You can create (or maybe display) a "box" (in this example a TRichEdit
control)
when the mouse goes down on your panel, and destroy (or maybe hide) the
"box"
when the mouse goes up on your panel (or held down and moved away from the
panel
and then released) by using the  event handlers corresponding to the
OnMouseDown and OnMouseUp events:

TRichEdit* p1;

void __fastcall TForm1::Panel1MouseDown(TObject *Sender,
      TMouseButton Button, TShiftState Shift, int X, int Y)
{
  if (Button == mbLeft)
  {
      // Create your component here
      p1 = new TRichEdit(this);
      p1->Parent = this;
      //...
  }
}


void __fastcall TForm1::Panel1MouseUp(TObject *Sender, TMouseButton Button,
      TShiftState Shift, int X, int Y)
{
  if (Button == mbLeft)
      delete p1;         // Destroy your component here

}
