how to create a custom buffer layout using custom layer
4 months, 1 week ago Edited by Josh Paley on March 15, 2021, 7:07 a.m. Reason: Initial post
I have been trying to figure how to create custom buffer layout on start up of 4coder but for the life of me I can't get it to work.
so here is the code that I'm working with. What am I missing here?

how to create a custom buffer layout using custom layer
4 months, 1 week ago Edited by Simon Anciaux on March 15, 2021, 4:45 p.m.
I haven't worked with the last version of 4coder so I may not be aware of changes in that version.

Here is a article in the wiki about getting started with 4coder custom layer, but be aware that it's for version before 4.1.7. Most notably the way bindings work has changed (the old way might still work, but as I said, I haven't tried it yet).

Did you compile your platform layer after doing the change ?

You should keep the default_framework_init (defined in 4coder_default_framework.cpp) because it's initializing 4coder systems, it's not responsible for the "layout" of the UI.

You've copied the code for the open_panel_hsplit command there, but if you just want to split the view horizontally you just need to call the command. It's also not the right place to do that. You need the custom_layer_init function to stay mostly the same, but change the startup hook. The default startup hook is defined in 4coder_default_hook.cpp, you can modify it, or create a different one and setting it up to be called. In the default_startup hook, the function that sets up the default panels is default_4coder_side_by_side_panels (from 4coder_default_framework.cpp). You can look at that and modify it to do what you want.

Don't forget to compile the custom layer (with 4coder closed) afterward.

Here is a small example. I didn't compile it so it might just not work.

how to create a custom buffer layout using custom layer
4 months, 1 week ago
I am so dumb, I've been banging my head against the wall for a day or two. I just realized the same thing, literally 5 mins before reading your post.

thx for your response and the help is greatly appreciated.
