## Member Function Documentation

### void QUrl::addPath ( const QString & p )

Use setPath() instead.

### bool QUrl::cdUp ()

Use resolved("..") instead.

For example, if you have code like

     QUrl url("http://example.com/Developer/");
     url.cdUp();

you can rewrite it as

     QUrl url("http://example.com/Developer/");
     url = url.resolved("..");

### void QUrl::decode ( QString & url ) `[static]`

Use fromPercentEncoding() instead.

### QString QUrl::dirPath () const

Use QFileInfo(path()).absolutePath() or QFileInfo(path()) instead.

### void QUrl::encode ( QString & url ) `[static]`

Use toPercentEncoding() instead.

### QString QUrl::fileName () const

Use QFileInfo(path()).fileName() instead.

See also setFileName().

### bool QUrl::hasHost () const

Use !host().isEmpty() instead.

### bool QUrl::hasPassword () const

### bool QUrl::hasPath () const

Use !path().isEmpty() instead.

### bool QUrl::hasPort () const

Use port() != -1 instead.

### bool QUrl::hasRef () const

Use !fragment().isEmpty() instead.

### bool QUrl::hasUser () const

Use !userName().isEmpty() instead.

### bool QUrl::isRelativeUrl ( const QString & url ) `[static]`

Use isRelative() instead.

### QString QUrl::protocol () const

Use scheme() instead.

See also setProtocol().

See also setRef().

### void QUrl::reset () `[protected]`

Use clear() instead.

### void QUrl::setFileName ( const QString & txt )

Use setPath() instead.

See also fileName().

### void QUrl::setProtocol ( const QString & s )
