Constructor Details

Grid

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().
