/** @brief Auto wrapped (multi-line) text, auto shrank to min. dimensions. |
| 439 |
|
* |
| 440 |
|
* This widgets is intended for large text blocks which are expected to require |
| 441 |
|
* the text to be automatically wrapped (i.e. auto inserted line breaks) such |
| 442 |
|
* that it would not exceed the label's maximum allowed width according to its |
| 443 |
|
* parent container. |
| 444 |
|
* |
| 445 |
|
* This class overrides get_preferred_height_for_width_vfunc() to fix the |
| 446 |
|
* default behaviour of Gtk::Label, which by default calculates a height under |
| 447 |
|
* the assumption that EVERY word of the text had a line break, which would |
| 448 |
|
* cause the label to claim much more vertical space than actually required for |
| 449 |
|
* the text. |
