Trait containing all Scrollable methods.

Implementors

IconView, Layout, Scrollable, TextView, ToolPalette, TreeView, Viewport

Required Methods

fn border(&self) -> Option<Border>

Returns the size of a non-scrolling border around the outside of the scrollable. An example for this would be treeview headers. GTK+ can use this information to display overlayed graphics, like the overshoot indication, at the right position.

Returns

true if border has been set

border

return location for the results

fn hadjustment(&self) -> Option<Adjustment>

Retrieves the Adjustment used for horizontal scrolling.

Returns

horizontal Adjustment.

fn hscroll_policy(&self) -> ScrollablePolicy

Gets the horizontal ScrollablePolicy.

Returns

The horizontal ScrollablePolicy.

fn vadjustment(&self) -> Option<Adjustment>

Retrieves the Adjustment used for vertical scrolling.

Returns

vertical Adjustment.

fn vscroll_policy(&self) -> ScrollablePolicy

Gets the vertical ScrollablePolicy.

Returns

The vertical ScrollablePolicy.

fn set_hadjustment(&self, hadjustment: Option<&impl IsA<Adjustment>>)

Sets the horizontal adjustment of the Scrollable.

hadjustment

a Adjustment

fn set_hscroll_policy(&self, policy: ScrollablePolicy)

Sets the ScrollablePolicy to determine whether horizontal scrolling should start below the minimum width or below the natural width.

policy

the horizontal ScrollablePolicy

fn set_vadjustment(&self, vadjustment: Option<&impl IsA<Adjustment>>)

Sets the vertical adjustment of the Scrollable.

vadjustment

a Adjustment

fn set_vscroll_policy(&self, policy: ScrollablePolicy)

Sets the ScrollablePolicy to determine whether vertical scrolling should start below the minimum height or below the natural height.

policy

the vertical ScrollablePolicy

fn connect_hadjustment_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_hscroll_policy_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_vadjustment_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_vscroll_policy_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId
