[Solved] Qt Apps look ugly in Windows 8 Consumer Preview

Ghost

I opened SMPlayer; the UI looked Classic-ish. Then, I also checked Qt Creator, and VLC - same situation. I have attached a screentshot. Please check it, and see if anyone faces the same problem.
Let me remind you that all other apps look just perfectly fine.
I hope it's just a problem with my setup. Anyways, please shed some light on this.!http://i.imgur.com/dKvOC.jpg(Ugly UI of Qt Apps)!

You mean the styles? (QPlastique, etc) I've tryed some applications with them and they worked fine. Try running with compatibility mode. Also, did this happen on Developer Preview?

I am talking about the controls - buttons, drop down, checkboxes, etc. They all look old Win98 style: classic-ish. I haven't applied any theme - it's the default UI. That certainly should look normal, which is the case in other applications. Here is an "a comparison between default look of Notepad++(Non-Qt) and Clementine(Qt)":http://i.imgur.com/SL8V6.jpg

And I am not aware of Developer Preview. I had installed it only for a brief time, during which, I hadn't install any Qt app.

What happens if you specify the Vista style explicitly?

Ghost

You mean setting the Windows Aero style explicitly in the Personalization option? I have already done that, without any result.

I was having the same problem. I tried setting the QWindowsVistaStyle explicitly first, but it made no difference.

Then I tried setting the QWindowsXPStyle style like this: QApplication::setStyle(new QWindowsXPStyle); and it seemed to work.

The look now appears to be that of a Windows 7 or 8 program, not Windows XP. I don't know why.

Ghost

Ah. The harder I try to forget XP, the more it comes and hit me!
Well. That could work for the applications that we design. What about the already-existing apps? I surely don't want to see those boring controls, now that I am used to KDE and Windows 7 interfaces.
I hope that someone can find some solution to this.

Has anyone got solution to this?

As windows 8 is not officially out, I assume Qt does not support it officially for styles etc.
Till Qt does not officially supports it, you have to live with work arounds.

Ghost

Yes. Ok. I got that point of view after reading several other posts related to Windows 8 Metro app development. It's fair enough that Qt can't support Windows 8 right away, Windows8 being just in a beta stage.
I am eagerly waiting for the official support now. Meanwhile, I will reinstall Windows 7 as Win8 hasn't been more useful to me anyways.

The problem was that Qt did not check for Windows version correctly (hence the checks for >= Windows Vista or >= Windows XP failed). This has been fixed in Qt 4.8 by my merge request https://qt.gitorious.org/qt/qt/commit/1ef309e964753105e14a8c223a1b59c0cbd9369b

Wow. I am glad that I got a solution even after such a long time! I had myself forgotten this post.
Anyways, while I am already back on Windows 7, I am sure someone else will find this solution helpful.
