General and Desktop

Okay, I think I found the tool I was looking for. In Eclipse with the Web plugin you can literally right click on an xsd file and tell it to generate an xml file that, once it is generated you can add namespaces to the file. From there you can edit the file using a structured editor to add elements that correspond to the schema and various namespaces you added. This allows a structured creation of an xml file from the schema(s) you have selected. Eclipse will also keep validating against the schema so you will show errors if you enter in an incorrect node. So while initially I was looking for a programming solution, I was really looking for a suitably featured xml tool. I am sure there are others out there. I think visual studio has some tools for this.

@koahnig it works

Sure did, but that I can see, none of those projects make use of dynamically loading some changed Scxml. Sure, they load one up dynamically, but once it's loaded it's done. Some of the examples even load from a resource file; so to me, that makes it even less dynamic. I did find a use case however that's fairly straightforward: A generic state machine loader that does nothing more than publish known and active states, and processes events. I'd sure appreciate it if you could try to answer some of my outstanding questions here, perhaps with some example. Thanks!

@jsulm Thanks it works.

@aha_1980 @jsulm @SGaist @Kent-Dorfman It all boiled down to store some information in QSettings. Reading a QJsonDocument from QSettings posed an issue, however reading QString from QSettings was possible. Now, I found out how work with QJsonDocument and QSettings, I no longer need to wrong transfer Image in QString. As a work around, I changed Image to Byte Array, changed this Byte Array to hex Array and later changed this Hexed Byte array to QString and stored. But, this is all not required now. Thanks for your inputs.

@mrjj thank's I knew the problem with myLib.errorString(); @jsulm thank's the path was incorrect

I just wanted to locate the splitter so that all the table columns are visible. I tried using QSplitter::setSizes() with the table width but it wasn't updated right after creation. I solved it by overriding the table's resizeEvent() and emitting a signal to the parent widget

Hi and also https://doc.qt.io/qt-5/qtimageformats-index.html

@Pada_ said in QTableView delegate insert Error.: Motion is created so that you can modify it. What do you mean by that ? Im not sure what you expect/want to happen in B. version.

@mrjj thanx. I have change bug report. PS: The bug appears even when first create list with attached widgets then bind it to QGraphicsWidget on scene.

for qt @Stefan-Monov said in Style the scrollbar of QListView: Hi sNiff3ls. We had the stippled-scrollbar problem in our app too. Solved it with: myWindow->setStyle(new QPlastiqueStyle()) Since we're using CSS to customize the entire look of the app (just like you), making your app use QPlastiqueStyle doesn't affect anything other than the scrollbar stippling (and a few other minor details). If you weren't using CSS, then QPlastiqueStyle would make your app look totally different, but in this case I recommend you just use it as a hack, because QPlastiqueStyle's scrollbar-drawing implementation doesn't use stippling, whereas the default style on windows (QWindowsStyle) does. I consider it a bug in Qt that this is necessary. QScrollBar should be fixed to respect the css fully. 2019 now, in python 3 and pyqt5, use following code: # keys = QStyleFactory.keys() self.setStyle(QStyleFactory.create('Fusion')) refer link here: https://doc.qt.io/qt-5/sourcebreaks.html#changes-to-qstyle https://doc.qt.io/qt-5/qstylefactory.html#create

@sierdzio Aha! I found https://doc.qt.io/archives/qt-5.7/supported-platforms-and-configurations.html (need change URL for older version)

@Hetal For a question like this you should always state which platform you are on. Google for qt5 threadid. There are a number of hits to read, e.g. https://www.qtcentre.org/threads/2369-How-can-I-get-the-thread-ID-out-of-QThread, https://stackoverflow.com/questions/23452218/proper-use-of-qthread-currentthreadid, others also. https://doc.qt.io/qt-5/qthread.html#currentThreadId Returns the thread handle of the currently executing thread. Warning: The handle returned by this function is used for internal purposes and should not be used in any application code. Note: On Windows, this function returns the DWORD (Windows-Thread ID) returned by the Win32 function GetCurrentThreadId(), not the pseudo-HANDLE (Windows-Thread HANDLE) returned by the Win32 function GetCurrentThread(). I imagine your attempted usage/findings are related to this?

I dont know why, but if I set the conexion between server and client first and then I call the function startSerialPort(), the reading speed is the normal. But this method just works with the first conexion. The second conexion already experiment the decrease of the reading speed. void MyServer::startSerialPort() { mipuerto2 = new MySerialPort; msgRec = new MensajeRecibido; msgSent = new MensajeEnviar; connect(mipuerto2, SIGNAL(msgChanged(QByteArray*)), this, SLOT(getMens(QByteArray*))); connect(mipuerto2, SIGNAL(msgChanged(QByteArray*)), this, SLOT(idMensaje(QByteArray*))); connect(msgSent, SIGNAL(tienesMensaje(QString*)), this, SLOT(setRecibido(QString *))); mipuerto2->openSerialPort(); } qDebug()<<socketDescriptor<<"Connecting... "; socket = new MySocket(socketDescriptor); controlador++; QThread *thread = new QThread; qDebug()<<thread->currentThreadId(); connect(this, SIGNAL(mensChanged(QByteArray*)), socket, SLOT(getMsg(QByteArray*))); connect(socket, SIGNAL(mensajeEnviarSocket(QByteArray*)), this, SLOT(sendMens(QByteArray*))); connect(socket, SIGNAL(disconnected()),thread, SLOT(quit()) ); connect(socket, SIGNAL(disconnected()), socket, SLOT(deleteLater())); connect(thread, SIGNAL(finished()), thread, SLOT(deleteLater())); connect(thread, SIGNAL(started()), socket, SLOT(funcionamiento())); connect(socket, SIGNAL(disconnected), this, SLOT(desconectar())); socket->moveToThread(thread); thread->start(); if(controlador==1){ startSerialPort(); }else if (controlador>1) { mipuerto2->closeSerialPort(); delete mipuerto2; startSerialPort(); }

@rahulvishwakarma Search for plugins/platforms/libqxcb.so and do ldd PATH_TO/libqxcb.so and post the output here.

@sonichy My guess is: you did not install the package containing it.
