Hello!

I would like to announce my project, DlangUI library - 
cross-platform GUI for D.
https://github.com/buggins/dlangui
License: Boost License 1.0

Native library written in D (not a wrapper to other GUI library) 
- easy to extend.
As a backend, uses SDL2 on any platform, Win32 API on Windows, 
XCB on Linux. Other backends can be added easy.
Tested on Windows and Linux.
Supports hardware acceleration - drawing using OpenGL when built 
with version=USE_OPENGL.
Unicode support.
Internationalization support.
Uses Win32 API fonts on Windows, and FreeType on other platforms.
Same look and feel can be achieved on all platforms.
Flexible look and feel - themes and styles.
API is a bit similar to Android UI.
Flexible layout, support of different screen DPI, scaling.
Uses two phase layout like in Android.
Supports drawable resources in .png and .jpeg, nine-patch pngs 
and state drawables like in Android.
Single threaded. Use other threads for performing slow tasks.
Mouse oriented.

Actually, it's a port (with major redesign) of my library used 
for cross-platform version of my application CoolReader from C++.


State of project: alpha. But, already can be used for simple 2D 
games and simple GUI apps.
I'm keeping in mind a goal to write D language IDE based on 
dlangui. :)
Adding support of 3D graphics is planned.


Currently implemented widgets:

TextWidget - simple static text (TODO: implement multiline 
formatting)
ImageWidget - static image
Button - simple button with text label
ImageButton - image only button
TextImageButton - button with icon and label
CheckBox - check button with label
RadioButton - radio button with label
EditLine - single line edit
EditBox - multiline editor
VSpacer - vertical spacer - just an empty widget with 
layoutHeight == FILL_PARENT, to fill vertical space in layouts
HSpacer - horizontal spacer - just an empty widget with 
layoutWidth == FILL_PARENT, to fill horizontal space in layouts
ScrollBar - scroll bar
TabControl - tabs widget, allows to select one of tabs
TabHost - container for pages controlled by TabControl
TabWidget - combination of TabControl and TabHost

Layouts - Similar to layouts in Android

LinearLayout - layout children horizontally or vertically 
depending on orientation
VerticalLayout - just a LinearLayout with vertical orientation
HorizontalLayout - just a LinearLayout with vertical orientation
FrameLayout - all children occupy the same place; usually onle 
one of them is visible
TableLayout - children are aligned into rows and columns of table

List Views - similar to lists in Android UI API.
ListWidget - layout dynamic items horizontally or vertically (one 
in row/column) with automatic scrollbar; can reuse widgets for 
similar items
ListAdapter - interface to provide data and widgets for ListWidget
WidgetListAdapter - simple implementation of ListAdapter 
interface - just a list of widgets (one per list item) to show


Sample project, example1 contains demo code for most of dlangui 
API.

Try it using DUB:

     git clone https://github.com/buggins/dlangui.git
     cd dlangui
     dub run dlangui:example1

Fonts note: on Linux, several .TTFs are loaded from hardcoded 
paths (suitable for Ubuntu).
TODO: add fontconfig support to access all available system fonts.

Helloworld:

// main.d
import dlangui.all;
mixin DLANGUI_ENTRY_POINT;

/// entry point for dlangui based application
extern (C) int UIAppMain(string[] args) {
     // resource directory search paths
     string[] resourceDirs = [
         appendPath(exePath, "../res/"),   // for Visual D and DUB 
builds
         appendPath(exePath, "../../res/") // for Mono-D builds
     ];

     // setup resource directories - will use only existing 
directories
     Platform.instance.resourceDirs = resourceDirs;
     // select translation file - for english language
     Platform.instance.uiLanguage = "en";
     // load theme from file "theme_default.xml"
     Platform.instance.uiTheme = "theme_default";

     // create window
     Window window = Platform.instance.createWindow("My Window", 
null);
     // create some widget to show in window
     window.mainWidget = (new Button()).text("Hello 
world"d).textColor(0xFF0000); // red text
     // show window
     window.show();
     // run message loop
     return Platform.instance.enterMessageLoop();
}

DDOC generated documentation can be found there: 
https://github.com/buggins/dlangui/tree/master/docs
For more info see readme and example1 code.

