Types

type Attachable

type Attachable interface {

	// Attached returns true if the control is directly or indirectly attached
	// to a window.
	Attached() bool

	// Detach is called when the control is directly or indirectly detached from a
	// window.
	// Detach should only be called by the parent of the control.
	Detach()

	// OnAttach subscribes f to be called whenever the control is attached.
	// OnDetach subscribes f to be called whenever the control is detached.
	OnAttach(func()) framework.EventSubscription
	OnDetach(func()) framework.EventSubscription
}

type Draw

type Draw interface {
	// Draw draws the control's visual apperance into the returned, new canvas.

	Size() math.Size

	// SetSize sets the size of the control to the specified value.
	// SetSize should only be called by the parent of the control during layout.
	SetSize(math.Size)
