Is there a way to make the background of Notepad++ text editor transparent like Eclipse?

enter image description here

Perhaps, there is a plugin which does this job.

Transparent background, while keeping the foreground (text) opaque? –  iglvzx May 9 '12 at 15:46
Yes @iglvzx. I heard that Eclipse has such capability but I don't know, whether this feature is supported by editor or some other environment (like KDE). –  user1050135 May 9 '12 at 17:21
Eclipse does have this ability. A custom plugin would have to be written for Notepad++ so that only the background, not the text is transparent. I'm guessing there's no point if the whole window is made transparent as this defeats the purpose of the entire editor window. CChris mentions in this SourceForge forum that Notepad++ dockable windows can't be made transparent, and that third party plugins have to be used. –  prrao May 9 '12 at 17:33

I wrote a program to make any window transparent. It will also make the menu bar, tool bar, etc. transparent so it may not be exactly what you need.

It runs in the background and is activated by using shift control 2 for 20% visibility up to shift control 9 for 90% visibility. shift control 0 goes back to full visibility.

The program is written in AutoIt. You can download the source and customize it as needed. AutoIt compiles programs to .exe in such a way that no dependencies are needed, such as DLLs or .NET.

As discussed in the comments above, this is not the exact solution being sought. –  iglvzx May 9 '12 at 19:11
Thanks @jftuga. I can try to change your AutoIt code. But I am not expert in it and so it is very difficult for me. It would be great if you can change your code to make the text/toolbar non transparent –  user1050135 May 10 '12 at 18:17

It isn't a plugin for Notepad++ but there is a simple way to get transparent applications such as Notepad++ if you have an Nvidia graphics card that supports nview.

You can set system wide or application specific transparency settings easily. Simply enable nview, then right click on the top bar on any window, select nView options, Transparent.

Here is a clear example of Notepad++ transparent example of notepad++ transparency in Windows 8

I realise this is hardware specific solution, but it is really useful and simple if do you have the right card. I know for sure it works on XPx86, Vistax64, Windows7x86 and Windows8x64 because I've used it for years on those platforms without any issues.
