Data Type: integer

4GL Access: RW1

Determines the state of the Maximize button in the title bar. Possible values are TRUE and FALSE.

A Maximize button is displayed in the title bar only if IsToolWindow is FALSE and both IsTitled and IsClosable are TRUE. When a Maximize button is displayed in the title bar, it is enabled if IsMaximizable is TRUE and disabled if IsMaximizable is FALSE.

You can set this attribute only before the frame is realized, either by setting it in the Frame Editor or by setting the attribute in the with clause of a callframe or openframe statement, or by setting it in the frame's initialize procedure.
