    Remarks

    Items in a RelativeCanvas are placed relative to the RelativeCanvas itself. The following attached properties each have their use:

    • RelativeCanvas.Left (value >= 0): used to indicate where to place the item from left to right.
      • 0 = Extreme left
      • 1 = Extreme right
    • RelativeCanvas.Top (value >= 0): used to indicate where to place the item from top to bottom.
      • 0 = Complete top
      • 1 = Complete bottom
    • RelativeCanvas.RelativeWidth (value >= 0): used to indicate the width of the element relative to the width of the RelativeCanvas.
      • ex: a value of 0.5 will indicate that the element's width must be half the width of the RelativeCanvas
    • RelativeCanvas.RelativeHeight (value >= 0): used to indicate the height of the element relative to the height of the RelativeCanvas.
      • ex: a value of 0.5 will indicate that the element's height must be half the height of the RelativeCanvas
    • RelativeCanvas.PinPoint: reference point from which the other properties/characteristics will be calculated.
      • (0,0) -> Top left corner
      • (1,0) -> Top right corner
      • (0,1) -> Bottom left corner
      • (1,1) -> Bottom right corner

    This means that the attached properties RelativeCanvas.RelativeWidth and RelativeCanvas.RelativeHeight must be set on the elements that should have a size relative to the size of the RelativeCanvas.

    For elements that should have a fixed size, assign a value to FrameworkElement.Width and/or FrameworkElement.Height.

    For elements that should have a size in function of their content, do not specify anything.
