![]() Note: The pointer returned might become invalidated when the contents of the clipboard changes either by calling one of the setter functions or externally by the system clipboard changing. The text(), image(), and pixmap() functions are simpler wrappers for retrieving text, image, and pixmap data. If mode is QClipboard::FindBuffer, the data is retrieved from the search string buffer. If mode is QClipboard::Selection, the data is retrieved from the global mouse selection. If mode is QClipboard::Clipboard, the data is retrieved from the global clipboard. The mode argument is used to control which part of the system clipboard is used. Returns a pointer to a QMimeData representation of the current clipboard data (can be nullptr if the given mode is not supported by the platform). const QMimeData *QClipboard:: mimeData( QClipboard::Mode mode = Clipboard) const See also setImage(), pixmap(), mimeData(), and QImage::isNull(). If mode is QClipboard::Selection, the image is retrieved from the global mouse selection. If mode is QClipboard::Clipboard, the image is retrieved from the global clipboard. Returns the clipboard image, or returns a null image if the clipboard does not contain an image or if it contains an image in an unsupported image format. QImage QClipboard:: image( QClipboard::Mode mode = Clipboard) const See also QClipboard::Mode and supportsSelection(). If mode is QClipboard::FindBuffer, this function clears the search string buffer. If mode is QClipboard::Selection, this function clears the global mouse selection contents. If mode is QClipboard::Clipboard, this function clears the global clipboard contents. void QClipboard:: clear( QClipboard::Mode mode = Clipboard) See also dataChanged(), findBufferChanged(), and changed(). Windows and macOS don't support selections. This only applies to windowing systems that support selections, e.g. This signal is emitted when the selection is changed. See also dataChanged(), selectionChanged(), and changed(). ![]() With Qt version 4.3 or higher, clipboard changes made by other applications will only be detected when the application is activated. This signal is emitted when the find buffer is changed. See also findBufferChanged(), selectionChanged(), and changed(). On macOS and with Qt version 4.3 or higher, clipboard changes made by other applications will only be detected when the application is activated. This signal is emitted when the clipboard data is changed. See also dataChanged(), selectionChanged(), and findBufferChanged(). This signal is emitted when the data for the given clipboard mode is changed. Member Function Documentation void QClipboard:: changed( QClipboard::Mode mode) On Android only these mime types are supported: text/plain, text/html, and text/uri-list. Windows and macOS does not have the concept of ownership the clipboard is a fully global resource so all applications are notified of changes.they only add text to the clipboard when an explicit copy or cut is made. Windows and macOS do not support the global mouse selection they only supports the global clipboard, i.e.This find clipboard can be accessed by specifying the FindBuffer mode. MacOS supports a separate find buffer that holds the current search string in Find operations. For instance, Nautilus expects files to be supplied with a x-special/gnome-copied-files MIME type with data beginning with the cut/copy action, a newline character, and the URL of the file. Since there is no standard way to copy and paste files between applications on X11, various MIME types and conventions are currently in use.You should not store or retrieve the clipboard contents in response to timer or non-user-input events. mouse button or key presses and releases. Similarly, it is recommended that the contents of the clipboard are stored or retrieved in direct response to user-input events, e.g. the clipboard will not function properly if the event loop is not running. Lastly, the X11 clipboard is event driven, i.e.it will not notify all applications that the selection or clipboard data changed. 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.By convention, the middle mouse button is used to paste the global mouse selection. The global mouse selection may later be copied to the clipboard. When text is selected, it is immediately available as the global mouse selection. The X11 Window System has the concept of a separate selection and clipboard.SetPixmap(qvariant_cast (mimeData - >imageData())) Const QClipboard *clipboard = QApplication ::clipboard() Ĭonst QMimeData *mimeData = clipboard - >mimeData()
