draw_line_modT_draw_line_modDrawLineModDrawLineMod — Draw a line.
void DrawLineMod(const HTuple& WindowHandle, const HTuple& Row1In, const HTuple& Column1In, const HTuple& Row2In, const HTuple& Column2In, HTuple* Row1, HTuple* Column1, HTuple* Row2, HTuple* Column2)
void HWindow::DrawLineMod(double Row1In, double Column1In, double Row2In, double Column2In, double* Row1, double* Column1, double* Row2, double* Column2) const
static void HOperatorSet.DrawLineMod(HTuple windowHandle, HTuple row1In, HTuple column1In, HTuple row2In, HTuple column2In, out HTuple row1, out HTuple column1, out HTuple row2, out HTuple column2)

draw_line_moddraw_line_modDrawLineModDrawLineModDrawLineMod 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
Row1InRow1InRow1InRow1Inrow1In, Column1InColumn1InColumn1InColumn1Incolumn1In and of the end point
Row2InRow2InRow2InRow2Inrow2In,Column2InColumn2InColumn2InColumn2Incolumn2In.
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_modDrawLineModDrawLineModDrawLineMod can also be terminated by pressing the escape key.
After terminating the procedure the line is not visible in the window any longer.
If used in a buffer window, mouse events have to be supplied by the
application, while the draw operator must be run in another thread.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
