Method Detail

addNotifyback to summary
public void addNotify()

Overrides java.awt.Panel.addNotify.

Doc from java.awt.Panel.addNotify.

Creates the Panel's peer. The peer allows you to modify the appearance of the panel without changing its functionality.

getPreferredSizeback to summary
public Dimension getPreferredSize()

Overrides java.awt.Container.getPreferredSize.

Doc from java.awt.Container.getPreferredSize.

Returns the preferred size of this container. If the preferred size has not been set explicitly by Component#setPreferredSize(Dimension) and this Container has a non-null LayoutManager, then LayoutManager#preferredLayoutSize(Container) is used to calculate the preferred size.

Note

some implementations may cache the value returned from the LayoutManager. Implementations that cache need not invoke preferredLayoutSize on the LayoutManager every time this method is invoked, rather the LayoutManager will only be queried after the Container becomes invalid.

Returns:Dimension

an instance of Dimension that represents the preferred size of this container.

setCommandContextback to summary
public void setCommandContext(String verb, DataHandler dh) throws IOException

Implements javax.activation.CommandObject.setCommandContext.

Doc from javax.activation.CommandObject.setCommandContext.

Initialize the Command with the verb it is requested to handle and the DataHandler that describes the data it will operate on

Note

it is acceptable for the caller to pass null as the value for DataHandler.

Parameters
verb:String

The Command Verb this object refers to.

dh:DataHandler

The DataHandler.

Exceptions
IOException:
for failures accessing data
setInputStreamback to summary
public void setInputStream(InputStream ins) throws IOException
