how to make the pop up widget as modal ?

[kongkong163]

Hello, I use these code to create a pop up widget and set it modal

QWidget* popUp = new QWidget(this, Qt::Popup);
popUp->setWindowModality(Qt::WindowModal);
QRect rect = QStyle::alignedRect(layoutDirection(), Qt::AlignBottom, QSize(width(), height()/3), geometry());
popUp->setGeometry(rect);
popUp->show();

however, after the pop up widget show, I click the place that outside the pop up widget but in the background widget, the pop up widget disappear.
So what should I do to set the pop up widget modal ?

From the docs:

This property only makes sense for windows.

A window is a widget that isn't visually the child of any other widget and that usually has a frame and a window title.

Why don't you use a QDialog?

thanks for quick reply.
So can the dialog show as pop up ?

yes, read the docs!
Call QDialog::exec() to show it as modal.

if I use this code

QDialog* popUp = new QDialog(this, Qt::Popup);
...
popUp.exec();

it remains the same as the QWidget.
And If I use this code

QDialog* popUp = new QDialog(this);
...
popUp.exec()

it becomes modal, but it not like a pop up widget
it is full screen.
Both of them were not what I want.

it remains the same as the QWidget.

Hmm...
try explicitly setting modality setModal(true);

I would expect it to be modal, and based on the docs, it should be.

If its not, it might be a Qt bug - but maybe some one else can comment on this.
