[Solved] Connecting a QPushButton and a function
-
I'm creating a QPushButton, putting it on the form and then connecting it so that when it gets clicked, a function is called. This is what I have in the .h file:
@
private:
QPushButton *manAutoButton;private slots:
void on_manAutoButton_clicked();
@
And this is what's in the .cpp file:
@
manAutoButton = new QPushButton(this);
manAutoButton->resize(84, 84);
manAutoButton->move(629, 270);
connect(manAutoButton, SIGNAL(clicked()), this, SLOT(on_manAutoButton_clicked()));
@
When the app runs, everything is fine. The function gets called whenever I click the manAutoButton. The only thing is that I get the following message in the run window: "QMetaObject::connectSlotsByName: No matching signal for on_manAutoButton_clicked()". What am I doing wrong?EDIT: moved to General, peppe

You have to create the on_manAutoButton_clicked() function in your .cpp file.

Yes, it was already in there. For completeness, this is it:
@
void MonitorWindow::on_manAutoButton_clicked()
{
if(mode == Auto)
{
mode = Manual;
ui->label_28->setText("MAN");
manAutoButton->setIcon(QIcon(QPixmap(":/MonitorWindowPix/Automatic1.png")));
}
}

Try to remove on_ from slot name.
@private slots:
void manAutoButton_clicked();...
connect(manAutoButton, SIGNAL(clicked()), this, SLOT(manAutoButton_clicked()));
...
void MonitorWindow::manAutoButton_clicked()

Thanks - that did it. I guess the buttons that are placed on Designer UI forms are automatically connected to the on_buttonname_clicked functions, but creating your own functions in that format creates some confusion.
