Programmatic control of the command window

| Watch this File

File Information

Programmatic control of the the command window
On a netbook with a tiny monitor, the toolbar and the statusbar of Matlab's
command window occupy valuable space. The function CmdWinTool uses
undocumented Java methods to hide these UI elements.
But the interface allows much more:
Reply = CmdWinTool(Command, Data)
  Command as string:
  lean, fat: Hide or show toolbar and statusbar
  title: Set and get the window title
  statusText: String in the statusbar at the bottom
  toFront, toBack: Window before of behind other windows.
  hide, show: Hide or show the window
  JPosition: Set/get position relative to virtual screen, java conventions
  Position: Set/get position relative to monitor (*), Matlab conventions
  maximize, minimize, restore: guess...
  xmax, ymax: maximize horizontally/vertically only (*)
  toScreen: Move completely to nearest monitor (*)
  getHWnd: Get OS handle of the window (Windows only?)
  setFocus: Gain keyboard focus (*)
  getText: Get text written to window.
  top: Set AlwaysOnTop property
  font: Set and get font name and size
  background, foreground: Set and get font and background color
  isBusy: TRUE if a program is running

The commands marked with (*) run under Windows only and need WindowAPI:
The other commands should run under MacOS and Linux also.
Tested: Matlab 6.5, 2008b, 2009a, 2011b, WinXP, Win7, multi-monitors
Run uTest_CmdWinTool to check compatibility on your platform.
I'd appreciate bugreports and suggestions for improvements.

This function is inspired by Yair Altman's excellent investigations in the
secrets of Matlab. See
