SYNOPSIS

10       #include <Xm/Xm.h>
11       int XmConvertStringToUnits(
12       Screen *screen,
13       String spec,
14       int orientation,
15       int to_type,
16       XtEnum *parse_error);

DESCRIPTION

19       XmConvertStringToUnits  converts  a  string  specification  value   and
20       returns  the  converted  value  as  the return value from the function.
21       This function uses the specified screen's  resolution  to  compute  the
22       number of units for the string specification.
23
24       screen    Specifies  the  screen whose resolution is to be used for the
25                 computation.
26
27       spec      Specifies the string, in <floating value><unit> format, to be
28                 converted.
29
30       orientation
31                 Specifies whether the converter uses the horizontal or verti‐
32                 cal screen resolution when  performing  the  conversion.  The
33                 orientation  parameter  can  have  values  of XmHORIZONTAL or
34                 XmVERTICAL.
35
36       to_type   Converts the value to the unit type specified.  Refer to  the
37                 XmNunitType  resource of the XmGadget, XmManager, or XmPrimi‐
38                 tive reference page.  This parameter can have one of the fol‐
39                 lowing values:
40
41                 XmPIXELS  The returned value will be the number of pixels.
42
43                 XmMILLIMETERS
44                           The  returned  value will be the number of millime‐
45                           ters.
46
47                 Xm100TH_MILLIMETERS
48                           The returned values will be  the  number  of  1/100
49                           millimeters.
50
51                 XmCENTIMETERS
52                           The  returned values will be the number of centime‐
53                           ters.
54
55                 XmINCHES  The returned values will be the number of inches.
56
57                 Xm1000TH_INCHES
58                           The returned values will be  the  number  of  1/100
59                           inches.
60
61                 XmPOINTS  The  returned  values will be the number of points.
62                           A point is a text processing unit defined  as  1/72
63                           of an inch.
64
65                 Xm100TH_POINTS
66                           The  returned  values  will  be the number of 1/100
67                           points.
68
69                 XmFONT_UNITS
70                           All values provided to the widget  are  treated  as
71                           font units. A font unit has horizontal and vertical
72                           components.  These are the values of  the  XmScreen
73                           resources  XmNhorizontalFontUnit  and  XmNvertical‐
74                           FontUnit.

76                 Xm100TH_FONT_UNITS
77                           All values provided to the widget  are  treated  as
78                           1/100  of  a font unit.  A font unit has horizontal
79                           and vertical components.  These are the  values  of
80                           the  XmScreen  resources  XmNhorizontalFontUnit and
81                           XmNverticalFontUnit.
82
83       parse_error
84                 Specifies if a parsing error occurred. This is set to a value
85                 of True indicates that an error occurred, a value of False to
86                 indicate no error.
87

RETURN

89       Returns the converted value.  If a NULL screen, incorrect  orientation,
90       or  incorrect  unit_type is supplied as parameter data, or if a parsing
91       error occurred, 0 (zero) is returned.
