on_tree_node_selected(self, event) only triggers on enter key

[philippeflorent]

Hi,

is there a way to trigger async def on_tree_node_selected(self, event)

when using the arrow keys ? so I dont have to press enter every time or use the mouse

thanks

Could you explain what you are trying to achieve? This sounds like an example of an XY Problem

For example, do you just want the nodes expanded by default? Or trigger expanded by some other action?

[philippeflorent]

please dont overcomplicate/overwhelm here, it is no xyz... issue

if you used a tree before, you probably noticed that when using arrows, it highlights the next item in the tree

but I have to press enter to actually select the highlighted node, and so so trigger that function

it is annoying beyond believe

• I need a function that triggers when the cursor moves to another item without pressing enter
• or to change the behavior of the tree so that moving the cursor also selects the item the cursor is on

I'm simply trying to understand what you're actually trying to achieve. The XY problem is essentially asking about your attempted solution (i.e. "how to trigger on_tree_node_selected"), rather than your actual problem (i.e. "how to expand the node when highlighted").

I asked for clarification precisely not to waste anyone's time by over-complicating things.

@philippeflorent Tom is giving up his free time in order to help you. If he were to answer your question literally then the answer is "no". So please give him the benefit of the doubt in the future.

I think you want to respond to when a node is highlighted, which is quite different from selected.

You can find the details in the tree widget's documentation.

I understand that and I did not mean to be offensive in any way
There is also nothing in my answer who discarded his, we were just not on the same page I guess

we all use computers and we all noticed using arrow keys in a file explorer was selecting the next file AND updating any info's displayed about that file

voila that's all I was asking, I just thought it was that crystal clear

and a crystal clear answer would be : no but you can use on_tree_node_highlighted

thanks for your help guys

so for people wanting to implement the same thing

    def select_node(self, event):
       ...

    async def on_tree_node_selected(self, event) -> None:
        self.select_node(event)

    async def on_tree_node_highlighted(self, event) -> None:
        self.select_node(event)
