Many Built-in subprograms allow you to specify size and position coordinates, using properties such as:
When you specify coordinates or width and height, you express these measurements in units of the current form coordinate system, set on the Form Module property sheet. The form coordinate system defines the units for specifying size and position coordinates of objects in Oracle Forms. Use the Coordinate System form module property to set the form's coordinate units:
When you design in the character cell coordinate system, all object dimensions and position coordinates are expressed in character cells, so Oracle Forms accepts only whole numbers for size and position properties.
When you design using real units (inches, centimeters, or points), all object dimensions and position coordinates are expressed in the units you specify, so Oracle Forms will accept decimals as well as whole numbers for size and position properties. The precision of real units is three digits, so you can specify coordinates to thousandths. If you use pixels or character cells, coordinates are truncated to whole numbers.
