Another signal and slot question

[fnmblot]

Is there a way to connect a signal of a MDISubWindow to a slot in a main window? I have something like this:

connect(fvui.closePBpvf, SIGNAL(clicked()), nnDBSMainWindow, SLOT(closeActiveSubWindow()));

connect(fvui.closePBpvf, SIGNAL(clicked()), nnDBSMainWindow, SLOT(closeActiveSubWindow()));

To copy to clipboard, switch view to plain text mode 

But I keep getting the compilation error: src/nnDBSPieceViewForm.cpp:27: error: ‘nnDBSMainWindow’ was not declared in this scope

I then tried adding #include "nnDBSMainWindow.h" to the form, but now I get the compilation error: src/nnDBSPieceViewForm.cpp:28: error: expected primary-expression before ‘,’ token

Can someone help me out please? Thanks in advance!

You need to have a pointer to the object you want to connect the signal from/to. This is basic C++ - all rules that apply in regular C++ apply here as well.

As a noob, I'm not sure I understand what you mean. I thought I already had the pointers, fvui.closePBpvf's signal to nnDBSMainWindow's slot.

Where is the pointer called nnDBSMainWindow declared? Or are you mixing it up to a class name?

[wysota]

Obviously the compiler thinks you don't. I don't know your code, so I can't suggest a solution. The "nnDBSMainWindow" variable is not declared in the scope of the connect statement.

ok, I guess I am mixing the class name with pointer. How would I create a pointer from a child signal to a parent slot?
