\class QSecureLineEdit
\brief The QSecureLineEdit widget is a one-line text editor.
\ingroup basicwidgets
\mainclass
A line edit allows the user to enter and edit a single line of
plain text with a useful collection of editing functions,
including undo and redo, cut and paste, and drag and drop.
By changing the echoMode() of a line edit, it can also be used as
a "write-only" field, for inputs such as passwords.
The length of the text can be constrained to maxLength(). The text
can be arbitrarily constrained using a validator() or an
inputMask(), or both.
A related class is QTextEdit 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
setAlignment().
When the text changes the textChanged() signal is emitted; when
the text changes other than by calling setText() the textEdited()
signal is emitted; when the cursor is moved the
cursorPositionChanged() signal is emitted; and when the Return or
Enter key is pressed the returnPressed() signal is emitted.
When editing is finished, either because the line edit lost focus
or Return/Enter is pressed the editingFinished() signal is
emitted.
Note that if there is a validator set on the line edit, the
returnPressed()/editingFinished() signals will only be emitted if
the validator returns QValidator::Acceptable.
By default, QSecureLineEdits 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

\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 Select all.
\row \i Ctrl+C \i Copies the selected text to the clipboard.
\row \i Ctrl+Insert \i Copies the selected text to the clipboard.
\row \i Ctrl+K \i Deletes to the end of the line.
\row \i Ctrl+V \i Pastes the clipboard text into line edit.
\row \i Shift+Insert \i Pastes the clipboard text into line edit.
\row \i Ctrl+X \i Deletes the selected text and copies it to the clipboard.
\row \i Shift+Delete \i Deletes the selected text and copies it to the clipboard.
\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.

The table below shows the characters that can be used in an input mask.
A space character, the default character for a blank, is needed for cases
where a character is \e{permitted but not required}.
\table
\header \i Character \i Meaning
\row \i \c A \i ASCII alphabetic character required. A-Z, a-z.
\row \i \c a \i ASCII alphabetic character permitted but not required.
\row \i \c N \i ASCII alphanumeric character required. A-Z, a-z, 0-9.
\row \i \c n \i ASCII alphanumeric character permitted but not required.
\row \i \c X \i Any character required.
\row \i \c x \i Any character permitted but not required.
\row \i \c 9 \i ASCII digit required. 0-9.
\row \i \c 0 \i ASCII digit permitted but not required.
\row \i \c D \i ASCII digit required. 1-9.
\row \i \c d \i ASCII digit permitted but not required (1-9).
\row \i \c # \i ASCII digit or plus/minus sign permitted but not required.
\row \i \c H \i Hexadecimal character required. A-F, a-f, 0-9.
\row \i \c h \i Hexadecimal character permitted but not required.
\row \i \c B \i Binary character required. 0-1.
\row \i \c b \i Binary character permitted but not required.
\row \i \c > \i All following alphabetic characters are uppercased.
\row \i \c < \i All following alphabetic characters are lowercased.
\row \i \c ! \i Switch off case conversion.
\row \i \tt{\\} \i Use \tt{\\} to escape the special
characters listed above to use them as
separators.
\endtable
The mask consists of a string of mask characters and separators,
optionally followed by a semicolon and the character used for
blanks. The blank characters are always removed from the text
after editing.
Examples:
\table
\header \i Mask \i Notes
\row \i \c 000.000.000.000;_ \i IP address; blanks are \c{_}.
\row \i \c HH:HH:HH:HH:HH:HH;_ \i MAC address
\row \i \c 0000-00-00 \i ISO Date; blanks are \c space
\row \i \c >AAAAA-AAAAA-AAAAA-AAAAA-AAAAA;# \i License number;
blanks are \c - and all (alphabetic) characters are converted to
uppercase.
\endtable
To get range control (e.g. for an IP address) use masks together
with \link setValidator() validators\endlink.
