_WGetCursorP( ) API Library Routine

  • Articolo

Returns in pixels the current output position in the specified window.

Point _WGetCursorP(WHANDLE wh)
WHANDLE wh;            /* Window handle. */

Remarks

For more information on how to create an API library and integrate it with Visual FoxPro, see Accessing the Visual FoxPro API.

Example

The following example creates a window and draws a diagonal pattern of Xs in this window. It positions the cursor before writing each X using _WPosCursorP( ), and gets that same position using _WGetCursorP( ).

Visual FoxPro Code

SET LIBRARY TO WGETCURP

C Code

#include <pro_ext.h>

void putLong(long n, int width)
{
   Value val;

   val.ev_type = 'I';
   val.ev_long = n;
   val.ev_width = width;

   _PutValue(&val);
}

FAR Example(ParamBlk FAR *parm)
{
   WHANDLE wh;
   Point putPos, getPos;

   wh = _WOpen(4,4,20,70,0,WINDOW_SCHEME,(Scheme FAR *)0,
      WO_SYSTEMBORDER);
   _WShow(wh);

   for (putPos.v = 10; putPos.v < 100; putPos.v += 10)
   {
      putPos.h = putPos.v;

      _WPosCursorP(wh, putPos);
      _WPutChr(wh, 'X');

      getPos = _WGetCursorP(wh);

      _PutStr("\nCursor position:");
      putLong(getPos.v, 5);
      putLong(getPos.h, 5);

      _Execute("WAIT");
   }
   _WClose(wh);
}

FoxInfo myFoxInfo[] = {
   {"ONLOAD", Example, CALLONLOAD, ""},
};
FoxTable _FoxTable = {
   (FoxTable FAR *) 0, sizeof(myFoxInfo)/sizeof(FoxInfo), myFoxInfo
};
