Description

disp_circledisp_circledisp_circleDispCircleDispCircle displays one or several circles in the output window. A circle is described by the center (RowRowRowRowrow, ColumnColumnColumnColumncolumn) and the radius RadiusRadiusRadiusRadiusradius. If the used coordinates are not within the window the circle is clipped accordingly.

The operators used to control the display of regions (e.g. set_drawset_drawset_drawSetDrawSetDraw, set_grayset_grayset_graySetGraySetGray, set_drawset_drawset_drawSetDrawSetDraw) 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_colorset_colorSetColorSetColor.

Attention

The center of the circle must be within the window.

Example (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)

Example (C)

open_window(0,0,-1,-1,"root","visible","",&WindowHandle) ;
set_draw(WindowHandle,"fill") ;
set_color(WindowHandle,"white") ;
get_mbutton(WindowHandle,&Row,&Column,&Button) ;
disp_circle(WindowHandle,Row,Column,(Row + Column) mod 50) ;

Example (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)
