I'm a Java programmer who's rather new to Linux. I'm on Suse / Gnome and I need to create a window which:
- Is visually translucent/transparent. This is the usual alpha blending that composes a foreground image with a background image, while allowing the background image to be visible "through" the foreground image.
- Is transparent to mouse events, in other words the window accepts no mouse events and all such event are passed through to whatever lies underneath.
I successfully got the visual transparency but not the mouse event transparency. When I test the environment translucency capabilies with Java I got that:
- TRANSLUCENT = false - PERPIXEL_TRANSPARENT = true - PERPIXEL_TRANSLUCENT = true
The compositing is activated. I changed compositing type from OpenGL to XRender and vice versa. But it didn't change anything. Do I have to change of Window Manager or activate some options?
