Syntax

Drawing a rectangle by specifying the coordinates of rectangle Hide the details

<Image control>.DrawRectangle(<X1> , <Y1> , <X2> , <Y2> [, <Background> [, <Line>]])
<Image control>: Control name
Name of the Image control to be used.
<X1>: Integer
X-coordinate (in pixels) of the upper-left corner of the rectangle.
<Y1>: Integer
Y-coordinate (in pixels) of the upper-left corner of the rectangle.
<X2>: Integer
X-coordinate (in pixels) of the lower-right corner of the rectangle.
<Y2>: Integer
Y-coordinate (in pixels) of the lower-right corner of the rectangle.
<Background>: Integer, constant or Background variable (optional)
  • Background color of rectangle. This color can be:
  • Background characteristics:
    • WINDEVWEBDEV - Server codeUniversal Windows 10 AppiPhone/iPadIOS WidgetMac Catalyst variable of type Background. In this case, the gradient defined in the variable is ignored.
      Android Background variables are not available in this syntax. Use <Image>.DrawBorder to customize the background color.
    • characteristics specified in the last call to <Image>.Background if this parameter is not specified.
To use a gradient background color, call <Image>.DrawRectangleGradient.
<Line>: Integer, constant or Border variable (optional)
  • Color of rectangle line. This color can be:
    • an RGB color (returned by RGB),
    • an HSL color (returned by HSL),
    • a WLanguage preset color,
    • WINDEVWEBDEV - Server codeUniversal Windows 10 AppiPhone/iPadIOS WidgetMac Catalyst a variable of type Color,
    • identical to the color used for the background if this parameter is not specified and if <Image>.Pen has not been used.
  • Characteristics of the line:
    • WINDEVWEBDEV - Server codeiPhone/iPadIOS WidgetMac Catalyst variable of type Border. In this case, only the following properties are taken into account:
      • Color: if the property is set to ColorUndefined, the color defined in the last call to <Image>.Pen is used. If this function has not been used, the background color of the rectangle will be used.
      • Thickness: if the property is set to ThicknessUndefined, the thickness defined in the last call to <Image>.Pen is used. If this function has not been used, the thickness will be set to 1.
      • Line: if the property is set to LineUndefined, the type of line defined in the last call to <Image>.Pen is used. If this function has not been used, the line will be solid.
    • characteristics specified in the last call to <Image>.Pen if this parameter is not specified.
