104 \class QToolButton-
105 \brief The QToolButton class provides a quick-access button to-
106 commands or options, usually used inside a QToolBar.-
107-
108 \ingroup basicwidgets-
109 \inmodule QtWidgets-
110-
111 A tool button is a special button that provides quick-access to-
112 specific commands or options. As opposed to a normal command-
113 button, a tool button usually doesn't show a text label, but shows-
114 an icon instead.-
115-
116 Tool buttons are normally created when new QAction instances are-
117 created with QToolBar::addAction() or existing actions are added-
118 to a toolbar with QToolBar::addAction(). It is also possible to-
119 construct tool buttons in the same way as any other widget, and-
120 arrange them alongside other widgets in layouts.-
121-
122 One classic use of a tool button is to select tools; for example,-
123 the "pen" tool in a drawing program. This would be implemented-
124 by using a QToolButton as a toggle button (see setCheckable()).-
125-
126 QToolButton supports auto-raising. In auto-raise mode, the button-
127 draws a 3D frame only when the mouse points at it. The feature is-
128 automatically turned on when a button is used inside a QToolBar.-
129 Change it with setAutoRaise().-
130-
131 A tool button's icon is set as QIcon. This makes it possible to-
132 specify different pixmaps for the disabled and active state. The-
133 disabled pixmap is used when the button's functionality is not-
134 available. The active pixmap is displayed when the button is-
135 auto-raised because the mouse pointer is hovering over it.-
136-
137 The button's look and dimension is adjustable with-
138 setToolButtonStyle() and setIconSize(). When used inside a-
139 QToolBar in a QMainWindow, the button automatically adjusts to-
140 QMainWindow's settings (see QMainWindow::setToolButtonStyle() and-
141 QMainWindow::setIconSize()). Instead of an icon, a tool button can-
142 also display an arrow symbol, specified with-
143 \l{QToolButton::arrowType} {arrowType}.-
144-
145 A tool button can offer additional choices in a popup menu. The-
146 popup menu can be set using setMenu(). Use setPopupMode() to-
147 configure the different modes available for tool buttons with a-
148 menu set. The default mode is DelayedPopupMode which is sometimes-
149 used with the "Back" button in a web browser. After pressing and-
150 holding the button down for a while, a menu pops up showing a list-
151 of possible pages to jump to. The timeout is style dependent,-
152 see QStyle::SH_ToolButton_PopupDelay.-
