Title: Disable an event handler
Question: Sometimes you want to disable an event handler after the FIRST time. E.g., you want to disable all clicks on a component AFTER THE FIRST CLICK, this is how you do it.
Answer:
Sometimes you want to disable an event handler after the FIRST time. E.g., you want to disable all clicks on a component AFTER THE FIRST CLICK:
procedure ComponentOnClick;
begin
Button1.OnClick := nil;
end;
In the case of a button Onclick you obtain the same effect by disabling the button itself, and at the same time you give a visual feedback. So this trick only makes sense for other events and components.
