MainWindow generate buttons dynamically

63350541

I have such method in my class

int MyClass::generateGUI(std::vector<std::string> guiInfo, int argc, char **argv) {
    QApplication a(argc, argv);
    MainWindow w;
    for(std::string s: guiInfo){
      //  QPushButton *p = new QPushButton(s,);
    }
    w.show();
    return a.exec();
}

How can I add new button for each string in the vector?

Hi
Like JonB says. You better use a layout as else you must place them yourself as not tooverlap.

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    std::vector<std::string> list{"1", "2", "3", "4", "5", "6", "7"}; // the list
    auto central = w.centralWidget(); // get middle of mainwindow
    if (central) { //if it had one
        QVBoxLayout *layout = new  QVBoxLayout(central); // make layout
         for(const std::string & s: list){ // for all strings
          QPushButton *button = new QPushButton( QString::fromStdString(s) )  ; // make button
          layout->addWidget(button); // add to layout
         }
    }
    w.show();
    return a.exec();
}

By uncommenting your correct QPushButton line, and then adding the resulting button somewhere onto your MainWindow (give it a layout, put them on that, etc.)
