      public Grid(ContainerWrapper container, LC lc, AC rowConstr, AC colConstr, Map<? extends ComponentWrapper,CC> ccMap, ArrayList<LayoutCallback> callbackList)
      Constructor.
      Parameters:
      container - The container that will be laid out.
      lc - The form flow constraints.
      rowConstr - The rows specifications. If more cell rows are required, the last element will be used for when there is no corresponding element in this array.
      colConstr - The columns specifications. If more cell rows are required, the last element will be used for when there is no corresponding element in this array.
      ccMap - The map containing the parsed constraints for each child component of parent. Will not be altered. Can have null CC which will use a common cached one.
      callbackList - A list of callbacks or null if none. Will not be altered.

    • invalidateContainerSize

      public void invalidateContainerSize()
      If the container (parent) that this grid is laying out has changed its bounds, call this method to clear any cached values min/pref/max sizes of the components and rows/columns.

      If any component can have changed cell the grid needs to be recreated.

    • layout

      public boolean layout(int[] bounds, UnitValue alignX, UnitValue alignY, boolean debug, boolean notUsed)
      Deprecated.
      since 5.0 Last boolean is not needed and is gotten from the new ComponentWrapper.getContentBias() instead;
    • layout

      public boolean layout(int[] bounds, UnitValue alignX, UnitValue alignY, boolean debug)
      Does the actual layout. Uses many values calculated in the constructor.
      Parameters:
      bounds - The bounds to layout against. Normally that of the parent. [x, y, width, height].
      alignX - The alignment for the x-axis. Can be null.
      alignY - The alignment for the y-axis. Can be null.
      debug - If debug information should be saved in debugRects.
      Returns:
      If the layout has changed the preferred size and there is need for a new layout. This can happen if one or more components in the grid has a content bias according to ComponentWrapper.getContentBias().
      Since:
      5.0
