Constructor Detail

Grid

public Grid(ContainerWrapper container, LC lc, AC rowConstr, AC colConstr, Map<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 alterted. callbackList A list of callbacks or null if none. Will not be alterted.

Method Detail

getHeight

public final int[] getHeight()

getWidth

public final int[] getWidth()

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.

layout

public boolean layout(int[] bounds, UnitValue alignX, UnitValue alignY, boolean debug, boolean checkPrefChange)
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. alignY The alignment for the y-axis. debug If debug information should be saved in debugRects. checkPrefChange If a check should be done to see if the setting of any new bounds changes the preferred size of a component.

Returns: If the layout has probably changed the preferred size and there is need for a new layout (normally only SWT).
