qt按钮发出多个信号 [英] qt button to emit multiple signals

问题描述

是否有一个Qt(我使用Qt 4.7.1)小部件会在按下时发出信号(第一次时不仅发出信号)，并在用户释放鼠标时停止发出信号?像是标准间隔内的mousedown事件? 还是我必须用qtimer来实现呢? 谢谢

is there a Qt (I use Qt 4.7.1) widget that emit signals (not just one at the first time) while it is pressed and stops when the user releases the mouse? something like mousedown events in standard intervals? or do I have to implement this with a qtimer? thanks

Check out QAbstractButton::autoRepeat and autoRepeatInterval. It should be exactly what you need and is available for all buttons.
