Method Detail

addOrMoveSlot

@Deprecated
public void addOrMoveSlot(Slot slot,
                                      int index)

Deprecated. since 7.1.4, use addOrMoveSlot(Slot, int, boolean)

See the method addOrMoveSlot(Slot, int, boolean).

This method always adjusts spacings for the whole layout.

Parameters:

slot - The slot to move or add

index - The index where the slot should be placed.

addOrMoveSlot

public void addOrMoveSlot(Slot slot,
                          int index,
                          boolean adjustSpacing)

Add or move a slot to another index.

For internal use only. May be removed or replaced in the future.

You should note that the index does not refer to the DOM index if spacings are used. If spacings are used then the index will be adjusted to include the spacings when inserted.

For instance when using spacing the index converts to DOM index in the following way:

 index : 0 -> DOM index: 0
 index : 1 -> DOM index: 1
 index : 2 -> DOM index: 3
 index : 3 -> DOM index: 5
 index : 4 -> DOM index: 7
 

When using this method never account for spacings.

The caller should remove all spacings before calling this method and re-add them (if necessary) after this method. This can be done before and after all slots have been added/moved.

Parameters:

slot - The slot to move or add

index - The index where the slot should be placed.

adjustSpacing - true to recalculate spacings for the whole layout after the operation

Since:

7.1.4
