What I find sometimes is that even if I know most things about something, I still forget things that I knew (particularly if I don't use that knowledge regularly), so reading something like this could jog your memory about things and thus improve your knowledge, even if you actually had known all of it at some point (though the odds are still that there are at least a few things in it that you never learned, even if you know a lot). - Jonathan M Davis

I can't guarantee the assert to pass, as the comment mentions it is possibly zero, which would cause failure. Also note that you're not dereferencing pxprime, I'm not sure if its intentional. Thanks, was intending to dereference. Thank you for feedback.

I received my copy this morning, earlier than I thought I would. I shall check it out over the weekend. I suspect I'll probably know a lot of the things in the book, but I'm the type who likes to watch introductory lectures because there's always something I didn't see before.

There is no plan to add new controls and I don't see any lacking ones. One can use `paint` event to draw image on button and there is `GridPanel` (with usage example `grid.d`) so I don't understand why `GridView` is needed and what is its purpose. Also I don't know what is `DataView` for. DGui is really fantastic, it is easy to use and without a big overhead. What I experienced, developers coming from other frameworks might miss a horizontal/vertical layout. This would be much easier than using a grid for this purpose. Also some more examples could boost the popularity of DGui. Especially, how can I create create my own controls? Horizontal/vertical layout can be achieved using `Control.dock` property. I will think about examples and documentation improvements. What would be really nice for business developer would be a specific Stringgrid control (like delphi/lazarus has). Here an example http://i.stack.imgur.com/FJFiN.gif Use `ListView` and `TreeView` classes. Do you accept pull requests if developers provide you new stuff for DGui? Yes, but I strongly recommend to contact me first to plan and synchronize activities to prevent useless time wasting. -- Денис В. Шеломовский Denis V. Shelomovskij
