Get Form Name

[Henry Olive 5]

Good Day
 

I want to find out the Form Name 1 level behind of Active Form

 

In Form1 -  Form2.Show;

In Form2 -  Form3.ShowModal;

In Form3 I need the name of 1 level behind Form3, ( which is Form2 ) 

 

Thank You

There are different approaches:

• Everytime a form takes focus it inserts itself at the top of Screen.CustomForms
• ShowModal inserts the previously focused form at the top of Screen.SaveFocusedList

Thank you so much Uwe
If you have time,  could you please a little bit explain the 2 choices

and if possible could you show some code example

@Henry Olive A Delphi programmer will be able to come up with the code give the information above. There is documentation and VCL source. If you don't have a Delphi programmer on your team you have bigger problems.

Don't set Form2 and Form3 autocreated but create them yourself.

You can use the "Owner" of the forms to get the name.

 

In Form 1 you do:

uses Unit2;

procedure TForm1.BitBtn1Click(Sender: TObject);
var
  Form2: TForm2;
begin
  Form2 := TForm2.Create(Self);
  Form2.Show;
end;

In Form2 you do:

uses Unit3;

procedure TForm2.BitBtn1Click(Sender: TObject);
var
  Form3: TForm3;
begin
  Form3 := TForm3.Create(Self);
  Form3.ShowModal;
end;

In form 3 you can do: (try to find a way to do this recursively..)

procedure TForm3.BitBtn1Click(Sender: TObject);
var FormName: string;
begin
  if Assigned(Owner) and (Owner is TForm) then
  Begin
    FormName := TForm(Owner).Name;
    if Assigned(TForm(Owner).Owner) and (TForm(Owner).Owner is TForm) then
    Begin
      FormName := TForm(Owner).Owner.Name;
    End else
      FormName := 'No Owner';
  End else
    FormName := 'No Owner';

  ShowMessage('The form is: ' + FormName);
end;
