- by neo-nant
This is the code section from inno setup.My intention is to make two Checkbox where at a time one is being selected.
But this code return error when first checkbox is clicked.
[code]
procedure CheckBoxOnClick(Sender: TObject);
var
Box2,CheckBox: TNewCheckBox;
begin
if CheckBox.Checked then ///error:"Could not call proc" [sud it be global if then how to or what to change?]
BEGIN
CheckBox.State := cbUnchecked;
Box2.State := cbChecked;
END else
BEGIN
CheckBox.State := cbChecked;
Box2.State := cbUnchecked;
END;
end;
procedure Box2OnClick(Sender: TObject);
var
Box2,CheckBox: TNewCheckBox;
begin
if Box2.Checked then ///error:same
BEGIN
CheckBox.State := cbChecked;
Box2.State := cbUnchecked;
END else
BEGIN
CheckBox.State := cbUnchecked;
Box2.State := cbChecked;
END;
end;
procedure CreateTheWizardPages;
var
Page: TWizardPage;
Box2,CheckBox: TNewCheckBox;
begin
{ TButton and others }
Page := CreateCustomPage(wpWelcome, '', '');
CheckBox := TNewCheckBox.Create(Page);
CheckBox.Top :=ScaleY(8)+ScaleX(50);
CheckBox.Width := Page.SurfaceWidth;
CheckBox.Height := ScaleY(17);
CheckBox.Caption := 'Do this';
CheckBox.Checked := True;
CheckBox.OnClick := @CheckBoxOnClick;
CheckBox.Parent := Page.Surface;
Box2 := TNewCheckBox.Create(Page);
Box2.Top :=ScaleY(8)+ScaleX(70);
Box2.Width := Page.SurfaceWidth;
Box2.Height := ScaleY(17);
Box2.Caption := 'No,Thanks.';
Box2.Checked := False;
Box2.OnClick := @Box2OnClick;
Box2.Parent := Page.Surface;
end;
procedure InitializeWizard();
//var
begin
{ Custom wizard pages }
CreateTheWizardPages;
end;
