NEWT : dialog frame and transparent frame

Hello (again)

I am trying to make somekind of tooltip effect (using NEWT).

So far I made a new frame undecorated over the main frame and display what I want in it.
But I still have 2 problems :

- first it has it's own button in the system toolbar which I don't want, it should be a child of the main frame. like a dialog frame, they don't have any system bar button associated either.

- second, the frame is opaque, I am displaying a small icon (a warning/alert/ok icon) but it doesn't make very nice since the background of my tooltip frame is not transparent. The doc says it's possible (http://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/com/jogamp/newt/Window.html)
but I haven't found any method to achieve this.
Maybe it's my system too, i don't know ?it's XFCE 4.10.

Any solutions ?

Thanks

NEWT is very basic, it is not intended to replace Swing. I advise you again to use an higher level third party library for GUIs, for example Ardor3D UI or LibGDX Scene2D.

I am not using swing,awt or swt, only newt.
i draw the components myself with shaders.

If you do all of that in OpenGL,
you only need one GLDrawable and do all your overlaying
via OpenGL .. using RGBA .. etc.

I could render it in the same GLDrawable.

But sometimes the tooltip size makes it go out of the frame.
So I would prefer to have a separate frame for it otherwise when I have a small frame the tooltips might not be visible.

So how can I make the NEWT frame translucent and child of another frame ?
Are any of those possible ?

Have a look at the unit tests. We also have a translucent applet
on the test web page.

Basically you set opaque=false and no decorations for the NEWT frame,
then use RGBA8888 caps. Thats it.

setBackgroundOpaque on GLCapabilities.
took me some time to find it.

Also the clear color must be set to (0,0,0,0) if anything else with a 0 alpha it makes somekind
of foggy translucent background. don't know if it's a bug.


Thanks it works great.

I real like this NEWT framework, no bugs so far and easy to use.
Everything we need of an OpenGL frame.

Keep it simple that's great.

No it is the expected behavior.
