.SH DESCRIPTION
The QToolButton class provides a push button whose appearance has been tailored for use in a QToolBar.
.PP
This means that it implements the ridiculous Microsoft auto-raise feature using QIconSet. Apart from that, it's pretty much like a QPushButton. The two classes may at some point be merged.
.PP

.SH MEMBER FUNCTION DOCUMENTATION
.SH "QToolButton::QToolButton ( QWidget * parent, const char * name = 0 )"
Constructs an empty tool button.
.SH "QToolButton::QToolButton ( const QIconSet & iconSet, const QString & textLabel, const QString & grouptext, QObject * receiver, const char * slot, QToolBar * parent, const char * name = 0 )"
Creates a tool button that is a child of \fIparent\fR (which must be a QToolBar) and named \fIname.\fR
.PP
The tool button will display \fIiconSet,\fR with text label or tool tip \fItextLabel\fR and status-bar message \fIgrouptext,\fR connected to \fIslot\fR in object \fIreceiver,\fR and returns the button.
.SH "QToolButton::QToolButton ( const QPixmap & pm, const QString & textLabel, const QString & grouptext, QObject * receiver, const char * slot, QToolBar * parent, const char * name = 0 )"
Creates a tool button that is a child of \fIparent\fR (which must be a QToolBar) and named \fIname.\fR
.PP
The tool button will display \fIpm,\fR with text label or tool tip \fItextLabel\fR and status-bar message \fIgrouptext,\fR connected to \fIslot\fR in object \fIreceiver,\fR and returns the button.
.SH "QToolButton::~QToolButton ()"
Destroys the object and frees any allocated resources.
.SH "void QToolButton::drawButton ( QPainter * p ) \fC[virtual protected]\fR"
Draws the edges and decoration of the button (pretty much nothing) and calls drawButtonLabel().
.PP
See also: drawButtonLabel() and QButton::paintEvent().
.PP
Reimplemented from QButton.
.SH "void QToolButton::drawButtonLabel ( QPainter * p ) \fC[virtual protected]\fR"
Draws the contents of the button (pixmap and optionally text).
.PP
See also: drawButton() and QButton::paintEvent().
.PP
Reimplemented from QButton.
.SH "void QToolButton::enterEvent ( QEvent * e ) \fC[virtual protected]\fR"
Reimplemented to handle the automatic 3D effects in Windows style.
.PP
Reimplemented from QWidget.
.SH "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().
.PP
If the button doesn't have a pixmap either, iconSet()'s return value is meaningless.
.PP
If \fIon\fR equals TRUE, the special icon set for the on-state of the button is returned.
.PP
See also: setIconSet() and QIconSet.
.SH "void QToolButton::leaveEvent ( QEvent * e ) \fC[virtual protected]\fR"
Reimplemented to handle the automatic 3D effects in Windows style.
.PP
Reimplemented from QWidget.
.SH "void QToolButton::setIconSet ( const QIconSet & set, bool on = FALSE ) \fC[virtual]\fR"
Sets this tool button to display the icons in \fIset.\fR (setPixmap() is effectively a wrapper for this function.)
.PP
For toggle buttons it is possible to set an extra icon set with \fIon\fR equals TRUE, which will be used exclusively for the on-state.
.PP
QToolButton makes a copy of \fIset,\fR so you must delete \fIset\fR yourself.
.PP
See also: iconSet(), QIconSet, setToggleButton() and isOn().
.SH "void QToolButton::setOn ( bool enable ) \fC[virtual slot]\fR"
Sets this tool button to be on if \fIenable\fR is TRUE, and off it \fIenable\fR is FALSE.
.PP
This function has no effect on non-toggling buttons.
.PP
See also: isToggleButton() and toggle().
.SH "void QToolButton::setTextLabel ( const QString & newLabel, bool tipToo = TRUE ) \fC[virtual slot]\fR"
Sets the label of this button to \fInewLabel,\fR and automatically sets it as tool tip too if \fItipToo\fR is TRUE.
.SH "void QToolButton::setToggleButton ( bool enable ) \fC[virtual slot]\fR"
Makes the tool button a toggle button if \fIenable\fR is TRUE, or a normal tool button if \fIenable\fR is FALSE.
.PP
Toggle buttons have an on/off state similar to check boxes. A tool button is initially not a toggle button.
.PP
See also: setOn(), toggle(), toggleButton() and toggled().
.SH "void QToolButton::setUsesBigPixmap ( bool enable ) \fC[virtual slot]\fR"
Sets this button to use the big pixmaps provided by its QIconSet if \fIenable\fR is TRUE, and to use the small ones else.
.PP
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.
.PP
\fBWarning:\fR If you set some buttons (in a QMainWindow) to have big and others small pixmaps, QMainWindow may have trouble getting the geometry correct.
.SH "void QToolButton::setUsesTextLabel ( bool enable ) \fC[virtual slot]\fR"
Sets this button to draw a text label below the icon if \fIenable\fR is TRUE, and to not draw it if \fIenable\fR is FALSE.
.PP
QToolButton automatically connects this slot to the relevant signal in the QMainWindow in which is resides.
.SH "QSize QToolButton::sizeHint () const \fC[virtual]\fR"
Returns a size suitable for this tool button. This depends on GUI style, usesBigPixmap(), textLabel() and usesTextLabel().
.PP
Reimplemented from QWidget.
.SH "QSizePolicy QToolButton::sizePolicy () const \fC[virtual]\fR"
Specifies that this widget may grow.
.PP
Reimplemented from QWidget.
.SH "QString QToolButton::textLabel () const"
Returns the text label in use by this tool button, or 0.
.PP
See also: setTextLabel(), usesTextLabel(), setUsesTextLabel() and setText().
.SH "void QToolButton::toggle () \fC[slot]\fR"
Toggles the state of this tool button.
.PP
This function has no effect on non-toggling buttons.
.PP
See also: isToggleButton() and toggle().
.SH "bool QToolButton::uses3D () const \fC[protected]\fR"
Returns TRUE if this button should be drawn using raised edges.
.PP
See also: drawButton().
.SH "bool QToolButton::usesBigPixmap () const"
Returns TRUE if this tool button uses the big (32-pixel) pixmaps, and FALSE if it does not.
.PP
See also: setUsesBigPixmap(), setPixmap() and usesTextLabel.
.SH "bool QToolButton::usesTextLabel () const"
Returns TRUE if this tool button puts a text label below the button pixmap, and FALSE if it does not.
.PP
See also:  setUsesTextLabel(), setTextLabel() and usesBigPixmap().
