TerPixToTextPos

Retrieve the text position at a given pixel position.

boolean TerPixToTextPos( RelativeTo, x, y, pCol)

`int RelativeTo;`	This parameter should be set to one of the following constants:
REL_SCREEN:	When specifying the x/y values relative to the top of the screen.
REL_WINDOW:	When specifying the x/y values relative to the client area of the edit control.
REL_TEXT_BOX:	When specifying the x/y values relative to the top of the text box.
`int x;`	The x position of the pixel.
`int y;`	The y position of the pixel.

// To retrieve the absolute text position in the pLine parameter, set the pCol parameter to null or set the column number to -1.

Upon a successful return from this method, the following information can be retrieved by using TerGetOutInt method:

int pLine;

Upon successful return from this method, the corresponding line number can be retrieved as following:

line=tej.TerGetOutInt("Line");

int pCol;

Upon successful return from this method, the corresponding line number can be retrieved as following:

col=tej.TerGetOutInt("Col");

Return Value: This function returns true when successful.

Example: The example below retrieves the text position at a pixel position x=100, y=100.

  int line;
  int col=0;      // set to 0 to retrieve the position in
                  // line/column format.
  if (TerPixToTextPos( tej.REL_TEXT_BOX, 100, 100, col)) {
    line=tej.TerGetOutInt("Line");
    col=tej.TerGetOutInt("Col");
