QLineEdit *phoneEdit = new QLineEdit( this) QLabel *nameLabel = new QLabel( "&Name:", this) QLineEdit *nameEdit = new QLineEdit( this) In a dialog, you might create two data entry widgets and a label for each, and set up the geometry layout so each label is just to the left of its data entry widget (its "buddy"), for example: See the QKeySequence::mnemonic() documentation for details (to display an actual ampersand, use '&'). This character is set as the shortcut key. The buddy mechanism is only available for QLabels that contain text in which one character is prefixed with an ampersand, '&'. When the user presses the shortcut key indicated by this label, the keyboard focus is transferred to the label's buddy widget. Note: The textInteractionFlags set on the label need to include either TextSelectableByMouse or TextSelectableByKeyboard. SelectionStart() returns the index of the first selected character in the label or -1 if no text is selected. Returns the resource provider for rich text of this label.

For example, this code sets up a sunken panel with a two-line text in the bottom right corner (both lines being flush with the right side of the label): Text content can also wrap lines along word boundaries with setWordWrap(). The positioning of the content within the QLabel widget area can be tuned with setAlignment() and setIndent(). However, the look of a QLabel can be adjusted and fine-tuned in several ways. When the content is changed using any of these functions, any previous content is cleared.īy default, labels display left-aligned, vertically-centered text and images, where any tabs in the text to be displayed are automatically expanded. in case you expect the text to be in plain format but cannot control the text source (for instance when displaying data loaded from the Web). You may want to call setTextFormat() explicitly, e.g. Warning: When passing a QString to the constructor or calling setText(), make sure to sanitize your input, as QLabel tries to guess whether it displays the text as plain text or as rich text, a subset of HTML 4 markup.