I would be glad to see any feedback.
Can this project be useful for someone? What features/widgets are 
must have for you?

Nice work. As a guy who has worked on trying to get bindings for 
existing GUI libraries to work and noting all of the issues, I 
appreciate any effort in writing native libraries. The way I see 
it, wrapper libraries might possibly be as good as using the 
libraries from the native language some day, but they will never 
be better. Native D GUI libraries hold more potential for the 
future.

Awesome.

Does this work like a conventional GUI toolkit (Gtk/Qt) or could 
I integrate this in an OpenGL game? (or would I have to integrate 
the game in it?)

Both ways available.
But I think, it's better to integrate game into it.
Otherwise you have to write more code.

:)

Not as bad as you expected.

Tried win32 release build w/o USE_SDL and USE_OPENGL version
constants (using win32 API only).

helloworld.exe executable size 813k, memory 6.6M on start
example1.exe executable size 847k, memory 6.7M on start
As I see, memory consumption grows while app is working.
Probably, extra GC allocations, or some resources leaking.

Can be reduced a bit, e.g. by moving to libpng from libfreeimage.

Main limitation here - app needs buffer for 32bit RGBA bitmap
buffer to draw into.

You might want to store them in the "gh-pages" branch

where you can host your pages (as versioning them will soon be 
very impractical to anyone cloning your repository).
Also, you may be interested by DDOX (dub --build=ddox).

Thanks a million! Please keep it up. Finally we get our own GUI. 
I've been dreaming of this for years. As has been mentioned 
before, bindings are only as good as the UI they bind to. With a 
native UI you can use the full power of the language itself. 
Talking about templates and stuff ...

Are you planning to make it C(++) compatible so that non-D-people 
could use it too?

Hi Vadim,

I am evaluating GUIs for a project I have in mind and the DLangUI looks 
interesting...

First problem: you need to add gl3n to the git clone list for developing 
under Visual-D.

I am having problems running (debugging) the example1 program. When loading 
the resources it gets to tab_up_background.9.png (line 579 in file 
resources.d) and then fails with an exception:

"Unhandled exception at 0x0044f932 in example1.exe: 0xC0000005: Access 
violation reading location 0x00000000."

Do you have any clues as to what the problem could be?

Regards,
-=mike=-

I didn't compile this, so take it with a grain of salt.

Access violation reading 0x00000000 is a null pointer 
dereference. Looking at the source:

_drawbuf = loadImage(_filename);

I'm making a wild guess that loadImage returns a null if it can't 
find the file. Dereferencing thus throws. You probably lack the 
image or it's in the wrong place.

 I didn't compile this, so take it with a grain of salt.

 Access violation reading 0x00000000 is a null pointer 
 dereference. Looking at the source:

 _drawbuf = loadImage(_filename);
 if (_filename.endsWith(".9.png"))
     _drawbuf.detectNinePatch();

 I'm making a wild guess that loadImage returns a null if it 
 can't find the file. Dereferencing thus throws. You probably

Hi Casper,

I checked the sub-directory the loading refers to and all the 
pngs seems to be there.

I managed to get the files from github just fine, but dub says it 
is unable to copy a libpng file to the example case. I'm not sure 
what is wrong, the instructions are three lines of code after 
all. =/

git clone https://github.com/buggins/dlangui.git
cd dlangui
dub run dlangui:example1

libpng is not needed anymore.

These three lines worked ok for me some time ago.
But now I'm facing with another problem while trying dub build:

Building dlangui:example1 configuration "application", build type 
debug.
Compiling...
Error: conflicting Ddoc and obj generation options

Does anyone know how to fix it?

Fixed. I've removed gl3n and libpng references from project.

Search log file examples/example1/ui.log for lines like
2014-06-11 13:21:11.070 D  DrawableCache: adding path 
C:\projects\d\dlangui\examples\example1\Debug\..\..\..\res\ to

to resource dir list.
2014-06-11 13:21:11.070 D  DrawableCache: path 
C:\projects\d\dlangui\examples\example1\Debug\..\..\..\..\res\ 
does not exist.
....
2014-06-11 13:21:11.086 D  DrawableCache: path 
C:\projects\d\dlangui\examples\example1\Debug\..\..\res\mdpi\ 
does not exist.

