Name
draw_rectangle1draw_rectangle1DrawRectangle1DrawRectangle1 — Draw a rectangle parallel to the coordinate axis.
draw_rectangle1draw_rectangle1DrawRectangle1DrawRectangle1DrawRectangle1 returns the parameter for a rectangle parallel
to the coordinate axes, which has been created interactively by the user
in the window.
To create a rectangle you have to press the left mouse button determining a corner
of the rectangle. While keeping the button pressed you may “drag” the rectangle in
any direction. After another mouse click in the middle of the created rectangle
you can move it.
A click close to one side “grips” it to modify the rectangle's dimension in perpendicular
direction to this side. If you click on one corner of the created rectangle, you may
move this corner.
Pressing the right mouse button terminates the procedure. On macOS
draw_rectangle1draw_rectangle1DrawRectangle1DrawRectangle1DrawRectangle1 can also be terminated by pressing the escape key.
After terminating the procedure the rectangle is not visible in the window any longer.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
