## Detailed Description

The 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 around the button. When the indicator reaches completion, it flashes.
