@JonB Yes by writing %%100 in translation removed warning

@Christian-Ehrlicher Ok I'll try, I'll inform as soon as there will be a result

@CLBSII You're welcome. What you did is, you centered the pixmap on your QLabel, but the label itself still had the QScrollArea- widget default alignment, which is topLeft :)

@qtnoob420 As I said: use real name of the attribute, not the word "attribute". Example: if you have attribute called "a" then do: a_dict[attribute] = self.dlg.a But it seems that you only have strings containing attribute names, right? Then you could do it like this: f = getattr(self.dlg, attribute) f() # Here we call attribute You do not even need a dictionary. One example for string in Python: s="abc" f=getattr(s, "upper") f() # prints ABC

@Gladiu said in Instancing multiple QLabels holding images and moving them independently: then how do i go about putting them on my window? You simply pass the parent widget (the one where the widget you're adding should be located) as parent: Qlabel label = new Qlabel("My cool label", this); // this is the parent here No need for addWidget.

@CEO @mrjj already wrote a line of code. What other code do you need?

The problem arises from the usage of the method m_model.setStringList(). The latter always clear the previous data, hence the index always reset upon its call. Solution: Use m_model.setStringList() only in the constructor to init the model. After that manually insert the row on the model and set the data for the respective row. This can be achieved with a simple modification in the slot method. MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) , ui(new Ui::MainWindow) { ui->setupUi(this); m_model.setStringList({"1","2"}); ui->comboBox->setModel(&model); } void MainWindow::on_pushButton_clicked() { m_model.insertRow(model.rowCount()); m_model.setData(model.index(model.rowCount()-1), "3"); } In the example above, "3" is appended to the list model without changing the current index from the QComboBox.

@AnneRanch changes in the template will automatically fall through to the widgets using it

You can add a custom compiler like shown here.

@SocketSackett said in how to resolve error of qmutex.h?: In general, companies file bug reports with other companies. I don't understand - you want that TQtC fills a bug report for every IDE or compiler where completely valid code does not compile or give any other errors/warnings?

CTest is the test runner. Yes that's the starting point. Then you can have separated functional tests where you validate the high level functionalities and finally integration tests where you ensure that the final application is working as expected.

Hi, Change the font size ? Without knowing how you create the report it's pretty hard to give you hints.

KDChart is another alternative but once again it's GPL or Commercial Charting is a hard task with so many possible customisations. In the past I cheated my way out of this problem using QWebEngineView and Google Charts (Box and whiskers example).

@mrjj , thank you for your response , i found the exemple very usfule , @VRonin, i resolved the probleme , juste may program it's note optimized , becouse i have a lote of condition , thanks anyways for the curios QString sFilePath = QFileDialog::getOpenFileName(this, tr("Open XML File ..."), "E:/", tr("XMLFile (*.xml)")); if(sFilePath.isEmpty()) { QMessageBox::critical(this, tr("Open File XML"), tr("the file is empty !")); return; } QFileInfo fileInfo(sFilePath); QString sFileXmlName = fileInfo.fileName(); // XML object QXmlStreamReader reader; //Fichier XML QFile fFileXml(sFilePath); //open XML on red only if(!fFileXml.open(QFile::ReadOnly | QFile::Text)) { QMessageBox::critical(this, tr("Open File XML"), tr("the file is not open !"), QMessageBox::Ok); return; } if (reader.readNextStartElement()) { if (reader.name() == "Calib"){ while(reader.readNextStartElement()){ if(reader.name() == "CalibPt"){ while(reader.readNextStartElement()){ if(reader.name() == "calib"){ QString s = reader.readElementText(); ui->lineEdit_19->setText(s); } else if(reader.name() == "conv_"){ QString s = reader.readElementText(); ui->spinBox_1->setValue(s. toInt()); } else if(reader.name() == "conv_1"){ QString s = reader.readElementText(); ui->lineEdit->setText(s); } else if(reader.name() == "calib_1"){ QString s = reader.readElementText(); ui->lineEdit_9->setText(s); } else if(reader.name() == "conv_2"){ QString s = reader.readElementText(); ui->lineEdit_2->setText(s); } else if(reader.name() == "calib_2"){ QString s = reader.readElementText(); ui->lineEdit_10->setText(s); } else if(reader.name() == "conv_3"){ QString s = reader.readElementText(); ui->lineEdit_3->setText(s); } else if(reader.name() == "calib_3"){ QString s = reader.readElementText(); ui->lineEdit_11->setText(s); } else if(reader.name() == "conv_4"){ QString s = reader.readElementText(); ui->lineEdit_4->setText(s); } else if(reader.name() == "calib_4"){ QString s = reader.readElementText(); ui->lineEdit_12->setText(s); } else if(reader.name() == "conv_5"){ QString s = reader.readElementText(); ui->lineEdit_5->setText(s); } else if(reader.name() == "calib_5"){ QString s = reader.readElementText(); ui->lineEdit_13->setText(s); } else if(reader.name() == "conv_6"){ QString s = reader.readElementText(); ui->lineEdit_6->setText(s); } else if(reader.name() == "calib_6"){ QString s = reader.readElementText(); ui->lineEdit_14->setText(s); } else if(reader.name() == "conv_7"){ QString s = reader.readElementText(); ui->lineEdit_7->setText(s); } else if(reader.name() == "calib_7"){ QString s = reader.readElementText(); ui->lineEdit_15->setText(s); } else if(reader.name() == "conv_8"){ QString s = reader.readElementText(); ui->lineEdit_8->setText(s); } else if(reader.name() == "calib_8"){ QString s = reader.readElementText(); ui->lineEdit_16->setText(s); } else reader.skipCurrentElement(); } } else reader.skipCurrentElement(); } } else reader.raiseError(QObject::tr(".")); } I have to change the names of the subchild, otherwise it will not work.

@SPlatten Unless you know better than I or see any problems occurring: so far as I know, first chance exceptions occur "naturally" and can be ignored. Debuggers report them, VS used to do so all the time, you don't have to worry. It is probably happening down in the guts of the file dialog code for getting stuff to display, e.g. maybe looking at network (but that's only a guess). And just btw, RCP server unavailable is not the right title: you are looking at an RPC server, which is quite different from RCP :) Better title now :)

@SPlatten said in QTableView, QSortFilterProxyModel row selection: is there an example which demonstrates how to use these? const QItemSelection proxySelect = mptvSDrecs->selectionModel()->selection(); QModelIndexList objIndexes = mpsfpSDmodel->mapSelectionToSource(proxySelect)->indexes();

@Yina no this iss not possible. For example in general the connection can either be established via USB or simple GPIOs. If you know its connected via USB you need to use some usb library or the platforms native API for example to get such information.

Thanks @JKSH for the clarification :)
