Detailed Description

A DelayButton

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.