In examples/example1/main.d several directories are added as 
resource path
candidates

     // resource directory search paths
     string[] resourceDirs = [
         appendPath(exePath, "../../../res/"),   // for Visual D 
and DUB builds
         appendPath(exePath, "../../../res/mdpi/"),   // for 
Visual D and DUB builds
         appendPath(exePath, "../../../../res/"),// for Mono-D 
builds
         appendPath(exePath, "../../../../res/mdpi/"),// for 
Mono-D builds
		appendPath(exePath, "res/"), // when res dir is located at the 
same directory as executable
		appendPath(exePath, "../res/"), // when res dir is located at 
project directory
		appendPath(exePath, "../../res/"), // when res dir is located 
at the same directory as executable
		appendPath(exePath, "res/mdpi/"), // when res dir is located at 
the same directory as executable
		appendPath(exePath, "../res/mdpi/"), // when res dir is located 
at project directory
		appendPath(exePath, "../../res/mdpi/") // when res dir is 
located at the same directory as executable
	];

If your executable is not located in examples/example1/Debug, 
probably you add path to your directory to list of resource dirs.

Another possible reason - FreeImage.dll is found.
Try to copy FreeImage.dll from lib directory to 
examples/example1/Debug

Never tried it on mac.
I believe, if OpenGL context cannot be created, DlangUI SDL 
backend should switch to bare SDL (sw renderer).
I would rather expect that app crashes on missing fonts.
Linux (and mac) font paths are hardcoded. Where are .ttf files 
located on macos? Fast and dirty fix is possible - add paths for 
a few mac fonts.
Could you please share startup logs?

As well, you can try to build w/o OpenGL - clone repository and 
remove USE_OPENGL version from dub.json

 What are good/standard Sans Serif and Monotype fonts on Macs?


I think the system defaults are:
Helvetica Neue (in OS X 10.10), Lucida Grande (in 10.9 and 
previous), Menlo Regular

 This is looks fantastic. I tried the demo but I get an 
 error:
 SDL_GL_CreateContext failed: Failed creating OpenGL context

 Running Mac OS 10.10.2 on 2011 Macbook Pro


 Never tried it on mac.
 I believe, if OpenGL context cannot be created, DlangUI SDL 
 backend should switch to bare SDL (sw renderer).
 I would rather expect that app crashes on missing fonts.
 Linux (and mac) font paths are hardcoded. Where are .ttf 
 files located on macos? Fast and dirty fix is possible - add 
 paths for a few mac fonts.
 Could you please share startup logs?

 As well, you can try to build w/o OpenGL - clone repository 
 and remove USE_OPENGL version from dub.json


 All the projects in examples/ crash on OS X in functions 
 relating to text AFAICS.

 Font locations on OS X:

 Could you please share file list of /Library/Fonts/ and

All working for me now.

A few points:
As I mentioned about dlangide, the font scaling is nasty.
The Window menu name overflows and is clipped.
Are the draggable dividers in the Buttons tab supposed to be able 
to move? They don't seem to do anything.

Resizers in example1 are just for testing of mouse cursor change 
- not fully implemented.
You can see working resizers in dlangide so far.

I've added Gamma setting for font rendering. Now text looks 
acceptable.
In DlangIDE v0.1.4, I'm using
         FontManager.fontGamma = 0.8;
	FontManager.hintingMode = HintingMode.AutoHint;
(as well, for Windows versions, USE_FREETYPE is set - but it 
falls back to win32 font rendering if no freetype.dll found)
As for me, now font rendering look good with such settings.
Latest features implemented:
* Text cursor blinking
* Update of actions state in UI (now working better for toolbars, 
has some bugs for menu items, will be fixed soon)

Now DlangIDE allows to open DUB project, edit it, build and run, 
clean, rebuild, upgrade dependencies (using DUB).

I hope it will become usable in a few weeks.

That works OK.

The text is all horrible looking. This is probably due to (lack 
of) scaling support for high-res screens (retina).

The main menu's open ok, but a second click to close them does 
nothing. Clicking elsewhere does close them though.

Not using the native OS X menu system leads to a rather grating 
experience. You'll get a similar story from Ubuntu Unity users.

