\class TQToolButton ntqtoolbutton.h
\brief The TQToolButton class provides a quick-access button to
commands or options, usually used inside a TQToolBar.
\ingroup basic
\mainclass
A tool button is a special button that provides quick-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().
