XmDirectionMatch(3) Library Functions Manual XmDirectionMatch(3) NAME XmDirectionMatch -- A function that checks for a specified direction component SYNOPSIS #include <Xm/Xm.h> Boolean XmDirectionMatch (d1, d2) XmDirection d1; XmDirection d2; (void) DESCRIPTION XmDirectionMatch compares two XmDirection values. The function returns a Boolean value depending on whether or not the two input values "match." The simplest match is when d1 and d2 are identical. However, other matches are possible. XmDirectionMatch attempts to compare spec- ified bits only; nonspecified bits automatically match. For example, suppose that d1 equals XmTOP_TO_BOTTOM_RIGHT_TO_LEFT. In this case, the function will return True if d2 equals either Xm- RIGHT_TO_LEFT or XmTOP_TO_BOTTOM. However, the function will return False if d2 equals XmTOP_TO_BOTTOM_LEFT_TO_RIGHT, XmBOT- TOM_TO_TOP_RIGHT_TO_LEFT, or XmBOTTOM_TO_TOP_LEFT_TO_RIGHT. Note that direction can be thought of as having three components, a horizontal component, a vertical component, and the precedence among them. This means that in addition to the previously mentioned direc- tions, the function will still return False if d1 equals XmTOP_TO_BOT- TOM_RIGHT_TO_LEFT and d2 equals XmRIGHT_TO_LEFT_TOP_TO_BOTTOM. d1 Specifies an XmDirection value. d2 Specifies an XmDirection value. RETURN VALUES Returns True if d1 "matches" d2; otherwise, returns False.
