Setting TRadioButton to checked causes OnClick event

Question

mybox.Checked := true;

Setting TRadioButton to checked (by code) causes OnClick event handler to be called.

How can I recognize if user is

Answer 1

TRadioButton (like TCheckBox) provides a protected property ClicksDisabled that can help you.

I use class helpers to add the needed functionality:

RadioButton1.SetCheckedWithoutClick(False);

with the following class helper for a VCL TRadioButton:

TRadioButtonHelper = class helper for TRadioButton
    procedure SetCheckedWithoutClick(AChecked: Boolean);
end;

procedure TRadioButtonHelper.SetCheckedWithoutClick(AChecked: Boolean);
begin
    ClicksDisabled := True;
    try
        Checked := AChecked;
    finally
        ClicksDisabled := False;
    end;
end;
