What Does The OnIdle Event In DelphiVCL.Application Do?

DelphiVCLApplicationObservers blog banner

During Windows development, the OnIdle or DelphiVCL.Application.OnIdle occurs when an application becomes idle.

Write an OnIdle event handler to perform special processing when an application is idle. An application is idle when it is not processing code. For example, an application is idle when it is waiting for input from the user.

OnIdle is called only once, as the application transitions into an idle state. It is not called continuously unless the Done parameter is set to false. Applications that set Done to false consume an inordinate amount of CPU time, which affects overall system performance.
