MinButton Property
This property determines whether or not an object has a "minimise" button. Pressing this button will cause the object to be iconified. Pressing it again will restore the object to its original size. MinButton is a single number with the value 0 (no minimise button) or 1 (minimise button is provided). The default is 1.
Note that MinButton is independent of Sizeable, that is, you can define an object that can be minimised but not resized.
If any of the properties MinButton, MaxButton, SysMenu, and Moveable are set to 1, the object will have a title bar.
If either MinButton or MaxButton is 1, then HelpButton is always hidden, irrespective of its value. This is a Microsoft Windows limitation.
