## Description

A GtkStyle object encapsulates the information that provides the look and feel for a widget.

### Warning

In GTK+ 3.0, GtkStyle has been deprecated and replaced by GtkStyleContext.

Each GtkWidget has an associated GtkStyle object that is used when rendering that widget. Also, a GtkStyle holds information for the five possible widget states though not every widget supports all five states; see GtkStateType.

Usually the GtkStyle for a widget is the same as the default style that is set by GTK+ and modified the theme engine.

Usually applications should not need to use or modify the GtkStyle of their widgets.

### GTK_STYLE_ATTACHED()

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

`style` : | a GtkStyle.
Returns : | whether the style is attached to a window.

### gtk_style_new ()

    GtkStyle *          gtk_style_new                       (void);

### Warning

`gtk_style_new` has been deprecated since version 3.0 and should not be used in newly-written code. Use GtkStyleContext

Creates a new GtkStyle.

Returns : | a new GtkStyle.

### gtk_style_copy ()

    GtkStyle *          gtk_style_copy                      (GtkStyle *style);

### Warning

`gtk_style_copy` has been deprecated since version 3.0 and should not be used in newly-written code. Use GtkStyleContext instead

Creates a copy of the passed in GtkStyle object.

`style` : | a GtkStyle
Returns : | a copy of `style`. [transfer full]

### gtk_style_attach ()

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

### Warning

`gtk_style_attach` has been deprecated since version 3.0 and should not be used in newly-written code. Use `gtk_widget_style_attach()` instead

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)`

`style` : | a GtkStyle.
`window` : | a GdkWindow.
Returns : | Either `style`, or a newly-created GtkStyle. If the style is newly created, the style parameter will be unref'ed, and the new style will have a reference count belonging to the caller.

### gtk_style_detach ()

    void                gtk_style_detach                    (GtkStyle *style);

### Warning

`gtk_style_detach` has been deprecated since version 3.0 and should not be used in newly-written code. Use GtkStyleContext instead

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

`style` : | a GtkStyle

### gtk_style_has_context ()

    gboolean            gtk_style_has_context               (GtkStyle *style);

### Warning

`gtk_style_has_context` is deprecated and should not be used in newly-written code.

Returns whether `style` has an associated GtkStyleContext.

`style` : | a GtkStyle
Returns : | `TRUE` if `style` has a GtkStyleContext

Since 3.0

### Warning

`gtk_style_set_background` has been deprecated since version 3.0 and should not be used in newly-written code. Use `gtk_style_context_set_background()` instead

Sets the background of `window` to the background color or pixmap specified by `style` for the given state.

`style` : | a GtkStyle
`window` : | a GdkWindow
`state_type` : | a state

### Warning

`gtk_style_lookup_color` has been deprecated since version 3.0 and should not be used in newly-written code. Use `gtk_style_context_lookup_color()` instead

Looks up `color_name` in the style's logical color mappings, filling in `color` and returning `TRUE` if found, otherwise returning `FALSE`. Do not cache the found mapping, because it depends on the GtkStyle and might change when a theme switch occurs.

`style` : | a GtkStyle
`color_name` : | the name of the logical color to look up
`color` : | the GdkColor to fill in. [out]
Returns : | `TRUE` if the mapping was found.

### Warning

`gtk_paint_expander` has been deprecated since version 3.0 and should not be used in newly-written code. Use `gtk_render_expander()` instead

Draws an expander as used in GtkTreeView. `x` and `y` specify the center the expander. The size of the expander is determined by the "expander-size" style property of `widget`. (If widget is not specified or doesn't have an "expander-size" property, an unspecified default size will be used, since the caller doesn't have sufficient information to position the expander, this is likely not useful.) The expander is expander_size pixels tall in the collapsed position and expander_size pixels wide in the expanded position.

`cr` : | a cairo_t
`state_type` : | a state
`widget` : | the widget. [allow-none]

`x` : | the x position to draw the expander at
`y` : | the y position to draw the expander at
`expander_style` : | the style to draw the expander in; determines whether the expander is collapsed, expanded, or in an intermediate state.

## Signal Details

### The `"realize"` signal

    void                user_function                      (GtkStyle *style,
                                                            gpointer  user_data)      : Run First

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.

`style` : | the object which received the signal
`user_data` : | user data set when the signal handler was connected.

Since 2.4

### The `"unrealize"` signal

    void                user_function                      (GtkStyle *style,
                                                            gpointer  user_data)      : Run First

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.

`style` : | the object which received the signal
`user_data` : | user data set when the signal handler was connected.

Since 2.4
