Enum Constant Detail

BETWEEN

public static final DropMode BETWEEN

The drop event can happen between Grid rows. The drop is above a row when the cursor is over the top 50% of a row, otherwise below the row.

ON_TOP

public static final DropMode ON_TOP

The drop event can happen on top of Grid rows. The target of the drop is the row under the cursor at the time of the drop event.

ON_TOP_OR_BETWEEN

public static final DropMode ON_TOP_OR_BETWEEN

The drop event can happen either on top of or between Grid rows. The drop is either

• above a row when the cursor is over a specified portion of the top part of the row,
• below when the cursor is over a specified portion of the bottom part of the row, or
• on top when the cursor is over the row but doesn't match the above conditions.

ON_GRID

public static final DropMode ON_GRID

The drop event will not happen on any specific row, it will show the drop target outline around the whole grid. For this drop target, the drop event will not contain any target row information. This is the drop target used when the grid is completely empty. It can also be configured to be used automatically when the user has sorted the grid.

When this mode is used, it also recommended to automatically scroll the dropped data (new rows) to be visible for the user.
