.SH "void QTabDialog::applyButtonPressed ()\fC [signal]\fR"
This signal is emitted when either the Apply or OK button is clicked.
.PP
It should be connected to a slot (or several slots) that change the application's state according to the state of the dialog.
.PP
See also cancelButtonPressed(), defaultButtonPressed(), and setApplyButton().
.SH "void QTabDialog::cancelButtonPressed ()\fC [signal]\fR"
This signal is emitted when the Cancel button is clicked. It is automatically connected to QDialog::reject(), which will hide the dialog.
.PP
The Cancel button should not change the application's state at all, so you should generally not need to connect it to any slot.
.PP
See also applyButtonPressed(), defaultButtonPressed(), and setCancelButton().
.SH "void QTabDialog::changeTab ( QWidget * w, const QIconSet & iconset, const QString & label )"
Changes tab page \fIw\fR's iconset to \fIiconset\fR and label to \fIlabel\fR.
.SH "void QTabDialog::changeTab ( QWidget * w, const QString & label )"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Defines a new \fIlabel\fR for the tab of page \fIw\fR
.SH "void QTabDialog::currentChanged ( QWidget * )\fC [signal]\fR"
This signal is emitted whenever the current page changes.
.PP
See also currentPage(), showPage(), and tabLabel().
.SH "QWidget * QTabDialog::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 "void QTabDialog::defaultButtonPressed ()\fC [signal]\fR"
This signal is emitted when the Defaults button is pressed. It should reset the dialog (but not the application) to the "factory defaults".
.PP
The application's state should not be changed until the user clicks Apply or OK.
.PP
See also applyButtonPressed(), cancelButtonPressed(), and setDefaultButton().
.SH "bool QTabDialog::hasApplyButton () const"
Returns TRUE if the tab dialog has an Apply button; otherwise returns FALSE.
.PP
See also setApplyButton(), applyButtonPressed(), hasCancelButton(), and hasDefaultButton().
.SH "bool QTabDialog::hasCancelButton () const"
Returns TRUE if the tab dialog has a Cancel button; otherwise returns FALSE.
.PP
See also setCancelButton(), cancelButtonPressed(), hasApplyButton(), and hasDefaultButton().
.SH "bool QTabDialog::hasDefaultButton () const"
Returns TRUE if the tab dialog has a Defaults button; otherwise returns FALSE.
.PP
See also setDefaultButton(), defaultButtonPressed(), hasApplyButton(), and hasCancelButton().
.SH "bool QTabDialog::hasHelpButton () const"
Returns TRUE if the tab dialog has a Help button; otherwise returns FALSE.
.PP
See also setHelpButton(), helpButtonPressed(), hasApplyButton(), and hasCancelButton().
.SH "bool QTabDialog::hasOkButton () const"
Returns TRUE if the tab dialog has an OK button; otherwise returns FALSE.
.PP
See also setOkButton(), hasApplyButton(), hasCancelButton(), and hasDefaultButton().
.SH "void QTabDialog::helpButtonPressed ()\fC [signal]\fR"
This signal is emitted when the Help button is pressed. It could be used to present information about how to use the dialog.
.PP
See also applyButtonPressed(), cancelButtonPressed(), and setHelpButton().
.SH "void QTabDialog::insertTab ( QWidget * child, const QString & label, int index = -1 )"
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 added. 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 QTabDialog::insertTab ( QWidget * child, const QIconSet & iconset, const QString & label, int index = -1 )"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
This version of the function shows the \fIiconset\fR as well as the \fIlabel\fR on the tab of \fIchild\fR.
.SH "void QTabDialog::insertTab ( QWidget * child, QTab * tab, int index = -1 )"
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.
.PP
The \fIchild\fR is the widget to be placed on the new tab page. The \fItab\fR is the tab to display on the tab page -- normally this shows a label or an icon that identifies the tab page. The \fIindex\fR is the position where this tab page should be inserted.
.SH "bool QTabDialog::isTabEnabled ( QWidget * w ) const"
Returns TRUE if the page \fIw\fR is enabled; otherwise returns FALSE.
.PP
See also setTabEnabled() and QWidget::enabled.
.SH "bool QTabDialog::isTabEnabled ( const char * name ) const"
\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
.PP
Returns TRUE if the page with object name \fIname\fR is enabled and FALSE if it is disabled.
.PP
If \fIname\fR is 0 or not the name of any of the pages, isTabEnabled() returns FALSE.
.PP
See also setTabEnabled() and QWidget::enabled.
.SH "void QTabDialog::removePage ( QWidget * w )"
Removes page \fIw\fR from this stack of widgets. Does not delete \fIw\fR.
.PP
See also showPage(), QTabWidget::removePage(), and QWidgetStack::removeWidget().
