.TP
\fCQTabWidget::Bottom\fR - below the pages
.SH "QTabWidget::TabShape"
This enum type defines the shape of the tabs:
.TP
\fCQTabWidget::Rounded\fR - rounded look (normal)
.TP
\fCQTabWidget::Triangular\fR - triangular look (very unusual, included for completeness)
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QTabWidget::QTabWidget ( QWidget * parent = 0, const char * name = 0, WFlags f = 0 )"
Constructs a tabbed widget called \fIname\fR with parent \fIparent\fR, and widget flags \fIf\fR.
.SH "void QTabWidget::addTab ( QWidget * child, const QString & label )\fC [virtual]\fR"
Adds another tab and page to the tab view.
.PP
The new page is \fIchild\fR; the tab's label is \fIlabel\fR. Note the difference between the widget name (which you supply to widget constructors and to setTabEnabled(), for example) and the tab label. The name is internal to the program and invariant, whereas the label is shown on-screen and may vary according to language and other factors.
.PP
If the tab's \fIlabel\fR contains an ampersand, the letter following the ampersand is used as an accelerator for the tab, e.g. if the label is "Bro&wse" then Alt+W becomes an accelerator which will move the focus to this tab.
.PP
If you call addTab() after show() the screen will flicker and the user may be confused.
.PP
See also insertTab().
.PP
Examples:
.)l addressbook/centralwidget.cpp and themes/themes.cpp.
.SH "void QTabWidget::addTab ( QWidget * child, const QIconSet & iconset, const QString & label )\fC [virtual]\fR"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Adds another tab and page to the tab view.
.PP
This function is the same as addTab(), but with an additional \fIiconset\fR.
.SH "void QTabWidget::addTab ( QWidget * child, QTab * tab )\fC [virtual]\fR"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
This is a low-level function for adding tabs. It is useful if you are using setTabBar() to set a QTabBar subclass with an overridden QTabBar::paint() function for a subclass of QTab. The \fIchild\fR is the new page and \fItab\fR is the tab to put the \fIchild\fR on.
.SH "void QTabWidget::changeTab ( QWidget * w, const QString & label )"
Defines a new \fIlabel\fR for page \fIw\fR's tab.
.SH "void QTabWidget::changeTab ( QWidget * w, const QIconSet & iconset, const QString & label )"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Defines a new \fIiconset\fR and a new \fIlabel\fR for page \fIw\fR's tab.
.SH "int QTabWidget::count () const"
Returns the number of tabs in the tab bar. See the "count" property for details.
.SH "void QTabWidget::currentChanged ( QWidget * )\fC [signal]\fR"
This signal is emitted whenever the current page changes. The parameter is the new current page.
.PP
See also currentPage(), showPage(), and tabLabel().
.SH "QWidget * QTabWidget::currentPage () const"
Returns a pointer to the page currently being displayed by the tab dialog. The tab dialog does its best to make sure that this value is never 0 (but if you try hard enough, it can be).
.SH "int QTabWidget::currentPageIndex () const"
Returns the index position of the current tab page. See the "currentPage" property for details.
.SH "int QTabWidget::indexOf ( QWidget * w ) const"
Returns the index position of page \fIw\fR, or -1 if the widget cannot be found.
.SH "void QTabWidget::insertTab ( QWidget * child, const QString & label, int index = -1 )\fC [virtual]\fR"
Inserts another tab and page to the tab view.
.PP
The new page is \fIchild\fR; the tab's label is \fIlabel\fR. Note the difference between the widget name (which you supply to widget constructors and to setTabEnabled(), for example) and the tab label. The name is internal to the program and invariant, whereas the label is shown on-screen and may vary according to language and other factors.
.PP
If the tab's \fIlabel\fR contains an ampersand, the letter following the ampersand is used as an accelerator for the tab, e.g. if the label is "Bro&wse" then Alt+W becomes an accelerator which will move the focus to this tab.
.PP
If \fIindex\fR is not specified, the tab is simply appended. Otherwise it is inserted at the specified position.
.PP
If you call insertTab() after show(), the screen will flicker and the user may be confused.
.PP
See also addTab().
.SH "void QTabWidget::insertTab ( QWidget * child, const QIconSet & iconset, const QString & label, int index = -1 )\fC [virtual]\fR"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Inserts another tab and page to the tab view.
