boolean hoveringOnColumnResizer
```
    True if mouse is hover on a column boundary and can resize the column.
  - hasDifferingHeights
```
boolean hasDifferingHeights
```
    True if there is at least one GridItem with an individual height. This value is only set to true in GridItem#setHeight(int,boolean) and it is never reset to false.
  - topIndex
```
int topIndex
```
    Index of first visible item. The value must never be read directly. It is cached and updated when appropriate. #getTopIndex should be called for every client (even internal callers). A value of -1 indicates that the value is old and will be recomputed.
    
    See Also:
    
    bottomIndex
  - bottomIndex
```
int bottomIndex
```
    Index of last visible item. The value must never be read directly. It is cached and updated when appropriate. #getBottomIndex() should be called for every client (even internal callers). A value of -1 indicates that the value is old and will be recomputed.
    Note that the item with this index is often only partly visible; maybe only a single line of pixels is visible. In extreme cases, bottomIndex may be the same as topIndex.
    
    See Also:
