Package ej.mwt.style.dimension

Class FixedDimension

  • All Implemented Interfaces:
    Dimension
    public class FixedDimension
extends java.lang.Object
implements Dimension
    Dimension with fixed width and/or height.

    The width or height are stored as a char for heap optimization and therefore cannot exceed 65535.

      • FixedDimension

        public FixedDimension​(int width,
                      int height)
        Creates a fixed dimension with constraints.

        Widget.NO_CONSTRAINT can be used to relax constraint on one dimension (width or height).

        The given width and height are clamped between 0 and Character.MAX_VALUE.

        Parameters:
        width - the width.
        height - the height.

    • Method Detail

      • getWidth

        public int getWidth()
        Returns the width constraint.
        Returns:
        the width constraint, or Widget.NO_CONSTRAINT if there is no width constraint.

      • getHeight

        public int getHeight()
        Returns the height constraint.
        Returns:
        the height constraint, or Widget.NO_CONSTRAINT if there is no height constraint.

      • getAvailableSize

        public void getAvailableSize​(Widget widget,
                             int availableWidth,
                             int availableHeight,
                             Size availableSize)
        Description copied from interface: Dimension
        Gets the available size for a widget.

        The given available size is the available width and height minus the outlines.

        The given size is updated by this method to set the available size for this dimension.

        Specified by:
        getAvailableSize in interface Dimension
        Parameters:
        widget - the widget.
        availableWidth - the available width.
        availableHeight - the available height.
        availableSize - the available size.

      • computeOptimalSize

        public void computeOptimalSize​(Widget widget,
                               int availableWidth,
                               int availableHeight,
                               Size optimalSize)
        Description copied from interface: Dimension
        Computes the optimal size of a widget.

        The given optimal size is the optimal size of the widget considering the available size.

        The given size is updated by this method to set the optimal size for this dimension.

        Specified by:
        computeOptimalSize in interface Dimension
        Parameters:
        widget - the widget.
        availableWidth - the available width.
        availableHeight - the available height.
        optimalSize - the optimal size.

      • layOut

        public void layOut​(Widget widget,
                   Rectangle bounds)
        Description copied from interface: Dimension
        Lays out a widget.

        The style of the widget must be set before (not null).

        This dimension is applied to compute the widget bounds and align the widget in the given bounds. The given rectangle is updated with the updated bounds.

        Specified by:
        layOut in interface Dimension
        Parameters:
        widget - the widget.
        bounds - the bounds of the widget.
