disp_circleT_disp_circleDispCircleDispCircledisp_circle (算子名称)

名称

disp_circleT_disp_circleDispCircleDispCircledisp_circle — Displays circles in a window.

参数签名

disp_circle( : : WindowHandle, Row, Column, Radius : )

描述

disp_circledisp_circleDispCircleDispCircleDispCircledisp_circle displays one or several circles in the output window. A circle is described by the center (RowRowRowRowrowrow, ColumnColumnColumnColumncolumncolumn) and the radius RadiusRadiusRadiusRadiusradiusradius. If the used coordinates are not within the window the circle is clipped accordingly.

该算子s used to control the display of regions (e.g., set_drawset_drawSetDrawSetDrawSetDrawset_draw, set_grayset_graySetGraySetGraySetGrayset_gray, set_drawset_drawSetDrawSetDrawSetDrawset_draw) can also be used with circles. Several circles can be displayed with one call by using tuple parameters. For the use of colors with several circles, see set_colorset_colorSetColorSetColorSetColorset_color.

注意

The center of the circle must be within the window.

例程 (HDevelop)

open_window(0,0,-1,-1,'root','visible','',WindowHandle)
set_draw(WindowHandle,'fill')
set_color(WindowHandle,'white')
repeat
  get_mbutton(WindowHandle,Row,Column,Button)
  disp_circle(WindowHandle,Row,Column,(Row + Column) % 50)
until(Button == 1)
close_window(WindowHandle)

结果

disp_circledisp_circleDispCircleDispCircleDispCircledisp_circle returns 2 ( H_MSG_TRUE) .
