    <p>I have a simple example class. It has one data member, which is a std::vector of pointers to armadillo matrices. the constructor takes such a vector as the only argument. here's file <code>TClass.cpp</code>:</p> <pre><code>#include &lt;armadillo&gt; #include &lt;vector&gt; class TClass { private: std::vector&lt;arma::mat * &gt; mats; public: TClass(std::vector&lt;arma::mat * &gt; m_); arma::mat * GetM( int which ){ return( mats.at(which) );}; }; TClass::TClass(std::vector&lt;arma::mat * &gt; m_){ mats = m_; } </code></pre> <p>I want to construct a GTest fixture to test member function <code>GetM</code>. Here is what I have done:</p> <pre><code>#include &lt;gtest/gtest.h&gt; #include "TClass.cpp" class TClassTest : public ::testing::Test { protected: int n; int m; std::vector&lt;arma::mat * &gt; M; virtual void SetUp() { n = 3; m = 2; arma::mat M1 = arma::randu&lt;arma::mat&gt;(n,m); arma::mat M2 = arma::randu&lt;arma::mat&gt;(n,m); M.push_back( &amp;M1); M.push_back( &amp;M2); } // virtual void TearDown() {} // initiate a TClass object TClass T(M); }; // my test TEST_F(TClassTest, CanGetM1){ EXPECT_EQ( T.GetM(0), M.at(0) ); } int main(int argc, char **argv) { ::testing::InitGoogleTest(&amp;argc, argv); return RUN_ALL_TESTS(); } </code></pre> <p>I compile this with <code>g++ TClassTest.cpp -o tclass -larmadillo</code>. It tells me that <code>TClassTest.cpp:24: error: ‘M’ is not a type</code>. I dont' understand why I cannot construct the TClass object in the fixture definition?</p>

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.
