Field Details
- hoveringOnColumnResizer
  
  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:
  
  topIndex
- startColumnIndex
  
  int startColumnIndex
  
  Index of the first visible column. A value of -1 indicates that the value is old and will be recomputed.
- endColumnIndex
  
  int endColumnIndex
  
  Index of the the last visible column. A value of -1 indicates that the value is old and will be recomputed.
