[−][src]Struct native_windows_gui::TrackBar
A trackbar is a window that contains a slider (sometimes called a thumb) in a channel, and optional tick marks. When the user moves the slider, using either the mouse or the direction keys, the trackbar sends notification messages to indicate the change.
Requires the trackbar
feature.
Builder parameters:
parent
: Required. The trackbar parent container.size
: The trackbar size.position
: The trackbar position.focus
: The control receive focus after being createdflags
: A combination of the TrackBarFlags values.range
: The value range of the trackbarselected_range
: The selected value range of the trackbar. Used withTrackBarFlags::RANGE
pos
: The current value of the trackbarbackground_color
: The background color the of the trackbar
Control events:
OnVerticalScroll
: When the value of a trackbar with the VERTICAL flags is changedOnHorizontalScroll
: When the value of a trackbar with the HORIZONTAL flags is changedMousePress(_)
: Generic mouse press events on the buttonOnMouseMove
: Generic mouse mouse eventOnMouseWheel
: Generic mouse wheel event

Implementations
impl TrackBar
[src]
pub fn builder() -> TrackBarBuilder
[src]
pub fn pos(&self) -> usize
[src]
Retrieves the current logical position of the slider in a trackbar. The logical positions are the integer values in the trackbar's range of minimum to maximum slider positions.
pub fn set_pos(&self, p: usize)
[src]
Sets the current logical position of the slider in a trackbar.
pub fn selection_range_pos(&self) -> Range<usize>
[src]
Retrieves the starting and ending position of the current selection range in a trackbar.
Only work for trackbar with the Range
flags
pub fn set_selection_range_pos(&self, value: Range<usize>)
[src]
Sets the range value of the trackbar
Only work for trackbar with the Range
flags
pub fn range_min(&self) -> usize
[src]
Retrieves the minimum position for the slider in a trackbar.
pub fn set_range_min(&self, min: usize)
[src]
Sets the minium logical position for the slider in a trackbar.
pub fn range_max(&self) -> usize
[src]
Retrieves the maximum position for the slider in a trackbar.
pub fn set_range_max(&self, max: usize)
[src]
Sets the maximum logical position for the slider in a trackbar.
pub fn tics_len(&self) -> usize
[src]
Retrieves the number of tick marks in a trackbar
pub fn tic_value(&self, index: usize) -> usize
[src]
Retrieves the logical position of a tick mark in a trackbar. The logical position can be any of the integer values in the trackbar's range of minimum to maximum slider positions.
pub fn enabled(&self) -> bool
[src]
Return true if the control user can interact with the control, return false otherwise
pub fn set_enabled(&self, v: bool)
[src]
Enable or disable the control
pub fn visible(&self) -> bool
[src]
Return 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))
pub fn set_visible(&self, v: bool)
[src]
Show or hide the control to the user
pub fn size(&self) -> (u32, u32)
[src]
Return the size of the button in the parent window
pub fn set_size(&self, x: u32, y: u32)
[src]
Set the size of the button in the parent window
pub fn position(&self) -> (i32, i32)
[src]
Return the position of the button in the parent window
pub fn set_position(&self, x: i32, y: i32)
[src]
Set the position of the button in the parent window
pub fn focus(&self) -> bool
[src]
Return true if the control currently has the keyboard focus
pub fn set_focus(&self)
[src]
Set the keyboard focus on the track bar
pub fn class_name(&self) -> &'static str
[src]
Winapi class name used during control creation
pub fn flags(&self) -> u32
[src]
Winapi base flags used during window creation
pub fn forced_flags(&self) -> u32
[src]
Winapi flags required by the control
