Public Functions Documentation

draw

virtual void draw(const Rect &invalidatedArea)

Draw this drawable.

It is a requirement that the draw implementation does not draw outside the region specified by invalidatedArea.

Parameters:
invalidatedAreaThe sub-region of this drawable that needs to be redrawn, expressed in coordinates relative to its parent (e.g. for a complete redraw, invalidatedArea will be (0, 0, width, height).

Reimplements: touchgfx::TextArea::draw

invalidateContent

virtual void invalidateContent()const

Tell the framework that the contents of the Drawable needs to be redrawn.

If the Drawable is invisible, nothing happens. Subclasses of Drawable are encouraged to implement this function and invalidate as little as possible, i.e. the smallest rectangle covering the visual element(s) drawn by the widget.

Reimplements: touchgfx::TextArea::invalidateContent

TextAreaWithWildcardBase

Protected Functions Documentation

calculateBoundingArea

virtual TextArea::BoundingArea calculateBoundingArea()const

Calculates the minimum bounding rectangle of this text area and correlates it with the containing text, to get the bounding area.

Note: The bounding rectangle is adjusted according to alignment and rotation.

Returns:

The bounding area.
