Detailed Description

The state the widget is in.

The numeric value of the state is used as an index into theme-values to select the appropriate visual style.

Member Function Documentation

◆ begin()

static constexpr widget_state hi::v1::widget_state::begin ( )

inlinestaticconstexprnoexcept

Start of the iteration of all possible widget states.

◆ end()

static constexpr widget_state hi::v1::widget_state::end ( )

inlinestaticconstexprnoexcept

End of the iteration of all possible widget states.

◆ focus()

constexpr bool hi::v1::widget_state::focus ( ) const

inlineconstexprnoexcept

Get if the window has keyboard focus.

◆ layer()

constexpr size_t hi::v1::widget_state::layer ( ) const

inlineconstexprnoexcept

Get the layer of a widget.

The layer between 0 and 3 is used to determine how to visual distinct widget at different nesting levels.

◆ mode()

constexpr widget_mode hi::v1::widget_state::mode ( ) const

inlineconstexprnoexcept

Get the mode of a widget.

See also: widget_mode

◆ operator T()

template<std::integral T>
requires (sizeof(T) >= 2)

constexpr hi::v1::widget_state::operator T ( ) const

inlineexplicitconstexprnoexcept

Get the numeric value of the window state.

The numeric value is used for indexing into theme tables for quick lookup of, for example, the background color of the widget in a certain state.

◆ operator++()

constexpr widget_state & hi::v1::widget_state::operator++ ( )

inlineconstexprnoexcept

Increment the widget-state.

This is used to iterate over each unique widget_state, to fill in the theme tables.

◆ phase()

constexpr widget_phase hi::v1::widget_state::phase ( ) const

inlineconstexprnoexcept

Get the phase of the widget.

See also: widget_phase

◆ set_active()

constexpr widget_state & hi::v1::widget_state::set_active ( bool active )

inlineconstexprnoexcept

Set if the window is active widget.

See also: widget_phase

◆ set_focus()

constexpr widget_state & hi::v1::widget_state::set_focus ( bool focus )

inlineconstexprnoexcept

Set if the window has keyboard focus.

◆ set_hover()

constexpr widget_state & hi::v1::widget_state::set_hover ( bool hover )

inlineconstexprnoexcept

Set if the mouse hovers over the widget.

See also: widget_phase

◆ set_layer()

constexpr widget_state & hi::v1::widget_state::set_layer ( size_t layer )

inlineconstexprnoexcept

Set the layer of the widget.

Parameters

layer The layer is modulo 4.

◆ set_mode()

constexpr widget_state & hi::v1::widget_state::set_mode ( widget_mode mode )

inlineconstexprnoexcept

Set the mode of a widget.

See also: widget_mode

◆ set_pressed()

constexpr widget_state & hi::v1::widget_state::set_pressed ( bool pressed )

inlineconstexprnoexcept

Set if the mouse/finger presses the widget.

See also: widget_phase

◆ set_value()

constexpr widget_state & hi::v1::widget_state::set_value ( widget_value value )

inlineconstexprnoexcept

Set the value of the widget.

See also: widget_value

◆ size()

static constexpr size_t hi::v1::widget_state::size ( )

inlinestaticconstexprnoexcept

The number if possible widget states.

◆ value()

constexpr widget_value hi::v1::widget_state::value ( ) const

inlineconstexprnoexcept

Get the value of the widget.

See also: widget_value
