Methods Description

std::string StyleSheet::data () const

Returns content as a string.

See also setData().

void StyleSheet::resolve (Widget * widget)

Resolves the styles for a given widget based on the parsed CSS rules. It iterates through the CSS selectors and applies matching rules to the widget.

void StyleSheet::resolveInline (Widget * widget, std::string & style)

Resolves inline style*s provided as a string (e.g., from the *style attribute in XML). The method splits the inline style*s into key-value pairs and applies them to the *widget.

void StyleSheet::setData (std::string & data)

Sets a new content data.

See also *data*().

void StyleSheet::setStyleProperty (Widget * widget, std::string & key, std::string & value)

Directly sets a style property for a widget. It adds the specified key and value pair to the widget’s style rules.

Vector4 StyleSheet::toColor (std::string & value)

Converts a CSS color value (e.g., named colors like “blue” or hexadecimal colors like “#ff0000”) to a Vector4 representing RGBA *value*s. It handles both named colors and hex codes (including short hex formats like #FFF).

float StyleSheet::toLength (std::string & value, bool & pixels)

Converts a length value (e.g., “10px” or “50%”) into a numeric value and returns whether the value is in pixels or percentages.
