Hello!

I don't know where should I have put this topic.
But maybe someone can help me, I have 2 problems:

I want to create a clock using a label!
    How can I refresh the label every second or some kind of other
interval?

I need to open a child window!
    How can I do that, didn't find any instructions, maybe wasn't
looking hard enough?


Best regards!

See Examples directory in lazarus, to get an idea on how components
and controls work!

add TTimer on the form.
set Interval to 1000.
Enabled the timer;
Create OnTimer event and change Label's caption inside the event.

add Unit2 (the unit where child form is declared) to the main form
unit's uses section.
add to your code.
  Form2.Show;

Just for future. Form2.Show worked because it's been put as autocreate
form (it's created during startup). If for some reason you don't want
to create it during startup then code looks different:
Code: [Select]var f: TForm2
begin
  f:=TForm2.Create(Self);
  f.Show;
end;But remember then to free windows as soon as you don't need it
anymore.
