In addition, Q3TabDialog provides an OK button and the + following optional buttons: Apply, Cancel, Defaults and Help. + + The normal way to use Q3TabDialog is to do the following in the + constructor: + \list 1 + \i Create a Q3TabDialog. + \i Create a QWidget for each of the pages in the tab dialog, insert + children into it, set up geometry management for it, and use + addTab() (or insertTab()) to set up a tab and keyboard accelerator + for it. + \i Set up the buttons for the tab dialog using setOkButton(), + setApplyButton(), setDefaultsButton(), setCancelButton() and + setHelpButton(). + \i Connect to the signals and slots. + \endlist + + If you don't call addTab() the page you have created will not be + visible. Don't confuse the object name you supply to the + QWidget constructor and the tab label you supply to addTab(); + addTab() takes user-visible name that appears on the widget's tab + and may identify an accelerator, whereas the widget name is used + primarily for debugging. + + Almost all applications have to connect the applyButtonPressed() + signal to something. applyButtonPressed() is emitted when either OK + or Apply is clicked, and your slot must copy the dialog's state into + the application. + + There are also several other signals which may be useful: + \list + \i cancelButtonPressed() is emitted when the user clicks Cancel. + \i defaultButtonPressed() is emitted when the user clicks Defaults; + the slot it is connected to should reset the state of the dialog to + the application defaults. + \i helpButtonPressed() is emitted when the user clicks Help. + \i aboutToShow() is emitted at the start of show(); if there is any + chance that the state of the application may change between the + creation of the tab dialog and the time show() is called, you must + connect this signal to a slot that resets the state of the dialog. + \i currentChanged() is emitted when the user selects a page. + \endlist + + Each tab is either enabled or disabled at any given time (see + setTabEnabled()). If a tab is enabled the tab text is drawn in + black and the user can select that tab. If it is disabled the tab + is drawn in a different way and the user cannot select that tab. + Note that even if a tab is disabled, the page can still be visible; + for example, if all of the tabs happen to be disabled. + + You can change a tab's label and iconset using changeTab(). A tab + page can be removed with removePage() and shown with showPage(). The + current page is given by currentPage(). + + Q3TabDialog does not support tabs on the sides or bottom, nor can + you set or retrieve the visible page. If you need more functionality + than Q3TabDialog provides, consider creating a QDialog and using a + QTabBar with QTabWidgets. + + Most of the functionality in Q3TabDialog is provided by a QTabWidget. +*/ + +/*! + \fn void Q3TabDialog::selected(const QString &name) + + This signal is emitted whenever a tab is selected (raised), + including during the first show(). \a name is the name of the + selected tab. + + \sa raise() +*/ + +/*! \fn void Q3TabDialog::currentChanged(QWidget *widget) + + This signal is emitted whenever the current page changes. \a widget + is the new current page. + + \sa currentPage(), showPage(), tabLabel() +*/ + +class Q3TabDialogPrivate +{ +public: + Q3TabDialogPrivate(); + + QTabWidget* tw; + + QPushButton * ok; + QPushButton * cb; + QPushButton * db; + QPushButton * hb; + QPushButton * ab; + + QBoxLayout * tll; +}; + +Q3TabDialogPrivate::Q3TabDialogPrivate() + : tw(0), + ok(0), cb(0), db(0), hb(0), ab(0), + tll(0) +{ } + +/*! + Constructs a Q3TabDialog with only an OK button. + The \a parent, \a name, \a modal and widget flag, \a f, arguments + are passed on to the QDialog constructor. +*/ + +Q3TabDialog::Q3TabDialog(QWidget *parent, const char *name, bool modal, Qt::WindowFlags f) + : QDialog(parent, name, modal, f) +{ + d = new Q3TabDialogPrivate; + Q_CHECK_PTR(d); + + d->tw = new QTabWidget(this, "tab widget"); + connect (d->tw, SIGNAL (selected(QString)), this, SIGNAL(selected(QString))); + connect (d->tw, SIGNAL (currentChanged(QWidget*)), this, SIGNAL(currentChanged(QWidget*))); + + d->ok = new QPushButton(this, "ok"); + Q_CHECK_PTR(d->ok); + d->ok->setText(tr("OK")); + d->ok->setDefault(true); + connect(d->ok, SIGNAL(clicked()), + this, SIGNAL(applyButtonPressed())); + connect(d->ok, SIGNAL(clicked()), + this, SLOT(accept())); +} + + +/*! + Destroys the tab dialog. +*/ + +Q3TabDialog::~Q3TabDialog() +{ + delete d; +} + + +/*! + Sets the font for the tabs to \a font. + + If the widget is visible, the display is updated with the new font + immediately.
