Creating a form at runtime

[dolevo]

Hi guys,

I create a form at runtime like the following:

@ QWidget *form=new QWidget(this);
QGridLayout *lay = new QGridLayout();

    lay->addWidget(new QLabel("Select a User:"), 0, 0);
    QStringList userlist = db->mpRetrieveUserColumn("username");
    userSelectComboBox = new QComboBox();
    foreach(QString str, userlist)
        userSelectComboBox->addItem(str);
    lay->addWidget(userSelectComboBox, 0, 1, 1, 2);

    QPushButton *btn = new QPushButton("OK");
    connect(btn, SIGNAL(clicked()), this, SLOT(mpOnUserSelected()));
    lay->addWidget(btn, 2, 2);
    form->setLayout(lay);
    form->show();@

I call this in the main thread where I have the ui. However, this show the widget on the existing form. However, I want to have this form like a new modal form on top of the main form. I have been looking into the documentation but couldn't find it yet. Could you please give me a hint?

Try using, e.g., a QDialog instead of QWidget if you want a top-level widget. You could also use QWidget and specify NULL as parent in the constructor.

My Lord,
Awesome! I never thought about giving NULL parameter but it make a lot sense. Thanks a lot.

The manual is quite explicit about this ;-)

If parent is 0, the new widget becomes a window. If parent is another widget, this widget becomes a child window inside parent.
