Detailed Description

template<typename RendererT, typename OptionsT>
class Pt::Forms::StyleBinder< RendererT, OptionsT >

Manages the active renderer, binding mode, and generation counters needed for local prepare bookkeeping. All Forms style controllers that follow the extracted-slice pattern derive from this template.

Template Parameters

RendererT	Concrete Style::Facet renderer type. Must expose create() and prepare(const StyleOptions&, const OptionsT&).
OptionsT	Widget-local style options type. Must expose hasOverrides() and generation() const.

Member Function Documentation

◆ bind() [1/2]

RendererT * bind	(	const Pt::Forms::Style &	style,
		const StyleOptions &	options,
		const OptionsT &	localOptions
	)

Selects either the shared style renderer (SharedRenderer) or a private override clone (CustomOverrides). Shared style renderers are synchronized through Style::reset() and are therefore not prepared locally here. Private override clones are prepared immediately with the current style and local options. This call always leaves custom renderer mode.

◆ bind() [2/2]

RendererT * bind	(	RendererT &	renderer,
		const StyleOptions &	options,
		const OptionsT &	localOptions
	)

Assigns a custom renderer explicitly and prepares it with the current options.

◆ rebind()

RendererT * rebind	(	const Pt::Forms::Style &	style,
		const StyleOptions &	options,
		const OptionsT &	localOptions
	)

Re-prepares the current custom renderer when the local prepare inputs changed. Shared style renderers and override clones are reacquired through the current Style by delegating to the style-path bind.