.PP
This function is the same as insertTab(), but with an additional \fIiconset\fR.
.SH "void QTabWidget::insertTab ( QWidget * child, QTab * tab, int index = -1 )\fC [virtual]\fR"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
This is a lower-level method for inserting tabs, similar to the other insertTab() method. It is useful if you are using setTabBar() to set a QTabBar subclass with an overridden QTabBar::paint() function for a subclass of QTab. The \fIchild\fR is the new page, \fItab\fR is the tab to put the \fIchild\fR on and \fIindex\fR is the position in the tab bar that this page should occupy.
.SH "bool QTabWidget::isTabEnabled ( QWidget * w ) const"
Returns TRUE if the page \fIw\fR is enabled; otherwise returns FALSE.
.PP
See also setTabEnabled() and QWidget::enabled.
.SH "QString QTabWidget::label ( int index ) const"
Returns the label of the tab at index position \fIindex\fR or QString::null if the \fIindex\fR is out of range.
.SH "int QTabWidget::margin () const"
Returns the margin in this tab widget. See the "margin" property for details.
.SH "QWidget * QTabWidget::page ( int index ) const"
Returns the tab page at index position \fIindex\fR or 0 if the \fIindex\fR is out of range.
.SH "void QTabWidget::removePage ( QWidget * w )\fC [virtual slot]\fR"
Removes page \fIw\fR from this stack of widgets. Does not delete \fIw\fR.
.PP
See also showPage() and QWidgetStack::removeWidget().
.SH "void QTabWidget::removeTabToolTip ( QWidget * w )"
Removes the tab tool tip for page \fIw\fR. If the page does not have a tip, nothing happens.
.PP
See also setTabToolTip() and tabToolTip().
.SH "void QTabWidget::setCurrentPage ( int )\fC [slot]\fR"
Sets the index position of the current tab page. See the "currentPage" property for details.
.SH "void QTabWidget::setMargin ( int )"
Sets the margin in this tab widget. See the "margin" property for details.
.SH "void QTabWidget::setTabBar ( QTabBar * tb )\fC [protected]\fR"
Replaces the dialog's QTabBar heading with the tab bar \fItb\fR. Note that this must be called \fIbefore\fR any tabs have been added, or the behavior is undefined.
.PP
See also tabBar().
.SH "void QTabWidget::setTabEnabled ( QWidget * w, bool enable )"
If \fIenable\fR is TRUE, page \fIw\fR is enabled; otherwise page \fIw\fR is disabled. The page's tab is redrawn appropriately.
.PP
QTabWidget uses QWidget::setEnabled() internally, rather than keeping a separate flag.
.PP
Note that even a disabled tab/page may be visible. If the page is visible already, QTabWidget will not hide it; if all the pages are disabled, QTabWidget will show one of them.
.PP
See also isTabEnabled() and QWidget::enabled.
.SH "void QTabWidget::setTabIconSet ( QWidget * w, const QIconSet & iconset )"
Sets the iconset for page \fIw\fR to \fIiconset\fR.
.SH "void QTabWidget::setTabLabel ( QWidget * w, const QString & l )"
Sets the tab label for page \fIw\fR to \fIl\fR
.SH "void QTabWidget::setTabPosition ( TabPosition )"
Sets the position of the tabs in this tab widget. See the "tabPosition" property for details.
.SH "void QTabWidget::setTabShape ( TabShape s )"
Sets the shape of the tabs in this tab widget to \fIs\fR. See the "tabShape" property for details.
.SH "void QTabWidget::setTabToolTip ( QWidget * w, const QString & tip )"
Sets the tab tool tip for page \fIw\fR to \fItip\fR.
.PP
See also removeTabToolTip() and tabToolTip().
.SH "void QTabWidget::showPage ( QWidget * w )\fC [virtual slot]\fR"
Ensures that page \fIw\fR is shown. This is useful mainly for accelerators.
.PP

.PP
See also QTabBar::currentTab.
.SH "QTabBar * QTabWidget::tabBar () const\fC [protected]\fR"
Returns the current QTabBar.
.PP
See also setTabBar().
.SH "QIconSet QTabWidget::tabIconSet ( QWidget * w ) const"
