Method Detail

paint

public void paint(Graphics g)

Override in subclasses to paint on the component

paintComponent

protected void paintComponent(Graphics g)

Not normally in Component - member of JComponent, implemented here to save a load of class casting around and to call into paint(Graphics) - this is the first point of call for repainting..

setSwingWTParent

public void setSwingWTParent(Container parent)
                      throws java.lang.Exception

Once a parent component receives an "add" call for a child, this being the child, this should be called to tell us to instantiate the peer and load in any cached properties.

Throws:

Returns the SWT peer

getPeer

public ComponentPeer getPeer()

                    int height)

repaint

public void repaint(long tm,
                    int x,
                    int y,
                    int width,
                    int height)

getGraphics

public Graphics getGraphics()

Return a graphics context for drawing on this object. Note that only instances of JComponent are allowed

getPreferredSize

public Dimension getPreferredSize()

Returns the preferred size the component would like to be displayed at - very important for proper layout managers.

computePreferredSize

protected Dimension computePreferredSize()

This is called by getPreferredSize() when we want the peer to compute it's own size. This base method delegates to the peer, but some components may want to override this value hence the reason we have a separate method here. NOTE THAT THIS ROUTINE IS DIFFERENT FROM calculatePreferredSize() - this routine is called by getPreferredSize() when none has been set by the user and allows the peer to compute it's size, calculatePreferredSize() is used when no peer has been created and we need to guess an appropriate size.

setPreferredSize

public void setPreferredSize(Dimension d)

Sets the preferred size of the object for layout purposes

calculatePreferredSize

protected Dimension calculatePreferredSize()

Override in subclasses to return the preferred size for a given (non-realised) component. Note that you should use setSize() to whatever this routine returns once called to prevent inconsistency with null layout managers. Also note that this is different from the computePreferredSize() method, which is used for calculating the preferredSize of a realised component (this one is for unrealised components)

getMaximumSize

public Dimension getMaximumSize()

Returns the maximum size of the component

setMaximumSize

public void setMaximumSize(Dimension d)

Sets the maximum size of the component

getMinimumSize

public Dimension getMinimumSize()

public boolean isMinimumSizeSet()

setSize

public void setSize(int width,
                    int height)

Sets the peer's actual size

setSize

public void setSize(Dimension d)

Sets the peer's actual size

contains

public boolean contains(int x,
                        int y)

contains

public boolean contains(Point point)

inside

public boolean inside(int x,
                      int y)

getSize

public Dimension getSize()

Returns the peers actual size. Or, if the peer is embedded inside a ScrollPane component, the larger of the preferredSize/peers actual size. This works rather nicely for handling layouts inside a scrollbar as we can simply offset a large composite according to the scrollbar positions inside JScrollPane. One note - if the component is JTree, JTable, JTextArea or JEditorPane, then we return the size as usual since these components handle their own scrolling and we don't want the JScrollPane behaving weirdly.

getSize

public Dimension getSize(Dimension rv)

Overloaded version of getSize() that uses the passed in dimension to put the size in to prevent allocation of another on the heap. NB: Still creates a new dimension due to how SwingWT works so there is no benefit to using this method.

getPeerSize

public Dimension getPeerSize()

Returns the peers actual size, or 0,0 if it hasn't been created yet/is invisible

setFocusTraversalKeysEnabled

public void setFocusTraversalKeysEnabled(boolean b)

FIXME: NOT IMPLEMENTED

public Image createImage(int width,
                         int height)

Creates and returns an image

Specified by:

getFont in interface MenuContainer

setFont

Returns the tooltip text used on the component

setToolTipText

public void setToolTipText(java.lang.String text)

Sets the tooltip text used on the component

                      int y,
                      int width,

setCachedProperties

public void setCachedProperties()

If the component has just been added to a container, but properties were set in the meantime, this routine gets called by JSWTComposite to set the cached properties.

registerEvents

public void registerEvents()

When the component has been added to a container, this routine gets called to tell it to set up SWT listeners for all its events. We can map these then to the AWT-style events

registerPaintEvents

protected void registerPaintEvents()

registerTraversalEvents

protected void registerTraversalEvents()

registerFocusEvents

protected void registerFocusEvents()

registerComponentEvents

protected void registerComponentEvents()

registerMouseEvents

protected void registerMouseEvents()

registerKeyEvents

protected void registerKeyEvents()

registerActionEvents

protected void registerActionEvents()

registerModifyEvents

protected void registerModifyEvents()

Handle ModifyEvents (maps to ImputMethodEvents) by checking the final derivation of this Component. Unusual way to do it, but since InputMethodEvents are handled in the base Component, unlike SWT, it's the most effective way to maintain backwards compatibility. This method is being used for speed - the alternatives are to use peer.getClass().getMethod(...) or peer.getClass().getMethods() and search for required methods. getMethod() has the problem of throwing an exception, which will eat up resources given how often this code will be called. getMethods(), likewise, will usually return a very large list, taking a long time to traverse. This means if SWT is updated to have new components return ModifyEvents, it will need to be added here.

registerExtendedModifyEvents

protected void registerExtendedModifyEvents()

Same as above, but for ExtendedModifyEvents

processTraverseEvent

protected void processTraverseEvent(org.eclipse.swt.events.TraverseEvent e)

Called when a traversal key is pressed by the user. This routine determines whether we should use the custom focus manager if one is avaliable, or just let it go.

setComponentRemoved

protected void setComponentRemoved()

When a container removes a component, it calls this method. You can override this in your subclass to perform any specific action you need to take when that component is removed.

imageUpdate

public boolean imageUpdate(Image img,
                           int infoflags,

Here for compatibility - I'm not sure what it's for. Doesn't do anything anyway. :-)

Specified by:

imageUpdate in interface ImageObserver

hasFocus

public boolean hasFocus()

Returns true if this component has the focus

getTreeLock

public java.lang.Object getTreeLock()

For compatibility with 3rd party layout managers - SwingWT doesn't need this as all laying out is marshalled onto a queued single thread

public AccessibleContext getAccessibleContext()

Returns the component's accessible context
