Description

Methods

	`procedure DoTimer; virtual;`

	`procedure Update(const SecondsPassed: Single; var HandleInput: boolean); override;`

	`function PropertySections(const PropertyName: String): TPropertySections; override;`

Properties

	`property IntervalSeconds: TFloatTime read FIntervalSeconds write SetIntervalSeconds;`
How often should we call OnTimer. Value of 0 means to call OnTimer in every Update event.

	`property OnTimer: TNotifyEvent read FOnTimer write FOnTimer;`
The event called periodically.

	`property CounteractDelays: boolean read FCounteractDelays write FCounteractDelays default false;`
Should we counteract the delays in timer by firing next event sooner. This helps to keep a constant frequency of timer events over a long time, and to keep multiple things (like multiple timer instances) perfectly synchronized with each other. But it may cause to execute a lot of timer events at once, in case the application hung for some time.
