Problem with mainwindow (the buttons desapear)

mrjj

Hi
I don't see anything wrong with code.
The picture you shown.
Seems just to be Mainwindow.
Not the Posicionador_Manual_1 dialog

So the dialog do show?

BrunoVinicius

That's the issue.
The mainwindow turns white even when i do not click in any button, just pass the mouse over it.
This is the two windows after the problem.
I am suspecting of a problem with compatibility in my windows or something like that. i don't know for sure.

error

Hi,

i tried to do a simple window, with just one button to close this mainwindow and i am geting the same problem, the window turns white. I will reinstall my Qt with a an older version that have 64 bits version and see what happend.

thank you anyway!!

@BrunoVinicius
Ok it does seem a bit strange.
Just moving mouse over window should not make it white/non responsive.

If you open any of the many examples. do they run?

BrunoVinicius

I did not try exemples, but i followed some videos in youtube, and did just the same program the video shows, and give me the same error. Like you said, it does seem a bit strange.
when i reinstall the Qt, i will post the result.

Thanks!

@BrunoVinicius
ok before u reinstall,maybe try example just to see?

BrunoVinicius

hi again,

like you said i tried some exemples and the same error. I tried childwidget, most basic impossible!!!

I try to install some older version, but i had problem with the compiler.
i don't know what to do anymore.

Hi,

What if you use the 64 bit version of Qt ?

mrjj

Also, make sure to try to disable your virus scanner for a moment to test.

Hi,

SGaist, i downloaded a Qt 5.0.2-msvc2012_64-x64-offline, but i had some problems with the compiler, because its not integrate, i assume. Do i need to desinstall my current version to install this one? And how i can configure the compiler?

mrjj, i do not have a antivirus runing in the moment, so that's is not the problem.

thanks a lot guys!!

SGaist

Because that's a version for Visual Studio 2012 and you have 2013. You can't mix and match compilers on Windows, they are not compatible one with the other.

Just download the 64 bit Qt 5.5.1 for Visual Studio 2013

Hello,

i know it is not the topic problem but,
i installed Qt 5.5.1 64 (MSVC2013) version, and know in Build and Run, Qt versions and Kits configurations have problem. In compilers, the program just detect Micrsoft Visual C++ Compiler 14.0. How i configure and do i have to install another program?

Thanks

Hello again,

i reinstall Qt, using "qt-opensource-windows-x86-mingw491_opengl-5.4.0" and works properly.
Thanks anyaway guys.

SGaist

Out of curiosity, did you by any chance change from Visual Studio 2013 to Visual Studio 2015 ?

Also, why install an older version of Qt and not the current ?
