TdxLayoutSplitterItem.OnMoved Event

Allows you to track splitter movements.

Declaration

property OnMoved: TdxLayoutSplitterItemMovedEvent read; write;

Remarks

You can handle the OnMoved event to track the splitter position and dimensions of delimited layout items within the parent group.

Event Occurrence

The OnMoved event occurs every time the splitter changes its position. The OnMoved event may occur multiple times during a splitter drag operation.

Event Parameters

Sender

Provides access to the layout splitter that raised the movement event.

AArgs

Allows you to access layout items delimited by the splitter and identify item boundaries before and after the OnMoved event.

Refer to the TdxLayoutSplitterItemMovedEvent procedural type description for detailed information on all parameters accessible within an OnMoved event handler.

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:

Delphi

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;

C++

void __fastcall TMyForm::dxLayoutSplitterItem1Moved(
  TdxLayoutSplitterItem *Sender, TdxLayoutSplitterItemMovedEventArgs *AArgs)
{
  Caption = AArgs->NearItem->Name + " Item Width: " + IntToStr(AArgs->NewNearItemBounds->Width) + " " +
    AArgs->FarItem->Name + " Item Width: " + IntToStr(AArgs->NewFarItemBounds->Width);
}
