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 ?

[high_flyer]

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

[kongkong163]

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.

I just want to have a pop widget like the widget that "show open applications" after click options on the device. So any one has done this, please give me some suggests.
Any reply will be appreciate.

Hi,
maybe i know what you would.

If it's not late:

QDialog *yourDialog= new QDialog(this, Qt::Popup | Qt:: Dialog);

// create your dialog ....

yourDialog->exec();


It works for me like a dialog without the title bar at the top, and without buttons at the bottom and you can click outside the dialog window, it won't disappear.
I hope i could help

You could as well simply use FramelessWindowHint / StayOnTop with any QWidget. This will make ur widget stay and also wont hide like popups.

Or you can say a QWidget to work as a QDialog

QWidget *yourWidget = new QWidget(this, Qt::Popup | Qt:: Dialog);

//create your widget ....

yourWidget ->setWindowModality(Qt::WindowModal);
yourWidget ->show();

That's it.
