Types ¶

type FocusManager ¶

type FocusManager interface {
	RegisterFocusButton(key string, btn *widget.Button)
	SetPendingFocus(key string)
	SetScrollWidgets(sc *widget.ScrollContainer, slider *widget.Slider)
	SaveScrollPosition()
	RestoreScrollPosition()
	// Zone-based navigation
	RegisterNavZone(name string, zoneType string, keys []string, columns int)
	SetNavTransition(fromZone string, direction int, toZone string, toIndex int)
}

FocusManager interface for focus restoration and scroll management. Implemented by BaseScreen, used by sub-sections that need to register focusable buttons and manage scroll position.

type FocusRestorer ¶

type FocusRestorer interface {
	// GetPendingFocusButton returns the button that should receive focus after rebuild
	GetPendingFocusButton() *widget.Button
	// ClearPendingFocus clears the pending focus state
	ClearPendingFocus()
}

FocusRestorer is implemented by screens that support focus restoration after rebuilds

type ScreenCallback ¶

type ScreenCallback interface {
	SwitchToLibrary()
	SwitchToDetail(gameCRC string)
	SwitchToSettings()
	SwitchToScanProgress(rescanAll bool)
	LaunchGame(gameCRC string, resume bool)
	Exit()
	GetWindowWidth() int             // For responsive layout calculations
	RequestRebuild()                 // Request UI rebuild after state changes
	GetPlaceholderImageData() []byte // Get raw placeholder image data for missing artwork
	GetRDB() *rdb.RDB                // Get RDB for metadata lookups
	GetExtensions() []string         // Get supported ROM file extensions
}
