Qtest does not emit signal

[NIK-VAJ]

I want to simulate mouse click in a application. I use QT::mouseclick and QT::mousemove to click in different positions. when I run code, position of my pushbutton was clicked but the related SLOT doesn't run. Doesn't QTest emit signal? How do I simulate mouse click with signal?

QTest is a namespace and doesn't have any signals.

If a widget has a signal and you provide the input it needs to emit it, then it will do so. It doesn't know whether it is in an application or running in a test.

So if you don't get a slot called, then there is either a problem with the signal/slot connection, in which case you can try QSignalSpy to verify this, or the widget has not received the events that it needs to trigger the emit, in which case you either have to debug how the correct event sequence is or find another way to trigger, e.g. in case of a button QAbstractButton::click().

thanks. I try click() and it was OK but could I find a way that doesn't need the name of pushbuttons or other elements? I want to use only x and y position to simulate fake click and get signal of events.

When you used the QTest::mouseClick() method, did you use the one taking a QWidget or the one taking a QWindow?

I use this code:

QTest::mouseMove(this,mapToGlobal(QPoint(x,y)));
QTest::mouseClick(this, Qt::LeftButton,0, mapToGlobal(QPoint(x,y)),-1);

"this" is mainwindow. my code shoud be independent of name of widgets like pushbutton.

[anda_skoa]

mapToGlobal doesn't make much sense unless you have ensured that the windows is positioned at 0,0 and thus global/local coordinates being the same.

In either case, you likely need the overload that takes a QWindow, the one that takes a QWidget delivers mouse event to that specific widget.

thanks for your quick replies
even when I use qwidget in mousclick function, it doesn't emit a signal!

So you changed the code to send the clicks to the button and it does not emit the signal?
Can you show the code you have now?

if (event->button()==Qt::RightButton){
qDebug() << Qt::RightButton << pos();
QPoint Mpush = pos();
QTest::mouseMove(this->m_button,Mpush);
QTest::mouseClick(this->m_button, Qt::LeftButton,0,Mpush,-1);}
in this code, when I Rightclicked on button, the position of cursor places in Mpush and then lift click is simulated. it doesn't emit pushbutton(m_button) signal.

[anda_skoa]

So you are trying to simulate a mouse click on "m_button", at x=751, y=327 in "m_button".

Are you certain that the button is really that large?

Is it important for your button where it is clicked?
If not you could just omit the position and it gets clicked in its center.

pos() is not position of cursor in the screen?
and how can I find center of poshbutton?
