C++Builder Tips: Hiding components

If you want to show or hide a group of components from time to time, put these components on a separate panel. Next, show or hide the panel as needed. You can do this in two different ways:

using the panel's methods Show and Hide:

Panel1->Show;
//... at some later time:
Panel1.Hide;

or using the panel's property Visible:

Panel1->Visible := true;
//... at some later time:
Panel1->Visible := false;

To quickly "toggle" the visibility by clicking a button, write this OnClick event handler for the button:

void __fastcall TForm1::Button1(TObject *Sender)
{
  Panel1->Visible = !(Panel1->Visible);
}
