TextField

Returns true if the text field contains acceptable text.

If a validator or input mask was set, this property will return true if the current text satisfies the validator or mask as a final string (not as an intermediate string).

The default value is true.

See also validator, inputMask, and accepted.

This property is set to true if the TextField should gain active focus on a mouse press.

The default value is true.

Returns true if the TextField is writable and the content of the clipboard is suitable for pasting into the TextField.

Returns true if the TextField is writable and there are undone operations that can be redone.

Returns true if the TextField is writable and there are previous operations that can be undone.

This property holds the position of the cursor in the TextField.

The rectangle where the text cursor is rendered within the text field.

This QML property was introduced in QtQuick.Controls 1.3.

This property holds the text displayed in the TextField.

If echoMode is set to TextInput::Normal, this holds the same value as the TextField::text property. Otherwise, this property holds the text visible to the user, while the text property holds the actual entered text.

Specifies how the text should be displayed in the TextField.

The possible modes are:

• TextInput.Normal - Displays the text as it is. (Default)
• TextInput.Password - Displays asterisks instead of characters.
• TextInput.NoEcho - Displays nothing.
• TextInput.PasswordEchoOnEdit - Displays characters as they are entered while editing, otherwise displays asterisks.

Gets the effective horizontal alignment of the text within the TextField item's width.

horizontalAlignment contains the default horizontal alignment.

See also horizontalAlignment.

Sets the font of the TextField.

Sets the alignment of the text within the TextField item's width.

By default, the horizontal text alignment follows the natural alignment of the text, for example text that is read from left to right will be aligned to the left.

The possible alignment values are:

• TextInput.AlignLeft
• TextInput.AlignRight
• TextInput.AlignHCenter

When using the attached property, LayoutMirroring::enabled, to mirror application layouts, the horizontal alignment of text will also be mirrored. However, the property horizontalAlignment will remain unchanged. To query the effective horizontal alignment of TextField, use the read-only property effectiveHorizontalAlignment.

This property holds whether the control is being hovered.

Sets an input mask on the TextField, restricting the allowable text inputs. See QLineEdit::inputMask for further details, as the exact same mask strings are used by TextField.

See also acceptableInput and validator.

This property holds whether the TextField has partial text input from an input method.

While it is composing an input method may rely on mouse or key events from the TextField to edit or commit the partial text. This property can be used to determine when to disable events handlers that may interfere with the correct operation of an input method.

This QML property was introduced in QtQuick.Controls 1.3.

Provides hints to the input method about the expected content of the text field and how it should operate.

The value is a bit-wise combination of flags, or Qt.ImhNone if no hints are set.

The default value is Qt.ImhNone.

Flags that alter behavior are:

• Qt.ImhHiddenText - Characters should be hidden, as is typically used when entering passwords. This is automatically set when setting echoMode to TextInput.Password.
• Qt.ImhSensitiveData - Typed text should not be stored by the active input method in any persistent storage like predictive user dictionary.
• Qt.ImhNoAutoUppercase - The input method should not try to automatically switch to upper case when a sentence ends.
• Qt.ImhPreferNumbers - Numbers are preferred (but not required).
• Qt.ImhPreferUppercase - Uppercase letters are preferred (but not required).
• Qt.ImhPreferLowercase - Lowercase letters are preferred (but not required).
• Qt.ImhNoPredictiveText - Do not use predictive text (for example, dictionary lookup) while typing.
• Qt.ImhDate - The text editor functions as a date field.
• Qt.ImhTime - The text editor functions as a time field.
• Qt.ImhMultiLine - The text editor doesn't close software input keyboard when Return or Enter key is pressed (since QtQuick.Controls 1.3).

Flags that restrict input (exclusive flags) are:

• Qt.ImhDigitsOnly - Only digits are allowed.
• Qt.ImhFormattedNumbersOnly - Only number input is allowed. This includes decimal point and minus sign.
• Qt.ImhUppercaseOnly - Only uppercase letter input is allowed.
• Qt.ImhLowercaseOnly - Only lowercase letter input is allowed.
• Qt.ImhDialableCharactersOnly - Only characters suitable for phone dialing are allowed.
• Qt.ImhEmailCharactersOnly - Only characters suitable for email addresses are allowed.
• Qt.ImhUrlCharactersOnly - Only characters suitable for URLs are allowed.

