  @SGaist ,

  Yes, I have now also confirmed on the failing line:

  qrc:/CResetPasswordDialog.qml:4 module "QtWebEngine" is not installed

  We have:

  CResetPasswordDialog.qml:

  import QtQuick 2.6 import QtQuick.Layouts 1.3 import QtQuick.Controls 1.4 import QtWebEngine 1.5

  (Changing import QtWebEngine 1.2 to import QtWebEngine 1.5 as specified in documentation for QtWebEngine under Qt 5.9 (https://doc.qt.io/qt-5/qtwebengine-qmlmodule.html)

  We also have QT += webengine in our .pro file.

  Hello,
  I have found the solution. Now, instead of directly deleting the widget I use deleteLater() so the widget is scheduled to be destroyed when the control returns to the event loop. The final code can be found here and it looks like:

  Custom widget:

  #ifndef BUTTON_H #define BUTTON_H #include <QWidget> namespace Ui { class Button; } class Button : public QWidget { Q_OBJECT public: explicit Button(int n, QWidget *parent = 0); ~Button(); private slots: void removeRequested(); signals: void remove(Button* button); private: Ui::Button *ui; }; #endif // BUTTON_H #include "button.h" #include "ui_button.h" Button::Button(int n, QWidget *parent) : QWidget(parent), ui(new Ui::Button) { ui->setupUi(this); ui->pushButton->setText("Remove button "+QString::number(n)); addAction(ui->actionRemove); connect(ui->actionRemove,SIGNAL(triggered()),this,SLOT(removeRequested())); connect(ui->pushButton,SIGNAL(clicked()),this,SLOT(removeRequested())); } Button::~Button() { delete ui; } void Button::removeRequested() { emit remove(this); }

  Main gui:

  #ifndef BUTTONSTACK_H #define BUTTONSTACK_H #include <QWidget> #include "button.h" namespace Ui { class ButtonStack; } class ButtonStack : public QWidget { Q_OBJECT public: explicit ButtonStack(QWidget *parent = 0); ~ButtonStack(); private slots: void on_addButton_clicked(); void remove(Button* button); private: Ui::ButtonStack *ui; int total_buttons; }; #endif // BUTTONSTACK_H #include "buttonstack.h" #include "ui_buttonstack.h" ButtonStack::ButtonStack(QWidget *parent) : QWidget(parent),total_buttons(0), ui(new Ui::ButtonStack) { ui->setupUi(this); } ButtonStack::~ButtonStack() { delete ui; } void ButtonStack::on_addButton_clicked() { Button* button(new Button(total_buttons++)); ui->qvboxlayout->insertWidget(0,button); connect(button,SIGNAL(remove(Button*)),this,SLOT(remove(Button*))); } void ButtonStack::remove(Button* button) { ui->qvboxlayout->removeWidget(button); button->deleteLater(); }

  Main:

  #include <QtGui/QApplication> #include "buttonstack.h" int main(int argc, char** argv) { QApplication app (argc, argv); ButtonStack bs; bs.show(); return app.exec(); }

  @mrjj

  Have a look at this sample
  http://www.bogotobogo.com/Qt/Qt5_Downloading_Files_QNetworkAccessManager_QNetworkRequest.php
  It uses a small helper class
  class Downloader : public QObject
  to manage the data it downloads. It responds to the finished signal.
  Here it stores to file but you can as well store in ByteArray or whatever is needed.

  I already have a class doing this job - as I said in the begining I can already save my reply data to file that can be read/used from anywhere in one signal slot connection, I just want to do the same thing without using a file so it can be read/used from anywhere in a single connection. If my class data object that has been assigned (or appended to) the value of reply's byte array is always empty when called, say from outside of the class (after download), meaning I have to re-download everytime I need the same data, then the reply data is not stored to my object is it?

  the difference is due to a modification of the Composition Mode of the QPaineter wich was painting the objects (QPainter::QCompositionMode_Darken on the first screenshot and QPainter::QCompositionMode_SourceOver on the second one)

  So not an evolution of Qt painting behavior, but a modification of the app's code.

  Hi @gabor53

  you cannot call the non-const function addNewImage in the const function setModelData. So you have to remove const from setModelData or add const to addNewImage.

  @Sunfluxgames said in QT load .dll but not calling resolve returns false:

  So getting the lib or header for that is out of the question. I did hack a lib/header together with those functions and faked the .dll call and put the main .dll inside that folder and it seem to work but this was based off a C++ console project not a QT project.

  Qt is C++ library, as @jsulm said, so there's nothing different to do.

  why (crypto->*SetKey) around this? * is a call pointer to method?

  Yes, ->* is pointer-to-member call. Because the you get a method address (as it's a __thiscall) and you need to bind an object to actually call the function.

  CCrypto * crypto; //< From wherever that object comes // mine comes from Qobject wouldnt you need to create a new on heap

  Heap or stack doesn't matter here. The thing is you need to have an initialized object from the type Crypto, which from your description I don't see how you will obtain. The problem is you need to know how big the object is, so to allocate enough memory, then manually call the constructor (resolved as in the above example) and finally call the destructor (again manually) and free your memory whenever you've finished with the object. It's a tad more complicated than calling a simple C-style function and without a header you have to do a some digging through the library's assembly to determine how large is each class's instance so to know what to put in the fake-header.

  You cross-compiled Qt for the OpenGL ES2 backend, this is one of the backends that work without any window manager.

  If you want one you need to either use the xcb backend or the wayland backend.

  Note however that UDP and TCP checksums are computed in the same way i.e. at least 40 years old technology but seems to work fine on internet...
