I finally got Ubuntu 6.06 installed and was able to get Duit to compile and all the examples compiled and worked too!

It wasn't easy as I had to change some lines here and there to get it compiling. But now I'm happy!

But, I've been trying to get Cairo running in a Gdk window. It seems there's only one html page that needs to be wrapped: http://developer.gnome.org/doc/API/2.0/gdk/gdk-Cairo-Interaction.html

The function that is the most important is

Yes, I was able to manually add the gdk_cairo_create(GdkDrawable) to all the right places and now after some hours of trying I also got cairo working inside a Duit window, in a drawingarea widget.

Here's a screenshot:

I don't remember all the stuff that I did, and it wouldn't really help, as I didn't know how to make those changes in the automatic wrapping stuff.

But basically I worked a little bit on gdk.Cairo and renamed it to gdk/GdkCairo.d and the class was also renamed GdkCairo (I'm not sure if that was necessary, but I thought it might conflict with the cairoLib.Cairo.
I wrapped the gdk_cairo_create as Cairo createFromDrawable( Drawable ); much in the same way that some other functions were wrapped in cairoLib.Cairo. And some other stuff on various files... don't remember just now.Ofcourse the names of the functions, and exact way how to wrap things should be considered by someone who knows what is possible.

Hopefully, if I have time, I'll rewrite the famous cairo-clock C/C++ examples to D.

Here's a screenshot of cairo_clock example almost working with Duit.

The cairo parts work perfectly. The only thing missing is to create a Timeout that would call a callback to update the drawingarea once every second.

I don't know how this should be done, as the Timeout.add only accepts GSourceFunc as it's callback, and I don't know how could I make a D delegate transfer into one of those?

Other "complaint" would be that Gdk.Rectangle doesn't have a constructor that would allow creating it like Rectangle(int x, int y, int width, int height). Infact, it only has a constructor for creating it from a GdkRectangle*. But I guess this is just automatically generated, and there hasn't been any need for those Gdk.Rectangles yet.

Duit is great!

You can use it for Duit demos!
As far as I'm concerned this little example is freeware, but there was no licences with the cairo examples in GTK+ and Gtkmm that this is based on. But I'm quite sure you can use it and make changes to it as much as you like.

I left some random comments into a function called onSecondsElapsed as it is not made with a good API. It should be made a lot simpler than this.

Code:

Binary for Ubuntu 6.06 (Copy the modified libDuit.a into /usr/local/lib):

There's a bug somewhere, as I tried all the C, C++ and D clocks together, and after an hour or so the D version stopped updating itself, but the C and the C++ version kept on going. But other than that it works (if you modify Duit).

The getWindow I had to make for invalidateRect was an exact copy of getDrawable:

I fixed the bug I had there. It was just an issue with the garbage collection, and my inexperience with D. A silly mistake. The Timeout object has to be member of the class, otherwise the GC will clean it up. Now it works forever (I hope).

I replaced the files with the new ones, so you can use the old links above.

I've almost got cairo working, but I don't have the version specified in the paths.d

libcairo-1.0-0.dll

Btw TestWindow.exe has an unresolved external when compiled with gtkd (and not in duit)

[Raedwulf]

Finally got it compiled

changed the reference of libcairo-1.0-0.dll to libcairo-2.dll

Cheers.
