interline | the spacing. |
Sets the Text interline spacing expressed as points.
void gcp::Text::JustificationChanged | ( | GtkJustification | justification | ) |
justification | a GtkJustification. |
Sets the justification for the Text. Only meaningful for multiline text.
bool gcp::Text::Load | ( | xmlNodePtr | node | ) | [virtual] |
node | the xml node representing the text. |
Loads the text in memory.
