Body
You don't need to use <code>printf</code> wherever in the code, but you will need to call <code>TestClass::Log</code> with extra parameters <code>__FILE__</code> and <code>__func__</code>. Don't threat however, you can create a macro for that so you don't have to write down the extra parameters on each call: <pre><code>#define TEST_CLASS_LOG(testClassInstance,status) \ testClassInstance.Log((int)status, __FILE__, __func__); </code></pre> and instead of calling <pre><code>tt.Log((int)1); </code></pre> you would call <pre><code>TEST_CLASS_LOG(tt,1); </code></pre> You'd need to change the <code>Log</code> signature to account for the extra parameters of course: <pre><code>void Log(int status, const char* fileName, const char* functionName); </code></pre> Also, I see <code>Log</code> isn't accessing any class members, so you can make it even easier and make it <code>static</code>: <pre><code>class TestClass { static void Log(int status); }; void TestClass::Log(int status, const char* file, const char* func) { printf("%s %s %i", file, func, status); } #define TEST_CLASS_LOG(status) \ TestClass::Log((int)status, __FILE__, __func__); </code></pre> So, if you do it like this, you'd only need to call: <pre><code>TEST_CLASS_LOG(1); </code></pre> Unfortunately there's no way to do this automatically, without modifying your code, as macros expand at runtime. What your compiler sees now is: <pre><code>void TestClass::Log(int status) { printf("%s %s %i","Test.cpp","Log", status); } </code></pre> that is why you need the file name and function name passed as parameters.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
