#include <ntqclipboard.h>
Inherits TQObject.
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 the drag-and-drop documentation.
There is a single TQClipboard object in an application, and you can access it using TQApplication::clipboard().
Example:
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 );
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().
See the multiclip example in the TQt Designer examples directory for an example of a multiplatform clipboard application that also demonstrates selection handling.

This enum type is used to control which part of the system clipboard is used by TQClipboard::data(), TQClipboard::setData() and related functions.
Note: Support for Selection is provided only on systems with a global mouse selection (e.g. X11).
See also TQClipboard::supportsSelection().
The mode argument is used to control which part of the system clipboard is used. If mode is TQClipboard::Clipboard, this function clears the the global clipboard contents. If mode is TQClipboard::Selection, this function clears the global mouse selection contents.
See also TQClipboard::Mode and supportsSelection().
This function uses the TQClipboard::clear() function which takes a TQClipboard::Mode argument. The value of the mode argument is determined by the return value of selectionModeEnabled(). If selectionModeEnabled() returns TRUE, the mode argument is TQClipboard::Selection, otherwise the mode argument is TQClipboard::Clipboard.
The mode argument is used to control which part of the system clipboard is used. If mode is TQClipboard::Clipboard, the data is retrieved from the global clipboard. If mode is TQClipboard::Selection, the data is retrieved from the global mouse selection.
See also setData().
This function uses the TQClipboard::data() function which takes a TQClipboard::Mode argument. The value of the mode argument is determined by the return value of selectionModeEnabled(). If selectionModeEnabled() returns TRUE, the mode argument is TQClipboard::Selection, otherwise the mode argument is TQClipboard::Clipboard.
This signal is emitted when the clipboard data is changed.
The mode argument is used to control which part of the system clipboard is used. If mode is TQClipboard::Clipboard, the image is retrieved from the global clipboard. If mode is TQClipboard::Selection, the image is retrieved from the global mouse selection.
See also setImage(), pixmap(), data(), and TQImage::isNull().
This function uses the TQClipboard::image() function which takes a TQClipboard::Mode argument. The value of the mode argument is determined by the return value of selectionModeEnabled(). If selectionModeEnabled() returns TRUE, the mode argument is TQClipboard::Selection, otherwise the mode argument is TQClipboard::Clipboard.
The mode argument is used to control which part of the system clipboard is used. If mode is TQClipboard::Clipboard, the pixmap is retrieved from the global clipboard. If mode is TQClipboard::Selection, the pixmap is retrieved from the global mouse selection.
See also setPixmap(), image(), data(), and TQPixmap::convertFromImage().
This function uses the TQClipboard::pixmap() function which takes a TQClipboard::Mode argument. The value of the mode argument is determined by the return value of selectionModeEnabled(). If selectionModeEnabled() returns TRUE, the mode argument is TQClipboard::Selection, otherwise the mode argument is TQClipboard::Clipboard.
This signal is emitted when the selection is changed. This only applies to windowing systems that support selections, e.g. X11. Windows doesn't support selections.
Use the TQClipboard::data(), TQClipboard::setData() and related functions which take a TQClipboard::Mode argument.
Returns the selection mode.
See also setSelectionMode() and supportsSelection().
The mode argument is used to control which part of the system clipboard is used. If mode is TQClipboard::Clipboard, the data is retrieved from the global clipboard. If mode is TQClipboard::Selection, the data is retrieved from the global mouse selection.
The TQDragObject subclasses are reasonable objects to put into the clipboard (but do not try to call TQDragObject::drag() on the same object). Any TQDragObject placed in the clipboard should have a parent of 0. Do not put TQDragMoveEvent or TQDropEvent subclasses in the clipboard, as they do not belong to the event handler which receives them.
The setText(), setImage() and setPixmap() functions are simpler wrappers for setting text, image and pixmap data respectively.
See also data().
