Accessing "log-class" from other classes

[darksaga]

Hi guys,

if my class hierarchy would look like this:

_                           mainWindow
                                |
                  -------------------------
                  |             |         |
                class_A      class_B   logClass
                  |             |
                class_C      class_D
                  |
                class_E

_                           mainWindow
                                |
                  -------------------------
                  |             |         |
                class_A      class_B   logClass
                  |             |
                class_C      class_D
                  |
                class_E

To copy to clipboard, switch view to plain text mode 

and my logClass has the following slot:

public slots:
		void setLog(QString &str, int &logType);

public slots:
		void setLog(QString &str, int &logType);

To copy to clipboard, switch view to plain text mode 

what is the best way to connect a signal from within class_E or class_D with my logClass???

I hope you get what I have problems with....
