Declaration

type TCEFSentinel = class(TComponent)

Description

TCEFSentinel is used as a timer that checks the number of running CEF processes when you close all browsers before shutdown. This component is only used as a last resort when there's an unresolved shutdown issue in CEF or CEF4Delphi that generates exceptions when the application is closed.

	`procedure Start; virtual;`
Start checking all the CEF subprocesses.

Properties

	`property Status : TSentinelStatus read GetStatus;`
Status of this component.

	`property ChildProcCount : integer read GetChildProcCount;`
Number of CEF subprocesses.

	`property DelayPerProcMs : cardinal read FDelayPerProcMs write FDelayPerProcMs default CEFSENTINEL_DEFAULT_DELAYPERPROCMS;`
Delay per subprocess in milliseconds. This delay is used to calculate how much time to wait until this component checks the CEF subprocesses again.

	`property MinInitDelayMs : cardinal read FMinInitDelayMs write FMinInitDelayMs default CEFSENTINEL_DEFAULT_MININITDELAYMS;`
Minimum initial delay in milliseconds. This is the minimum time to wait until this component checks the CEF subprocesses again.

	`property FinalDelayMs : cardinal read FFinalDelayMs write FFinalDelayMs default CEFSENTINEL_DEFAULT_FINALDELAYMS;`
Final delay in milliseconds. This is an extra delay to wait after enough CEF subprocesses are closed.

	`property MinChildProcs : integer read FMinChildProcs write FMinChildProcs default CEFSENTINEL_DEFAULT_MINCHILDPROCS;`
Minimum number of CEF subprocesses. When ChildProcCount reaches this value it's considered safe to trigger OnClose.

	`property MaxCheckCount : integer read FMaxCheckCount write FMaxCheckCount default CEFSENTINEL_DEFAULT_MAXCHECKCOUNTS;`
Maximum number of times this component will check the CEF subprocesses.

	`property OnClose : TNotifyEvent read FOnClose write FOnClose;`
Event triggered when enought CEF subprocesses are closed.
