- Qt 5 continues to support the old string-based syntax for connecting signals and slots defined in a QObject or any class that inherits from QObject (including QWidget) connect (sender, SIGNAL (valueChanged (QString, QString)), receiver, SLOT (updateValue (QString))); New: connecting to.
- How Qt Signals and Slots Work - Part 3 - Queued and Inter Thread Connections. Since the thread is blocked, the event will never be processed and the thread will be blocked forever. Qt detects this at run time and prints a warning, but does not attempt to fix the problem for you.
Qt Thread Slot Signal Analyzer
I have a Qt 'signal-slot connection'.
I want to test the class with the signal
The class with the slot is mocked/stubbed.
Now I would like to verify that when I emit signal, the slot is
called.
I wonder if it is possible to use gmock to verify this.
// class Tx contains the signal, which is protected so I inherit
// to get access to it
class Test : public ::testing::Test, public Tx
{ public:
MockRx *rx;
void SetUp()
{ rx = new MockRx;
rx->rxsignal(); // Just to see it compiles
rx->gmock_rxsignal(); // Compiles, gmock generated function
QObject::connect(this, SIGNAL(txsignal(), rx, SLOT(rxsignal()));
}
void TearDown() { delete rx; }
};
TEST_F(Test, Signal)
{
EXPECT_CALL(*rx, rxsignal()).Times(1).WillOnce(Return());
this->txsignal();
}
class MockRx : public QWidget
{ Q_OBJECT
public:
MOCK_METHOD0(rxsignal, void());
};
When running, I get the error:
QObject::connect: No such slot as RxMock::rxsignal()
If I remove Q_OBJECT in class MockRx, I get: No such slot as
QWidget::rxsignal()
I also tried to QObject::conntect(.. SLOT(gmock_rxsignal()));
which gives No such slot as RxMock::rxsignal()
If I replace the MockRx class with a class Rx with rxsignal()
everything works.
I wonder why QObject::connect cannot find RxText::rxsignal() when
- it works if I replace with a regular class Rx instead of class
MockRx
- rx->rxsignal() can be called
Is gmock doing something under the hood that prevents this?
Hope someone can help, thanks a lot
