TdxGanttControlTaskEndLinkEvent Type

Performs a set of actions after tasks were linked with a dependency created by a mouse drag-and-drop operation.

Declaration

TdxGanttControlTaskEndLinkEvent = procedure(Sender: TObject; APredecessorLink: TdxGanttControlTaskPredecessorLink) of object;

Parameters

Name	Type	Description
Sender	TObject	The Chart View that raised the event.
APredecessorLink	TdxGanttControlTaskPredecessorLink	The newly created dependency.

Remarks

You can open the Features Demo and modify its code. Handle the OnTaskEndLink event and use the following code snippet to display the message that one task is the predecessor for another task:

Delphi

procedure TFeaturesDemoMainForm.GanttControlViewChartTaskEndLink(Sender: TObject;
  APredecessorLink: TdxGanttControlTaskPredecessorLink);
begin
    ShowMessage('The ''' + GanttControl.DataModel.Tasks.GetItemByUID(APredecessorLink.PredecessorUID).Name + ''' task is now the predecessor of the ''' + APredecessorLink.Task.Name + ''' task');
end;

C++

void __fastcall TFeaturesDemoMainForm::GanttControlViewChartTaskEndLink(TObject *Sender,
          TdxGanttControlTaskPredecessorLink *APredecessorLink)
{
    ShowMessage("The '" + GanttControl->DataModel->Tasks->GetItemByUID(APredecessorLink->PredecessorUID)->Name + "' task is now the predecessor of the '" + APredecessorLink->Task->Name + "' task");
}
