@ichidan Hi and welcome to devnet forums The versions are determined by availability on the repository servers. Since there are a "mass" of different compiler versions around Qt libraries are only build for some selected versions. The best is to install the same version of a pre-built Qt libs as the compiler is you have installed. Especially with MSVC compiler there is almost no compatibility between subsequent versions. However, IIRC there is a compatibility between MSVC2015 and MSVC2017 versions. For sure there is no compatibility to or between previous versions. Also you cannot mix 32-bit and 64-bit versions. However, since you have a qt-enterprise version, it should mean that you have a commercial version with license, if I amnot mistaken. When you have a commercial license you are entitled to get support from the commercial hotline. This is the open source forum.

Hi, Can you show your class definition ?

Hi, Did you also install Qt for MSVC2013 ?

Hi, QtWebKit has been deprecated in 5.5 and won't be released as prebuilt module starting with 5.6. You still can build it yourself from sources though. You can find Qt 5.5.1 here

@SGaist Thx I will give it a try. I am closing it as solved since the issue has been reported for bug-fixing and there are other options to make it work.

You're welcome ! Since you have it working now, please mark the thread as solved using the "Topic Tool" button so that other forum users may know a solution has been found :)

@jsulm said: @Pixtar You can use Visual Studio 2013 Community which is more or less same as Professional. Thanks for the hint. :D

Hi and welcome to devnet, Do you have by any change QT_FATAL_WARNINGS defined ? If not, can you try the same thing with the 5.6 beta ?

You can try to add your static libraries like this: LIBS += PATH_TO_LIB_DIR/libLIBNAME.lib

Well, that would be part of the logic of the filter: first step, close the dialog, second handle 8. In any case, your idea of not calling accept on the event should result it in being forward to your MainWindow

Did you create a kit that uses your static Qt build ?

i solved problem by download other version of Qt Qt 5.5.0 for Windows 32-bit (MinGW 4.9.2, 959 MB) THANKS
