@Pradson said in Help regarding QRemoteObject.: Would you like to add any point from your end otherwise I will have to close this topic. I have nothing to add to this. I'm curious: why do you need Windows API in a web application?

As clearly stated in the doc, use QFont::NoAntialias instead: someFont.setStyleStrategy(QFont::NoAntialias);

@AnneRanch I need to rewrite this post. This is an example of how Qt builds class constructor which includes "form" ( I am not so sure naming class and form same name....). Widget::Widget(QWidget *parent) : QWidget(parent) , ui(new Ui::Widget) { ui->setupUi(this); } This is how the actual class definition looks QT_BEGIN_NAMESPACE namespace Ui { class Widget; } QT_END_NAMESPACE class Widget : public QWidget { Q_OBJECT public: Widget(QWidget *parent = nullptr); ~Widget(); private: Ui::Widget *ui; }; #endif // WIDGET_H Here is how my "form-less" class definition partially looks : class CCC_MdiChild : public QTextEdit { Q_OBJECT public: CCC_MdiChild(); etc etc and its constructor CCC_MdiChild::CCC_MdiChild() { setAttribute(Qt::WA_DeleteOnClose); isUntitled = true; } I have no issues adding "form.h" to the project....using QDesigner and QCreator I need help adding "form.h" to the actual C++ code - class definition and to the default constructor. Plain C++ - anybody ? I'll keep this original post for a spell... I have decided to add "form" to the project I got as far as this and I have no idea what class is missing in the code [image: af8cfe10-51db-4387-8031-76d97d0d399d.png] I got stomped by adding " ui_form" header, and recall discussing that long time ago. I guess this time it is "just the way it is "

Hi, Sounds like you would need an event filter.

@freemanl144 I have no idea, but I am saying i cannot/should not have anything to do with running the pyside2-uic command.

@SPlatten What I do is I make sure to cast to numbers and no nulls in the query eg. SELECT CAST(IFNULL(kompletacja,0) AS DECIMAL(10,5)) as 'kompletacja' FROM TABLE

The QMfcApp is created in the CWinApp::InitInstance() mf as the first thing it does. QMfcApp::instance(this); the program has its own _tWinMain() that invokes AfxWinInit() to start MFC, and then runs InitInstance, and then invokes the main function of the program as a modal dialog using CDialog::DoModal(). It would appear that the Run() mf which contains: int result = QMfcApp::run(this); delete qApp; return result; is never actually invoked! No - I didn't write this. Perhaps not quite the normal CWinApp application. I'm not sure where to go from here!

Thanks; I already know what you mean ; I'm just interested in this, and i read many blogs that introduce the difference between QStyledItemDelegate and QItemDelegate, it just write "use current style". The most important reason is that I have been relatively idle recently，hahaha.😂

@kayakaan02 said in How to store Audio Input in array?: The QByteArray that readAll() returns is empty That is not possible provided you call readAll() in the slot for readyRead(), just as I see you have marked as the correct answer from @jsulm above..... If you call readAll() anywhere else it could be empty. Your code cannot be the same as the example you quote since that does not use readAll().

Thank u for the support the problem is because of some internal admin permissions because of that qt was not able access the dll's.

configure.bat ... -D _WIN64

@lukutis222 Don't use QWidget as top level widget. Always use QMainWindow for main application window and document windows. Otherwise use QDialogs.

@mchinand Thanks that was a good advice. I looked it up, this issue was already created, but the priority is "somewhat important".. so probably will remain a bug unless more people complain https://bugreports.qt.io/browse/QTCREATORBUG-22492

Makes sense. Thank you very much for clarifying. I read a little bit about printf in the ESP32 documentation (external device that I have connected) https://esp32.com/viewtopic.php?t=3447

@lukutis222 said in Converting string to hex before inserting into QTextEdit: Is this an error in QT documentation? It talks about toHex but then in the example it uses fromHex no, not really. The example uses fromHex in the first line to fill the data of the QByteArray, which is internally a char array. QByteArray does currently not support initialiser list construction, so the documentation uses the fromHex(string) static function to create and fill the QByteArray in one line
