I've added first DlangUI tutorial on DlangUI Wiki:

https://github.com/buggins/dlangui/wiki/Getting-Started

It covers creation of simple DlangUI helloworld project, and then illustrates layouts, standard controls, DML, and signals.

Source code for all examples is available on GitHub

https://github.com/buggins/dlangui-examples

I'm looking forward for ideas for next tutorials.

Great work!!

On windows works fine.

Problem with freetype? or Derelict? What's wrong?

google on FT_Gzip_Uncompress show smth about 2.5-2.6 of freetype. May be, this is just new function. In wheezy thereis 2.4 freetype. (

But glxgears works fine, glxinfo show direct rendering: yes.
BTW, why openGL for forms ?
in wiki:

"Fallback to pure Win32 API / SDL / XCB when OpenGL is not available (e.g. opengl dynamic library cannot be loaded)"
Why no fallback?

BTW, if I remove USE_OPENGL works fine :)

Project Update:

FontConfig support is added for Linux builds
Examples available on https://github.com/buggins/dlangui-examples
Getting Started tutorial: https://github.com/buggins/dlangui/wiki/Getting-Started
Some bugs fixed

Is it's possible to use some native frontend with dlangui instead of drawing all controls with OpenGL? I really dislike how all OpenGL toolkit looks like.

Is it's possible to make dlangui fully compatibility with QML to be able easy migrate visual components from Qt solution to dlangui?

Maybe tutorial on Menus, tabs, list view, and a little excell app

OpenGL is just hardware acceleration for drawing. Resulting picture is the same for both OpenGL and software rendering.

DlangUI will never use native controls. It draws all widgets itself.
But look and feel can be changed by providing custom theme.
You can create theme (set of .xml and .png files) to get DlangUI app looking exactly like native one.

No. It's not planned at least for now.

I started to work on Spreadsheet (Excel like app) example
    dub run dlangui:spreadsheet
    (dlangui/examples/spreadsheet)

Its implementation is in the very beginning. Worksheet split view support development is in progress.

In general I don't care about that sort of thing, but there is one exception: the main application menu. Unity and Aqua (OS X) both end up feeling odd if you don't use the system one.
