Declaration
property FarItem: TdxCustomLayoutItem read; write;
Property Value
Type | Description |
---|---|
TdxCustomLayoutItem | The far layout item associated with the splitter that raised the OnClosed, OnMoved, or OnOpened event. You can use OldFarItemBounds and NewFarItemBounds properties to identify far item dimensions after a splitter resize, expand, or collapse operation. |
Remarks
Use FarItem
and NearItem properties to identify and access layout items delimited by the splitter that raised the OnClosed, OnMoved, or OnOpened event.
Near, Far, and Target Layout Items
Near and far item positions depend on the parent layout group‘s LayoutDirection property value:
- ldVertical
- Default. The group arranges items from top to bottom. The near item is above the splitter, and the far item is below it.
- ldHorizontal
- The group arranges items from left to right. Near and far items are to the left and right of a splitter, respectively.
The target item is the near or far layout item associated with the splitter, depending on AlignVert and AlignHorz property values as well as the parent group direction.
For example, the near item is the splitter target if the parent group is horizontally arranged, and the AlignHorz property is set to ahLeft:
Code Example: Track Splitter Movement
The following code example demonstrates an OnMoved event handler that displays names and sizes of layout items delimited by the currently dragged splitter in a horizontally arranged layout group:
procedure TMyForm.dxLayoutSplitterItem1Moved(
Sender: TdxLayoutSplitterItem; AArgs: TdxLayoutSplitterItemMovedEventArgs);
begin
Caption := AArgs.NearItem.Name + ' Item Width: ' + IntToStr(AArgs.NewNearItemBounds.Width) + ' ' +
AArgs.FarItem.Name + ' Item Width: ' + IntToStr(AArgs.NewFarItemBounds.Width);
end;
