class QTabWidget;
class QMenu;

// This class creates a dialog with zero or more tabs. For zero tabs it is
// just a single QWebView inside the dialog. For 1 or more tabs, each tab
// contains a separate QWebView. Each QWebView can have either plain text or
// html text. The class will automatically delete itself when closed.
// The class can either be directly called or subclassed. The dialog is not modal.

// Typical direct usage:
//
//                        Zero tabs
// BtTabHtmlDialog* dlg = new BtTabHtmlDialog("My Title", 0, parent);
// dlg->setHtml(htmlText);
// dlg->show();
//
//     or
//
//                        Two tabs
// BtTabHtmlDialog* dlg = new BtTabHtmlDialog("My Title", 2, parent);
// dlg->selectTab(0);
// dlg->setTabText(nameOfTab0);
// dlg->setHtml(htmlText0);
// dlg->selectTab(1);
// dlg->setTabText(nameOfTab1);
// dlg->setHtml(htmlText1);
// dlg->show();
