uninstallListeners?(JComponent c)

Unregisters listeners.

Parameters:: c - a component

method:paint(java.awt.Graphics,javax.swing.JComponent) [NONE]

paint

public void paint?(Graphics g, JComponent c)

Description copied from class: ComponentUI

Paints the specified component appropriately for the look and feel. This method is invoked from the ComponentUI.update method when the specified component is being painted. Subclasses should override this method and use the specified Graphics object to render the content of the component.

Overrides:: paint in class ComponentUI
Parameters:: g - the Graphics context in which to paint; c - the component being painted; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
See Also:: ComponentUI.update(java.awt.Graphics, javax.swing.JComponent)

method:getPreferredSize(javax.swing.JComponent) [NONE]

getPreferredSize

public Dimension getPreferredSize?(JComponent c)

Description copied from class: ComponentUI

Returns the specified component's preferred size appropriate for the look and feel. If null is returned, the preferred size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method returns null.

Overrides:: getPreferredSize in class ComponentUI
Parameters:: c - the component whose preferred size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
Returns:: a Dimension object containing given component's preferred size appropriate for the look and feel
See Also:: JComponent.getPreferredSize(), LayoutManager.preferredLayoutSize(java.awt.Container)

method:getMinimumSize(javax.swing.JComponent) [NONE]

getMinimumSize

public Dimension getMinimumSize?(JComponent c)

Description copied from class: ComponentUI

Returns the specified component's minimum size appropriate for the look and feel. If null is returned, the minimum size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method invokes getPreferredSize and returns that value.

Overrides:: getMinimumSize in class ComponentUI
Parameters:: c - the component whose minimum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
Returns:: a Dimension object or null
See Also:: JComponent.getMinimumSize(), LayoutManager.minimumLayoutSize(java.awt.Container), ComponentUI.getPreferredSize(javax.swing.JComponent)

method:getMaximumSize(javax.swing.JComponent) [NONE]

getMaximumSize

public Dimension getMaximumSize?(JComponent c)

Description copied from class: ComponentUI

Returns the specified component's maximum size appropriate for the look and feel. If null is returned, the maximum size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method invokes getPreferredSize and returns that value.

Overrides:: getMaximumSize in class ComponentUI
Parameters:: c - the component whose maximum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
Returns:: a Dimension object or null
See Also:: JComponent.getMaximumSize(), LayoutManager2.maximumLayoutSize(java.awt.Container)
