Window decorations are set by the -dec switch on window allocation commands, e.g. wgraphic, wpanel etc.
The typical situation is to set decorations on/off by -dec or -no_dec, but a finer level of control is available for the appearance and behavior of individual facilities by setting -dec=<n> where n has a value greater than 1 and is a combination of values as follows:
Value
Details
0
Show no window decoration at all. This may also be specified by -no_dec
1
Show all window decoration. This may also be specified by -dec, or by omitting the -dec switch altogether.
+2
Enable the Close facility, allowing the window to be closed by user action.
+4
Enable the Minimize facility, allowing the window to be iconized by user action.
+8
Enable the Maximize facility, allowing the window to be resized to full-screen by user action.
+16
Display the title bar. This will be displayed irrespective, if any of the other buttons are enabled.
+32
Enable the Resize facility, allowing the window to be resized. Suppression of this also suppresses the Maximize facility. See Resize Note below.
+64
Enable the Move facility. Without this the window cannot be moved by user action.
Resize Note: The window resizing facility can also be set by the -fix/no_fix switch. This will override any resize increment (+32) specified in the decoration value. If the -fix/no_fix switch is omitted, and the decoration value is 1 or 0, the default resizing capability will depend on the window type, e.g. graphic, panel etc.
