Functions
Description
GtkStyleProperties provides the storage for style information that is used by GtkStyleContext and other GtkStyleProvider implementations.
Before style properties can be stored in GtkStyleProperties, they
must be registered with gtk_style_properties_register_property().
Unless you are writing a GtkStyleProvider implementation, you
are unlikely to use this API directly, as gtk_style_context_get()
and its variants are the preferred way to access styling information
from widget implementations and theming engine implementations
should use the APIs provided by GtkThemingEngine instead.
Functions
gtk_style_properties_clear ()
void
gtk_style_properties_clear (GtkStyleProperties *props);
Clears all style information from props
.
gtk_style_properties_get ()
void gtk_style_properties_get (GtkStyleProperties *props,GtkStateFlags state,...);
Retrieves several style property values from props
for a
given state.
Parameters
props |
||
state |
state to retrieve the property values for |
|
... |
property name /return value pairs, followed by |
Since 3.0
gtk_style_properties_get_property ()
gboolean gtk_style_properties_get_property (GtkStyleProperties *props,const gchar *property,GtkStateFlags state,GValue *value);
Gets a style property from props
for the given state. When done with value
,
g_value_unset() needs to be called to free any allocated memory.
Parameters
props |
||
property |
style property name |
|
state |
state to retrieve the property value for |
|
value |
return location for the style property value. |

gtk_style_properties_get_valist ()
void gtk_style_properties_get_valist (GtkStyleProperties *props,GtkStateFlags state,va_list args);
Retrieves several style property values from props
for a given state.
Parameters
props |
||
state |
state to retrieve the property values for |
|
args |
va_list of property name/return location pairs, followed by |

gtk_style_properties_lookup_color ()
GtkSymbolicColor * gtk_style_properties_lookup_color (GtkStyleProperties *props,const gchar *name);
gtk_style_properties_lookup_color has been deprecated since version 3.8 and should not be used in newly-written code.
GtkSymbolicColor is deprecated.
Returns the symbolic color that is mapped
to name
.
Since 3.0
gtk_style_properties_lookup_property ()
gboolean gtk_style_properties_lookup_property (const gchar *property_name,GtkStylePropertyParser *parse_func,GParamSpec **pspec);
gtk_style_properties_lookup_property has been deprecated since version 3.8 and should not be used in newly-written code.
This code could only look up custom properties and those are deprecated.
Returns TRUE if a property has been registered, if pspec
or
parse_func
are not NULL, the GParamSpec and parsing function
will be respectively returned.
Parameters
property_name |
property name to look up |
|
parse_func |
return location for the parse function. |
[out] |
pspec |
return location for the GParamSpec. |
[out][transfer none] |

gtk_style_properties_map_color ()
void gtk_style_properties_map_color (GtkStyleProperties *props,const gchar *name,GtkSymbolicColor *color);
gtk_style_properties_map_color has been deprecated since version 3.8 and should not be used in newly-written code.
GtkSymbolicColor is deprecated.
Maps color
so it can be referenced by name
. See
gtk_style_properties_lookup_color()
Since 3.0
gtk_style_properties_merge ()
void gtk_style_properties_merge (GtkStyleProperties *props,const GtkStyleProperties *props_to_merge,gboolean replace);
Merges into props
all the style information contained
in props_to_merge
. If replace
is TRUE, the values
will be overwritten, if it is FALSE, the older values
will prevail.
Parameters
props |
||
props_to_merge |
a second GtkStyleProperties |
|
replace |
whether to replace values or not |
Since 3.0
gtk_style_properties_new ()
GtkStyleProperties *
gtk_style_properties_new (void);
Returns a newly created GtkStyleProperties
GtkStylePropertyParser ()
gboolean (*GtkStylePropertyParser) (const gchar *string,GValue *value,GError **error);
gtk_style_properties_register_property ()
void gtk_style_properties_register_property (GtkStylePropertyParser parse_func,GParamSpec *pspec);
gtk_style_properties_register_property has been deprecated since version 3.8 and should not be used in newly-written code.
Code should use the default properties provided by CSS.
Registers a property so it can be used in the CSS file format.
This function is the low-level equivalent of
gtk_theming_engine_register_property(), if you are implementing
a theming engine, you want to use that function instead.
Since 3.0
gtk_style_properties_set ()
void gtk_style_properties_set (GtkStyleProperties *props,GtkStateFlags state,...);
Sets several style properties on props
.
Since 3.0
gtk_style_properties_set_property ()
