QFtp list()

[mrjj]

@magguz
for each file it will send event listInfo() signal so you need to connect to that and build a string yourself if you want
that.
void QFtp::listInfo(const QUrlInfo & i)

so you get a QUrlInfo pr file.
you can ask for string with
QString QUrlInfo::name() const

"The listInfo() signal is emitted for each directory entry found."

I have now created a second connect method and a function "addToList()" like this:

connect(m_ftp, SIGNAL(listInfo()), this, SLOT(addToList()));

and now?

[mrjj]

@magguz
HGi
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.

@mrjj said in QFtp list():

@magguz

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);

[magguz]

@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.

@mrjj

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 :)
