QFtp list()

its :listInfo(const QUrlInfo & i)
so syntax is not correct

connect(m_ftp, SIGNAL(listInfo(const QUrlInfo &), this, SLOT(addToList(const QUrlInfo &));
and change addToList so it takes that parameter.
For each file it calls it
and you can build your list or what you need.

and change addToList so it takes that parameter.

how I can take the parameter into the addToList function?

[mrjj]

@magguz
just change the addToList so it the real slot have a variable name.
(not in the connect. they are always without names)

void addToList(const QUrlInfo & file);

@mrjj

I changed the addToList() to addToList(const QUrlInfo & file)
Now I get an object named "file" for every directory entry, right?

[mrjj]

@magguz
yes you get an URL object for each file
and the (QUrlInfo) file has a function called
name() that returns a QString.

now I want to append the strings to a textEdit like this:

ui->textEdit->append(file.name());

but it doesn't work

[mrjj]

@magguz
in what way "doesn't work" ?
What does it append?
is the addToList called ?

no it seems that addToList is not called. It appends nothing.

@magguz
well check all your connects like
qDebug() << "status:" << connect(xxxx); // xxxx being what u have
and see they return true.
also test that it does connect to the server. check errors and such.

@mrjj

I found what was wrong. I changed

ftp->login("","");

in

ftp->login();

and it works. Thanks for your help!

[magguz]

There is still one thing: In the TextEdit he lists all entries sixteen times

[mrjj]

@magguz
Hi
well
what does file.name() contains ?
in
ui->textEdit->append(file.name());

I cant guess , please debug it using the debugger so you can see what happens.

@mrjj

I changed the connect statements like this:

connect(ftp, SIGNAL(listInfo(const QUrlInfo &)), this, SLOT(addToList(const QUrlInfo &)), Qt::UniqueConnection);

I added only Qt::UniqueConnection as parameter. Now everything is fine :-)

[mrjj]

@magguz
Ahh, you might have added the connect many times :)
well UniqueConnection solves also :)
