Hi!
i'm trying to get devisualization/window [1] working with some simple
opengl calls. I have created a windows with opengl context using
Window window = new Window(800, 600, "My window!"w,
WindowContextType.Opengl);
If i run
writeln("type: ", context.type);
writeln("toolkit version: ", context.toolkitVersion);
writeln("shading language version: ", context.shadingLanguageVersion);
i get correct information
has context
type: Opengl
toolkit version: 4.5.0 NVIDIA 347.09
shading language version: 4.50 NVIDIA
First i tried to simply call glClearColor(1,0,0,1);, this crashes the
application (Program exited with code -1073741819)
I checked the function pointer with if(cast(void*)glClearColor !is
null){...} and well ... it's a nullpointer the first two frames. Then i
checked for nullpointer and called glClearColor(...) and glClear(...) ->
no crash but the window was just frozen.
Does anyone use Devisualization/window on Windows with success?
Fyi, if i dont do any opengl calls the window seems to work, i can close
it normally, it's completely white.
My example sourcecode can be found here:

1) You need to check that the context has been created
window.addOnDraw((Windowable window2) {
IContext context = window.context;
if (context !is null) {
2) The context needs to be activated
bool hitContext;
while(true) {
import core.thread : Thread;
import core.time : dur;
Window.messageLoopIteration();
IContext context = window.context;
if (window.hasBeenClosed)
break;
else if (context !is null) {
if (!hitContext) {
context.activate;
// init opengl stuff
hitContext = true;
}
window.onDraw;
}
Thread.sleep(dur!"msecs"(25));
}
2 handles 1 already, so you don't need to add 1 only 2.
