+ \class TQToolButton qtoolbutton.h
+ \brief The TQToolButton class provides a tquick-access button to
+ commands or options, usually used inside a TQToolBar.
+
+ \ingroup basic
+ \mainclass
+
+ A tool button is a special button that provides tquick-access to
+ specific commands or options. As opposed to a normal command
+ button, a tool button usually doesn't show a text label, but shows
+ an icon instead. Its classic usage is to select tools, for example
+ the "pen" tool in a drawing program. This would be implemented
+ with a TQToolButton as toggle button (see setToggleButton() ).
+
+ TQToolButton 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 TQToolBar.
+ Change it with setAutoRaise().
+
+ A tool button's icon is set as TQIconSet. 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
+ setUsesBigPixmap() and setUsesTextLabel(). When used inside a
+ TQToolBar in a TQMainWindow, the button automatically adjusts to
+ TQMainWindow's settings (see TQMainWindow::setUsesTextLabel() and
+ TQMainWindow::setUsesBigPixmaps()). The pixmap set on a TQToolButton
+ will be set to 22x22 if it is bigger than this size. If
+ usesBigPixmap() is TRUE, then the pixmap will be set to 32x32.
+
+ A tool button can offer additional choices in a popup menu. The
+ feature 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. With
+ TQToolButton you can set a popup menu using setPopup(). The default
+ delay is 600ms; you can adjust it with setPopupDelay().
