I want to open a new window when a push button is clicked but it gets it on the main window

[Rahma]

void MainWindow::on_addhabit_clicked()
{

addhabit *habitwindow=new addhabit(this,this);
habitwindow->show();
}
in the main window when addhabit button is clicked it should open a new different window but instead it open it on main window that both there items appear together

@Rahma said in I want to open a new window when a push button is clicked but it gets it on the main window:

addhabit *habitwindow=new addhabit(this,this);

I guess addhabit is a QWidget?
Simply do not pass parent (this) to it then it will be a window.
See https://doc.qt.io/qt-5/qwidget.html#QWidget :
"If parent is 0, the new widget becomes a window. If parent is another widget, this widget becomes a child window inside parent."

@jsulm

@Rahma

addhabit *habitwindow=new addhabit(this,this);

But if you don't pass a parent (this) please keep in mind that you'll need to manage your memory allocation (new) yourself...

@Rahma you need to share more of your code, sharing just snippets is making others harder...

As you posted before:

void MainWindow::on_addhabit_clicked()
{
...

that will work if you have a QPushButton object called addhabit also defined in your MainWindow class

The easiest and IMOH cleanest solution is to give the underlying QWidget Constructor the Window tag

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QWidget w0;
    w0.show();

    QWidget *w = new QWidget(&w0, Qt::Window);
    w->show();
    w->resize(200,200);
    w->raise();

    return  a.exec();
}
