The text - can be arbitrarily constrained using a validator() or an - inputMask(), or both. - - A related class is TQTextEdit which allows multi-line, rich-text - editing. - - You can change the text with setText() or insert(). The text is - retrieved with text(); the displayed text (which may be different, - see \l{EchoMode}) is retrieved with displayText(). Text can be - selected with setSelection() or selectAll(), and the selection can - be cut(), copy()ied and paste()d. The text can be aligned with - tqsetAlignment(). - - When the text changes the textChanged() signal is emitted; when - the Return or Enter key is pressed the returnPressed() signal is - emitted. Note that if there is a validator set on the line edit, - the returnPressed() signal will only be emitted if the validator - returns \c Acceptable. - - By default, TQLineEdits have a frame as specified by the Windows - and Motif style guides; you can turn it off by calling - setFrame(FALSE). - - The default key bindings are described below. The line edit also - provides a context menu (usually invoked by a right mouse click) - that presents some of these editing options. - \target desc - \table - \header \i Keypress \i Action - \row \i Left Arrow \i Moves the cursor one character to the left. - \row \i Shift+Left Arrow \i Moves and selects text one character to the left. - \row \i Right Arrow \i Moves the cursor one character to the right. - \row \i Shift+Right Arrow \i Moves and selects text one character to the right. - \row \i Home \i Moves the cursor to the beginning of the line. - \row \i End \i Moves the cursor to the end of the line. - \row \i Backspace \i Deletes the character to the left of the cursor. - \row \i Ctrl+Backspace \i Deletes the word to the left of the cursor. - \row \i Delete \i Deletes the character to the right of the cursor. - \row \i Ctrl+Delete \i Deletes the word to the right of the cursor. - \row \i Ctrl+A \i Moves the cursor to the beginning of the line. - \row \i Ctrl+B \i Moves the cursor one character to the left. - \row \i Ctrl+C \i Copies the selected text to the clipboard. - (Windows also supports Ctrl+Insert for this operation.) - \row \i Ctrl+D \i Deletes the character to the right of the cursor. - \row \i Ctrl+E \i Moves the cursor to the end of the line. - \row \i Ctrl+F \i Moves the cursor one character to the right. - \row \i Ctrl+H \i Deletes the character to the left of the cursor. - \row \i Ctrl+K \i Deletes to the end of the line. - \row \i Ctrl+V \i Pastes the clipboard text into line edit. - (Windows also supports Shift+Insert for this operation.) - \row \i Ctrl+X \i Deletes the selected text and copies it to the clipboard. - (Windows also supports Shift+Delete for this operation.) - \row \i Ctrl+Z \i Undoes the last operation. - \row \i Ctrl+Y \i Redoes the last undone operation. - \endtable - - Any other key sequence that represents a valid character, will - cause the character to be inserted into the line edit. - - <img src=qlined-m.png> <img src=qlined-w.png> - - \sa TQTextEdit TQLabel TQComboBox - \link guibooks.html#fowler GUI Design Handbook: Field, Entry\endlink -*/ - - -/*! - \fn void TQLineEdit::textChanged( const TQString& ) - - This signal is emitted whenever the text changes.
