As opposed to a normal command + button, a tool button usually doesn't show a text label, but shows + an icon instead. + + Tool buttons are normally created when new QAction instances are + created with QToolBar::addAction() or existing actions are added + to a toolbar with QToolBar::addAction(). It is also possible to + construct tool buttons in the same way as any other widget, and + arrange them alongside other widgets in layouts. + + One classic use of a tool button is to select tools; for example, + the "pen" tool in a drawing program. This would be implemented + by using a QToolButton as a toggle button (see setToggleButton()). + + QToolButton supports auto-raising. In auto-raise mode, the button + draws a 3D frame only when the mouse points at it. The feature is + automatically turned on when a button is used inside a QToolBar. + Change it with setAutoRaise(). + + A tool button's icon is set as QIcon. This makes it possible to + specify different pixmaps for the disabled and active state. The + disabled pixmap is used when the button's functionality is not + available. The active pixmap is displayed when the button is + auto-raised because the mouse pointer is hovering over it. + + The button's look and dimension is adjustable with + setToolButtonStyle() and setIconSize(). When used inside a + QToolBar in a QMainWindow, the button automatically adjusts to + QMainWindow's settings (see QMainWindow::setToolButtonStyle() and + QMainWindow::setIconSize()). Instead of an icon, a tool button can + also display an arrow symbol, specified with + \l{QToolButton::arrowType} {arrowType}. + + A tool button can offer additional choices in a popup menu. The + popup menu can be set using setMenu(). Use setPopupMode() to + configure the different modes available for tool buttons with a + menu set. The default mode is DelayedPopupMode which is sometimes + used with the "Back" button in a web browser. After pressing and + holding the button down for a while, a menu pops up showing a list + of possible pages to jump to. The default delay is 600 ms; you can + adjust it with setPopupDelay(). + + \table 100% + \row \o \inlineimage assistant-toolbar.png Qt Assistant's toolbar with tool buttons + \row \o Qt Assistant's toolbar contains tool buttons that are associated + with actions used in other parts of the main window. + \endtable + + \sa QPushButton, QToolBar, QMainWindow, QAction, + {fowler}{GUI Design Handbook: Push Button} +*/ + +/*! + \fn void QToolButton::triggered(QAction *action) + + This signal is emitted when the given \a action is triggered. + + The action may also be associated with other parts of the user interface, + such as menu items and keyboard shortcuts.
