Required Methods§
sourcefn border(&self) -> Option<Border>
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 overlaid graphics, like the overshoot indication, at the right position.
Returns
true
if @border has been set
border
return location for the results
sourcefn hadjustment(&self) -> Option<Adjustment>
fn hadjustment(&self) -> Option<Adjustment>
sourcefn hscroll_policy(&self) -> ScrollablePolicy
fn hscroll_policy(&self) -> ScrollablePolicy
sourcefn vadjustment(&self) -> Option<Adjustment>
fn vadjustment(&self) -> Option<Adjustment>
sourcefn vscroll_policy(&self) -> ScrollablePolicy
fn vscroll_policy(&self) -> ScrollablePolicy
sourcefn set_hadjustment(&self, hadjustment: Option<&impl IsA<Adjustment>>)
fn set_hadjustment(&self, hadjustment: Option<&impl IsA<Adjustment>>)
sourcefn set_hscroll_policy(&self, policy: ScrollablePolicy)
fn set_hscroll_policy(&self, policy: ScrollablePolicy)
Sets the ScrollablePolicy
.
The policy determines whether horizontal scrolling should start below the minimum width or below the natural width.
policy
the horizontal ScrollablePolicy
sourcefn set_vadjustment(&self, vadjustment: Option<&impl IsA<Adjustment>>)
fn set_vadjustment(&self, vadjustment: Option<&impl IsA<Adjustment>>)
sourcefn set_vscroll_policy(&self, policy: ScrollablePolicy)
fn set_vscroll_policy(&self, policy: ScrollablePolicy)
Sets the ScrollablePolicy
.
The policy determines whether vertical scrolling should start below the minimum height or below the natural height.
policy
the vertical ScrollablePolicy
