Detailed Description

The QLineEdit widget is a one-line text editor.

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. When switching between a validator and an input mask on the same line edit, it is best to clear the validator or input mask to prevent undefined behavior.

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 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, QLineEdits 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.

Property Documentation

new bool QtGui.QLineEdit.AcceptableInput

get

This property holds whether the input satisfies the inputMask and the validator.

By default, this property is true.

new Qt.AlignmentFlag QtGui.QLineEdit.Alignment

getset

This property holds the alignment of the line edit.

Both horizontal and vertical alignment is allowed here, Qt::AlignJustify will map to Qt::AlignLeft.

By default, this property contains a combination of Qt::AlignLeft and Qt::AlignVCenter.

new QCompleter QtGui.QLineEdit.Completer

getset

Returns the current QCompleter that provides completions.

This function was introduced in Qt 4.2.

Sets this line edit to provide auto completions from the completer, c. The completion mode is set using QCompleter::setCompletionMode().

To use a QCompleter with a QValidator or QLineEdit::inputMask, you need to ensure that the model provided to QCompleter contains valid entries. You can use the QSortFilterProxyModel to ensure that the QCompleter's model contains only valid entries.

If c == 0, setCompleter() removes the current completer, effectively disabling auto completion.

This function was introduced in Qt 4.2.

new Qt.CursorMoveStyle QtGui.QLineEdit.CursorMoveStyle

getset

This property holds the movement style of cursor in this line edit.

When this property is set to Qt::VisualMoveStyle, the line edit will use visual movement style. Pressing the left arrow key will always cause the cursor to move left, regardless of the text's writing direction. The same behavior applies to right arrow key.

When the property is Qt::LogicalMoveStyle (the default), within a LTR text block, increase cursor position when pressing left arrow key, decrease cursor position when pressing the right arrow key. If the text block is right to left, the opposite behavior applies.

This property was introduced in Qt 4.8.

new int QtGui.QLineEdit.CursorPosition

getset

This property holds the current cursor position for this line edit.

Setting the cursor position causes a repaint when appropriate.

By default, this property contains a value of 0.

Slot<System.Int32,System.Int32> QtGui.QLineEdit.CursorPositionChanged

addremove

This signal is emitted whenever the cursor moves. The previous position is given by old, and the new position by new.

See also setCursorPosition() and cursorPosition().

new string QtGui.QLineEdit.DisplayText

get

This property holds the displayed text.

If echoMode is Normal this returns the same as text(); if EchoMode is Password or PasswordEchoOnEdit it returns a string of asterisks text().length() characters long, e.g. "******"; if EchoMode is NoEcho returns an empty string, "".

By default, this property contains an empty string.

new bool QtGui.QLineEdit.DragEnabled

getset

This property holds whether the lineedit starts a drag if the user presses and moves the mouse on some selected text.

Dragging is disabled by default.

new EchoMode QtGui.QLineEdit.echoMode

getset

This property holds the line edit's echo mode.

The echo mode determines how the text entered in the line edit is displayed (or echoed) to the user.

The most common setting is Normal, in which the text entered by the user is displayed verbatim, but QLineEdit also supports modes that allow the entered text to be suppressed or obscured: these include NoEcho, Password and PasswordEchoOnEdit.

The widget's display and the ability to copy or drag the text is affected by this setting.

By default, this property is set to Normal.

Slot QtGui.QLineEdit.EditingFinished

addremove

This signal is emitted when the Return or Enter key is pressed or the line edit loses focus. Note that if there is a validator() or inputMask() set on the line edit and enter/return is pressed, the editingFinished() signal will only be emitted if the input follows the inputMask() and the validator() returns QValidator::Acceptable.

new IQLineEditSignals QtGui.QLineEdit.Emit

getprotected

new bool QtGui.QLineEdit.Frame

getset

This property holds whether the line edit draws itself with a frame.

If enabled (the default) the line edit draws itself inside a frame, otherwise the line edit draws itself without any frame.

new bool QtGui.QLineEdit.HasSelectedText

get

This property holds whether there is any text selected.

hasSelectedText() returns true if some or all of the text has been selected by the user; otherwise returns false.

By default, this property is false.

new string QtGui.QLineEdit.InputMask

getset

This property holds the validation input mask.

If no mask is set, inputMask() returns an empty string.

Sets the QLineEdit's validation mask. Validators can be used instead of, or in conjunction with masks; see setValidator().

Unset the mask and return to normal QLineEdit operation by passing an empty string ("") or just calling setInputMask() with no arguments.

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 permitted but not required.

CharacterMeaning

A ASCII alphabetic character required. A-Z, a-z.

a ASCII alphabetic character permitted but not required.

