Description

draw_line_moddraw_line_modDrawLineModdraw_line_modDrawLineModDrawLineMod returns the parameter for a line, which has been created interactively by the user in the window.

To create a line are expected the coordinates of the start point Row1InRow1InRow1InRow1InRow1Inrow1In, Column1InColumn1InColumn1InColumn1InColumn1Incolumn1In and of the end point Row2InRow2InRow2InRow2InRow2Inrow2In,Column2InColumn2InColumn2InColumn2InColumn2Incolumn2In. If you click on one end point of the created line, you may move this point. After another mouse click in the middle of the created line you can move it.

Pressing the right mouse button terminates the procedure. On macOS draw_line_moddraw_line_modDrawLineModdraw_line_modDrawLineModDrawLineMod can also be terminated by pressing the escape key.

After terminating the procedure the line is not visible in the window any longer.
