You did it wrong.
This is how you should use TSelectDirectoryDialog:
Code: Pascal
[Select]
[+]
[-]
unit
Unit1
;
{$mode objfpc}{$H+}
interface
uses
Classes
,
Forms
,
Controls
,
Dialogs
,
StdCtrls
;
type
{ TForm1 }
TForm1
=
class
(
TForm
)
Button1
:
TButton
;
SelectDirectoryDialog1
:
TSelectDirectoryDialog
;
procedure
Button1Click
(
Sender
:
TObject
)
;
end
;
var
Form1
:
TForm1
;
implementation
{$R *.lfm}
{ TForm1 }
procedure
TForm1
.
Button1Click
(
Sender
:
TObject
)
;
begin
if
not
(
SelectDirectoryDialog1
.
Execute
)
then
Exit
;
ShowMessage
(
SelectDirectoryDialog1
.
FileName
)
;
end
;
end
.

I don't understand. In my example the TSelectDirectoryDialog control is on form2 in my example and when I run the program the control doesn't show.
