XmScrollVisible(library call) XmScrollVisible(library call)
NAME
XmScrollVisible -- A ScrolledWindow function that makes an invisible
descendant of a ScrolledWindow work area visible
SYNOPSIS
#include <Xm/ScrolledW.h>
void XmScrollVisible(
Widget scrollw_widget,
Widget widget,
Dimension left_right_margin,
Dimension top_bottom_margin);
DESCRIPTION
XmScrollVisible makes an obscured or partially obscured widget or gadget descendant of a ScrolledWindow work area visible. The function re-
positions the work area and sets the specified margins between the widget and the nearest viewport boundary. The widget's location relative
to the viewport determines whether one or both of the margins must be adjusted. This function requires that the XmNscrollingPolicy of the
ScrolledWindow widget be set to XmAUTOMATIC.
scrollw_widget
Specifies the ID of the ScrolledWindow widget whose work area window contains an obscured descendant.
widget Specifies the ID of the widget to be made visible.
left_right_margin
Specifies the margin to establish between the left or right edge of the widget and the associated edge of the viewport. This
margin is established only if the widget must be moved horizontally to make it visible.
top_bottom_margin
Specifies the margin to establish between the top or bottom edge of the widget and the associated edge of the viewport. This
margin is established only if the widget must be moved vertically to make it visible.
