PowerBuilder Classic 12.1 has a new height property and a new height expression function for the DataWindow object. This property is only supported in PowerBuilder Native. It is not supported in Windows Forms, Web Forms, or PowerBuilder .NET. HasMinHeight only applies to columns that have Autosize enabled. When both Autosize height and HasMinHeight are true, the height value will be the max value between the auto height value (the calculated value when the Autosize height is set to true) and the value specified in the Height property. For example:
dw_1.object.fname.Height.HasMinHeight = "no"
dw_1.object.compute_1.Height.HasMinHeight = "yes"
dw_1.object.t_1.Height.HasMinHeight = "no"
