- \class TQClipboard tqclipboard.h - \brief The TQClipboard class provides access to the window system clipboard. - - \ingroup io - \ingroup environment - \mainclass - - The clipboard offers a simple mechanism to copy and paste data - between applications. - - TQClipboard supports the same data types that TQDragObject does, and - uses similar mechanisms. For advanced clipboard usage - read \link dnd.html the drag-and-drop documentation\endlink. - - There is a single TQClipboard object in an application, and you can - access it using TQApplication::clipboard(). - - Example: - \code - TQClipboard *cb = TQApplication::clipboard(); - - // Copy text from the clipboard (paste) - TQString text = cb->text(TQClipboard::Clipboard); - if ( !text.isNull() ) - qDebug( "The clipboard contains: " + text ); - - // Copy text into the clipboard - cb->setText( "This text can be pasted by other programs", - TQClipboard::Clipboard ); - \endcode - - TQClipboard features some convenience functions to access common data - types: setText() allows the exchange of Unicode text and - setPixmap() and setImage() allows the exchange of TQPixmaps - and TQImages between applications. The setData() function is the - ultimate in flexibility: it allows you to add any TQMimeSource into the - clipboard. There are corresponding getters for each of these, e.g. - text(), image() and pixmap(). - - You can clear the clipboard by calling clear(). - - - \section1 Platform Specific Information - - \section2 X11 - - \list - - \i The X11 Window System has the concept of a separate selection - and clipboard. When text is selected, it is immediately available - as the global mouse selection. The global mouse selection may - later be copied to the clipboard. By convention, the middle mouse - button is used to paste the global mouse selection. - - \i X11 also has the concept of ownership; if you change the - selection within a window, X11 will only notify the owner and the - previous owner of the change, i.e. it will not notify all - applications that the selection or clipboard data changed. - - \i Lastly, the X11 clipboard is event driven, i.e. the clipboard - will not function properly if the event loop is not running. - Similarly, it is recommended that the contents of the clipboard - are stored or retrieved in direct response to user-input events, - e.g. mouse button or key presses and releases. You should not - store or retrieve the clipboard contents in response to timer or - non-user-input events. - - \endlist - - \section2 Windows - - \list - - \i Microsoft Windows does not support the global mouse selection; - it only supports the global clipboard, e.g. Windows only adds text - to the clipboard when an explicit copy or cut is made. - - \i Windows does not have the concept of ownership; the clipboard - is a fully global resource so all applications are notified of - changes. - - \endlist - - See the multiclip example in the \e{TQt Designer} examples - directory for an example of a multiplatform clipboard application - that also demonstrates selection handling. -*/ - - -/*! - \internal - - Constructs a clipboard object. - - Do not call this function. - - Call TQApplication::clipboard() instead to get a pointer to the - application's global clipboard object. - - There is only one clipboard in the window system, and creating - more than one object to represent it is almost certainly an error. -*/ - -TQClipboard::TQClipboard( TQObject *parent, const char *name ) - : TQObject( parent, name ) -{ - // nothing -} - -#ifndef TQ_WS_WIN32 -/*! - \internal - - Destroys the clipboard. - - You should never delete the clipboard.
