Godot UI — 快速参考¶

# Editor uses new "Modern" theme by default
# For game UI, use custom themes as before:
var theme := Theme.new()
theme.set_color(&"font_color", &"Label", Color.WHITE)
theme.set_font_size(&"font_size", &"Label", 24)

# Keyboard/gamepad focus (grab_focus still works)
func _ready() -> void:
    %StartButton.grab_focus()

# IMPORTANT: In 4.6, mouse hover is separate from keyboard focus
# Both can be active simultaneously on different controls
# Test your UI with BOTH mouse and keyboard/gamepad

# Focus neighbors (unchanged)
%Button1.focus_neighbor_bottom = %Button2.get_path()
%Button1.focus_neighbor_right = %Button3.get_path()

# Accordion-style collapsible container
# Add as parent of content you want to make collapsible
# Children show/hide when header is clicked
# Configure via editor properties or code

# Disable all mouse/focus interactions for a hierarchy
# Useful for disabling entire menu sections
%SettingsPanel.mouse_filter = Control.MOUSE_FILTER_IGNORE
# In 4.5+, this can propagate recursively to children

# Use tr() for all visible strings
label.text = tr("MENU_START_GAME")

# Use auto-wrap for labels (text length varies by language)
label.autowrap_mode = TextServer.AUTOWRAP_WORD_SMART

# Test with live translation preview in editor (4.5+)
