Object::connect: No such slot MainWindowImpl::rowClicked(QModelindex)

[JeanC]

New to qt, using qdevelop.

For a few days now I'm trying get an event working when a row is clicked in a tableview.
I think I have all the syntax right but the event is still not firing and I'm getting out of options.

In Mainwindow.ui, a signal / slot pair exists that connects the table pressed(QModelIndex) to the MainWindow.

<sender>table</sender>
<signal>pressed(QModelIndex)</signal>
<receiver>MainWindow</receiver>
<slot></slot>


Then I have this code, in mainwindowimpl.h

private slots:
void rowClicked(const QModelIndex &);

and in mainwindowimp.cpp:
in constructor:

connect(table, SIGNAL(pressed(const QModelIndex &)), this, SLOT(rowClicked(const QModelindex &)));

member function:

void MainWindowImpl::rowClicked(const QModelIndex &index)
{
int row = index.row();
QString name = model->record(row).value("name").toString();
setWindowTitle(name);
}

That event does not get called, why not? Voodoo?
Help is appreciated.

Have you tried using the signal clicked(const QModelIndex&)? I'm not sure it'll change your results, but it couldn't hurt [ pressed() is for a mouse press, clicked() for a mouse click... ymmv]

rowClicked(QModelindex)

and

rowClicked(const QModelIndex &)

are not the same.

Thanks folks.

@vycke
Yes i tried that, same result, nothing.

@high_flyer
I have nowhere 'rowClicked(QModelindex)' in my code, I use the designer and there it's called like that. If you open the ui file in kate yes, but that's done by the designer, isn't it.

So I'm not clear what you mean.

[high_flyer]

why are you defining slots with designer if you don't use them?
Is the warning that you posted in the subject is the only one you get?

to make sure that the slot really is not being called, add a debug message, and see if it comes out in the console.
It could be that the slot is called and for some other reason you don't see the effect you expect.

Well I was told this in another thread:

---
void QAbstractItemView:ressed( const & index ) [signal]
as you can see signal argument type is const QModelIndex & not QModelIndex
---

I tried to drop the const and the & everywhere but no succes.
I tried qDebug() << "in callback"; but did not show up.

Thanks.

First prize goes to the person who solves this riddle.

[high_flyer]

don't define the slot as private, since other objects cant call it.
make it public.

[JeanC]

Done, no change.

These I get:
Object::connect: Parentheses expected, slot MainWindowImpl::
Object::connect: (sender name: 'actionExit')
Object::connect: (receiver name: 'MainWindow')
Object::connect: Parentheses expected, slot MainWindowImpl::
Object::connect: (sender name: 'table')
Object::connect: (receiver name: 'MainWindow')
Object::connect: No such slot MainWindowImpl::rowClicked(QModelindex)
Object::connect: (sender name: 'table')
Object::connect: (receiver name: 'MainWindow')

From this:
setupUi(this);
connect(actionExit, SIGNAL(triggered()), this, SLOT(exitClicked()));
connect(table, SIGNAL(clicked(const QModelIndex &)), this, SLOT(rowClicked(const QModelindex&)));

That other event, actionExit, is working though.

[JeanC]

From that error you would expect something's wrong with that syntax in the connect() calls.
removing the const and & still displays Parenthesis expected.

[high_flyer]

it should be QModelIndex not QModelindex.

Where is actionExit defined?

[JeanC]

Good spot!
It works.!!!

pfff, thanks a bunch.
