code snips welcome:

• two or more panels
• if a trigger is on, text green, off, text red
• display small image

If you're recommending one UI distribution over another, for this thread, I'd like real-world examples as to why. Particularly, situations where documentation of any dist excels beyond others.

I usually use Tk or a local webserver. If you want to see how Tk works and how its code looks like, intall it and run widget . I don't know what you mean by "panel" or "trigger", so I can't show you the snippets.

There is actually a demo in the distribution im pretty sure. You can always check that out as well.

EDIT: Also did you see my reply to your other question?

I don't know what you mean by trigger.

I too, usually use Tk. There is a simple GU code generator for it called vptk that I also use. Also, I created a menu builder "super widget".

Also, I've heard good things about the WxWidgets GTK toolkit and the Glade GUI builder for it (there are modules for generating Perl code from Glade description files). Not yet tried it.

Update: I meant GTK, not WxWidgets.

UI platforms differ only by the widgets they offer and what they look like

another differentiating criteria is supported platforms, and if binaries are available (ie how easy it is to build or get it running)

what you're looking for is trivial functionality any software called a "UI platform" supports

choosing by looks is easy/popular option, as is choosing by platform/build/binaries

I've gone with Tk for making a Win32 based GUI application,although most code is platform agnostic.It uses a queue of threads on the background so the the main UI thread does not freeze.The Windows specific part is that it uses Kernel events to sync i.e pause and resume the background thread when clicking on the "Pause/Resume" button in the UI.

The 'exe' is packaged with Par::Packer so it is portable and runs everywhere without installation.

I'm hosting it on Launchpad so you can take a look;well why not even contribute to it ? Unrar Extract and Recover on Launchpad
If you're looking for the binary distribution, it can be directly downloaded from UERSetup

Thanks nikosv, I've decided to stick with Wx after learning the ropes using the Wx::Demo mentioned already, but I will take a look at what you've got as I'm interested in the threading aspect that prevents main window blocking.

If it appears useful, I'll replicate it in Wx. My time's pretty limited lately working on my own electronics projects (code and hardware), so I can't say I'll be able to contribute, but who knows. I go off on tangents creating patches/PRs for random projects frequently, even when that was the farthest thing from my mind :)

If it appears useful, I'll replicate it in Wx.
