Layer position of an object. When two objects overlap, WdgZOrder specifies the order in which they are “layered”. The object with the higher or highest number is on “top”.
Valid Values
An integer
Remarks
The Structure Chart of the Screen Painter displays the relative Z-order of all objects in the form or display.
The Z-order of an object can be changed by dragging the object from its current position in the structure to a new position and releasing it.
FObjects closer to the bottom of the Structure Chart are displayed on top of objects closer to the top of the Chart.
The form’s sequence number in a display. A user-assigned number that can be used to control the tabbing sequence within the forms of a display.
Valid Values
An integer (0 to 999).
Remarks
If FSN is set to 0, the software automatically resets it to match the Z-order (WdgZOrder) specified for the form. Accordingly, if all forms in a display are painted with FSNs of 0, then the Painter’s structure diagram automatically defines the tab order when WINDOW SET TABORDER BY TABINDEX is in effect. (BY TABINDEX is the default setting for graphic-class windows.)
