GOStyle * go_styled_object_get_style (GOStyledObject *gso);
Simply an accessor function that returns gso->style, without referencing it.
gso : |
a GOStyledObject |
| Returns : | the styled object's GOStyle |
GOStyle * go_styled_object_get_auto_style (GOStyledObject *gso);
This function returns a new style that is initialized with the auto values for gso.
Caller is responsible for the result.
gso : |
a GOStyledObject |
| Returns : | a new GOStyle |
gboolean go_styled_object_set_style (GOStyledObject *gso, GOStyle *style);
Sets a new style for gso, and emits "style-changed" signal. This function
does not take ownership of style.
gso : |
a GOStyledObject |
style : |
a GOStyle |
| Returns : | TRUE if new style may lead to change of object size, which
happens when changing font size for example.
|
void go_styled_object_apply_theme (GOStyledObject *gso, GOStyle *style);
Apply appropriate theme style if meaningful, i.e. properties with
auto flag set to TRUE should be changed to default theme value.
gso : |
a GOStyledObject |
style : |
a GOStyle that will be themed |
void go_styled_object_style_changed (GOStyledObject *gso);
Called when the style changed. Might emit a signal if meaningful.
gso : |
a GOStyledObject |
GODoc * go_styled_object_get_document (GOStyledObject *gso);
gso : |
|
| Returns : |
gboolean go_styled_object_set_cairo_fill (GOStyledObject const *so, cairo_t *cr);
so : |
|
cr : |
|
| Returns : |
gboolean go_styled_object_set_cairo_line (GOStyledObject const *so, cairo_t *cr);
so : |
|
cr : |
|
| Returns : |
