getPreferredSize

public Dimension getPreferredSize()

Description copied from class: Component

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

Overrides:

getPreferredSize in class Component

computePreferredSize

protected Dimension computePreferredSize()

Description copied from class: Component

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.

Overrides:

computePreferredSize in class Component

setPreferredSize

public void setPreferredSize(Dimension d)

Description copied from class: Component

Sets the preferred size of the object for layout purposes

Overrides:

setPreferredSize in class Component

calculatePreferredSize

protected Dimension calculatePreferredSize()

Description copied from class: Component

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)

Overrides:

calculatePreferredSize in class Component

getMaximumSize

public Dimension getMaximumSize()

Description copied from class: Component

Returns the maximum size of the component

Overrides:

getMaximumSize in class Component

Overrides:

setSize

public void setSize(Dimension d)

Description copied from class: Component

Sets the peer's actual size

Overrides:

setSize in class Component

getSize

public Dimension getSize()

Description copied from class: Component

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.

Overrides:

getSize in class Component

getPeerSize

public Dimension getPeerSize()

Description copied from class: Component

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