qt5.4

I am trying to port an application that uses QtWebKit to render web content over to one that uses QtWebEngine. I am limited what I can change architecturally so I have to stick with the current approach of rendering the page, capturing to a memory buffer and then moving that across to a different process where the buffer is used as a texture in OpenGL. I've tried porting the code over (broadly speaking) by replacing WebKit with WebEngine, but the APIs are different. Can anyone tell me if this is possible? If so, please point me in the right direction to illustrates how to hook everything up.

When I run the Qt Creator dbus examples, they couldn't run, is there any settings or stuff for working QtDbus module or any prerequistics? for example in chat project: if (!QDBusConnection::sessionBus().isConnected()) { qWarning("Cannot connect to the D-Bus session bus.\n" "Please check your system settings and try again.\n"); return 1; } returns 1 and program terminated. Finally I found the solution: For QtDbus module get working, The 3rd party Dbus module must be installed in Windows: Dbus Windows Installer Download After downloading and installing Dbus, it gets working without any

From C++ (Qt): int main(int argc, char *argv[]) { QApplication app(argc, argv); /* * I have omitted the code about connection with the database and all for ease of * viewing the code. */ // My own function for filling in the data in the `QSqlQueryModel` QSqlQueryModel* model = new QSqlQueryModel; QString binid = "B1"; QString query = "SELECT t1.BinId, t1.PartitionId, t2.UnitId, t2.ItemCount FROM Bin_Partitions AS t1 " "INNER JOIN Partition_Units AS t2 ON t1.PartitionId = t2.PartitionId " "WHERE t1.BinId ='" + binid + "'"; model->setQuery(query); /* * I can see that the query runs successfully

We are trying to port some application from Qt 4 to Qt 5.4. The Qt 5.4 has a new web engine. We used to make the background of QWebView and QWebPage to be transparent: view = new QWebView(this); QPalette palette = view->palette(); palette.setBrush(QPalette::Base, Qt::transparent); view->page()->setPalette(palette); view->setAttribute(Qt::WA_OpaquePaintEvent, false); But this code doesn't work for QWebEngineView and QWebEnginePage . The point is that QWebEnginePage doesn't have such an API like setPalette . Can anyone find a way to solve this? As mentioned in https://bugreports.qt.io/browse

I have a global singleton "Settings" which holds application settings. When I try to run the following code I get a QML CheckBox: Binding loop detected for property "checked" : CheckBox { checked: Settings.someSetting onCheckedChanged: { Settings.someSetting = checked; } } It is obvious why this error occurs, but how can I correctly implement this functionality without a binding loop? E.g. I want to save the current checked state of the checkbox in the settings singleton. I am using Qt 5.4 and Qml Quick 2. Regards, mcchu Don't bind it. Because the check box does not fully depend on Setting
