double-click support

[afrantisak]

I don't see any double-click support... is that on the radar yet?

Yep, it is planned.

In the meantime, you can do something like this. In my case, I wanted my DirectoryTree to have the double click effect only on files. You can adjust this idea to whatever you need.

class DoubleClickDirectoryTree(DirectoryTree):
    """Instance of DirectoryTree requiring double click to open files"""

    def __init__(self, path: str, name: str = None) -> None:

        # Set the time to -2 seconds to avoid meeting immediate double click condition
        self.last_file_click: Tuple[float, DirEntry] = (
            time() - 2,
            DirEntry(None, False),
        )
        super().__init__(path, name)

    async def handle_tree_click(self, message: TreeClick[DirEntry]) -> None:
        dir_entry = message.node.data
        if not dir_entry.is_dir:

            # Get the current time and file entry
            current_click = (time(), dir_entry)

            # If the time difference is less than 1.5 seconds, it's a "double click"
            if (
                current_click[0] - self.last_file_click[0] < 1.5
                and current_click[1] == self.last_file_click[1]
            ):
                await self.emit(FileClick(self, dir_entry.path))

            self.last_file_click = current_click
        else:
            if not message.node.loaded:
                await self.load_directory(message.node)
                await message.node.expand()
            else:
                await message.node.toggle()
