XmSetFontUnit — A function that sets the font unit value for a display "XmSetFontUnit"

#include <Xm/Xm.h>
void XmSetFontUnit(
Display * display,
int font_unit_value);

XmSetFontUnit provides an external function to initialize font unit values. Applications may want to specify resolution-independent data based on a global font size. See the XmNunitType resource description in the reference pages for XmGadget, XmManager, and XmPrimitive for more information on resolution independence.

This function sets the font units for all screens on the display.

NOTE: XmSetFontUnit is obsolete and exists for compatibility with previous releases. Instead of using this function, provide initial values or call XtSetValues for the XmScreen resources XmNhorizontalFontUnit and XmNverticalFontUnit.

Defines the display for which this font unit value is to be applied.
Specifies the value to be used for both horizontal and vertical font units in the conversion calculations.