Is graphics scaled too? If so, it's due to scaling.
Otherwise possible it's due to bad implementation of subpixel 
antialiasing (aka ClearType).
I've submitted fix to disable subpixel antialiasing.

It's known problem.

But it requires some work to update system menu.
I don't have mac to do it anyway.
Probably, someone will implement it later.

 That works OK.

 The text is all horrible looking. This is probably due to 
 (lack of) scaling support for high-res screens (retina).


 Is graphics scaled too? If so, it's due to scaling.
 Otherwise possible it's due to bad implementation of subpixel

I see no additional blur comparing with other platforms.
It's bad font rendering. Trying to improve.

P.S: DlangIDE is now able to open DUB based projects, build and 
run them, edit files.
Good sample project is dlangide/workspaces/tetris :)

 From what I can tell, it seems to be that it's using X11 for 
rendering, which I think doesn't support high DPI properly when 
using a Retina screen, making it appear very blurry.

I don't know what makes dlangui (dlangide?) use X11 though.

DlangUI just uses libsdl.

The only possible reason of blurring is SDL2 implementation on 
MAC.

Which actually is kind of sad for those who is integrating with 
dub. We also have to support two formats.

An ideal solution would to have a libdub on code.dlang.org. The 
second best solution would be to stick to either json or sdl (in 
case of picking sdl make a migrate script from json to sdl).

Look & feel can be customized with themes.
Current default theme is near to look&feel of MS Visual Studio 
2013.
I hope by changes of theme you can make UI not so ugly.

So far, there is no much feedback from users.

Hello,

Works for me - I cannot reproduce the problem.
It looks like -J parameters are not passed properly to compiler.
For embedding of resources into executable, -J include paths must 
be set for directories views, views/res, views/res/mdpi, 
views/res/i18.
When I'm running dub with -v switch, I see
-Jviews -Jviews/res -Jviews/res/mdpi -Jviews/res/i18 in DMD 
command line

Probably, it depends on DUB version.
My one is 0.9.22 Sep 16 2014 (downloaded from 
code.dlang.org/downloads)

Ok. Added following notice to README (you can see it on project 
main page on GitHub)

Important notice
================

If build of your app is failed due to dlangui or its 
dependencies, probably you have not upgraded dependencies.

Try following:

	dub upgrade --force-remove
	dub build --force

As well, sometimes removing of dub.json.selections can help.

 Hello!

 I would like to announce my project, DlangUI library - 
 cross-platform GUI for D.
 https://github.com/buggins/dlangui
 License: Boost License 1.0

 Native library written in D (not a wrapper to other GUI 
 library) - easy to extend.
 As a backend, uses SDL2 on any platform, Win32 API on Windows, 
 XCB on Linux. Other backends can be added easy.
 Tested on Windows and Linux.
 Supports hardware acceleration - drawing using OpenGL when 
 built with version=USE_OPENGL.
 Unicode support.
 Internationalization support.
 Uses Win32 API fonts on Windows, and FreeType on other 
 platforms.
 Same look and feel can be achieved on all platforms.
 Flexible look and feel - themes and styles.
 API is a bit similar to Android UI.
 Flexible layout, support of different screen DPI, scaling.
 Uses two phase layout like in Android.
 Supports drawable resources in .png and .jpeg, nine-patch pngs 
 and state drawables like in Android.
 Single threaded. Use other threads for performing slow tasks.
 Mouse oriented.

 Actually, it's a port (with major redesign) of my library used 
 for cross-platform version of my application CoolReader from 
 C++.


 State of project: alpha. But, already can be used for simple 2D 
 games and simple GUI apps.
 I'm keeping in mind a goal to write D language IDE based on 
 dlangui. :)
 Adding support of 3D graphics is planned.


