Type TELEvExceptionNotifyMeth

Code (Delphi)

TELEvExceptionNotifyMeth = procedure(

AExceptionInfo: TEurekaExceptionInfo;

var AHandle: Boolean;

var ACallNextHandler: Boolean

) of object;

Tip

Set ACallNextToHandler to False, if you set AHandle to False.

Note

If "Catch handled exception" option is enabled - this event will also fire for any handled exception.

You can determinate the kind of exception (handled or unhandled) by analyzing properties of AExceptionInfo argument (see Handled property).

Tip

You can also use exception filters instead of this event.

Caution!

Any event is called from the context of exception thread, which may be not the main thread of application. Thus, it's highly recommended to avoid using any global-like data and to avoid access VCL objects. If you still need to do any of that - please use proper thread synchronization for globals and Synchronize method for VCL access.

Warning

Event handlers registered via TEurekaLogEvents component will be active only when corresponding form is live (created). Such handlers will not be called before form is created or after it was destroyed. For this reason you may want to register your event handlers via code. For example, it would be a bad idea to use TEurekaLogEvents component for implementing your error dialog, because your dialog will not be displayed for exceptions outside form (e.g. initialization/finalization exceptions, as well as exceptions in form's constructor).

Code (Delphi)

try

raise Exception.Create('Error'); // - OnRaise event

finally

 ...

end;

// - OnExceptionNotify will be called

Code (Delphi)

try

raise Exception.Create('Error'); // - OnRaise event

except

 ...

end;

// - OnExceptionNotify will not be called, since exception was handled by the code

Code (Delphi)

procedure MyExceptionNotify(const ACustom: Pointer; AExceptionInfo: TEurekaExceptionInfo; var AHandle: Boolean; var ACallNextHandler: Boolean);

begin

 // Disable exception processing by EurekaLog

 Handle := False;

 ACallNextHandler := False;

end;
