This example Queries the Bidirectional Attributes of the presentation space, modifed the BDA_TEXTTYPE parameter and sets the new value to be the new bidirectional attributes word of the presentation space.
#define INCL_PMBIDI #include <OS2.H> #include <PMBIDI.H> VOID SetBidiAttr(VOID) { HPS hps; ULONG ulBidiAttr; ULONG fSuccess; hps = WinGetPS(hwnd); if (hps) ulBidiAttr = GpiQueryBidiAttr (hps); ulBidiAttr &= ~BDAM_TEXTTYPE; ulBidiAttr |= BDA_TEXTTYPE_VISUAL; fSuccess = GpiSetBidiAttr (hps, ulBidiAttr); WinReleasePS(hps); }
