ShowControl

Make a control visible; draw it if not obscured

#include <Controls.h> Control Manager

void ShowControl(theControl );

ControlHandle theControl ; control to draw

ShowControl sets the control's contrlVis field to 255 and immediately

draws the control (if it is not obscured by an overlapping window, an other

control, or other object).

theControl is a handle leading to a variable-length ControlRecord structure. It

identifies which control you wish to draw.

Notes: ShowControl undoes the effect of HideControl. It draws whatever

portion of the control is on-screen (and unobscured) and makes the control

logically visible so that DrawControls, Draw1Control and

UpdtControl will cause it to be drawn.

Note that when controls overlap, the most-recently created control is

considered to be in front. If theControl is behind another visible control,

ShowControl may not draw it.
