windowStyle
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.
For additional information, see the WINDOWSTYLE attribute topic in the Genero Business Development Language User Guide.
