KURLDrag Class Reference

#include <kurldrag.h>

Inheritance diagram for KURLDrag:

QUriDrag List of all members.

Detailed Description

This class is to be used instead of QUriDrag when using KURL.

The reason is: QUriDrag (and the XDND/W3C standards) expect URLs to be encoded in UTF-8 (unicode), but KURL uses the current locale by default. The other reasons for using this class are:

  • it exports text/plain (for dropping/pasting into lineedits, mails etc.)
  • it has support for metadata, shipped as part of the dragobject This is important, for instance to set a correct HTTP referrer (some websites require it for downloading e.g. an image).
To create a drag object, use the KURLDrag constructor. To handle drops, use QUriDrag::canDecode() and KURLDrag::decode()

Constructor & Destructor Documentation

KURLDrag::KURLDrag ( const KURL::List urls,
QWidget dragSource = 0,
const char *  name = 0 
)

Constructs an object to drag the list of URLs in urls.

The dragSource and name arguments are passed on to QUriDrag, and the list of urls is converted to UTF-8 before being passed to QUriDrag.

Parameters:
urls the list of URLs
dragSource the parent of the QObject. Should be set when doing drag-n-drop, but should be 0 when copying to the clipboard
name the name of the QObject

KURLDrag::KURLDrag ( const KURL::List urls,
const QMap< QString, QString > &  metaData,
QWidget dragSource = 0,
const char *  name = 0 
)

Constructs an object to drag the list of URLs in urls.

This version also includes metadata.

Parameters:
urls the list of URLs
metaData a map containing meta data
dragSource the parent of the QObject. Should be set when doing drag-n-drop, but should be 0 when copying to the clipboard
name the name of the QObject

KURLDrag::KURLDrag ( const QStrList urls,
const QMap< QString, QString > &  metaData,
QWidget dragSource,
const char *  name 
) [protected]

Deprecated:
Use a KURLDrag constructor with a KURL::List

Member Function Documentation

void KURLDrag::setExportAsText ( bool  exp  ) 

By default, KURLDrag also exports the URLs as plain text, for e.g.

dropping onto a text editor. But in some cases this might not be wanted, e.g. if using the KURLDrag in a KMultipleDrag and another component of the multiple-drag provides better plain text data. In such a case, setExportAsText( false ) should be called.

QMap<QString, QString>& KURLDrag::metaData (  )  [inline]

Meta-data to associate with those URLs.

This is an alternative way of setting the metadata: either use the constructor to pass it all at once, or use drag->metaData()["key"] = data;

bool KURLDrag::decode ( const QMimeSource e,
KURL::List urls 
) [static]

Convenience method that decodes the contents of e into a list of KURLs.

Decoding will fail if at least one decoded value is not a valid KURL.

Parameters:
e the mime source
urls the list of urls will be written here
Returns:
true if successful, false otherwise

bool KURLDrag::decode ( const QMimeSource e,
KURL::List urls,
QMap< QString, QString > &  metaData 
) [static]

Convenience method that decodes the contents of e into a list of KURLs and a set of metadata.

Decoding will fail if at least one decoded value is not a valid KURL. You should be using this one, if possible.

Parameters:
e the mime source
urls the list of urls will be written here
metaData the metadata map will be written here
Returns:
true if successful, false otherwise
