类型 TextInputContext

type TextInputContext struct {
	ID     ui.ID
	Bounds ui.Rect
	// Layer is the compositing layer captured by the focused hit.
	Layer     uint16
	Multiline bool
	ReadOnly  bool
	Secure    bool
	// NavigationKeys reports a field that asked for Up, Down, PageUp and
	// PageDown to be delivered to the application as raw ui.KeyEvents.
	NavigationKeys bool
	// Terminal reports a RoleTerminal hit. The native editor then is a
	// preedit surface in the fixed-pitch font: it draws only the text being
	// composed, with no caret or selection, and Bounds should be the cursor
	// cell. Plain keys reach the application as TextInsert events and the
	// rest as raw ui.KeyEvents (see ui.KeyEvent).
	Terminal bool
	// TextBounds, FontSize and TextColor are the text geometry the component
	// declared for this field. They fill whatever the returned TextInput leaves
	// unset, so a bare &TextInput{Editor: editor} draws its text exactly where
	// the field painted it; set them only to deliberately override.
	TextBounds ui.Rect
	FontSize   float32
	TextColor  ui.Color
