TextField QML Type

  • Import Statement: import QtQuick.Controls 1.4

  • Since: Qt 5.1

  • Inherits: FocusScope

  • Group: TextField is part of Buttons and Controls

Detailed Description

Image non disponible

TextField is used to accept a line of text input. Input constraints can be placed on a TextField item (for example, through a validator or inputMask). Setting echoMode to an appropriate value enables TextField to be used for a password input field.

 
Sélectionnez
TextField {
    placeholderText: qsTr("Enter name")
}

You can create a custom appearance for a TextField by assigning a TextFieldStyle.

Property Documentation

 

[read-only] acceptableInput : bool

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

activeFocusOnPress : bool

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

The default value is true.

[read-only] canPaste : bool

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

[read-only] canRedo : bool

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

[read-only] canUndo : bool

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

cursorPosition : int

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

[read-only, since QtQuick.Controls 1.3] cursorRectangle : rect

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

This property was introduced in QtQuick.Controls 1.3.

[read-only] displayText : string

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.

echoMode : enumeration

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.

[read-only] effectiveHorizontalAlignment : enumeration

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

horizontalAlignment contains the default horizontal alignment.

See Also

font : font

Sets the font of the TextField.

horizontalAlignment : enumeration

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:

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.

[read-only] hovered : bool

This property holds whether the control is being hovered.

inputMask : string

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.

[read-only, since QtQuick.Controls 1.3] inputMethodComposing : bool

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 property was introduced in QtQuick.Controls 1.3.

inputMethodHints : enumeration

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.

[read-only] length : int

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.

maximumLength : int

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.

[since QtQuick.Controls 1.3] menu : Component

This property was introduced in QtQuick.Controls 1.3.

placeholderText : string

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

readOnly : bool

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.

[since QtQuick.Controls 1.3] selectByMouse : bool

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

The default value is true.

This property was introduced in QtQuick.Controls 1.3.

[read-only] selectedText : string