.SH "void QTabDialog::selected ( const QString & )\fC [signal]\fR"
\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
.PP
This signal is emitted whenever a tab is selected (raised), including during the first show().
.PP
See also raise().
.SH "void QTabDialog::setApplyButton ( const QString & text )"
Adds an Apply button to the dialog. The button's text is set to \fItext\fR.
.PP
The Apply button should apply the current settings in the dialog box to the application while keeping the dialog visible.
.PP
When Apply is clicked, the applyButtonPressed() signal is emitted.
.PP
If \fItext\fR is a null string, no button is shown.
.PP
See also setCancelButton(), setDefaultButton(), and applyButtonPressed().
.SH "void QTabDialog::setApplyButton ()"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Adds an Apply button to the dialog. The button's text is set to a localizable "Apply".
.SH "void QTabDialog::setCancelButton ( const QString & text )"
Adds a Cancel button to the dialog. The button's text is set to \fItext\fR.
.PP
The cancel button should always return the application to the state it was in before the tab view popped up, or if the user has clicked Apply, back to the state immediately after the last Apply.
.PP
When Cancel is clicked, the cancelButtonPressed() signal is emitted. The dialog is closed at the same time.
.PP
If \fItext\fR is a null string, no button is shown.
.PP
See also setApplyButton(), setDefaultButton(), and cancelButtonPressed().
.SH "void QTabDialog::setCancelButton ()"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Adds a Cancel button to the dialog. The button's text is set to a localizable "Cancel".
.SH "void QTabDialog::setDefaultButton ( const QString & text )"
Adds a Defaults button to the dialog. The button's text is set to \fItext\fR.
.PP
The Defaults button should set the dialog (but not the application) back to the application defaults.
.PP
When Defaults is clicked, the defaultButtonPressed() signal is emitted.
.PP
If \fItext\fR is a null string, no button is shown.
.PP
See also setApplyButton(), setCancelButton(), and defaultButtonPressed().
.SH "void QTabDialog::setDefaultButton ()"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Adds a Defaults button to the dialog. The button's text is set to a localizable "Defaults".
.SH "void QTabDialog::setFont ( const QFont & font )\fC [virtual]\fR"
Sets the font for the tabs to \fIfont\fR.
.PP
If the widget is visible, the display is updated with the new font immediately. There may be some geometry changes, depending on the size of the old and new fonts.
.PP
Reimplemented from QWidget.
.SH "void QTabDialog::setHelpButton ( const QString & text )"
Adds a Help button to the dialog. The button's text is set to \fItext\fR.
.PP
When Help is clicked, the helpButtonPressed() signal is emitted.
.PP
If \fItext\fR is a null string, no button is shown.
.PP
See also setApplyButton(), setCancelButton(), and helpButtonPressed().
.SH "void QTabDialog::setHelpButton ()"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Adds a Help button to the dialog. The button's text is set to a localizable "Help".
.SH "void QTabDialog::setOkButton ( const QString & text )"
Adds an OK button to the dialog and sets the button's text to \fItext\fR.
.PP
When the OK button is clicked, the applyButtonPressed() signal is emitted, and the current settings in the dialog box should be applied to the application. The dialog then closes.
.PP
If \fItext\fR is a null string, no button is shown.
.PP
See also setCancelButton(), setDefaultButton(), and applyButtonPressed().
.SH "void QTabDialog::setOkButton ()"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Adds an OK button to the dialog. The button's text is set to a localizable "OK".
.SH "void QTabDialog::setTabBar ( QTabBar * tb )\fC [protected]\fR"
Replaces the QTabBar heading the dialog by the given 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 QTabDialog::setTabEnabled ( QWidget * w, bool enable )"
If \fIenable\fR is TRUE the page \fIw\fR is enabled; otherwise \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 and tab page may be visible. If the page is already visible 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 QTabDialog::setTabEnabled ( const char * name, bool enable )"
\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
.PP
Finds the page with object name \fIname\fR, enables/disables it according to the value of \fIenable\fR and redraws the page's tab appropriately.
.PP
QTabDialog 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 already visible QTabDialog will not hide it; if all the pages are disabled QTabDialog will show one of them.
.PP
The object name is used (rather than the tab label) because the tab text may not be invariant in multi-language applications.
.PP
See also isTabEnabled() and QWidget::enabled.
.SH "void QTabDialog::showPage ( QWidget * w )"
Ensures that widget \fIw\fR is shown. This is mainly useful for accelerators.
.PP
\fBWarning:\fR If used carelessly, this function can easily surprise or confuse the user.
.PP
See also QTabBar::currentTab.
.SH "QTabBar * QTabDialog::tabBar () const\fC [protected]\fR"
Returns the currently set QTabBar.
.PP
See also setTabBar().
.SH "QString QTabDialog::tabLabel ( QWidget * w )"
Returns the text in the tab for page \fIw\fR.
