DtkshUnder, DtkshOver, DtkshRightOf, and DtkshLeftOf

These convenience functions simplify the specification of certain classes of form constraints. They provide a way of attaching a component to one edge of another component. They are used when constructing the resource list for a widget. This behavior is accomplished using the ATTACH_WIDGET constraint.

Usage:

DtkshUnder widgetId [offset]  
DtkshOver widgetId [offset] 
DtkshRightOf widgetId [offset]  
DtkshLeftOf widgetId [offset]

The widgetId parameter specifies the widget to which the current component is to be attached. The offset value is optional and defaults to 0 if not specified.

Example:

XtCreateManagedWidget BUTTON4 button4 XmPushButton $FORM \    
     labelString:"Exit" \
     $(DtkshUnder $BUTTON2) \
     $(DtkshRightOf $BUTTON3)
