70 \class QToolTip -
71 -
72 \brief The QToolTip class provides tool tips (balloon help) for any -
73 widget. -
74 -
75 \ingroup helpsystem -
76 \inmodule QtWidgets -
77 -
78 The tip is a short piece of text reminding the user of the -
79 widget's function. It is drawn immediately below the given -
80 position in a distinctive black-on-yellow color combination. The -
81 tip can be any \l{QTextEdit}{rich text} formatted string. -
82 -
83 Rich text displayed in a tool tip is implicitly word-wrapped unless -
84 specified differently with \c{<p style='white-space:pre'>}. -
85 -
86 The simplest and most common way to set a widget's tool tip is by -
87 calling its QWidget::setToolTip() function. -
88 -
89 It is also possible to show different tool tips for different -
90 regions of a widget, by using a QHelpEvent of type -
91 QEvent::ToolTip. Intercept the help event in your widget's \l -
92 {QWidget::}{event()} function and call QToolTip::showText() with -
93 the text you want to display. The \l{widgets/tooltips}{Tooltips} -
94 example illustrates this technique. -
95 -
96 If you are calling QToolTip::hideText(), or QToolTip::showText() -
97 with an empty string, as a result of a \l{QEvent::}{ToolTip}-event you -
98 should also call \l{QEvent::}{ignore()} on the event, to signal -
99 that you don't want to start any tooltip specific modes. -
100 -
101 Note that, if you want to show tooltips in an item view, the -
102 model/view architecture provides functionality to set an item's -
103 tool tip; e.g., the QTableWidgetItem::setToolTip() function. -
104 However, if you want to provide custom tool tips in an item view, -
105 you must intercept the help event in the -
106 QAbstractItemView::viewportEvent() function and handle it yourself. -
107 -
108 The default tool tip color and font can be customized with -
109 setPalette() and setFont(). When a tooltip is currently on -
110 display, isVisible() returns true and text() the currently visible -
111 text. -
112 -
113 \note Tool tips use the inactive color group of QPalette, because tool -
114 tips are not active windows. -
