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 of parent
. Will not be alterted.callbackList
- A list of callbacks or null
if none. Will not be alterted.
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).
