XmConvertUnits(library call) XmConvertUnits(library call) NAME
XmConvertUnits -- A function that converts a value in one unit type to another unit type SYNOPSIS
#include <Xm/Xm.h> int XmConvertUnits( Widget widget, int orientation, int from_unit_type, int from_value, int to_unit_type); DESCRIPTION
XmConvertUnits converts the value and returns it as the return value from the function. For resources of type, dimension, or position, you can specify units using the syntax described in the XmNunitType resource of the XmPrimitive reference page. widget Specifies the widget for which the data is to be converted. orientation Specifies whether the converter uses the horizontal or vertical screen resolution when performing the conversions. The orienta- tion parameter can have values of XmHORIZONTAL or XmVERTICAL. from_unit_type Specifies the current unit type of the supplied value from_value Specifies the value to be converted to_unit_type Converts the value to the unit type specified The parameters from_unit_type and to_unit_type can have the following values: XmPIXELS All values provided to the widget are treated as pixel values. This is the default for the resource. XmMILLIMETERS All values provided to the widget are treated as millimeter values. Xm100TH_MILLIMETERS All values provided to the widget are treated as 1/100 of a millimeter. XmCENTIMETERS All values provided to the widget are treated as centimeter values. XmINCHES All values provided to the widget are treated as inch values. Xm1000TH_INCHES All values provided to the widget are treated as 1/1000 of an inch. XmPOINTS All values provided to the widget are treated as point values. A point is a unit used in text processing applications and is defined as 1/72 of an inch. Xm100TH_POINTS All values provided to the widget are treated as 1/100 of a point. A point is a unit typically used in text processing applica- tions and is defined as 1/72 of an inch. XmFONT_UNITS All values provided to the widget are treated as normal font units. A font unit has horizontal and vertical components. These are the values of the XmScreen resources XmNhorizontalFontUnit and XmNverticalFontUnit. Xm100TH_FONT_UNITS All values provided to the widget are treated as 1/100 of a font unit. A font unit has horizontal and vertical components. These are the values of the XmScreen resources XmNhorizontalFontUnit and XmNverticalFontUnit. RETURN
Returns the converted value. If a NULL widget, incorrect orientation, or incorrect unit_type is supplied as parameter data, 0 (zero) is returned. RELATED

XmConvertStringToUnits -- A function that converts a string specification to a unit value SYNOPSIS
#include <Xm/Xm.h> int XmConvertStringToUnits( Screen *screen, String spec, int orientation, int to_type, XtEnum *parse_error); DESCRIPTION
XmConvertStringToUnits converts a string specification value and returns the converted value as the return value from the function. This function uses the specified screen's resolution to compute the number of units for the string specification. screen Specifies the screen whose resolution is to be used for the computation. spec Specifies the string, in <floating value><unit> format, to be converted. orientation Specifies whether the converter uses the horizontal or vertical screen resolution when performing the conversion. The orientation parameter can have values of XmHORIZONTAL or XmVERTICAL. to_type Converts the value to the unit type specified. Refer to the XmNunitType resource of the XmGadget, XmManager, or XmPrimitive ref- erence page. This parameter can have one of the following values: XmPIXELS The returned value will be the number of pixels. XmMILLIMETERS The returned value will be the number of millimeters. Xm100TH_MILLIMETERS The returned values will be the number of 1/100 millimeters. XmCENTIMETERS The returned values will be the number of centimeters. XmINCHES The returned values will be the number of inches. Xm1000TH_INCHES The returned values will be the number of 1/100 inches. XmPOINTS The returned values will be the number of points. A point is a text processing unit defined as 1/72 of an inch. Xm100TH_POINTS The returned values will be the number of 1/100 points. XmFONT_UNITS All values provided to the widget are treated as font units. A font unit has horizontal and vertical components. These are the values of the XmScreen resources XmNhorizontalFontUnit and XmNverticalFontUnit. Xm100TH_FONT_UNITS All values provided to the widget are treated as 1/100 of a font unit. A font unit has horizontal and vertical compo- nents. These are the values of the XmScreen resources XmNhorizontalFontUnit and XmNverticalFontUnit. parse_error Specifies if a parsing error occurred. This is set to a value of True indicates that an error occurred, a value of False to indi- cate no error. RETURN
Returns the converted value. If a NULL screen, incorrect orientation, or incorrect unit_type is supplied as parameter data, or if a pars- ing error occurred, 0 (zero) is returned. RELATED
