Check evaluates all registered criterias and applies the first matching callback. It only invokes a callback if it has not been active. The noMatch callback is only called, if no active criteria match has been found. It will be called internally automatically, if some environment conditions like the screen size has changed. It is safe to be invoked on a nil pointer.

func (*Picker) BindText 

func (t *Picker) BindText(s *string) *Picker

BindText is a shortcut for TextProperty().Bind() and returning self. If used together with #SetSelected() the order matters. When populated from/to a model, you likely want to first select a default (by index) and then bind to the model, which reads the value from the given pointer. However if that is invalid, it does nothing, otherwise selects the right index by name.

func (Picker) Context 

func (b Picker) Context() Context

func (*Picker) Release

type Resource 

type Resource interface {
	Release() // Release clean up references and the resource must not be used afterwards anymore.
}

A Resource release method should be called for any resource, as soon as it is not required anymore to avoid memory leaks. Afterwards the Resource must not be used anymore. Even though we have a GC, we cannot rely on it, because the Resource may have registrations beyond our process, which requires holding global callback references, so that the outer system can call us. An example for this are go functions wrapped as callbacks in the wasm tier made available for the javascript DOM, like event handlers. Also cgo or rpc mechanism are possible.

type View 

type View interface {

	Scope() context.Context // Scope of the view, which is cancelled as soon as the view is destroyed.
	// contains filtered or unexported methods
}

A View is a absComponent on screen. It may not be visible, if it has not been attached yet. It is usually created through a constructor method (New<View>) and is a pointer to a struct, which itself may contain more components. It is not safe to be used concurrently and must only be modified by the UI thread.

type ViewGroup 

type ViewGroup interface {
	View
	ClearViews() ViewGroup
	AppendViews(views ...View) ViewGroup
}

ViewGroup is a generic interface which all view groups should support. Sadly go does not allow covariant return types in interfaces, so we have to define another signature set. See also https://github.com/golang/go/issues/30602.
