TextAreaWithOneWildcard

TextArea with one wildcard. The format string (i.e. the TypedText set in setTypedText()) is expected to contain a wildcard <placeholder> from the text.

Note: the text converter tool converts the <...> to ascii value 2 which is then being replaced by a wildcard text.

Public Functions Documentation

draw

Draw this drawable.

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

Parameters:


invalidatedArea	The 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

getTextHeight


virtual int16_t getTextHeight	(			)

Gets the total height needed by the text, taking number of lines and line spacing into consideration.

Returns:

the total height needed by the text.

getWildcard


const Unicode::UnicodeChar * getWildcard	(			)	const

Gets the wildcard used in the TypedText as previously set using setWildcard().

The wildcard used in the text.

setWildcard

Sets the wildcard used in the TypedText where <placeholder> is placed.

Wildcard string must be a null-terminated UnicodeChar array.
