< hr > < a name = "details" > < / a > < h2 > Detailed Description< / h2 >
The TQLineEdit widget is a one-line text editor.
< p >
< p > 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.
< p > By changing the < a href = "#echoMode" > echoMode< / a > () of a line edit, it can also be used as
a "write-only" field, for inputs such as passwords.
< p > The length of the text can be constrained to < a href = "#maxLength" > maxLength< / a > (). The text
can be arbitrarily constrained using a < a href = "#validator" > validator< / a > () or an
< a href = "#inputMask" > inputMask< / a > (), or both.
< p > A related class is < a href = "tqtextedit.html" > TQTextEdit< / a > which allows multi-line, rich-text
editing.
< p > You can change the text with < a href = "#setText" > setText< / a > () or < a href = "#insert" > insert< / a > (). The text is
retrieved with < a href = "#text" > text< / a > (); the displayed text (which may be different,
see < a href = "#EchoMode-enum" > EchoMode< / a > ) is retrieved with < a href = "#displayText" > displayText< / a > (). Text can be
selected with < a href = "#setSelection" > setSelection< / a > () or < a href = "#selectAll" > selectAll< / a > (), and the selection can
be < a href = "#cut" > cut< / a > (), < a href = "#copy" > copy< / a > ()ied and < a href = "#paste" > paste< / a > ()d. The text can be aligned with
< a href = "#setAlignment" > setAlignment< / a > ().
< p > When the text changes the < a href = "#textChanged" > textChanged< / a > () signal is emitted; when
the Return or Enter key is pressed the < a href = "#returnPressed" > returnPressed< / a > () 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 < tt > Acceptable< / tt > .
< p > By default, TQLineEdits have a frame as specified by the Windows
and < a href = "motif-extension.html#Motif" > Motif< / a > style guides; you can turn it off by calling
< a href = "#setFrame" > setFrame< / a > (FALSE).
< p > 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.

This function is called to create the popup menu which is shown

< p > The mask consists of a string of mask characters and separators,
optionally followed by a semi-colon and the character used for
blanks: the blank characters are always removed from the text
after editing. The default blank character is space.
< p > Examples:
< center > < table cellpadding = "4" cellspacing = "2" border = "0" >
< tr bgcolor = "#a2c511" > < th valign = "top" > Mask < th valign = "top" > Notes
< tr bgcolor = "#d0d0d0" > < td valign = "top" > < tt > 000.000.000.000;_< / tt > < td valign = "top" > IP address; blanks are < tt > _< / tt > .
< tr bgcolor = "#f0f0f0" > < td valign = "top" > < tt > 0000-00-00< / tt > < td valign = "top" > ISO Date; blanks are < tt > space< / tt >
< tr bgcolor = "#d0d0d0" > < td valign = "top" > < tt > > AAAAA-AAAAA-AAAAA-AAAAA-AAAAA;#< / tt > < td valign = "top" > License number;
blanks are < tt > -< / tt > and all (alphabetic) characters are converted to
uppercase.
< / table > < / center >
< p > To get range control (e.g. for an IP address) use masks together
with < a href = "#setValidator" > validators< / a > .
< p > < p > See also < a href = "#maxLength-prop" > maxLength< / a > .
< p > Set this property's value with < a href = "#setInputMask" > setInputMask< / a > () and get this property's value with < a href = "#inputMask" > inputMask< / a > ().
< h3 class = fn > int < a name = "maxLength-prop" > < / a > maxLength< / h3 >
< p > This property holds the maximum permitted length of the text.
< p > If the text is too long, it is truncated at the limit.
< p > If truncation occurs any selected text will be unselected, the
cursor position is set to 0 and the first part of the string is
shown.
< p > If the line edit has an input mask, the mask defines the maximum
string length.
< p > < p > See also < a href = "#inputMask-prop" > inputMask< / a > .
< p > Set this property's value with < a href = "#setMaxLength" > setMaxLength< / a > () and get this property's value with < a href = "#maxLength" > maxLength< / a > ().
< h3 class = fn > bool < a name = "modified-prop" > < / a > modified< / h3 >
< p > This property holds whether the line edit's contents has been modified by the user.
< p > The modified flag is never read by TQLineEdit; it has a default value
of FALSE and is changed to TRUE whenever the user changes the line
edit's contents.
< p > This is useful for things that need to provide a default value but
do not start out knowing what the default should be (perhaps it
depends on other fields on the form). Start the line edit without
the best default, and when the default is known, if modified()
returns FALSE (the user hasn't entered any text), insert the
default value.
< p > Calling < a href = "#clearModified" > clearModified< / a > () or < a href = "#setText" > setText< / a > () resets the modified flag to
FALSE.
< p > Get this property's value with < a href = "#isModified" > isModified< / a > ().
< h3 class = fn > bool < a name = "readOnly-prop" > < / a > readOnly< / h3 >
< p > This property holds whether the line edit is read only.
< p > In read-only mode, the user can still copy the text to the
clipboard or drag-and-drop the text (if < a href = "#echoMode" > echoMode< / a > () is < a href = "#EchoMode-enum" > Normal< / a > ),
but cannot edit it.
< p > TQLineEdit does not show a cursor in read-only mode.
< p > < p > See also < a href = "tqwidget.html#enabled-prop" > enabled< / a > .
< p > Set this property's value with < a href = "#setReadOnly" > setReadOnly< / a > () and get this property's value with < a href = "#isReadOnly" > isReadOnly< / a > ().
< h3 class = fn > bool < a name = "redoAvailable-prop" > < / a > redoAvailable< / h3 >
< p > This property holds whether redo is available.
< p >
< p > Get this property's value with < a href = "#isRedoAvailable" > isRedoAvailable< / a > ().
< h3 class = fn > < a href = "tqstring.html" > TQString< / a > < a name = "selectedText-prop" > < / a > selectedText< / h3 >
< p > This property holds the selected text.
< p > If there is no selected text this property's value is
< a href = "tqstring.html#TQString-null" > TQString::null< / a > .
< p > < p > See also < a href = "#hasSelectedText-prop" > hasSelectedText< / a > .
< p > Get this property's value with < a href = "#selectedText" > selectedText< / a > ().
< h3 class = fn > < a href = "tqstring.html" > TQString< / a > < a name = "text-prop" > < / a > text< / h3 >
< p > This property holds the line edit's text.
< p > Note that setting this property clears the selection, clears the
undo/redo history, moves the cursor to the end of the line and
resets the < a href = "#modified-prop" > modified< / a > property to FALSE. The text is not
validated when inserted with < a href = "#setText" > setText< / a > ().
< p > The text is truncated to < a href = "#maxLength" > maxLength< / a > () length.
< p > < p > See also < a href = "#insert" > insert< / a > ().
< p > Set this property's value with < a href = "#setText" > setText< / a > () and get this property's value with < a href = "#text" > text< / a > ().
< h3 class = fn > bool < a name = "undoAvailable-prop" > < / a > undoAvailable< / h3 >
< p > This property holds whether undo is available.
< p >
< p > Get this property's value with < a href = "#isUndoAvailable" > isUndoAvailable< / a > ().
