QDialog loses OSX sheet style once QComboBox is activated

notrodash

In my application I have a QDialog which contains a QComboBox. Whenever this QComboBox is triggered, the QDialog title bar appears and it turns into a window which can be moved around. When I hit ESC the dialog performs the closing animation of an OSX Sheet. Is there something I can do to prevent this? Is this a bug? This did not happen in Qt 4.x.

Code for screenshots below:
@#include <QtWidgets/qapplication.h>
#include <QtWidgets/qmainwindow.h>
#include <QtWidgets/qdialog.h>
#include <QtWidgets/qgridlayout.h>
#include <QtWidgets/qcombobox.h>

int main(int argc, char** argv){
QApplication app(argc, argv);

QMainWindow* mainWindow = new QMainWindow();
mainWindow->setWindowTitle("This is the main window");

QDialog* dialog = new QDialog(mainWindow);
mainWindow->setFixedSize(QSize(300, 100));
mainWindow->show();
dialog->setWindowFlags(Qt::Sheet);
dialog->setWindowTitle("This is the dialog");
dialog->setFixedSize(QSize(200, 70));
QGridLayout* layout = new QGridLayout(dialog);
dialog->setLayout(layout);
QComboBox* combo = new QComboBox(dialog);
combo->addItem("Item 1");
combo->addItem("Item 2");
combo->addItem("Item 3");
combo->addItem("Item 4");
layout->addWidget(combo);
dialog->open();

return app.exec();

}@

Hi and welcome to devnet,

This sounds like a bug, you should have a look at the "bug report system":http://bugreports.qt-project.org/issues/ to check whether it has already been reported. If not, you could open a new bug report.

Bug reported on this forum are likely to not get noticed as only few Qt developers follows it (it's more user oriented)
