NOMAXIMIZE Property
Enable or disable the capability to maximize the Window
Description:
The NOMAXIMIZE Property can be used to turn a Window's maximize button and system menu MAXIMIZE option on or off
The image below demonstrates a Window with the NOMAXIMIZE property set to true(.T.). Note that maximize button between to the Minimize and Close buttons is greyed out. The MAXIMIZE option on the system menu is also disabled
Syntax:
THISWINDOW | <FormName>.NOMAXIMIZE --> lValue
THISWINDOW | <FormName>.NOMAXIMIZE := lValue
Valid For Use With:
This Property is assumed to be available for use with all Window types
Notes:
This property is only available after Window definition
It is one of the newer properties which is intended to overcome a limitation with the MAXBUTTON property which can only be used during Window definition
Important: The values used or returned by THISWINDOW | <FormName>.NOMAXIMIZE can easily be misunderstood!
Firstly, when you change the value the old value is not returned
Secondly, when you need to change the value (either turn the maximize button on or off), you do use the value that you would expect. Eg. to turn the maximize button off, you would use THISWINDOW | <FormName>.NOMAXIMIZE := .T.
Finally, note that the value returned when using THISWINDOW | <FormName>.NOMAXIMIZE appears to be the opposite of the value that you would expect. so if you run THISWINDOW | <FormName>.NOMAXIMIZE := .T. and then run THISWINDOW | <FormName>.NOMAXIMIZE the value returned is actually .F.!
