source · [−]pub struct ScrollBar {
pub handle: ControlHandle,

Expand description
A window can display a data object, such as a document or a bitmap, that is larger than the window’s client area. When provided with a scroll bar, the user can scroll a data object in the client area to bring into view the portions of the object that extend beyond the borders of the window.
Requires the scroll-bar
feature.
Builder parameters:
parent
: Required. The scroll bar parent container.size
: The scroll bar size.position
: The scroll bar position.focus
: The control receive focus after being createdflags
: A combination of the ScrollBarFlags values.ex_flags
: A combination of win32 window extended flags. Unlikeflags
, ex_flags must be used straight from winapirange
: The value range of the scroll barpos
: he current value of the scroll bar
Control events:
OnVerticalScroll
: When the value of a scrollbar with the VERTICAL flags is changedOnHorizontalScroll
: When the value of a scrollbar with the HORIZONTAL flags is changedMousePress(_)
: Generic mouse press events on the buttonOnMouseMove
: Generic mouse eventOnMouseWheel
: Generic mouse wheel event

Implementations
sourceimpl ScrollBar
impl ScrollBar
pub fn builder<'a>() -> ScrollBarBuilder
sourcepub fn pos(&self) -> usize
pub fn pos(&self) -> usize
Retrieves the current logical position of the slider in a scrollbar. The logical positions are the integer values in the scrollbar’s range of minimum to maximum slider positions.
sourcepub fn set_pos(&self, p: usize)
pub fn set_pos(&self, p: usize)
Sets the current logical position of the slider in a scrollbar. If the value is out of range he value is rounded up or down to the nearest valid value..
sourcepub fn enabled(&self) -> bool
pub fn enabled(&self) -> bool
Returns true if the control user can interact with the control, return false otherwise
sourcepub fn set_enabled(&self, v: bool)
pub fn set_enabled(&self, v: bool)
Enable or disable the control
sourcepub fn visible(&self) -> bool
pub fn visible(&self) -> bool
Returns true if the control is visible to the user. Will return true even if the control is outside of the parent client view (ex: at the position (10000, 10000))
sourcepub fn set_visible(&self, v: bool)
pub fn set_visible(&self, v: bool)
Show or hide the control to the user
sourcepub fn set_position(&self, x: i32, y: i32)
pub fn set_position(&self, x: i32, y: i32)
Sets the position of the button in the parent window
sourcepub fn class_name(&self) -> &'static str
pub fn class_name(&self) -> &'static str
Winapi class name used during control creation
sourcepub fn forced_flags(&self) -> u32
pub fn forced_flags(&self) -> u32
Winapi flags required by the control
