[ENHANCMENT] TreeView selection control features #483

These should work, thank you. Sorry, I had trouble finding these things in the documentation. Maybe adding a simple Also, does setting

Yeah, its bi directional... maybe i should start enhancing all the component explorer components with some more "options" rather than just "disable"... I mean, the test app for treeview (when i was working out its native counter part) was pretty comprehensive: https://community.haxeui.org/uploads/default/original/1X/d6937fecb3fcfde249b91b8dc54939a85f64421f.gif Maybe i should start doing things like that in the component explorer also. Ill have a think about selectable, it might be a useful addition, im just not entirely sure when it would be useful (ie, disabled at least will give visual feedback that you cant do something). Cheers, |
When looking through the documentation and code for the TreeView component (which I am aware is experimental) I noticed that several missing features (or very poorly documented features) prevent the TreeView from being useful for user input, or anything more than display of a list of nodes.
The primary three I am looking for are:
The implementation of these three features would allow for user interaction with the TreeView to act as an input for the rest of the application, by allowing the user to select a node from the tree to "act upon".
A common use case for this feature would be a tree view which displays a directory structure, with the leaf nodes being individual files. The user could click on a leaf node to select a specific file.
As an aside, one potential additional feature (which I do not need for my application but may be needed in the future) is implementing the SelectionMode property on the TreeView, to allow the developer to define in what manner one (or more) list items may be selected, as seen in the ListView component.

Line 225 in d67dc45
This may be a more complicated feature to implement, as multi-selection may have more advanced rules for a tree view (should the user only be allowed to multi-select nodes with the same parent? or only nodes on the same "level"?), so it might be better set aside as its own issue.