Masks:

• Qt.ImhExclusiveInputMask - This mask yields nonzero if any of the exclusive flags are used.

Returns the total number of characters in the TextField item.

If the TextField has an input mask, the length will include mask characters and may differ from the length of the string returned by the text property.

This property can be faster than querying the length of the text property as it doesn't require any copying or conversion of the TextField's internal string data.

This property holds the maximum permitted length of the text in the TextField.

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

This property contains the edit Menu for working with text selection. Set it to null if no menu is wanted.

This QML property was introduced in QtQuick.Controls 1.3.

This property contains the text that is shown in the text field when the text field is empty.

Sets whether user input can modify the contents of the TextField. Read- only is different from a disabled text field in that the text field will appear to be active and text can still be selected and copied.

If readOnly is set to true, then user input will not affect the text. Any bindings or attempts to set the text property will still work, however.

This property determines if the user can select the text with the mouse.

The default value is true.

This QML property was introduced in QtQuick.Controls 1.3.

Provides the text currently selected in the text input.

It is equivalent to the following snippet, but is faster and easier to use.

myTextField.text.toString().substring(myTextField.selectionStart, myTextField.selectionEnd);

The cursor position after the last character in the current selection.

This property is read-only. To change the selection, use select(start,end), selectAll(), or selectWord().

See also selectionStart, cursorPosition, and selectedText.

The cursor position before the first character in the current selection.

This property is read-only. To change the selection, use select(start,end), selectAll(), or selectWord().

See also selectionEnd, cursorPosition, and selectedText.

The style Component for this control.

See also Qt Quick Controls Styles QML Types.

This property contains the text in the TextField.

This property holds the text color.

Allows you to set a validator on the TextField. When a validator is set, the TextField will only accept input which leaves the text property in an intermediate state. The accepted signal will only be sent if the text is in an acceptable state when enter is pressed.

Currently supported validators are IntValidator, DoubleValidator, and RegExpValidator. An example of using validators is shown below, which allows input of integers between 11 and 31 into the text input:

import QtQuick 2.2
import QtQuick.Controls 1.2

TextField {
    validator: IntValidator {bottom: 11; top: 31;}
    focus: true
}

See also acceptableInput, inputMask, and accepted.

Sets the alignment of the text within the TextField item's height.

The possible alignment values are:

• TextInput.AlignTop
• TextInput.AlignBottom
• TextInput.AlignVCenter (default).

This signal is emitted when the Return or Enter key is pressed. Note that if there is a validator or inputMask set on the text field, the signal will only be emitted if the input is in an acceptable state.

The corresponding handler is onAccepted.

This signal is emitted when the Return or Enter key is pressed or the text field loses focus. Note that if there is a validator or inputMask set on the text field and enter/return is pressed, this signal will only be emitted if the input follows the inputMask and the validator returns an acceptable state.

The corresponding handler is onEditingFinished.

This QML signal was introduced in QtQuick.Controls 1.1.

Copies the currently selected text to the system clipboard.

Moves the currently selected text to the system clipboard.

Removes active text selection.

Removes the section of text that is between the start and end positions from the TextField.

Inserts text into the TextField at position.

Returns true if the natural reading direction of the editor text found between positions start and end is right to left.

Replaces the currently selected text by the contents of the system clipboard.

Performs the last operation if redo is available.

Removes the section of text that is between the start and end positions.

This QML method was introduced in QtQuick.Controls 1.4.

Causes the text from start to end to be selected.

If either start or end is out of range, the selection is not changed.

After calling select, selectionStart will become the lesser and selectionEnd will become the greater (regardless of the order passed to this method).

See also selectionStart and selectionEnd.

Causes all text to be selected.

Causes the word closest to the current cursor position to be selected.

Reverts the last operation if undo is available. undo() deselects any current selection and updates the selection start to the current cursor position.
