65 \class QLabel -
66 \brief The QLabel widget provides a text or image display. -
67 -
68 \ingroup basicwidgets -
69 \inmodule QtWidgets -
70 -
71 QLabel is used for displaying text or an image. No user -
72 interaction functionality is provided. The visual appearance of -
73 the label can be configured in various ways, and it can be used -
74 for specifying a focus mnemonic key for another widget. -
75 -
76 A QLabel can contain any of the following content types: -
77 -
78 \table -
79 \header \li Content \li Setting -
80 \row \li Plain text -
81 \li Pass a QString to setText(). -
82 \row \li Rich text -
83 \li Pass a QString that contains rich text to setText(). -
84 \row \li A pixmap -
85 \li Pass a QPixmap to setPixmap(). -
86 \row \li A movie -
87 \li Pass a QMovie to setMovie(). -
88 \row \li A number -
89 \li Pass an \e int or a \e double to setNum(), which converts -
90 the number to plain text. -
91 \row \li Nothing -
92 \li The same as an empty plain text. This is the default. Set -
93 by clear(). -
94 \endtable -
95 -
96 \warning When passing a QString to the constructor or calling setText(), -
97 make sure to sanitize your input, as QLabel tries to guess whether it -
98 displays the text as plain text or as rich text, a subset of HTML 4 -
99 markup. You may want to call -
100 setTextFormat() explicitly, e.g. in case you expect the text to be in -
101 plain format but cannot control the text source (for instance when -
102 displaying data loaded from the Web). -
103 -
104 When the content is changed using any of these functions, any -
105 previous content is cleared. -
106 -
107 By default, labels display \l{alignment}{left-aligned, vertically-centered} -
108 text and images, where any tabs in the text to be displayed are -
109 \l{Qt::TextExpandTabs}{automatically expanded}. However, the look -
110 of a QLabel can be adjusted and fine-tuned in several ways. -
111 -
112 The positioning of the content within the QLabel widget area can -
113 be tuned with setAlignment() and setIndent(). Text content can -
114 also wrap lines along word boundaries with setWordWrap(). For -
115 example, this code sets up a sunken panel with a two-line text in -
116 the bottom right corner (both lines being flush with the right -
117 side of the label): -
118 -
119 \snippet code/src_gui_widgets_qlabel.cpp 0 -
120 -
121 The properties and functions QLabel inherits from QFrame can also -
122 be used to specify the widget frame to be used for any given label. -
123 -
124 A QLabel is often used as a label for an interactive widget. For -
125 this use QLabel provides a useful mechanism for adding an -
126 mnemonic (see QKeySequence) that will set the keyboard focus to -
127 the other widget (called the QLabel's "buddy"). For example: -
128 -
129 \snippet code/src_gui_widgets_qlabel.cpp 1 -
130 -
131 In this example, keyboard focus is transferred to the label's -
132 buddy (the QLineEdit) when the user presses Alt+P. If the buddy -
133 was a button (inheriting from QAbstractButton), triggering the -
134 mnemonic would emulate a button click. -
