 Posted: Tue Jun 05, 2007 12:45 pm Post subject: Cairo, GTK default font and widget state |
 |
|
Hello,
I have implemented a GtkTreeView with my custom cell rendered.
Now, I would like to render the treeview items taking into account:
- the current widget state (disabled, selected, etc)
- the default font for widgets.
The colors and the font may change when a new theme is applied, for exemple. How can I retreive these values?
Notice that I use Cairo to render the item text, so I need to have a Cairo description of the default font...
Thank you
Guilhem |

You can get the current widget state with GtkStateType. You can retrieve information about the default colors of the text for the state from the GtkTreeView's style at GTK_WIDGET(treeview)->style. This is a GtkStyle object.
As for the font, the style structure includes a PangoFontDescription member called font_desc. You can get information about the font such as style, size, and family from the font description. From this information, you can set the Cairo font. Check out: http://developer.gnome.org/doc/API/2.0/pango/pango-Fonts.html |
