Struct cursive::views::ScrollView [−][src]
pub struct ScrollView<V> { /* fields omitted */ }
Expand description
Wraps a view in a scrollable area.
Implementations
Creates a new ScrollView around view
.
Returns the viewport in the inner content.
Returns the size of the content view, as it was on the last layout phase.
This is only the size the content thinks it has, and may be larger
than the actual size used by this ScrollView
.
Returns true
if the bottom row of the content is in view.
Return true
if the left-most column of the content is in view.
Return true
if the right-most column of the content is in view.
Defines the way scrolling is adjusted on content or size change.
The scroll strategy defines how the scrolling position is adjusted when the size of the view or the content change.
It is reset to ScrollStrategy::KeepRow
whenever the user scrolls
manually.
Defines the way scrolling is adjusted on content or size change.

Sets a callback to be run whenever scrolling happens.
This lets the callback access the ScrollView
itself (and its child)
if necessary.
If you just need to run a callback on &mut Cursive
, consider
