详细描述

DelayButton is a checkable button that incorporates a delay before the button becomes checked 和 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 特性。

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