Does qt have to be rebuild for it to detect new plugins? I have been trying to get any examples of plugins to work in my Qt environment but have been unsuccessful. For instance, the plug and paint plugin example should be straight forward out the box but I can´t even get that to work. I´ve recompile the plug and paint plugins and see the shared library. I bring the plug and paint application up and I get and error during compile. It indicates ¨:: error: cannot find -lpnp_basictools¨. I tried to place the library under the qt plugin and still got no success. Please help!!!
well, download the sources, for Qt 4.7.0 and creator 2.0.1, read the README and open a visual x64 cmd. It take long time... Generating debug and release in one shot don't work for me. If you want to compile in a specific directory, out of the source tree, you'll need perl in the PATH. I don't find how to patch the binaries to make a good package, without the original source tree write in the binaries... not useful in my case, for the moment.
a few questions and remarks:
openssl: I disable the option cause this lib is not installed in my laptop. I'll try later with the binaries from "slproweb":http://www.slproweb.com/products/Win32OpenSSL.html
dbus: I don't know for the moment how to do. Is it possible on windows?
debugging helpers: I have to go in the ...\qt-everywhere-opensource-src-4.7.0\qtc-debugging-helper dir and make it "by hand" (qmake and nmake). From the creator options ui it doesn't work, and the log said ok ?? strange, but perhaps a mistake... and don't know.
debugging helper: debug a 32bits app with helpers on creator 64bits + CDB 64bits ... raise exception and don't work ?
debugging helper: infact with and without helpers, in 64 bits mode in this case, I don't see what the "plus" ;) I need to read more docs eventually
CDB: ok the first time it's really long to wait the loading but next times it's not so bad. from visual it's faster ok, but not so bad ;)
jom is a separate package, I don't try to install it, but you can find a pointer "here":http://qt.gitorious.org/qt-labs/jom/#more
I'd like to know how to do that with mingw-x64, and Windows SDK 7.1 (without visual installed), I'll try to do it in my spare time, if someone have experiences about that, post it :) It's so easy with linux...
I don't understand why 64bits windows binaries are not proposed by Qt, and yes the windows way to jump 64bits is rock and roll, but Qt is cute cause of its portability and user friendly use....
I was surprised by the so many warning about conversion size_t/int in the libs sources! Ok I need to practice 64bits programming, I'm really a newbie on 64bits pitfalls, but it seems dangerous
If someone have some good pointers on 64 bits programming, post them !
How can I create a backtrace an what is it good for? (Please remember that I cannot use the Debugger in QT Creator with my application, it is not able to start the application, so doing something on the command-line would be more helpful).
dumpcpp is a Qt tool that generates a C++ namespace for a type library.
The problem i am facing is that i have commercial Qt4.3 version, integrated with visual studio 2005. So i can't use visual studio 2008 just for attaining my one goal. That is why i am looking for some tool which can produce a C++ namespace from 2008 dll, usable in 2005.
Though i really doubt, if its possible. :(
Thank you folks for advices! I've followed both: I rebuilt it with explicit sqllite option and took clean sources. One more option is that I built in at another PC :) Actually I don't know what is the reason of that three forced Assistant to work but it seems that it works fine now.
promotion (the easy one, you won't see any graphical difference between your custom widget and the parent one, cause it "promises" you only the fact that setupUi method will create a widget of your custom type, and not the original one). In this case, just right-click on your widget, promote it, give your .h header file and the type of your custom widget.
