|

137 | \brief The QLineEdit widget is a one-line text editor.
|
---|
138 |
|
---|
139 | \ingroup basicwidgets
|
---|
140 | \mainclass
|
---|
141 |
|
---|
142 | A line edit allows the user to enter and edit a single line of
|
---|
143 | plain text with a useful collection of editing functions,
|
---|
144 | including undo and redo, cut and paste, and drag and drop.
|
---|
145 |
|
---|
146 | By changing the echoMode() of a line edit, it can also be used as
|
---|
147 | a "write-only" field, for inputs such as passwords.
|
---|
148 |
|
---|
149 | The length of the text can be constrained to maxLength(). The text
|
---|
150 | can be arbitrarily constrained using a validator() or an
|
---|
151 | inputMask(), or both.
|
---|
152 |
|
---|
153 | A related class is QTextEdit which allows multi-line, rich text
|
---|
154 | editing.
|
---|
155 |
|
---|
156 | You can change the text with setText() or insert(). The text is
|
---|
157 | retrieved with text(); the displayed text (which may be different,
|
---|
158 | see \l{EchoMode}) is retrieved with displayText(). Text can be
|
---|
159 | selected with setSelection() or selectAll(), and the selection can
|
---|
160 | be cut(), copy()ied and paste()d. The text can be aligned with
|
---|
161 | setAlignment().
|
---|
162 |
|
---|
163 | When the text changes the textChanged() signal is emitted; when
|
---|
164 | the text changes other than by calling setText() the textEdited()
|
---|
165 | signal is emitted; when the cursor is moved the
|
---|
166 | cursorPositionChanged() signal is emitted; and when the Return or
|
---|
167 | Enter key is pressed the returnPressed() signal is emitted.
|
---|
168 |
|
---|
169 | When editing is finished, either because the line edit lost focus
|
---|
170 | or Return/Enter is pressed the editingFinished() signal is
|
---|
171 | emitted.
|
---|
172 |
|
---|
173 | Note that if there is a validator set on the line edit, the
|
---|
174 | returnPressed()/editingFinished() signals will only be emitted if
|
---|
175 | the validator returns QValidator::Acceptable.
|
---|
176 |
|
---|
177 | By default, QLineEdits have a frame as specified by the Windows
|
---|
178 | and Motif style guides; you can turn it off by calling
|
---|
179 | setFrame(false).
|
---|
180 |
|
---|
181 | The default key bindings are described below. The line edit also
|
---|
182 | provides a context menu (usually invoked by a right mouse click)
|
---|
183 | that presents some of these editing options.
