Just in case someone would like to compare with others. Here are 3 "hello world"s #1 - HelloWorld using its builtin HTML-like markup language: hello1. d -------------------------------------------- module samples.hello1; // HTML Hello World. import harmonia.ui.application; import harmonia.ui.window; import harmonia.html.view; // HTML behavior can be attached to any container // This time to the window. alias HtmlPanelT!(Window) HtmlWindow; void HelloWorldStart() { HtmlWindow w = new HtmlWindow; w.html = "<HTML back-color='edit info' text-align=center vertical-align=middle>Hello World!</HTML>"; w.state = Window.STATE.SHOWN; } static this() { Application.onStart = &HelloWorldStart; } EOF: -------------------------------- #2: Pure HelloWorld hello2.d -------------------------------------------- module samples.hello1; // Hello World with custom draw. import harmonia.ui.application; import harmonia.ui.window; import harmonia.gx.graphics; class MyWindow:Window { this() { windowCaption = "Hello2"; } const wchar[] message = "Hello World!"; override void draw(Graphics g) { // client rect is a rect with origin (0,0) rect clientRc = rect(this.place.dim); // fill background by gradient colors g.fillRect(clientRc, 0x8ce8ff, 0x8ce8ff, 0x0066cc, 0x0066cc); // create font or get it from font cache // and select it into the Graphics g.font = Font.create("Century Gothic", 36); // textColor g.textColor = 0x003399; // draw chars g.drawChars(message, clientRc, Graphics.DRAW.CENTER | Graphics.DRAW.MIDDLE); } } static this() { Application.onStart = function void() { // create MyWindow and show it (new MyWindow()).state = Window.STATE.SHOWN; }; } EOF: ------------------------------------------------ #3.

I like harmonia( can't really use it because there's no docs ) but i'm sure it's the most portable toolkit there.

> I like harmonia( can't really use it because there's no docs ) but i'm sure it's the most portable toolkit there. Well let's start together then. I've added following page into HarmoniaWiki: http://www.terrainformatica.com/wiki/pmwiki.php/Harmonia/Documentation Feel free to add there names of chapters you would like to see there. Andrew.
