I've built library with 2.066.1 and master
Despite resources is not copied by dub it works fine.
Fixed C-style arrays and sent PR https://github.com/buggins/dlangui/pull/24

DlangUI is designed to be easy embeddable.
You will need to implement Window and Platform to wrap key and mouse events,
and call drawing of widgets above OpenGL scene.

Is there any good game framework for D?
I can try to make a wrapper to use dlangui widgets inside such framework.

Merged! Thank you!

This prompted me to finally solve this issue. For future reference:

I've created pull request for dlib with added support of transparency in indexed color PNGs.
Issue with non-transparent buttons will be fixed after pull request integration.

Is there any chance of supporting user-supplied rendering primitives? If this were a library that lived above some application supplied rendering primitives, then I could make use of this.

What rendering primitives are required? Pixel buffers? Any vertex processing happening? Text I imagine is a tough one...

Not sure what do you mean under user supplied rendering primitives.

If you want to render UI into custom rendering buffer, you can define DrawBuf based class.
It requires following drawing primitives to be implemented:
- fill whole buffer with solid color
- fill rectangle with solid color
- draw font glyph (8 bit alpha image)
- draw 32 bit RGBA image

If your app is OpenGL based, there is already GLDrawBuf wich draws into opengl.

As well, UI can be drawn in ColorDrawBuf - 32bit RGBA buffer - and then transferred to your surface.

For embedding into third party framework, dlangui needs external mouse and key events translated into its own events.

Issue #22 is implemented.
Now path in FileDialog is shown as segments like on Win 7 - clicking on segment moves to directory, clicking on arrow after segments opens popup with subdirs inside directory. Clicking on right space of path control opens editor for path.

Sorry,

I've reproduced this issue with dub 0.9.22
It looks like some bug in DUB - it cannot find source files from referenced package.
It worked for me for newer dub - built from mainstream branch near middle of December.

Submitted fix - list of win32 files into each subproject (example1, tetris).

Now it should build ok with dub 0.9.22 on Windows
