highlight code tree node

[SamC]

Hello，
I found that the nearest codetree node from current caret will be highlighted，however，that highlight is not worked for user defined codetree node.
Like the picture below，the caret is at line9, the nearest codetree node is at line6 which is user defined node, but the highlight node is at line4 which is built-in node.
Is it possible to highlight user defined node( mark2) in this case?
BTW, is it possible to change the background color of current node?
Thanks!

No, because the 'bookmark' tree node is not considered by app, when app is searching for current tree node. app considers only nodes calculated by tree-helper or lexer. It is not simple to change, sorry. Bookmark tree node is not 'internal' for app.

EDIT.
Next thinking: maybe it's possible to change the plugin 'code-tree bookmarks' for this. pls study its code. plugin can handle the on_state with APPSTATE_CODETREE_SET_SELECTION .

>BTW, is it possible to change the background color of current node?

As your screenshot shows, current node HAS the special highlight. So what more do you suggest?

Thanks, Any api to change the node highlight color? I will try to mark the bookmark node with different color.

Edit:
Any api to highlight several certain codetree nodes? Didn't find relevant commands in Tree_proc.

No, app don't have the API to change color of nodes.

But we have TREE_ITEM_SET_ICON, so you can make .png icon file 16x16, load it to imagelist (get imagelist handle: TREE_GET_IMAGELIST), and assign icon to any node.

I made this proposal
https://github.com/Alexey-T/CudaText/issues/5536
wait until it will be added, and then you can add 'state image index' per each node. using the same imagelist.

Plugin 'code-tree bookmarks' fixed and updated. Now clicking on bookmark line in editor - makes tree selection on correct bookmark node.

Thanks，the following API is used to set the range of code item~
TREE_ITEM_SET_RANGE: Should be used only for code-tree. Sets range for tree-item. Param "text" must be 4-tuple of int (start_x, start_y, end_x, end_y).

[main Alexey]

Yes, this API. it was used not OK, author set the range of lenght= 1 char. I fixed it to set range of length= line_len.

Note, if you click below the last bookmark , or between 2 bookmarks, codetree cannot sync to bookmark node. you must click exactly on bookmarked line (before the line end).
