      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: @param 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: @param 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: @param 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: @param callbackList A list of callbacks or null if none. Will not be altered.

  • Method Details

    • 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

    • 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: @param 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
      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 net.miginfocom.layout.ComponentWrapper#getContentBias().
