NbtkStyle is a property data store that can read properties from a style sheet. It is queried with objects that implement the NbtkStylable interface.

typedef struct _NbtkStyle NbtkStyle;
The contents of this structure is private and should only be accessed using the provided API.
NbtkStyle * nbtk_style_get_default (void);
Return the default NbtkStyle object. This includes the current theme (if any).
Returns : |
a NbtkStyle object. This must not be freed or unref'd by applications |
NbtkStyle * nbtk_style_new (void);
Creates a new NbtkStyle object. This must be freed using g_object_unref when no longer required.
Returns : |
a newly allocated NbtkStyle |
gboolean nbtk_style_load_from_file (NbtkStyle *style, const gchar *filename, GError **error);
Load style information from the specified file.
void nbtk_style_get_property (NbtkStyle *style, NbtkStylable *stylable, GParamSpec *pspec, GValue *value);
Requests the property described in pspec
for the specified stylable
|
the style data store object |
|
a stylable to retreive the data for |
|
a GParamSpec describing the property required |
|
a GValue to place the return value in |
"style-notify"
signalvoid user_function (NbtkStylable *nbtkstylable, GParamSpec *arg1, gpointer user_data) : Run First / No Recursion / Has Details / Action / No Hooks
|
the object which received the signal. |
|
|
|
user data set when the signal handler was connected. |
"style-set"
signalvoid user_function (NbtkStylable *stylable, NbtkStyle *old_style, gpointer user_data) : Run Last
The ::style-set signal is emitted each time the NbtkStyle attached
to stylable
has been changed.
|
the NbtkStylable that received the signal |
|
the previously set NbtkStyle for stylable
|
|
user data set when the signal handler was connected. |
