Hide Widget after 3 seconds with QTimer problem

[roosaw]

Hi I wanna hide the widget after 3 seconds (3000 miliseconds). I done something like that:
I used variable
@QTimer timer;@
in class Class.
and
where I call function I'm doing:
@timer.start(3000);
button->show();
@
In constructor there is something like:
@connect(timer, SIGNAL(timeout()), button, SLOT(hide()));@
When I'm compiling it throws me an error:
@file.cpp:34: error: no matching function for call to ‘Class::connect(QTimer&, const char [11],
QPushButton*&, const char [8])’@
What is all about? how to fix it? button is a pointer, timer is a variable

Try this
@connect(&timer, SIGNAL(timeout()), button, SLOT(hide())); @
