No taskbar entry for QDialog using console application

Neshom

I am writing a Qt Console Application using Qt Creator 4.6.0 in Linux. I would like to show a QDialog but I do not want it to

show an entry on taskbar, and
steal focus from other windows.

How can I do this?

I found kind of similar question, but the solutions does not work for me as it seems that I can's use this in console application.

Here is what I have so far which shows the dialog but it neither hides it form taskbar nor prevents it from stealing the focus:

    QDialog splash;
    QVBoxLayout *laySplash = new QVBoxLayout(&splash);
    splash.setAttribute(Qt::WA_ShowWithoutActivating);
    splash.setWindowFlags(Qt::Tool | Qt::FramelessWindowHint | Qt::WindowStaysOnTopHint);
    QLabel *lblText = new QLabel;
    laySplash->addWidget(lblText);
    lblText->setText(QString::fromStdString("test"));
    QTimer::singleShot(1000, &splash, SLOT(close()));
    splash.exec();

What do you want to achieve exactly?
Console applications just interact with the console normally and have no visual elements.

Hi @Neshom,

I'd fully agree to @raven-worx that console apps shouldn't use graphical elements.

Just a side node:

lblText->setText(QString::fromStdString("test"));

That looks odd. You're converting a char array to a std::string to convert it to a QString. Better use:

 lblText->setText(QStringLiteral("test")); // for string constants
 lblText->setText(tr("test")); // for user output - makes it translateable

I want the console application to show dialog which it does. However, it shows an entry on the taskbar for the dialog which I am trying to get rid of. Any suggestion?

E.g. https://stackoverflow.com/questions/4055506/qt-hide-taskbar-item seems to offer several ways (flags) to achieve this?

None of these solution works for me. I am using Lubuntu. Can this be the reason?

@Neshom
I would guess that is indeed the reason if none of those work! It always helps if you tell us which OS you are under, especially if it's not Windows! I would imagine this is a desktop-thing, so more than Lubuntu what is probably relevant is which desktop manager you are using. And it may be that your manager does not allow you not to have an icon....

I am using Linux - Lubuntu which has LXDE. Is there anyway to fix this? Is there any other way in QT to show a frame-less window/dialog/message/label/etc without a task-bar entry?
