XmScrollVisible — A ScrolledWindow function that makes an
invisible
descendant of a ScrolledWindow work area visible
#include <Xm/ScrolledW.h>
void XmScrollVisible(
Widget scrollw_widget,
Widget widget,
Dimension left_right_margin,
Dimension top_bottom_margin);
XmScrollVisible makes an obscured or partially obscured widget or gadget
descendant of a ScrolledWindow work area visible. The function repositions 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.
