XmeFromVerticalPixels(3X) UNIX System V XmeFromVerticalPixels(3X)
NAME
XmeFromVerticalPixels - Converts from pixels to real-world
dimensions based on vertical resolution of the screen
SYNOPSIS
#include <Xm/XmP.h>
void XmeFromVerticalPixels(
Widget widget,
int offset,
XtArgVal *value);
VERSION
This page documents Motif 2.1.
DESCRIPTION
XmeFromVerticalPixels converts a vertical pixel value to a
real-world dimensional unit. The real-world dimensional unit
depends on the value of the XmNunitType resource associated
with the widget. For example, suppose widget has an
XmNunitType resource value of Xm1000TH_INCHES. If the input
value were 200 pixels, the output value might be 2500 (2.5
inches) on one screen and 2000 (2.0 inches) on another
screen.
XmeFromVerticalPixels is an XmExportProc.
Typically, your widgets will call this function in a
synthetic resource record.
widget Specifies the widget.
offset Specifies the offset in bytes of a synthetic
resource field in the widget record.
value Specifies a value in pixels and returns a value in
the dimensional units used by widget.
