IsMinimizable Attribute
Data Type: integer
4GL Access: RW1
Determines the state of the Minimize button in the title bar. Possible values are TRUE and FALSE.
A Minimize button is displayed in the title bar only if IsToolWindow is FALSE and both IsTitled and IsClosable are TRUE. When a Minimize button is displayed in the title bar, it is enabled if IsMinimizable is TRUE and disabled if IsMinimizable 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 statement.
