Detailed Description

Graphics system.

Member Function Documentation

init()

virtual void v1::gui_system::init ( )

inlinevirtualnoexcept

Initialize after construction.

Call this function directly after the constructor on the same thread.

is_gui_thread()

bool v1::gui_system::is_gui_thread ( ) const

inlinenoexcept

Check if this thread is the same as the gui thread.

make_unique()

static std::unique_ptr< gui_system > v1::gui_system::make_unique ( std::weak_ptr< gui_system_delegate > delegate = {} )

staticnoexcept

Make a gui_system instance.

This will instantiate a gui_system instance appropriate for the current operating system.

Parameters

delegate

An optional delegate.

Returns

A unique pointer to a gui_system instance.

make_window()

template<typename... Args>

std::shared_ptr< gui_window > v1::gui_system::make_window ( Args &&... args )

inline

Create a new window.

Parameters

args	The arguments that are forwarded to the constructor of hi::gui_window_win32.

Returns

A reference to the new window.

request_reconstrain()

void v1::gui_system::request_reconstrain ( )

noexcept

Request all windows to constrain.

Field Documentation

selected_theme

observable<std::string> v1::gui_system::selected_theme = "default"

The name of the selected theme.

writing_direction

unicode_bidi_class v1::gui_system::writing_direction = unicode_bidi_class::L

The writing direction.

The writing direction determines the initial writing direction of paragraphs.

When the value is R the user-interface should flip the horizontal layout, for example a row-layout-widget in flipped-mode should layout children ordered from right to left.

Note

The only values allowed are L and R.
