cursorPositionChanged ( arg_1, arg_2 ) ¶ Parameters Returns the cursor position under the point pos. Setting the cursor position causes a repaint when appropriate.īy default, this property contains a value of 0. This property holds the current cursor position for this line edit. If the text block is right to left, the opposite behavior applies. When the property is 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. The same behavior applies to right arrow key. Pressing the left arrow key will always cause the cursor to move left, regardless of the text’s writing direction. When this property is set to VisualMoveStyle, the line edit will use visual movement style. This property holds the movement style of cursor in this line edit. Pastes the clipboard text into line edit.ĭeletes the selected text and copies it to the clipboard.Īny other key sequence that represents a valid character, will cause the character to be inserted into the line edit.ĬursorBackward().

Moves and selects text one character to the right. Moves the cursor one character to the right. Moves and selects text one character to the left. Moves the cursor one character to the left. The line edit also provides a context menu (usually invoked by a right mouse click) that presents some of these editing options. The default key bindings are described below. īy default, QLineEdits have a frame as specified by platform style guides you can turn it off by calling setFrame (false). Note that if there is a validator set on the line edit, the returnPressed() / editingFinished() signals will only be emitted if the validator returns Acceptable. When editing is finished, either because the line edit lost focus or Return/Enter is pressed the editingFinished() signal is emitted. 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. The text can be aligned with setAlignment(). Text can be selected with setSelection() or selectAll(), and the selection can be cut(), copy() ied and paste() d. The text is retrieved with text() the displayed text (which may be different, see EchoMode ) is retrieved with displayText(). You can change the text with setText() or insert(). 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.Ī related class is QTextEdit which allows multi-line, rich text editing.
The text can be arbitrarily constrained using a validator() or an inputMask(), or both. The length of the text can be constrained to maxLength(). If you are new to programming Python PyQt, I highly recommend this book.Def inputMethodQuery (property, argument)ĭef setTextMargins (left, top, right, bottom)Ī 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 (see setDragEnabled() ).īy changing the echoMode() of a line edit, it can also be used as a “write-only” field, for inputs such as passwords.

tGeometry(self.left, self.top, self.width, self.height) The example below creates a window with a textbox.įrom PyQt5.QtWidgets import QMainWindow, QApplication, QWidget, QPushButton, QAction, QLineEdit, QMessageBox The position can be set using the move(x,y) method or using a grid layout.Ĭreation of the textbox is fairly straightforward: We can set the size of the textbox using the resize(width,height) method. The widget is called QLineEdit and has the methods setText() to set the textbox value and text() to get the value.