N ASCII alphanumeric character required. A-Z, a-z, 0-9.

n ASCII alphanumeric character permitted but not required.

X Any character required.

x Any character permitted but not required.

9 ASCII digit required. 0-9.

0 ASCII digit permitted but not required.

D ASCII digit required. 1-9.

d ASCII digit permitted but not required (1-9).

# ASCII digit or plus/minus sign permitted but not required.

H Hexadecimal character required. A-F, a-f, 0-9.

h Hexadecimal character permitted but not required.

B Binary character required. 0-1.

b Binary character permitted but not required.

> All following alphabetic characters are uppercased.

< All following alphabetic characters are lowercased.

! Switch off case conversion.

\ Use \ to escape the special characters listed above to use them as separators.

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:

MaskNotes

000.000.000.000;_ IP address; blanks are _.

HH:HH:HH:HH:HH:HH;_ MAC address

0000-00-00 ISO Date; blanks are space

>AAAAA-AAAAA-AAAAA-AAAAA-AAAAA;# License number; blanks are - and all (alphabetic) characters are converted to uppercase.

To get range control (e.g., for an IP address) use masks together with validators.

Slot QtGui.QLineEdit.LostFocus

addremove

new int QtGui.QLineEdit.MaxLength

getset

This property holds the maximum permitted length of the text.

If the text is too long, it is truncated at the limit.

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.

If the line edit has an input mask, the mask defines the maximum string length.

By default, this property contains a value of 32767.

new bool QtGui.QLineEdit.Modified

getset

This property holds whether the line edit's contents has been modified by the user.

The modified flag is never read by QLineEdit; it has a default value of false and is changed to true whenever the user changes the line edit's contents.

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.

Calling setText() resets the modified flag to false.

new string QtGui.QLineEdit.PlaceholderText

getset

This property holds the line edit's placeholder text.

Setting this property makes the line edit display a grayed-out placeholder text as long as the text() is empty and the widget doesn't have focus.

By default, this property contains an empty string.

This property was introduced in Qt 4.7.

new bool QtGui.QLineEdit.ReadOnly

getset

This property holds whether the line edit is read only.

In read-only mode, the user can still copy the text to the clipboard, or drag and drop the text (if echoMode() is Normal), but cannot edit it.

QLineEdit does not show a cursor in read-only mode.

By default, this property is false.

new bool QtGui.QLineEdit.RedoAvailable

get

This property holds whether redo is available.

Redo becomes available once the user has performed one or more undo operations on text in the line edit.

By default, this property is false.

Slot QtGui.QLineEdit.ReturnPressed

addremove

This signal is emitted when the Return or Enter key is pressed. Note that if there is a validator() or inputMask() set on the line edit, the returnPressed() signal will only be emitted if the input follows the inputMask() and the validator() returns QValidator::Acceptable.

new string QtGui.QLineEdit.SelectedText

get

This property holds the selected text.

If there is no selected text this property's value is an empty string.

By default, this property contains an empty string.

Slot QtGui.QLineEdit.SelectionChanged

addremove

This signal is emitted whenever the selection changes.

See also hasSelectedText() and selectedText().

new QMetaObject QtGui.QLineEdit.StaticMetaObject

staticget

new string QtGui.QLineEdit.Text

getset

This property holds the line edit's text.

Setting this property clears the selection, clears the undo/redo history, moves the cursor to the end of the line and resets the modified property to false. The text is not validated when inserted with setText().

The text is truncated to maxLength() length.

By default, this property contains an empty string.

Slot<System.String> QtGui.QLineEdit.TextChanged

addremove

This signal is emitted whenever the text changes. The text argument is the new text.

Unlike textEdited(), this signal is also emitted when the text is changed programmatically, for example, by calling setText().

Slot<System.String> QtGui.QLineEdit.TextEdited

addremove

This signal is emitted whenever the text is edited. The text argument is the new text.

Unlike textChanged(), this signal is not emitted when the text is changed programmatically, for example, by calling setText().

new QMargins QtGui.QLineEdit.TextMargins

getset

Returns the widget's text margins.

This function was introduced in Qt 4.6.

Sets the margins around the text inside the frame.

This function was introduced in Qt 4.6.

new bool QtGui.QLineEdit.UndoAvailable

get

This property holds whether undo is available.

Undo becomes available once the user has modified the text in the line edit.

By default, this property is false.

new QValidator QtGui.QLineEdit.Validator

getset

Returns a pointer to the current input validator, or 0 if no validator has been set.

Sets this line edit to only accept input that the validator, v, will accept. This allows you to place any arbitrary constraints on the text which may be entered.

If v == 0, setValidator() removes the current input validator. The initial setting is to have no input validator (i.e. any input is accepted up to maxLength()).
