ARC( x ,y ,width ,height ,startangle ,endangle [,attributelist] )
| ARC | Draws an arc of an ellipse on the current window or report. |
| X | An integer expression that specifies the horizontal position of the starting point. |
| Y | An integer expression that specifies the vertical position of the starting point. |
| Width | An integer expression that specifies the width. |
| Height | An integer expression that specifies the height. |
| startangle | An integer expression that specifies the starting point of the arc, in tenths of degrees (10 = 1 degree) measured counter-clockwise from three o'clock. |
| endangle | An integer expression that specifies the ending point of the arc, in tenths of degrees (10 = 1 degree) measured counter-clockwise from three o'clock. |
| attributelist | A string constant, variable, or EQUATE containing an optional type of output document and its associated attributes. Only valid when the target is a REPORT. See EXTEND |
The ARC procedure places an arc of an ellipse on the current target. This procedure is valid in Clarion Win32 Windows, and also for REPORT structures in both Clarion Win32 and Clarion#. The ellipse is drawn inside a “bounding box” defined by the x, y, width, and height parameters. The x and y parameters specify the starting point, and the width and height parameters specify the horizontal and vertical size of the “bounding box.”
The startangle and endangle parameters specify what sector of the ellipse will be drawn, as an arc.
The border color is the current pen color set by SETPENCOLOR; the default color is the Windows system color for window text. The border width is the current width set by SETPENWIDTH; the default width is one pixel. The border style is the current pen style set by SETPENSTYLE; the default style is a solid line.
Example:
MDIChild WINDOW('Child One'),AT(0,0,320,200),MDI,MAX,HVSCROLL
!window controls
