org.ka2ddo.yaac.gui.terminal.Terminal
public final class Terminal
This class implements a simple Terminal window to access interface ports for debugging. It opens input and output streams to the specified device (Internet socket or RXTX serial device), interprets the bytes from the input stream as ISO-8859-1 characters (including control characters) to display, and accepts user input from the keyboard and sends it to the output stream (optionally locally echoing the entered characters to the screen). The screen implements a simple emulation of a DEC VT102 screen. It will be 24 lines tall and either 80 or 132 characters wide. The screen maintains positional and escape sequence context state from the input characters.

public void validate()
The validate
method is used to cause a container
to lay out its subcomponents again. It should be invoked when
this container's subcomponents are modified (added to or
removed from the container, or layout-related information
changed) after the container has been displayed.
If this Container
is not valid, this method invokes
the validateTree
method and marks this Container
as valid. Otherwise, no action is performed.

events may not be delivered during a native
Drag and Drop operation.
