getTextMetrics :: WidgetEnv s e -> StyleState -> TextMetrics Source #
Returns the text metrics of the active style.
getTextSize :: WidgetEnv s e -> StyleState -> Text -> Size Source #
Returns the size of the text using the active style and default options.
Arguments
| :: WidgetEnv s e | The widget environment. |
| -> StyleState | The active style. |
| -> TextMode | Whether to use single or multi line. |
| -> TextTrim | Whether to trim spacers or keep them. |
| -> Maybe Double | Maximum width (required for multi line). |
| -> Maybe Int | Max lines. |
| -> Text | Text to measure. |
| -> Size | The calculated size. |
Returns the size of the text using the active style.
getSingleTextLineRect Source #
Arguments
| :: WidgetEnv s e | The widget environment. |
| -> StyleState | The active style. |
| -> Rect | The bounding rect. |
| -> AlignTH | The horizontal alignment. |
| -> AlignTV | The vertical alignment. |
| -> Text | The text to measure. |
| -> Rect | The used rect. May be larger than the bounding rect. |
Returns the rect a single line of text needs to be displayed completely.
getTextGlyphs :: WidgetEnv s e -> StyleState -> Text -> Seq GlyphPos Source #
Returns the glyphs of a single line of text.
