How to use a checkbox in Delphi?

Right now, I have the code:

begin
If odd(GetAsyncKeyState(VK_snapshot)) then
If CheckBox1.Checked then
begin

And then it continues on with the rest of the code. Is that the correct way of doing that, or am I doing it wrong?

Solution

  • What you suggest is a perfectly legal way to determine if a checkbox is checked. The code doing so might look like

    if checkBox.Checked then begin
    //do whatever needed for checked checkbox
end

    or like this

    if checkBox.Checked then begin
    //do whatever needed for checked checkbox
end else begin
    //do whatever needed for unchecked checkbox
end

    Just remember that the value you obtained from Checked property corresponds to the checkbox's state at the moment when you obtained the value.