 Currently implemented widgets:

 TextWidget - simple static text (TODO: implement multiline 
 formatting)
 ImageWidget - static image
 Button - simple button with text label
 ImageButton - image only button
 TextImageButton - button with icon and label
 CheckBox - check button with label
 RadioButton - radio button with label
 EditLine - single line edit
 EditBox - multiline editor
 VSpacer - vertical spacer - just an empty widget with 
 layoutHeight == FILL_PARENT, to fill vertical space in layouts
 HSpacer - horizontal spacer - just an empty widget with 
 layoutWidth == FILL_PARENT, to fill horizontal space in layouts
 ScrollBar - scroll bar
 TabControl - tabs widget, allows to select one of tabs
 TabHost - container for pages controlled by TabControl
 TabWidget - combination of TabControl and TabHost

 Layouts - Similar to layouts in Android

 LinearLayout - layout children horizontally or vertically 
 depending on orientation
 VerticalLayout - just a LinearLayout with vertical orientation
 HorizontalLayout - just a LinearLayout with vertical orientation
 FrameLayout - all children occupy the same place; usually onle 
 one of them is visible
 TableLayout - children are aligned into rows and columns of 
 table

 List Views - similar to lists in Android UI API.
 ListWidget - layout dynamic items horizontally or vertically 
 (one in row/column) with automatic scrollbar; can reuse widgets 
 for similar items
 ListAdapter - interface to provide data and widgets for 
 ListWidget
 WidgetListAdapter - simple implementation of ListAdapter 
 interface - just a list of widgets (one per list item) to show


 Sample project, example1 contains demo code for most of dlangui 
 API.

 Try it using DUB:

     git clone https://github.com/buggins/dlangui.git
     cd dlangui
     dub run dlangui:example1

 Fonts note: on Linux, several .TTFs are loaded from hardcoded 
 paths (suitable for Ubuntu).
 TODO: add fontconfig support to access all available system 
 fonts.

 Helloworld:

 // main.d
 import dlangui.all;
 mixin DLANGUI_ENTRY_POINT;

 /// entry point for dlangui based application
 extern (C) int UIAppMain(string[] args) {
     // resource directory search paths
     string[] resourceDirs = [
         appendPath(exePath, "../res/"),   // for Visual D and 
 DUB builds
         appendPath(exePath, "../../res/") // for Mono-D builds
     ];

     // setup resource directories - will use only existing 
 directories
     Platform.instance.resourceDirs = resourceDirs;
     // select translation file - for english language
     Platform.instance.uiLanguage = "en";
     // load theme from file "theme_default.xml"
     Platform.instance.uiTheme = "theme_default";

     // create window
     Window window = Platform.instance.createWindow("My Window", 
 null);
     // create some widget to show in window
     window.mainWidget = (new Button()).text("Hello 
 world"d).textColor(0xFF0000); // red text
     // show window
     window.show();
     // run message loop
     return Platform.instance.enterMessageLoop();
 }

 DDOC generated documentation can be found there: 
 https://github.com/buggins/dlangui/tree/master/docs
 For more info see readme and example1 code.

 I would be glad to see any feedback.
 Can this project be useful for someone? What features/widgets 
 are must have for you?

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.

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?

 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

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.

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.

Completely agree.

Would it be possible to add native menu for Windows? I think all 
font-related stuff is should be look native or use native 
controls. Because Apps that can't handle non standard system DPI 
looks very bad.

I see no point in implementing native Windows menus.
For high DPI, DlangUI supports loading different drawables for 
different resources, and you can specify font sizes and control 
dimensions in points or millimeters instead of pixels.
(It's similar to Android)

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


Having a GUI library fully compatible with QML request property binding 
support. We have it in DQuick, but as we use lua instead of a javascript 
VM I am not sure about how it can be possible to be compatible. 
Translating qml files in lua format will certainly not be enough, 
because their is some gliches in QML.

Sadly we don't work a lot on DQuick, but you can take a look at

 Native library written in D (not a wrapper to other GUI 
 library) - easy to extend.


OpenGLDrawable is implemented - allows to use custom OpenGL 
drawing inside DlangUI.

E.g. it's possible to draw something with OpenGL as a background, 
and put UI on top of it.

Sample: dub run dlangui:opengl


Other changes:

A lot of fixes, mainly found while DlangIDE development.

OpenGL support code refactoring and optimizations contributed by 
Viktor Makhotkin (gazer).

Dependencies now are git submodules - when developing with 
VisualD/MonoD - no more manual cloning of dependency repos is 
required.

Porting of XML/CSS visualization engine from my C++ project 
CoolReader is started.
