Qtimer::singleshot slot completed

Qt Enthusiast

Hi All
Is there any way I can find out that slot
QTimer::singleShot(1500, this, std::bind(&MyClass::crossCapture, this, getMousePointerX(), getMousePointerY()));

has been completed

VRonin

put qDebug("Completed"); as the first line of MyClass::crossCapture

Qt Enthusiast

I am passing a reference variable as bool in slot of Qtimer::singleShot and then accesing this variable in called and putting a while loop on the same to check of the slot is completed any other way to do that

VRonin

Are you using multiple threads? if not what you are doing is totally useless. No instruction can be performed while another is in the same thread

Hi All

Is there any way I can find out that slot updateGui is completed .

QTimer::singleShot(0, this, updateinMaingui());

VRonin

Then the only solution is have a signal in the main thread that fires when that method completed

Qt Enthusiast

if you can help me with the sample code

VRonin

class MyClass : public QObject{
Q_OBJECT

// other stuff

public:
Q_SIGNAL void crossCaptureFinished();
void crossCapture(int x, int y){

//other stuff

emit crossCaptureFinished();
}
};

[edit: added missing emit keyword SGaist]

@Qt-Enthusiast could you please described in words what's your requirement or what you're trying to do overall? You've already have asked about QTimer::singleShot, and now this loop inside it, it sounds that you might be over complicating things...
