c++ - Qt handling QPushButton Autorepeat() behavior with isAutoRepeat() -

i'm new qt , making widget interfaces pre-existing gui. i'd have widget continuously output 1 signal while user has pushbutton pressed , continuously output when released.

by enabling autorepeat can have widget output signal while user pressing pushbutton, however, output signal switches between pressed() , released(). e.g.

<> outputs: * pressed signal * released signal * pressed signal * released signal

i've seen question been asked keypressevents i'm not sure how access isautorepeat() pushbuttons. can give me advice on this?

one way can use timer object achieve this. below example, run 2 slot's when button pressed , released. code comment explain in detail. when button pressed & released text box show continuous time in milli-seconds. timer object emit timeout() signal in given interval. need stop , start alternate timers in button pressed / released signal. application created using qt creator "qt widgets application" wizard. hope help.
