I have a form which is being dynamically created within a class. I guess, for a component there should be no difference...
Here is the stripped sample:
TISFields = class(TObject)
private
SortForm: TForm;
XMargin, YMargin: Integer;
procedure ButtonOkClick(Sender: TObject);
public
constructor Create;
destructor Destroy; override;
function SortDialog: Boolean;
end;
constructor TISFields.Create;
begin
XMargin := 10;
YMargin := 10;
end;
destructor TISFields.Destroy;
begin
inherited Destroy;
end;
function TISFields.SortDialog: Boolean;
var
aButton: TButton;
begin
SortForm := TForm.Create(Application);
with SortForm do
begin
Name := 'formISSort';
Position := poScreenCenter;
Caption := 'Select Fields for Sorting';
BorderStyle := bsDialog;
BorderIcons := [];
ClientHeight := 200; // Set it to what it should be in your case
ClientWidth := 300; //
end;
// Do whatever you need to do and populate window with controls
// similar to how Ok and Cancel buttons are created below
aButton := TButton.Create(SortForm);
with aButton do
begin
Parent := SortForm;
Name := 'formISSortOKButton';
Caption := '&OK';
Default := True;
Height := 21;
Left := SortForm.ClientWidth - Width - XMargin;
Top := SortForm.ClientHeight - Height - YMargin;
ModalResult := mrOk;
OnClick := ButtonOkClick;
end;
aButton := TButton.Create(SortForm);
with aButton do
begin
Parent := SortForm;
Name := 'formISSortCancelButton';
Caption := '&Cancel';
Cancel := True;
Height := 21;
Left := SortForm.ClientWidth - (Width + XMargin) * 2;
Top := SortForm.ClientHeight - Height - YMargin;
ModalResult := mrCancel;
end;
if SortForm.ShowModal = mrOk then
Result := True
else
Result := False;
// Clean up
SortForm.Release;
end;
procedure TISFields.ButtonOkClick(Sender: TObject);
begin
// Do whatever you have to do
end;
Hope I didn't miss anything... If you need any more details, please let me know.
