Detailed Description

A LineEdit owns a LineEditStyler. Applications do not construct one. Call Styler::bind() from onInvalidate(). When the overlay has no local options, bind uses the shared renderer from the style. Local options use a private clone. setRenderer() keeps an assigned renderer until it is cleared. A null renderer falls back on the next bind.

Appearance getters return effective tokens after bind. Setters write widget-local options. Measure, layout, and paint call the typed methods on this styler, not a public renderer accessor.

Member Function Documentation

◆ bind()

bool bind ( const Style & style,
const StyleOptions & styleOptions )
inherited

Returns true when the effective renderer or the effective options changed.

◆ init()

void init ( Renderer * renderer)
protectedinherited

A non-null renderer is a custom renderer. bind() keeps it until init() is called with 0, which falls back to the current style.
