ASS selectors

Detailed Description

AUI Style Sheets selector is a predicate whether view suit certain rules or not.

Classes
struct	ass::on_state::Hovered
	Hovered LESS-style subselector. More...
struct	ass::on_state::Activated
	Activated LESS-style subselector. More...
struct	ass::on_state::Focused
	Focused LESS-style subselector. More...
struct	ass::on_state::Disabled
	Disabled LESS-style subselector. More...
struct	ass::Selected
	Wraps another selector matching Selected views. More...

Typedefs
using	ass::sel = AAssSelector
	Runtime-type selector.
using	ass::c = class_of
	Selects views that are of the specified classes.
template<typename T>
using	ass::t = type_of<T>
	Selects views that are of the specified C++ types.

Typedef Documentation

c

using ass::c = class_of

Selects views that are of the specified classes.

This selector selects views that are of the specified classes. The selector can be accessed explicitly via ass::class_of.

For example:

{
  c(".btn"),
  BackgroundSolid(...),
}

This will select all views that belong to ".btn" ASS class.

sel

using ass::sel = AAssSelector

Runtime-type selector.

This type type-erases the selectors and allows to encapsulate.

t

template<typename T>

using ass::t = type_of<T>

Selects views that are of the specified C++ types.

This selector selects views that are of the specified classes. The selector can be accessed explicitly via ass::type_of.

For example:

{
  t<AButton>(),
  BackgroundSolid(...),
}

This will select all AButtons.

Function Documentation

operator&&()

template<aui::derived_from< IAssSubSelector > L, aui::derived_from< IAssSubSelector > R>

AndSelector< L, R > ass::operator&&	(	L	l,
		R	r )

Makes a selector that applies two selectors.

In this example, we want to select all views that match both ".btn" and ".accent".

{
  class_of(".btn-title") && class_of(".accent"),
  BackgroundSolid { 0xe81123_rgb }
},

operator>()

template<typename L, typename R, std::enable_if_t< std::is_base_of_v< IAssSubSelector, L > &&std::is_base_of_v< IAssSubSelector, R >, bool > = true>

DirectParentSubSelector< L, R > ass::operator>	(	L	l,
		R	r )

Makes direct parent subselector.

In this example, we want to select all views that have direct parent matching ".window-title" ASS class and then select the hovered ".close" subselector within them.

{
  class_of(".window-title") > class_of::hover(".close"),
  BackgroundSolid { 0xe81123_rgb }
},

operator>>()

template<typename L, typename R, std::enable_if_t< std::is_base_of_v< IAssSubSelector, L > &&std::is_base_of_v< IAssSubSelector, R >, bool > = true>

ParentSubSelector< L, R > ass::operator>>	(	L	l,
		R	r )

Makes indirect parent subselector.

Note

This selector is slower than direct parent subselector. If possible, use the latter.

In this example, we want to select all views that have indirect parent matching ".window-title" ASS class and then select the hovered ".close" subselector within them.

{
  class_of(".window-title") >> class_of::hover(".close"),
  BackgroundSolid { 0xe81123_rgb }
},
