Description
The FORM SET VERTICAL RESIZING command allows you to change the vertical resizing properties of the current form through programming. By default, these properties are set in the Design environment Form editor. New properties are set for the current process; they are not stored with the form.
The resize parameter lets you set whether the form can be resized vertically; in other words, if the height can be changed (manually by the user or through programming).
If you pass True, the form height can be modified by the user; 4D uses values passed in minHeight and maxHeight as markers.
If you pass False, the current form height cannot be changed; in this case, there is no need to pass values in the minHeight and maxHeight parameters.
If you passed True in the first parameter, you can pass new minimum and maximum heights (in pixels) in the optional minHeight and maxHeight parameters. If you leave these parameters out, the values set in the Design environment (if any) are used.
