Blender Python Tutorial : Custom Drawing / Layout Improvements [learn python for beginners]

In this Blender Python Tutorial, we will be looking at improving the layouts of our Operators/Panels.

Looking to learn Python for beginners? You are in the right place. Be sure to check out the Scripting Playlist!.

If you want to download the Finished result, you can find the Download link in our blog!.

By default, operator properties use an automatic user interface layout.

If you need more control you can create your own layout Function. It works like the Menu and Panel Draw Function.

There are many ways in which we can alter or change the layout of our operator and I just wanted to share some basic improvements to make our Operators and Panels look much better.

I hope you found this Blender Python Tutorial helpful and as always thanks for watching!.

Love this. I've learned this devoloping for Bforartists, a fork of blender focused on UI tuning. But it was all brute force learning. It's nice to actually understand a bit more. I'd love more tutorials like this. I'll check out you others! Thanks again for sharing.

Awesome explanation. This should be official blender documentation.

For a minor performance improvement and to shorten your source code slightly, you could replace your elif statement with else. A checkbox only has two states so if you test for one condition and it fails then the other is a given. Even if there are multiple tests and you only want to do something special when one is met (ie. you want to do something only if a value is 0 and nothing else) you can test for that one condition and then put an else for all the others. Else improves performance because it doesn't need to do a test (ie. checking if the checkbox is false). It is just what happens if all tests in that if statement fail. It shortens your code as that is all you need on the line "else:" and don't need to set up a conditional statement (ie. a == b).

This is the closest I've come to what I have in mind. Only thing I would add here is a way to change the font of the text. Thanks a lot!

PS: just noticed that the follow up vid to this you included fonts, great stuff

Really nice tutorial mate! Subscribed!

Also just to say, the fork also tries hide properties when not turned on.

Brilliant little tutorial! I was wondering, how could I use a ratio menu, or something that allows me to select between different options? Unlike check boxes, that allow you select multiple things.

[pavelsamoilenko]

how to make the background transparent on a layout?

[arko]

How can I add custom icons to blender's library so that I can use it later for my addons...or can how can I add customs in my panel /pie menu directly....without .DAT file

[josephstark]

Great improvement but you didn't implement snap to object feature
