Member Function Documentation

§ create_params()

forms::create_params xtd::forms::up_down_button::create_params ( ) const
overrideprotectedvirtual

Gets the required creation parameters when the control handle is created.

Returns
A create_params that contains the required creation parameters when the handle to the control is created.

Reimplemented from xtd::forms::button_base.

§ default_size()

drawing::size xtd::forms::up_down_button::default_size ( ) const
inlineoverrideprotectedvirtual

Gets the default size of the control.

Returns
The default Size of the control.

Reimplemented from xtd::forms::button_base.

§ on_handle_created()

void xtd::forms::up_down_button::on_handle_created ( const event_args e)
overrideprotectedvirtual

Overrides control::on_handle_created(const event_args&)

Parameters
eA EventArgs that contains the event data.

Reimplemented from xtd::forms::control.

§ orientation() [1/2]

virtual forms::orientation xtd::forms::up_down_button::orientation ( ) const
inlinevirtual

Gets a value indicating the horizontal or vertical orientation of the up down button.

Returns
One of the orientation values.

§ orientation() [2/2]

virtual up_down_button& xtd::forms::up_down_button::orientation ( forms::orientation  orientation)
virtual

Sets a value indicating the horizontal or vertical orientation of the up down button.

Parameters
orientationOne of the orientation values.
Whenthe orientation property is set to orientation::horizontal, the scroll box moves from left to right as the value increases. When the orientation property is set to orientation::vertical, the scroll box moves from bottom to top as the Value increases.

§ set_range()

void xtd::forms::up_down_button::set_range ( int  min_value,
int  max_value 
)
inline

Sets the minimum and maximum values for a track_bar.

Parameters
min_valueThe lower limit of the range of the track bar.
max_valueThe upper limit of the range of the track bar.
Remarks
You can use this method to set the entire range for the track_bar at the same time. To set the minimum or maximum values individually, use the minimum and maximum properties. If the min_value parameter is greater than the max_value parameter, max_value is set equal to min_value.

§ to_string()

ustring xtd::forms::up_down_button::to_string ( ) const
inlineoverridevirtual

Returns a string that represents the track_bar control.

Returns
A string that represents the current progress_bar.
Remarks
The return string includes the type and the values for the minimum, maximum, and value properties.

Reimplemented from xtd::forms::control.

§ wnd_proc()

void xtd::forms::up_down_button::wnd_proc ( message message)
overrideprotectedvirtual

Processes Windows messages.

Parameters
mThe 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.
