[[Pan widget class.
|
|
|
|
This widget positions its contents (set using @Efl.Content.content) relative to the widget itself.
|
|
This is particularly useful for large content which does not fit inside its container. In this case
|
|
only a portion is shown.
|
|
|
|
The position of this "window" into the content can be changed using @Efl.Ui.Pan.pan_position.
|
|
This widget does not provide means for a user to change the content's position (like scroll bars).
|
|
This widget is meant to be used internally by other classes like @Efl.Ui.Scroll.Manager.
