DESCRIPTION
The QToolButton class provides a quick-access button to
specific commands or options, usually used inside a
QToolBar.
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 an icon. Its classic usage is to select
tools, for example the "pen"-tool in a drawing program.
This would be implemented with a QToolButton as 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 QIconSet. 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
user is pointing at it.
The button's look and dimension is adjustable with
setUsesBigPixmap() and setUsesTextLabel(). When used
inside a QToolBar, the button automatically adjusts to
QMainWindow's settings (see
QMainWindow::setUsesTextLabel() and
QMainWindow::setUsesBigPixmaps()).
A tool button can offer additional choices in a popup
menu. The feature is sometimes used with the "Back" button
in a web browsers: After pressing the button down for a
while, a menu pops up showing all possible pages to browse
back. With QToolButton, you can set a popup menu using
setPopup(). The default delay is 600ms, you may adjust it
with setPopupDelay().

QToolButton(3qt)QToolButton(3qt)MEMBER FUNCTION DOCUMENTATIONQToolButton::QToolButton ( QWidget * parent, const char * name =
0 )
Constructs an empty tool button.
QToolButton::QToolButton ( ArrowType type, QWidget * parent,
const char * name = 0 )
Constructs a tool button as arrow button. The ArrowType
type defines the arrow direction. Possible values are
LeftArrow, RightArrow, UpArrow and DownArrow.
An arrow button has auto repeat turned on.
The parent and name arguments are sent to the QWidget
constructor.
QToolButton::QToolButton ( const QIconSet & iconSet, const
QString & textLabel, const QString & grouptext, QObject *
receiver, const char * slot, QToolBar * parent, const char
* name = 0 )
Constructs a tool button that is a child of parent (which
must be a QToolBar) and named name.
The tool button will display iconSet, with text label or
tool tip textLabel and status-bar message grouptext,
connected to slot in object receiver, and returns the
button.
QToolButton::QToolButton ( const QPixmap & pm, const QString &
textLabel, const QString & grouptext, QObject * receiver,
const char * slot, QToolBar * parent, const char * name =
0 )
Constructs a tool button that is a child of parent (which
must be a QToolBar) and named name.
The tool button will display pm, with text label or tool
tip textLabel and status-bar message grouptext, connected
to slot in object receiver, and returns the button.
QToolButton::~QToolButton ()
Destroys the object and frees any allocated resources.
bool QToolButton::autoRaise () const
Returns whether auto-raising is enabled or not.
See also setAutoRaise.
void QToolButton::drawButton ( QPainter * p ) [virtual protected]
Reimplemented for internal reasons; the API is not
affected.
Reimplemented from QButton.

