Qt - Symbian Mobile - 软键菜单无法正确显示
我创建并显示一个 QWebView，底部带有软键选项。当我单击“选项”时，会出现一个菜单，但它很小，黑色，位于左上角（它应该看起来像标准的蓝色软键，并且位于它们的正上方）。我遵循了这个示例。
//create webview
webView = new QWebView;
webView->setUrl(QString(":html/internal.html"));
//create menu
QAction *option1 = new QAction(tr("Back"), webView);
option1->setSoftKeyRole(QAction::PositiveSoftKey);
connect(option1, SIGNAL(triggered()), this, SLOT(deleteView()));
//create right softkey action to launch the "options" menu
QAction *option2 = new QAction(tr("Options"), webView);
option2->setSoftKeyRole(QAction::NegativeSoftKey);
connect(option2, SIGNAL(triggered(), this, SLOT(showMenu()));
QMenu *menuOptions = new QMenu(webView);
menuOptions->addAction(tr("Sub Menu 1"), this, SLOT(aboutView()));
menuOptions->addAction(tr("Sub Menu 2"), this, SLOT(aboutView()));
option2->setMenu(menuOptions);
//add softkey menus
QList < QAction* > softKeys;
softKeys.append(option1);
softKeys.append(option2);
webView->addActions(softKeys);
webView->show();
I create and show a QWebView with soft key options at the bottom. When I click "Options", a menu shows up, but it's tiny, black, and in the upper left hand corner (it should look like the standard blue soft keys and be directly above them). I followed this example.
//create webview
webView = new QWebView;
webView->setUrl(QString(":html/internal.html"));
//create menu
QAction *option1 = new QAction(tr("Back"), webView);
option1->setSoftKeyRole(QAction::PositiveSoftKey);
connect(option1, SIGNAL(triggered()), this, SLOT(deleteView()));
//create right softkey action to launch the "options" menu
QAction *option2 = new QAction(tr("Options"), webView);
option2->setSoftKeyRole(QAction::NegativeSoftKey);
connect(option2, SIGNAL(triggered(), this, SLOT(showMenu()));
QMenu *menuOptions = new QMenu(webView);
menuOptions->addAction(tr("Sub Menu 1"), this, SLOT(aboutView()));
menuOptions->addAction(tr("Sub Menu 2"), this, SLOT(aboutView()));
option2->setMenu(menuOptions);
//add softkey menus
QList < QAction* > softKeys;
softKeys.append(option1);
softKeys.append(option2);
webView->addActions(softKeys);
webView->show();

此示例在模拟器和手机上都能很好地工作。从 Qt 4.6.x 开始，它包含在 QTDIR/examples/widgets 文件夹中
This example works well on simulator and also in phone. It is included in the QTDIR/examples/widgets folder since Qt 4.6.x
