digitalmars.D.learn - Does anyone have examples of GTK code in D?

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+.

 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.

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 */
static char** logo = [
"32 42 6 1",
"       c None",

But it is, unless there is an updated version that I don't know about, full of

I spent a week or so correcting errors in it, and then gave up because I simply
don't have that much time to devote to making it work.

The progress of DUI depends directly on how much I'm using it
and I don't have the time right now.
The latests svn on dsource (now down it seems) works perfectly on linux.
It's the best version ever (Gtk+2.6.x)!
I'll make a release as soon as possible.
John Reimer found and corrected the problems on the windows version while 
working on his dynDUI (I plan to merge both versions) so I will also look at
the making a windows release when I have time.

I just wanted to point out that I haven't yet managed to get (dynamic) 
DUI working with Gtk+2.6.x on win32; it works fine with 2.4.x.  I will 
continue to look into this.  I spent very little time trying it with 
2.6.x and all of my time on 2.4.x, so it's probably quite feasible with 
a little effort.  DynDUI, otherwise, works the same on both win32 and 
linux.

A big thank you to Ant for all his hard work with DUI.  I don't know if 
people realize how much time he put into that project, but considering 
the bug squashing he did there over the last 2 years (?), I think his 
contribution to the D language is significant. See him in Walter's 
acknowledgements list?  How do you think he got there? :-)

Concerning my DUI modification:

Using a method inspired by Kris Bells dynamic loader in Mango.ICU, 
DynDUI makes the build process a whole lot easier then before.  Just 
install your gtk+ libraries with one of the win32 gtk+ installers and 
import DUI into your project.  You need only link with the DynDUI 
library now:  all gtk symbols are loaded internally from the dll's (so's 
on linux).   Derek's build tool makes the whole process even simpler: 
just add the new DUI import directory to the \dmd\bin\sc.ini (dmd.conf 
on linux) file "-I" option, then place a dynDUI.lib in \dmd\lib 
directory (or other such that dmd knows where to look for it), and build 
a project with the following command:

build myproject.d dynDUI.lib -XDynDUI

I still have to make some updates to dynDUI to make things work 
flawlessly.  Right now, for example, opengl is not yet operational in my 
version until I convert the sources over.  Otherwise everything else 
works: sample apps were available at dsource.org, but it's down ATM. 
Also, I need to add "dynDUI.lib" to the project direcory or provide the 
build command to make it.

I'm kind of entertaining the idea of a DUI port to win32 native.   It 
looks like it would be a lot of work, but may be a great exercise. 
Meanwhile, I hoping to also help Sean Liu shape up DWT for a usable 
release.  We'll see where we go.  I may be biting off a little too much. :-)

I take it you're the one developing it?

Perhaps I could help get it up to date somehow.
It may not be worth my time to work on it just for me,
especially since I have never seen it working right and would likely run into
questions that I don't have the answers to,
but if I am working in cooperation with the developer to get it working right
for everyone,
that would be at least a worth while endeavor.

SVN on dsource is back up, for linux, go there and grab dool and DUI.
(I hope the Makefiles are up to date, can't remember).
The Makefiles will need small customizations.

PS
for a wonderfull IDE experience on linux grab the leds preview release

(setting up a project is still only for those who can follow instructions:
http://leds.sourceforge.net/projTarget.html

if the project is not properly setup intellisence will not find the

I never tried it but you can probably set new d build tools on the

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

Anyway, D GTK bindings are here...

You may have a point, but that removes a lot of the reason for

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:

icon="file:icon.bmp" width="640" height="480" position="center">


Win32!" name="top text"/>







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?" />

pressme" name="pressme button" />


name="min/max button" />





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.

 XML file" thing.

 What does the GLADE XML look like?  My CGX (Casal GUI XML) files look
 something like this:

 icon="file:icon.bmp" width="640" height="480" position="center">


 Win32!" name="top text"/>







 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?" />

 pressme" name="pressme button" />


 name="min/max button" />





 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.

I'm curious... How far along are you on this, and are you planning to release
it?

Sadly I'm not a whole lot farther along, mostly because of a lack of 
time to devote to it.  Once it is somewhere near really usable I will 
probably ask to put it on DSource or otherwise share it.  I've got a few 
other ideas I'm toying with in this lib, such as the Command singleton. 
  Commands can be "bound to"/"unbound from" widgets, via "command 
slots".  For instance, the Button widget supports the "on click" slot. 
So in code you would do something like this: (note this is prototype code)




















Note that if a given Command does not "exist" (meaning it is an invalid 
key into the Command singleton's assoc-array-like interface) then it 
simply isn't ran.  In other words, it is not an error to have a "null" 
command.  It is just a command that doesn't do anything.















Although, to be honest, I've been looking at the Harmonia library and 
wondering of a loading-from-xml approach could be worked into it.  I 
like Harmonia overall, and may well be using it myself in the future.

Looks promising.
I also fully understand the time constraints issue,
and wish you the best of luck in finding the time to accomplish your goals on
the project.

If you get it to a stage where you would like an outside tester, let me know.
I'll see what I can find time to do.
