| Form Designer usage / Properties list | |
The windowStyle property defines the style to be used by the parent window of a form.
The windowStyle property can be used to specify the style of the parent window that will hold the form. This property is specific to the form. Do not confuse with the STYLE property, which is used to specify decoration style of the form elements.
When a form is loaded by the OPEN WINDOW or DISPLAY FORM instructions, the runtime system automatically assigns the windowStyle to the style property of the parent window element.
