XmeFromHorizontalPixels(3XUNIX System XmeFromHorizontalPixels(3X)
NAME
XmeFromHorizontalPixels - Converts from pixels to real-world
dimensions based on horizontal resolution of the screen
SYNOPSIS
#include <Xm/XmP.h>
void XmeFromHorizontalPixels(
Widget widget,
int offset,
XtArgVal *value);
VERSION
This page documents Motif 2.1.
DESCRIPTION
XmeFromHorizontalPixels converts a horizontal 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.
XmeFromHorizontalPixels 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.
