Dialog box doesn't have title bar, maximize button and close button

Halo_Hao

The program is compiled with Qt5 (FrameBuffer) whose dialog doesn’t have title bar, maximize button and close button. Also it doesn’t have an icon. All these worked fine on Qt 4 QWS. How to fix this on Qt5?
QMessageBox doesn’t have title bar, maximize button and close button either. That’s very inconvenient. I’m able to fix this via code on dialog created by myself, but I can’t control QMessageBox.

Hi,

That's because QWS was a minimal windowing system. The plugin you are currently using is not. You would have to use something like e.g. wayland if you need window management without using X11.

@SGaist
I heard about wayland but couldn’t find detailed introduction about it. I googled it and found little information and some doesn’t work as expected. Are there some official data about QT5 with wayland?

SGaist

Do you mean you went to both wayland with Qt5 and the Wiki entry ?

Halo_Hao

@SGaist I want to learn how to integrate wayland to Qt5. Is there any guide about this?

SGaist

Do you mean: build the QtWayland module ?

Halo_Hao

@SGaist Yes !

SGaist

It's explained here

@SGaist
I got error message after running git clone git://gitorious.org/qt/qtwayland.git:
[root@scdc 11]# git clone git://gitorious.org/qt/qtwayland.git

I'm wondering whether there is other git address of qtwayland?

SGaist

What was on gitorious is now on code.qt.io

http://code.qt.io/cgit/qt/qtwayland.git/

@SGaist
Should the module QtWayland can be built only when Qt5 supports OpenGl ES? How can I build QtWayland module based on Frame Buffer?
The target platform is x86:

SGaist

Did you install wayland first on your system ?

Halo_Hao

@SGaist The system I'm using is Ubuntu, and it doesn't install Wayland. I want to add Wayland to Linux Busybox built by myself, but I didn't add support of OpenGL to QT5 when I build it.

SGaist

You'll have to build Wayland yourself
