[SOLVED] How to use connect in a shared library?

sierdzio

Is the slot declared as a slot? Does live in a class that inherits from QObject, and is there Q_OBJECT macro there in the header?

I have added markdown tags for code sections of post.
Please checkout the "markdown tags" at the end of thread.

Yes :

class LIBRARY1SHARED_EXPORT Library1
{
    Q_OBJECT
public:
    Library1();
    void Inint_Lib();
private slots:
    void Capture_Received_Data();

I used code format but seems not working!

@Mohammadsm
You need to use three of ` at start and end of your code block.Check the end of the whole thread here. There is a short explanation.
Some keyboards do not support ` as a key. In this case you can go to the end of the thread and copy the three characters required and paste them where needed.

No need for that. You can just make a code block by having a separate paragraph that has a four-space intendation

Your class does not inherit from QObject. Try this:

class LIBRARY1SHARED_EXPORT Library1 : public QObject

Then remeber to rebuild and relink the library, and your project that uses it.

@sierdzio Indeed the back ticks are not mandatory, however it gives the forum engine a good hint of what is following

@sierdzio
It worked by adding ": public QObject"
Thank you, very much

in the cheat sheet you can actually find:
Blocks of code are either fenced by lines with three back-ticks ```, or are indented with four spaces. I recommend only using the fenced code blocks -- they're easier and only they support syntax highlighting.

The question is what is the syntax highlighting now?
