给你一个例子
比如窗体上有两个Listbox,下面将Listbox2中的项目拖到ListBox1中
将两个Listbox的DragMode属性设为dmAutomatic.
拖放经过事件
procedure TForm1.ListBox1DragOver(Sender, Source: TObject; X, Y: Integer;
State: TDragState; var Accept: Boolean);
begin
if TListBox(Source)=ListBox2 then
Accept:=true;
end;
//拖放落下事件
procedure TForm1.ListBox1DragDrop(Sender, Source: TObject; X, Y: Integer);
begin
ListBox1.Items.Add(Listbox2.Items[ListBox2.ItemIndex]);
end;
