Grid
public Grid(ContainerWrapper container, LC lc, AC rowConstr, AC colConstr, java.util.Map<ComponentWrapper,CC> ccMap, java.util.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 ofparent
. Will not be altered.callbackList
- A list of callbacks ornull
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.

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 indebugRects
.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).
