Force library linking with Qt and google test

Qt library event loop problems
I'm writing a DLL that is used as a plugin by another application and would like to leverage Qt's abilities. I have all of the classes set up, compiling and running, but no signals are being emitted.

Because of special combinations, it might have only one selection left over, which has to be "confirmed" by the user, preferably by looking at all possible selections, seeing that there is only one, and then selecting this. My problem: If a us...

Modifying Qt core components/widgets, best practices?
Hello everyone, I'm trying to enhance Qt's QPrintPreviewWidget by allowing it to display page numbers (in the footer somewhere). Unfortunately, I can't quite figure out how to go about it without hacking up Qt's source. I see a great spot for this additional code (in qpaintengine_preview.cpp, in newPage() method) but that means I'm goin...
QGraphicsView/Scene - multithreading nightmare
Am I correct in thinking that the QGraphics* classes are not thread-safe? I am porting an old app to Qt and in the process attempting to make it multi-threaded too.

How can I connect the pressed() signal of 32 buttons to a single function without declaring 32 slots?
I have a widget and inside it are 32 buttons. I need to connect each button's pressed() signal to a slot in order to call a function who's parameters depend on which button I have pressed. Right now I did that by adding 32 slots in the form of on_QPushButtonName_pressed() but thats a lot of slots. I was wondering if there is another wa...

I am maintaining an application which tries to help the user get his parameters to work together, as there are many interdependencies. Now there is a default value of x for a variable Y.
