Returns the width of the character at the specified position. | |
int | count () const |
Returns the total number of characters. | |
QString | grapheme (int index) const |
Returns the grapheme at the specified index. | |
QgsTextCharacterFormat | graphemeFormat (int index) const |
Returns the character format for the grapheme at the specified index. | |
int | graphemeFormatCount () const |
Returns the number of grapheme formats available. | |
QStringList | graphemes () const |
Returns the list of graphemes contained in the text. | |
double | maximumCharacterDescent () const |
Returns the maximum descent of any character found in the text. | |
double | maximumCharacterHeight () const |
Returns the maximum height of any character found in the text. | |
void | setGraphemeFormats (const QVector< QgsTextCharacterFormat > &formats) |
Sets the character formats associated with the text graphemes(). | |
