Description

draw_rectangle1_moddraw_rectangle1_modDrawRectangle1ModDrawRectangle1ModDrawRectangle1Mod 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 are expected the parameters Row1InRow1InRow1InRow1Inrow1In, Column1InColumn1InColumn1InColumn1Incolumn1In,Row2InRow2InRow2InRow2Inrow2In and Column2InColumn2InColumn2InColumn2Incolumn2In. After a 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_rectangle1_moddraw_rectangle1_modDrawRectangle1ModDrawRectangle1ModDrawRectangle1Mod can also be terminated by pressing the escape key.

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

Result

draw_rectangle1_moddraw_rectangle1_modDrawRectangle1ModDrawRectangle1ModDrawRectangle1Mod returns 2 (H_MSG_TRUE), if the window is valid and the needed drawing mode (see set_insertset_insertSetInsertSetInsertSetInsert) is available. If necessary, an exception is raised.
