MIN-BUTTON attribute

Determines whether the window has a minimize button in its caption bar.

Data type: LOGICAL

Access: Readable/Writeable

Applies to: WINDOW widget

In Windows, a window can have maximize and minimize buttons depending on the settings of the MIN-BUTTON and MAX-BUTTON attributes. Both buttons are created on the window. If you set the MIN-BUTTON to TRUE and the MAX-BUTTON to FALSE, only the MIN-BUTTON is enabled; the MAX-BUTTON is disabled.

The MIN-BUTTON attribute must be set before the window is realized. The default value is TRUE.

On character platforms, this attribute has no effect.
