GTK_STYLE_ATTACHED()

#define GTK_STYLE_ATTACHED(style)       (GTK_STYLE (style)->attach_count > 0)

gtk_style_new ()

GtkStyle *
gtk_style_new (void);

Creates a new GtkStyle.

gtk_style_copy ()

GtkStyle *
gtk_style_copy (GtkStyle *style);

Creates a copy of the passed in GtkStyle object.

gtk_style_attach ()

GtkStyle *
gtk_style_attach (GtkStyle *style,
                  GdkWindow *window);

Attaches a style to a window; this process allocates the colors and creates the GC’s for the style - it specializes it to a particular visual. The process may involve the creation of a new style if the style has already been attached to a window with a different style and visual.

Since this function may return a new object, you have to use it in the following way: style = gtk_style_attach (style, window)

[skip]

gtk_style_detach ()

void
gtk_style_detach (GtkStyle *style);

Detaches a style from a window. If the style is not attached to any windows anymore, it is unrealized. See gtk_style_attach().

The “context” property

  “context”                  GtkStyleContext *

GtkStyleContext to get style from.

Owner: GtkStyle

Flags: Read / Write / Construct Only

The “realize” signal

void
user_function (GtkStyle *style,
               gpointer  user_data)

Emitted when the style has been initialized for a particular visual. Connecting to this signal is probably seldom useful since most of the time applications and widgets only deal with styles that have been already realized.

Flags: Run First

Since: 2.4

The “unrealize” signal

void
user_function (GtkStyle *style,
               gpointer  user_data)

Emitted when the aspects of the style specific to a particular visual is being cleaned up. A connection to this signal can be useful if a widget wants to cache objects as object data on GtkStyle. This signal provides a convenient place to free such cached objects.

Flags: Run First
