QUESTION
 How can I cause a window to be opened maximized?

ANSWER
 There is no way to truly maximize a window through code in VisualAge.
 Depending on your needs, it isn't difficult to make a window very large to
 approximate a maximized window. Windows are byte aligned and for
 some reason PM won't let you get any closer to the left edge than 4.

 In a script, you can send the Window the messages x:, y:, width:,
 and height:. CgScreen>>default can also be sent width: and height: to
 determine the size of the screen. If you set the window's x and y
 to 0 and set the width and height to the default screen's width and
 height minus some constant, you can approximate a maximized window.

 The best way to handle this is in a script. Connect the aboutToOpenWidget
 event of the window to the following script:

   (self subpartNamed: 'Window') yourself primaryWidget
     width: (CgScreen default width);
        height: (CgScreen default height).

 The window won't actually be in a maximized state, but it will be
 as large as your display (ie. device independent).
