table-resize-hack

HACK: table-resize-hack - this hack adds a frame around the table using `egui::Frame`, without the frame there are issues:
      1) the bottom row of the table extends outside the boundary of the `Resize` frame.
      2) the resize handle doesn't work from the bottom right corner due to the scrollbars.

example:

Resize::default()
    // ...
    .show(ui, | ui| {
        egui::Frame::new()        // <-- shouldn't need this frame
            .outer_margin(4.0)    // <-- shouldn't need this margin
            .show(ui, |ui | {
                // ...
                TableBuilder::new(ui)
                    // ...
                    .body( |mut body | {
                    // ...
                    });
            });
    });

tree-view-dir-activate-expand-hack

HACK: tree-view-dir-activate-expand-hack - force-expand directories that are 'activated'

When double clicking on a directory in an egui_ltreeview the directory state is expanded or collapsed this hack forces the node to be open.

Use inside the block that handles Action::Activate.

example:

let (_response, actions) = TreeView::new(...)
   // ...

for action in actions {
    match action {
        Action::Activate(activation) => {
            for node_id in activation.selected {
                // ... handle 'activation'

                // HACK: tree-view-dir-activate-expand-hack
                tree_view_state.expand_node(&node_id);
            }

        }
    }
}
