QFileDialog not appearing on the top even after using different window flags

[Sherlin N G]

When the user clicks the browse button I'm doing
QFileDialog *img = new QFileDialog;
img->show();
The Dialog box appears but next time when the user clicks browse button the DialogBox is minimised/opening behind by mainwindow.I tried setting different window flags but they are not working.

Give it the mainwindows or your central widget as parent in the constructor.

I tried doing this
MainWindow::MainWindow(QWidget *centralWidget) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{

ui->setupUi(this);

...........
}

getting error /home/tel/Ui_IMP/mainwindow.cpp:17: error: invalid use of non-static member function
ui(new Ui::MainWindow)

@Sherlin-N-G
It's the QFileDialog constructor you're needing to change, to give the dialog a parent. You're supposed to be calling e.g. new QFileDialog(mainWindow) or new QFileDialog(mainWindow->centralWidget).

i tried
QFileDialog *file = new QFileDialog(MainWindow);
its showing "expected primary-expression before ')' token"

also tried this

/home/tel/Ui_IMP/mainwindow.cpp:73: error: expected primary-expression before ‘->’ token
QFileDialog *file = new QFileDialog(MainWindow->centralWidget);

@Sherlin-N-G
MainWindow is a class. You need to pass an instance, the instance of your MainWindow. That's why I wrote mainWindow (a variable of yours, whatever it is), not MainWindow (the class).

@Sherlin-N-G said in QFileDialog not appearing on the top even after using different window flags:

QFileDialog *file = new QFileDialog(MainWindow->centralWidget);

is there really a variable called MainWindow?!
If you are executing this code from within any widget, just pass this instead.
