paintComponent
public void paintComponent(java.awt.Graphics _g)
- Description copied from class:
javax.swing.JComponent
- Paint the component's body. This usually means calling ComponentUI.update(java.awt.Graphics, javax.swing.JComponent)>
ComponentUI.update(java.awt.Graphics, javax.swing.JComponent) 55 on the JComponent.ui>JComponent.ui 55 property of the component, if
it is non-null. You may override this if you wish to
customize the component's body-painting behavior. The component's body
is painted first, before the border and children.

getImageWidth

getImageHeight

getPreferredSize
public java.awt.Dimension getPreferredSize()
- Description copied from class:
javax.swing.JComponent
- Get the component's preferred size. If the JComponent.preferredSize>
JComponent.preferredSize 55
property has been explicitly set, it is returned. If the JComponent.preferredSize>JComponent.preferredSize 55 property has not been set but the JComponent.ui>JComponent.ui 55 property
has been, the result of ComponentUI.getPreferredSize(javax.swing.JComponent)>ComponentUI.getPreferredSize(javax.swing.JComponent) 55 is
returned. If neither property has been set, the result of Container.getPreferredSize()>Container.getPreferredSize() 55 is returned.
finalize
public void finalize()
- Description copied from class:
java.lang.Object
- Called on an object by the Virtual Machine at most once,
at some point after the Object is determined unreachable
but before it is destroyed. You would think that this
means it eventually is called on every Object, but this is
not necessarily the case. If execution terminates
abnormally, garbage collection does not always happen.
Thus you cannot rely on this method to always work.
For finer control over garbage collection, use references
from the
java.lang.ref package.
Virtual Machines are free to not call this method if
they can determine that it does nothing important; for
example, if your class extends Object and overrides
finalize to do simply super.finalize().
finalize() will be called by a java.lang.Thread that has no
locks on any Objects, and may be called concurrently.
There are no guarantees on the order in which multiple
objects are finalized. This means that finalize() is
usually unsuited for performing actions that must be
thread-safe, and that your implementation must be
use defensive programming if it is to always work.
If an Exception is thrown from finalize() during garbage
collection, it will be patently ignored and the Object will
still be destroyed.
It is allowed, although not typical, for user code to call
finalize() directly. User invocation does not affect whether
automatic invocation will occur. It is also permitted,
although not recommended, for a finalize() method to "revive"
an object by making it reachable from normal code again.
Unlike constructors, finalize() does not get called
for an object's superclass unless the implementation
specifically calls super.finalize().
The default implementation does nothing.
