## Detailed Description

DelayButton is a checkable button that incorporates a delay before the button becomes checked and the activated() signal is emitted. This delay prevents accidental presses.

The current progress is expressed as a decimal value between `0.0` and `1.0`. The time it takes for activated() to be emitted is measured in milliseconds, and can be set with the delay property.

The progress is indicated by a progress indicator on the button.

See also Customizing DelayButton and Button Controls.

## Property Documentation

delay : int

This property holds the time it takes (in milliseconds) for progress to reach `1.0` and emit activated().

The default value is `3000` ms.

[read-only] progress : real

This property holds the current progress as displayed by the progress indicator, in the range `0.0` - `1.0`.

transition : Transition

This property holds the transition that is applied on the progress property when the button is pressed or released.

## Signal Documentation

activated()

This signal is emitted when progress reaches `1.0`.

Note: The corresponding handler is `onActivated`.
