Signals And Slots problem

[ldiamond]

I'm trying to send a vector<string> to my GUI using signals and slots. I defined a signal SetWindowList(vector<string>) in class A and a slot SetWindowList(vector<string>) in class B.

I emit SetWindowList(somevectorhere), but the slot is never executed. If I change all the vectors for int, it works perfectly.

How do I send my vector to my GUI?


Thanks!

Enable the console and see what error message you get there.

How do I do that?

Add "CONFIG+=console" to your project file, rerun qmake and build the project.

Well, I'm using VS integration I got no .pro file

I found something in the output window in debug mode:
QObject::connect: Cannot queue arguments of type 'std::vector<std::string>'

However, I had another error that I fixed by adding std:: namespace (eventho im using namespace std already)

Good. Now go and read about Q_DECLARE_METATYPE(). Or better yet, use QStringList instead of std::vector<std::string>.

QStringList looks nice, thx
