The Qt documentation in C++ of this class can be read here: http://doc.trolltech.com/4.3/qobject.html
Please read the control class overview Control as well.
A form control may use as many timer controls as you desire. Be aware that the form control comes with a built-in timer. See TimerInterval for more details.
To make your application perform idle processing (i.e. executing a special function whenever there are no pending events), use a Timer with an Interval set to -1.
Function IsRunning() As Boolean
Property Interval As Integer (ReadWrite)
A timer with a interval of 0 will time out as soon as all the events in the window system's event queue have been processed.
ReadWrite Enabled As Boolean
If you it is set True, the timer event will start automatically after opening the form. Do not forget to set Interval of the timer.
ReadOnly EventOnOpen As Boolean
If you it is set True, the timer event will start automatically after opening the form, but not waiting for the interval to raise the first OnEvent. It is done after OnOpen. Do not forget to set Interval of the timer.
This event is raised, whenever the timer interval is reached.
