de_window 0.1.0

Devisualization Window Toolkit

Window creational toolkit, cross platform. Written in D.
Depends on Derelict-GL3 for Opengl support.

Features

• Create, Destroy, On draw
• Move, Resize
• Key down/up with modifiers
• Mouse left/right/middle down/up
• Window Icon, Text
• OpenGL (both legacy and 3+) creation (Windows, X11, OSX (Cocoa))
• 2D image buffer drawing context

Example

Custom event loop

import devisualization.window.window;
import std.stdio;

void main() {
	Window window = new Window(800, 600, "My window!"w);
	window.show();

	window.addOnDraw((Windowable window2) {
		writeln("drawing");
  });

  while(true) {
    import core.thread : Thread;
    import core.time : dur;
    Window.messageLoopIteration();

    if (window.hasBeenClosed)
        break;
    else
        window.onDraw();
    //Thread.sleep(dur!"msecs"(25));
  }
}

Thread sleep is optional, as messageLoopIteration is blocking but may not wait for a message.
However it should be one draw per x time units. For most efficient loop. During the drawing, check if you have a valid context. OnDraw may occur while there is no valid context.

TODO

• Confirm prevent close works on Windows and X11
• Context creation (Direct3D on Windows)
• On window redisplay(undo of minimise)/maximise/minimise
• Confirm Buffer2d context works on Posix

X11 based window manager weird behaviours:

• Make sure icons work on Posix
• Make sure full screen works correctly on Posix (tempermental on XFCE)