This function uses the TQClipboard::setData() function which takes a TQClipboard::Mode argument. The value of the mode argument is determined by the return value of selectionModeEnabled(). If selectionModeEnabled() returns TRUE, the mode argument is TQClipboard::Selection, otherwise the mode argument is TQClipboard::Clipboard.
The mode argument is used to control which part of the system clipboard is used. If mode is TQClipboard::Clipboard, the image is stored in the global clipboard. If mode is TQClipboard::Selection, the data is stored in the global mouse selection.
This is shorthand for:
setData( new TQImageDrag(image), mode )
See also image(), setPixmap(), and setData().
This function uses the TQClipboard::setImage() function which takes a TQClipboard::Mode argument. The value of the mode argument is determined by the return value of selectionModeEnabled(). If selectionModeEnabled() returns TRUE, the mode argument is TQClipboard::Selection, otherwise the mode argument is TQClipboard::Clipboard.
The mode argument is used to control which part of the system clipboard is used. If mode is TQClipboard::Clipboard, the pixmap is stored in the global clipboard. If mode is TQClipboard::Selection, the pixmap is stored in the global mouse selection.
See also pixmap(), setImage(), and setData().
This function uses the TQClipboard::setPixmap() function which takes a TQClipboard::Mode argument. The value of the mode argument is determined by the return value of selectionModeEnabled(). If selectionModeEnabled() returns TRUE, the mode argument is TQClipboard::Selection, otherwise the mode argument is TQClipboard::Clipboard.
Use the TQClipboard::data(), TQClipboard::setData() and related functions which take a TQClipboard::Mode argument.
Sets the clipboard selection mode. If enable is TRUE, then subsequent calls to TQClipboard::setData() and other functions which put data into the clipboard will put the data into the mouse selection, otherwise the data will be put into the clipboard.
See also supportsSelection() and selectionModeEnabled().
The mode argument is used to control which part of the system clipboard is used. If mode is TQClipboard::Clipboard, the text is stored in the global clipboard. If mode is TQClipboard::Selection, the text is stored in the global mouse selection.
See also text() and setData().
Example: regexptester/regexptester.cpp.
This function uses the TQClipboard::setText() function which takes a TQClipboard::Mode argument. The value of the mode argument is determined by the return value of selectionModeEnabled(). If selectionModeEnabled() returns TRUE, the mode argument is TQClipboard::Selection, otherwise the mode argument is TQClipboard::Clipboard.
Example: regexptester/regexptester.cpp.
The mode argument is used to control which part of the system clipboard is used. If mode is TQClipboard::Clipboard, the text is retrieved from the global clipboard. If mode is TQClipboard::Selection, the text is retrieved from the global mouse selection.
See also setText(), data(), and TQString::operator!().
Returns the clipboard text in subtype subtype, or a null string if the clipboard does not contain any text. If subtype is null, any subtype is acceptable, and subtype is set to the chosen subtype.
The mode argument is used to control which part of the system clipboard is used. If mode is TQClipboard::Clipboard, the text is retrieved from the global clipboard. If mode is TQClipboard::Selection, the text is retrieved from the global mouse selection.
Common values for subtype are "plain" and "html".
See also setText(), data(), and TQString::operator!().
This function uses the TQClipboard::text() function which takes a TQClipboard::Mode argument. The value of the mode argument is determined by the return value of selectionModeEnabled(). If selectionModeEnabled() returns TRUE, the mode argument is TQClipboard::Selection, otherwise the mode argument is TQClipboard::Clipboard.
Returns the clipboard text in subtype subtype, or a null string if the clipboard does not contain any text. This function uses the TQClipboard::text() function which takes a TQClipboard::Mode argument. The value of the mode argument is determined by the return value of selectionModeEnabled(). If selectionModeEnabled() returns TRUE, the mode argument is TQClipboard::Selection, otherwise the mode argument is TQClipboard::Clipboard.
