    <p>Will using same class name within multiple namespaces get me into trouble? I also try to remove dependency to math library. What do you think about following design.</p> <p><strong>first file</strong></p> <pre><code>#define MATH_RECTANGLE_EXISTS namespace math { class Rectangle : Object2D { public: float perimeter(); float area(); float x,y,w,h; }; } </code></pre> <p><strong>other file</strong></p> <pre><code>#define GRAPHIC_RECTANGLE_EXISTS #ifndef MATH_RECTANGLE_EXISTS //is this a good idea to remove dependency? namespace math { class Rectangle { public: float x,y,w,h; } } #endif namespace graphics { class Rectangle : math::Rectangle { public: void Draw(Canvas &amp;canvas); void Translate(float x, float y); }; } </code></pre> <p><strong>EDIT</strong></p> <p>What about this approach to remove dependency?</p> <p>** 1st file**</p> <pre><code>namespace common { class Rectangle { float x,y,w,h; }; } </code></pre> <p><strong>math lib file</strong></p> <pre><code>#define MATH_RECTANGLE_EXISTS namespace math { class Rectangle : public common::Rectangle, public Object2D { public: float perimeter(); float area(); }; } </code></pre> <p><strong>graphic file</strong></p> <pre><code>#define GRAPHIC_RECTANGLE_EXISTS namespace graphics { #ifndef MATH_RECTANGLE_EXISTS class Rectangle : public math::Rectangle { #else class Rectangle : public common::Rectangle { #endif public: void Draw(Canvas &amp;canvas); void Translate(float x, float y); }; } </code></pre> <p>Thanks in advance.</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.
