I would like to create a user interface that allows users to click on an image in a dialogue and that will then select items in the scene. Similar to visual Selector.. Is this something I achieve using the GeUserArea class? You can either answer with yes or no or elaborate, lol I am happy with either.

Thanks,

Shawn

Can GeUserArea only be used in a dialog or can it be added to the attributes manager?

Thanks,

I don't think so, but afaik you can subclass a CustomGui, can't you? CustomGui's can be added in both.

PS: Here ya go, ready for the script-manager, you only have to add some paths to your icons you want to show.

Some response would be quite nice. Those code-snippets don't just fly through the window after calling my big-friend Coding God.

Lol sorry niklas. I hadn't had a chance to look at them yet. Thank you for giving me the examples. To be honest I didn't even know there was a code example because I had checked it on my phone and the email that was sent to me didn't have an example. Sorry for the lack of response. Thanks again. I do appreciate your assistance.

So I have to excuse in return. I assumed you did already see it as you have opened another Thread at that time.

Niklas - the code you posted above, is brilliant, and i have a question:

Is it possible to use GeUserArea similar to the above ( ie clickable bitmaps ) but in the ObjectManager properties for a Plugin?

I thought itd be quicker to ask before i waste a lot of time trying something out that isnt possible!

I might just use the BITMAPBUTTON description element, but would be useful to know.. Plus it avoids registering icon id`s..

Not from Python, unfortunately. That would require implementing a CustomGui plugin.

PS: Wonder why I was so harsh back then, sorry for that.

Hi Niklas - sorry i forgot to mention in this case i am using C++.

BTW - i would also be annoyed if i posted a whole script for somebody and didn't get any thanks for it!
