Articolo
06/18/2008

Fills in pt with the current position of the mouse pointer.

int _MousePos(Point FAR *pt)
Point FAR *pt;               /* Pointer. */

Remarks

_MousePos( ) returns True (an integer other than 0) if the left mouse button is down when the function is called, or False (0) if the left mouse button isn't down.

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 displays the current mouse pointer position until it detects a left mouse button click.

Visual FoxPro Code

SET LIBRARY TO MOUSEPOS

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 MousePosEx(ParamBlk FAR *parm)
{
   Point mousePos;

   while (!_MousePos(&mousePos))
   {
      _PutStr("\nvertical =");
      putLong(mousePos.v, 5);
      _PutStr("; horizontal =");
      putLong(mousePos.h, 5);
   }
}

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