public class RepaintManager

extends Object

managers

RepaintManager()

Create a new RepaintManager instance.

addDirtyRegion(JComponent, int, int, int, int)

Add a component in the list of component that should be refreshed.

addInvalidComponent(JComponent)

currentManager()

Return the RepaintManager for the calling thread.

getDirtyRegion(JComponent)

Return the current dirty region for a component.

getDoubleBufferMaximumSize()

getOffscreenBuffer(Component, int, int)

Return the offscreen buffer that should be used as a double buffer with the component c By default there is a double buffer per RepaintManager.

isCompletelyDirty(JComponent)

Convenience that returns true if aComponent will be completely painted during the next paintDirtyRegions().

isDoubleBufferingEnabled()

markCompletelyClean(JComponent)

Mark a component completely clean.

markCompletelyDirty(JComponent)

Mark a component completely dirty.

paintDirtyRegions()

Cause all the known dirty regions to be painted

removeInvalidComponent(JComponent)

Remove an invalid component

repaintDirtyRegions()

setCurrentManager(RepaintManager)

Set the RepaintManager that should be used for the calling thread.

setDoubleBufferingEnabled(boolean)

setDoubleBufferMaximumSize(Dimension)

Set the maximum double buffer size.

toString()

Returns a string representation of the object.

validateInvalidComponents()

Cause all invalide component to get validated

public static Hashtable managers

public RepaintManager()

Create a new RepaintManager instance. You rarely call this constructor. directly. To get the default RepaintManager, use RepaintManager.currentManager()

public static RepaintManager currentManager()

Return the RepaintManager for the calling thread. This method will maintain one RepaintManager per thread group.

public static void setCurrentManager(RepaintManager aRepaintManager)

Set the RepaintManager that should be used for the calling thread. aRepaintManager will become the current RepaintManager for the calling thread's thread group.

public void addInvalidComponent(JComponent component)

public void removeInvalidComponent(JComponent component)

Remove an invalid component

public void addDirtyRegion(JComponent aComponent,
                           int x,
                           int y,
                           int w,
                           int h)

Add a component in the list of component that should be refreshed. If aComponent already has some dirty region, the rectangle (x,y,w,h) will be added to the region that should be redrawn.

public Rectangle getDirtyRegion(JComponent aComponent)

Return the current dirty region for a component. Return an empty rectangle if the component is not dirty.

public void markCompletelyDirty(JComponent aComponent)

Mark a component completely dirty. aComponent will be completely painted during the next paintDirtyRegions() call.

public void markCompletelyClean(JComponent aComponent)

Mark a component completely clean. aComponent will not get painted during the next paintDirtyRegions() call

public boolean isCompletelyDirty(JComponent aComponent)

Convenience that returns true if aComponent will be completely painted during the next paintDirtyRegions(). If computing dirty regions is expensive for your component, use this method and avoid computing dirty region if it return true.

public void repaintDirtyRegions()

public void validateInvalidComponents()

Cause all invalide component to get validated

public void paintDirtyRegions()

Cause all the known dirty regions to be painted

public String toString()

Returns a string representation of the object.

Overrides:

toString in class Object

public Image getOffscreenBuffer(Component c,
                                int proposedWidth,
                                int proposedHeight)

Return the offscreen buffer that should be used as a double buffer with the component c By default there is a double buffer per RepaintManager. The buffer might be smaller than (proposedWidth,proposedHeight) This happens when the maximum double buffer size as been set for the receiving repaint manager.

public void setDoubleBufferMaximumSize(Dimension d)

Set the maximum double buffer size.

public Dimension getDoubleBufferMaximumSize()

public void setDoubleBufferingEnabled(boolean aFlag)

public boolean isDoubleBufferingEnabled()
