Detailed Description#

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

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

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.

Examples: examples/7guis/flight_booker/src/main.cpp.

◆ sel#

using ass::sel = AAssSelector

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

◆ t#

template<typename T>

using ass::t = type_of<T>

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>

NotSelector< L > ass::operator! ( L l )

In this example, we want to select all views that match ".btn" but don't match ".accent".

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

◆ operator&&()#

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

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

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 )

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 )

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 }
},
