PlaceableView Padding Migration

Summary

As of this update, PlaceableView no longer has a custom content_padding property. Instead, it uses Godot's standard PanelContainer theme system for inner margins.

Migration Steps

Option 1: Theme Override in Scene (Recommended)

Add theme constant overrides directly to PlaceableView instances in your scene files:

[node name="PlaceableView" type="PanelContainer"]
theme_override_constants/margin_left= 4
theme_override_constants/margin_right= 4
theme_override_constants/margin_top= 4
theme_override_constants/margin_bottom= 4

Option 2: Global Theme Resource

Create or modify a Theme resource and set PanelContainer margins:

1. Create a new Theme resource or open your existing one
2. Navigate to: PanelContainer > Theme Constants
3. Set the following properties:
   • margin_left: 4
   • margin_right: 4
   • margin_top: 4
   • margin_bottom: 4
4. Apply the theme to your UI root or individual controls

Option 3: Runtime Override

Set margins programmatically in your scripts:

func _ready():
    var placeable_view= $PlaceableView
    placeable_view.add_theme_constant_override("margin_left",4)
    placeable_view.add_theme_constant_override("margin_right",4)
    placeable_view.add_theme_constant_override("margin_top",4)
    placeable_view.add_theme_constant_override("margin_bottom",4)

Why This Change?

• Follows Godot Best Practices: Uses built-in PanelContainer functionality instead of custom properties
• Better Integration: Works with Godot's theme system and style inheritance
• Simpler Code: Reduces custom code maintenance and complexity
• More Flexible: Can be configured per-instance, per-theme, or globally

Default Template

The plugin's PlaceableView template scene (placeable_view.tscn) has been updated with 4px margins on all sides as the default.