QToolButton(3qt)QToolButton(3qt)void QToolButton::drawButtonLabel ( QPainter * p ) [virtual
protected]
Reimplemented for internal reasons; the API is not
affected.
Reimplemented from QButton.
void QToolButton::enterEvent ( QEvent * e ) [virtual protected]
Reimplemented for internal reasons; the API is not
affected.
Reimplemented from QWidget.
QIconSet QToolButton::iconSet ( bool on = FALSE ) const
Returns a copy of the icon set in use. If no icon set has
been set, iconSet() creates one from the pixmap().
If the button doesn't have a pixmap either, iconSet()'s
return value is meaningless.
If on equals TRUE, the special icon set for the on-state
of the button is returned.
See also setIconSet() and QIconSet.
void QToolButton::leaveEvent ( QEvent * e ) [virtual protected]
Reimplemented for internal reasons; the API is not
affected.
Reimplemented from QWidget.
void QToolButton::moveEvent ( QMoveEvent * ) [virtual protected]
Reimplemented for internal reasons; the API is not
affected.
Reimplemented from QWidget.
QIconSet QToolButton::offIconSet () const
Returns the icon set which is used if the toolbutton is in
off-state.
See also iconSet().
QIconSet QToolButton::onIconSet () const
Returns the icon set which is used if the toolbutton is in
on-state.
See also iconSet().
QPopupMenu* QToolButton::popup () const
Returns the associated popup menu or 0 if no popup menu
has been defined.
See also setPopup().
Trolltech AS 13 June 2001 4
QToolButton(3qt)QToolButton(3qt)int QToolButton::popupDelay () const
Returns the delay between pressing the button and the
appearance of the associated popupmenu in milliseconds.
See also setPopupDelay() and setPopup().
void QToolButton::setAutoRaise ( bool enable )
Enables or disables auto-raising according to enable.
See also autoRaise.
void QToolButton::setIconSet ( const QIconSet & set, bool on =
FALSE ) [virtual]
Sets this tool button to display the icons in set.
(setPixmap() is effectively a wrapper for this function.)
For toggle buttons it is possible to set an extra icon set
with on equals TRUE, which will be used exclusively for
the on-state.
QToolButton makes a copy of set, so you must delete set
yourself.
See also iconSet(), QIconSet, setToggleButton() and
isOn().
void QToolButton::setOffIconSet ( const QIconSet & set )
Sets the icon that is used when the button is in off-
state.
See also setIconSet().
void QToolButton::setOn ( bool enable ) [virtual slot]
Sets this tool button to be on if enable is TRUE, and off
it enable is FALSE.
This function has no effect on non-toggling buttons.
See also isToggleButton() and toggle().
void QToolButton::setOnIconSet ( const QIconSet & set )
Sets the icon that is used when the button is in on-state.
See also setIconSet().
void QToolButton::setPopup ( QPopupMenu * popup )
Associates the popup menu popup with this toolbutton.
The popup will be shown each time the toolbutton has been
pressed down for a certain amount of time. A typical
application example is the "back" button in a web
browser's toolbar. If the user clicks it, the browser
simply browses back to the previous page. If the user
holds the button down for a while, they receive a menu

QToolButton(3qt)QToolButton(3qt)
containing the current history list.
Ownership of the popup menu is not transferred.
See also popup().
void QToolButton::setPopupDelay ( int delay )
Sets the time delay between pressing the button and the
appearance of the associated popupmenu in milliseconds.
Usually this is around 1/2 of a second.
See also popupDelay() and setPopup().
void QToolButton::setTextLabel ( const QString & newLabel )
[slot]
Sets the label of this button to newLabel, and
automatically sets it as tool tip too.
void QToolButton::setTextLabel ( const QString & newLabel, bool
tipToo ) [virtual slot]
Sets the label of this button to newLabel, and
automatically sets it as tool tip too if tipToo is TRUE.
void QToolButton::setToggleButton ( bool enable ) [virtual slot]
Makes the tool button a toggle button if enable is TRUE,
or a normal tool button if enable is FALSE.
Toggle buttons have an on/off state similar to check
boxes. A tool button is initially not a toggle button.
See also setOn(), toggle(), isToggleButton() and
toggled().
void QToolButton::setUsesBigPixmap ( bool enable ) [virtual slot]
Sets this button to use the big pixmaps provided by its
QIconSet if enable is TRUE, and to use the small ones
else.
QToolButton automatically connects this slot to the
relevant signal in the QMainWindow in which it resides.
You're strongly urged to use
QMainWindow::setUsesBigPixmaps() instead.
Warning: If you set some buttons (in a QMainWindow) to
have big and others small pixmaps, QMainWindow may have
trouble getting the geometry correct.
void QToolButton::setUsesTextLabel ( bool enable ) [virtual slot]
Sets this button to draw a text label below the icon if
enable is TRUE, and to not draw it if enable is FALSE.
QToolButton automatically connects this slot to the
relevant signal in the QMainWindow in which is resides.

This function has no effect on non-toggling buttons.
See also isToggleButton() and toggled().

Returns TRUE if this button should be drawn using raised
edges.
See also drawButton().

pixmaps, and FALSE if it does not.
See also setUsesBigPixmap(), setPixmap() and

Returns TRUE if this tool button puts a text label below
the button pixmap, and FALSE if it does not.
See also setUsesTextLabel(), setTextLabel() and
