Types

type IWidget

type IWidget interface {
	gowid.ICompositeWidget
	gowid.IClickTracker
	gowid.IIdentity
	ClickPending() bool
}

IWidget is implemented by any widget that contains exactly one exposed subwidget (ICompositeWidget), that can distinguish itself from another IWidget (via the ID() function), and that can track a mouse click prior to a mouse release (simply with a bool flag, in this case)

type Widget

type Widget struct {
	Callbacks *gowid.Callbacks
	gowid.SubWidgetCallbacks
	gowid.ClickCallbacks
	gowid.AddressProvidesID
	gowid.IsSelectable
	// contains filtered or unexported fields
}
