    <p>I am required to do some 3-D application and planning to chose some library for the same. I have previous experience with Qt-qml.</p> <p>I read about OpenGl and found that it must be used basically when you one has very <em>low level drawing</em> requirements.</p> <p>I also found that there is something called QtOpenGl. </p> <p>Q1. Is QtOpenGl any less powerfull that OpenGl because it just just provide a wrapper over some OpenGl functionality? or it as good as using OpenGl with an advantage of working at higher level of abstraction ?</p> <p>Q2. I also found there is something called Qt-3D and Qt-Quick3D. I ran some sample examples and found it easy to use because of my previous experience with qml.</p> <p>Can someone share experience how <em>powerful</em> it is compared to OpenGl itself?</p> <p>My basic question is how <em>low</em> the drawing requirements should be that I should use OpenGl rather than some higher abstraction like QtOpenGl ?</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.
