描述
clear_rectangleclear_rectangleClearRectangleClearRectangleClearRectangleclear_rectangle deletes all entries in the rectangle which
is defined through the upper left corner
(Row1Row1Row1Row1row1row_1,Column1Column1Column1Column1column1column_1) and the lower right corner
(Row2Row2Row2Row2row2row_2,Column2Column2Column2Column2column2column_2). Deletion means that the
specified rectangle is set to the background color (see
open_windowopen_windowOpenWindowOpenWindowOpenWindowopen_window).
If you want to delete more than one rectangle, you may pass several
rectangles, i.e., the parameters Row1Row1Row1Row1row1row_1, Column1Column1Column1Column1column1column_1,
Row2Row2Row2Row2row2row_2 and Column2Column2Column2Column2column2column_2 are tuples.
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。

示例（HDevelop）
* Erase a rectangle in the output window interactively:
draw_rectangle1(WindowHandle,L1,C1,L2,C2)
示例（C）
/* Erase a rectangle in the output window interactively: */
draw_rectangle1(WindowHandle,&L1,&C1,&L2,&C2);
示例（HDevelop）
* Erase a rectangle in the output window interactively:
draw_rectangle1(WindowHandle,L1,C1,L2,C2)
示例（HDevelop）
