\class QLineEdit |
|
128 |
\brief The QLineEdit widget is a one-line text editor. |
|
129 |
||
130 |
\ingroup basicwidgets |
|
131 |
||
132 |
||
133 |
A line edit allows the user to enter and edit a single line of |
|
134 |
plain text with a useful collection of editing functions, |
|
135 |
including undo and redo, cut and paste, and drag and drop. |
|
136 |
||
137 |
By changing the echoMode() of a line edit, it can also be used as |
|
138 |
a "write-only" field, for inputs such as passwords. |
|
139 |
||
140 |
The length of the text can be constrained to maxLength(). The text |
|
141 |
can be arbitrarily constrained using a validator() or an |
|
142 |
inputMask(), or both. |
|
143 |
||
144 |
A related class is QTextEdit which allows multi-line, rich text |
|
145 |
editing. |
|
146 |
||
147 |
You can change the text with setText() or insert(). The text is |
|
148 |
retrieved with text(); the displayed text (which may be different, |
|
149 |
see \l{EchoMode}) is retrieved with displayText(). Text can be |
|
150 |
selected with setSelection() or selectAll(), and the selection can |
|
151 |
be cut(), copy()ied and paste()d. The text can be aligned with |
|
152 |
setAlignment(). |
|
153 |
||
154 |
When the text changes the textChanged() signal is emitted; when |
|
155 |
the text changes other than by calling setText() the textEdited() |
|
156 |
signal is emitted; when the cursor is moved the |
|
157 |
cursorPositionChanged() signal is emitted; and when the Return or |
|
158 |
Enter key is pressed the returnPressed() signal is emitted. |
|
159 |
||
160 |
When editing is finished, either because the line edit lost focus |
|
161 |
or Return/Enter is pressed the editingFinished() signal is |
|
162 |
emitted. |
|
163 |
||
164 |
Note that if there is a validator set on the line edit, the |
|
165 |
returnPressed()/editingFinished() signals will only be emitted if |
|
166 |
the validator returns QValidator::Acceptable. |
|
167 |
||
168 |
By default, QLineEdits have a frame as specified by the Windows |
|
169 |
and Motif style guides; you can turn it off by calling |
|
170 |
setFrame(false). |
|
171 |
||
172 |
The default key bindings are described below. The line edit also |
|
173 |
provides a context menu (usually invoked by a right mouse click) |
|
174 |
that presents some of these editing options. |
|

194 |
\row \i Ctrl+X \i Deletes the selected text and copies it to the clipboard. |
|

\brief The validation input mask |
|
1189 |
||
1190 |
If no mask is set, inputMask() returns an empty string. |
|
1191 |
||
1192 |
Sets the QLineEdit's validation mask. Validators can be used |
|
1193 |
instead of, or in conjunction with masks; see setValidator(). |
|
1194 |
||
1195 |
Unset the mask and return to normal QLineEdit operation by passing |
|
1196 |
an empty string ("") or just calling setInputMask() with no |
|
1197 |
arguments. |
|
1198 |
||
1199 |
The table below shows the characters that can be used in an input mask. |
|
1200 |
A space character, the default character for a blank, is needed for cases |
|
1201 |
where a character is \e{permitted but not required}. |
|
1202 |
||
1203 |
\table |
|
1204 |
\header \i Character \i Meaning |
|
1205 |
\row \i \c A \i ASCII alphabetic character required. A-Z, a-z. |
|
1206 |
\row \i \c a \i ASCII alphabetic character permitted but not required. |
|
1207 |
\row \i \c N \i ASCII alphanumeric character required. A-Z, a-z, 0-9. |
|
1208 |
\row \i \c n \i ASCII alphanumeric character permitted but not required. |

1209 |
\row \i \c X \i Any character required. |
|
1210 |
\row \i \c x \i Any character permitted but not required. |
|
1211 |
\row \i \c 9 \i ASCII digit required. 0-9. |
|
1212 |
\row \i \c 0 \i ASCII digit permitted but not required. |
|
1213 |
\row \i \c D \i ASCII digit required. 1-9. |
|
1214 |
\row \i \c d \i ASCII digit permitted but not required (1-9). |
|
1215 |
\row \i \c # \i ASCII digit or plus/minus sign permitted but not required. |
|
1216 |
\row \i \c H \i Hexadecimal character required. A-F, a-f, 0-9. |
|
1217 |
\row \i \c h \i Hexadecimal character permitted but not required. |
|
1218 |
\row \i \c B \i Binary character required. 0-1. |
|
1219 |
\row \i \c b \i Binary character permitted but not required. |
|
1220 |
\row \i \c > \i All following alphabetic characters are uppercased. |
|
1221 |
\row \i \c < \i All following alphabetic characters are lowercased. |
|
1222 |
\row \i \c ! \i Switch off case conversion. |
|
1223 |
\row \i \tt{\\} \i Use \tt{\\} to escape the special |
|
1224 |
characters listed above to use them as |
|
1225 |
separators. |
|
1226 |
\endtable |
|
1227 |
||
1228 |
The mask consists of a string of mask characters and separators, |
|
1229 |
optionally followed by a semicolon and the character used for |
|
1230 |
blanks. The blank characters are always removed from the text |
|
1231 |
after editing. |
|
1232 |
||
1233 |

|
1234 |
\table |

\row \i \c 000.000.000.000;_ \i IP address; blanks are \c{_}. |
|
1237 |
\row \i \c HH:HH:HH:HH:HH:HH;_ \i MAC address |
|
1238 |
\row \i \c 0000-00-00 \i ISO Date; blanks are \c space |
|
1239 |
\row \i \c >AAAAA-AAAAA-AAAAA-AAAAA-AAAAA;# \i License number; |
|
1240 |
blanks are \c - and all (alphabetic) characters are converted to |
|
1241 |
uppercase. |
|
1242 |
\endtable |
|
1243 |
||
1244 |
To get range control (e.g., for an IP address) use masks together |

with \link setValidator() validators\endlink. |
