To make an HBoxContainer dynamically resize with its image contents in Godot 4.3, follow these steps:

Core Setup

• Parent with ScrollContainer: Place your HBoxContainer inside a ScrollContainer to enable scrolling when content exceeds visible area. Set the scroll direction (horizontal/vertical) in the ScrollContainer properties[5].

• Container Settings:

  • Enable Expand and set Stretch Mode to Keep Aspect on all child TextureRect nodes[2].
  • Apply Size Flags (Fill and Expand) to each TextureRect to ensure proportional scaling[2][3].

Dynamic Resizing

For automatic width adjustment when adding/removing images:

# After adding/removing children:
$HBoxContainer.queue_sort()  # Forces layout update
$ScrollContainer.update_scroll()  # Refreshes scroll boundaries

If automatic resizing fails (common with dynamic content), manually calculate and set the container width:

var total_width = 0
for child in $HBoxContainer.get_children():
    total_width += child.size.x
total_width += $HBoxContainer.get_constant("separation") * ($HBoxContainer.get_child_count() - 1)
$HBoxContainer.custom_minimum_size.x = total_width

Alternative Approach

For wrapping behavior, replace HBoxContainer with an HFlowContainer (ensuring it's inside a fixed-size Control node). This automatically wraps overflowing items to new rows while scaling contents[2][4].
