Does anyone have examples of GTK code in D?

Sorry, but my background doesn't include much C, so the standard examples don't help me much.

What I'd like to do is put some text on a window, put a button with a pixmap on the window, and then change the color of the window whenever the button is pushed.

(This is for a game on learning note names.  If I finish it, I'll gladly post it as a sample, but even though the Python original is working, I can't figure out how to get started on the D gtk interface.  Thanks to teqDruid<me@teqdruid.com> for the files, so I can see that it OUGHT to be possible.)

Have you tried DUI (http://dui.sourceforge.net/)? It's a wrapper based on GTK+.

Might provide some hints:

From what I seen of it (I haven't looked into it deeply) it's dependent on more than just GTK+.  For me this would be bad, because I want to port to multiple platforms:
Linux-86, Linux-PPC, MacOSX, and MSWind95.
I think I can get basic GTK on all of those (I'm not sure about MSWind95), but anything more...

That said, no, I haven't tried it.  It ought, if nothing else, to be a good source of examples.

I suggest you learn GTK C before you learn GTK D.

Anyway, D GTK bindings are here... http://svn.dsource.org/svn/projects/bindings/trunk/

You may have a point, but that removes a lot of the reason for using D on this project.  O, well.

there are no other dependencies.
things like zlib1.dll are required by gtk it self.
other like libpng are optional.

the plain gtk D bindings migth be better for you but anyway
here is the DUI code to do it, the functions names are similar
setBorderWidth was gtk_set_border_width.
/**
 * Modified HelloWorld
 */
class HelloWorld : MainWindow
{
	
	private import std.stdio;

	this()
	{
		super("DUI Hello World");
		setBorderWidth(100);
		Button button = new PixbufButton(logo, &buttonAction);
		
		add(button);

		show();
	}

	// the functionalities of this should be integrated into
	// the main class Button	
	class PixbufButton : Button
	{
		this(char** xpm, void delegate(Button) dlg)
		{
			super("", dlg);
			Pixbuf pixbuf = new Pixbuf(logo);
			removeAll();
			add(new Image(pixbuf));
			setBorderWidth(0);
			setRelief(ReliefStyle.NONE);
		}
	}
	
	ubyte cLevel;
	void buttonAction(Button button)
	{
		printf("Hello there\n");
		cLevel+=80;
		modifyBG(
		  StateType.NORMAL,
		  new Color(cLevel,cast(ubyte)0,cast(ubyte)(255-cLevel))
		);
	}
}

void main(char[][] args)
{
	DUI dui = DUI.dui(args);
	new HelloWorld();
	dui.go();
}


/* XPM */

"32 42 6 1",

You don't even need to learn GTK. Get GLADE, it's a wysiwyg Gtk gui builder that will output a XML file. Then use the libglade binding (it's on dsource) and with 3 or 4 lines of D code, you can dynamically load the XML file etc... sooo easy.

GLADE RULEZ !

Interesting... I'm actually in the middle of setting up something similar for Win32 (in the middle means I just finished the (fairly minimalistic) XML parser).  Its part of a library I've been working on for one reason and one reason only: I could use it myself, and I wanted to test a couple of ideas.  One of them being this "store a GUI as an XML file" thing.

What does the GLADE XML look like?  My CGX (Casal GUI XML) files look something like this:
# <AppFrame caption="Test Window" controls="min,max" icon="file:icon.bmp" width="640" height="480" position="center">
#     <BorderLayout north="*,20%" south="*,20%" east="20%,*" west="20%,*">
#         <Label position="north" caption="Hello World, from Casual Win32!" name="top text"/>
#         <Panel position="west">
#             <ColumnLayout>
#                 <Button caption="Text 1" action="appframe text 1" />
#                 <Button caption="Text 2" action="appframe text 2" />
#             </ColumnLayout>
#         </Panel>
#         <Label position="center" caption="Just a simple demonstration application that does extremely little.  Play around with the buttons a bit, and check out the file 'text.cgx' where this entire GUI is defined!  Amazing, huh?" />
#         <Button position="east" caption="Press me!" action="appframe pressme" name="pressme button" />
#         <Panel position="south">
#             <Button caption="Minimize" action="appframe min" name="min/max button" />
#             <Button caption="Exit" action="app exit" />
#         </Panel>
#     </BorderLayout>
# </AppFrame>

I have a singleton called CgxManager (module casual.cgx.manager) which can be notified of new classes implementing interface ICgxWidget (module casual.cgx.widget) and thus expand on what can be put in the CGX file. But... this thing is going to be forever in coming, so I should hush about it.

win32 ? I didn't know people were still using this sh**... anyway, you can use libglade under win32 as there's GTK2 dlls for win32...
