xtd::forms::track_bar Class Reference

Inheritance diagram for xtd::forms::track_bar:

Definition

Represents a standard Windows track bar.

Header

#include <xtd/forms/track_bar>

Namespace

xtd::forms

Library

xtd.forms

Remarks

The track_bar is a scrollable control similar to the scroll_bar control. You can configure ranges through which the value of the value property of a track bar scrolls by setting the minimum property to specify the lower end of the range and the maximum property to specify the upper end of the range.

The large_change property defines the increment to add or subtract from the value property when clicks occur on either side of the scroll box. The track bar can be displayed horizontally or vertically.

You can use this control to input numeric data obtained through the value property. You can display this numeric data in a control or use it in code.

virtualnoexcept

Gets a value to be added to or subtracted from the value property when the scroll box is moved a large distance.

Returns

A numeric value. The default is 5.

Remarks

When the user presses the PAGE UP or PAGE DOWN key or clicks the track bar on either side of the scroll box, the value property changes according to the value set in the large_change property. You might consider setting the large_change value to a percentage of the height (for a vertically oriented track bar) or width (for a horizontally oriented track bar) value. This keeps the distance your track bar moves proportionate to its size.

You can use the OnScroll event to update other controls as the position of the scroll box changes.

Raising an event invokes the event handler through a delegate.

The on_scroll method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

Remarks

When overriding on_scroll(const event_args&) in a derived class, be sure to call the base class' on_scroll(const event_args&) method so that registered delegates receive the event.

on_value_changed()

virtual void xtd::forms::track_bar::on_value_changed ( const event_args & e )

protectedvirtual

Raises the track_bar::value_changed event.

Parameters

e	The event_args that contains the event data.

set_bounds_core()

overrideprotectedvirtual

Performs the work of setting the specified bounds of this control.

Parameters

x	The new left property value of the control.
y	The new top property value of the control.
width	The new width property value of the control.
height	The new height property value of the control.
specified	A bitwise combination of the bounds_specified values.

Reimplemented from xtd::forms::control.

set_client_size_core()

void xtd::forms::track_bar::set_client_size_core ( int32 width, int32 height )

overrideprotectedvirtual

Sets the size of the client area of the control.

Parameters

width	The client area width, in pixels.
height	The client area height, in pixels.

Reimplemented from xtd::forms::control.

wnd_proc()

void xtd::forms::track_bar::wnd_proc ( message & message )

overrideprotectedvirtual

Processes Windows messages.

Parameters

m	The Windows Message to process.

Remarks

All messages are sent to the wnd_proc method after getting filtered through the pre_process_message method.

Reimplemented from xtd::forms::control.
