GI.Gtk.Objects.Style

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

In GTK+ 3.0, GtkStyle has been deprecated and replaced by
'GI.Gtk.Objects.StyleContext.StyleContext'.

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

Usually the Style 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 Style of their widgets.

Methods

applyDefaultBackground

styleApplyDefaultBackground :: (HasCallStack, MonadIO m, IsStyle a, IsWindow b) => a -> Context -> b -> StateType -> Int32 -> Int32 -> Int32 -> Int32 -> m ()

Deprecated: (Since version 3.0)Use StyleContext instead

No description available in the introspection data.

copy

styleCopy

Arguments

:: (HasCallStack, MonadIO m, IsStyle a)

=> a

style: a Style

-> m Style

Returns: a copy of style

Deprecated: (Since version 3.0)Use StyleContext instead

Creates a copy of the passed in Style object.

detach

styleDetach

Arguments

:: (HasCallStack, MonadIO m, IsStyle a)

=> a

style: a Style

-> m ()

Deprecated: (Since version 3.0)Use StyleContext instead

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

getStyleProperty

styleGetStyleProperty

Arguments

:: (HasCallStack, MonadIO m, IsStyle a)

=> a

style: a Style

-> GType

widgetType: the GType of a descendant of Widget

-> Text

propertyName: the name of the style property to get

-> m GValue

Queries the value of a style property corresponding to a widget class is in the given style.

Since: 2.16

hasContext

styleHasContext

Arguments

:: (HasCallStack, MonadIO m, IsStyle a)

=> a

style: a Style

-> m Bool

Returns: True if style has a StyleContext

Returns whether style has an associated StyleContext.

Since: 3.0

lookupColor

styleLookupColor

Arguments

:: (HasCallStack, MonadIO m, IsStyle a)

=> a

style: a Style

-> Text

colorName: the name of the logical color to look up

-> m (Bool, Color)

Returns: True if the mapping was found.

Deprecated: (Since version 3.0)Use styleContextLookupColor instead

Looks up colorName 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 Style and might change when a theme switch occurs.

Since: 2.10

lookupIconSet

styleLookupIconSet

Arguments

:: (HasCallStack, MonadIO m, IsStyle a)

=> a

style: a Style

-> Text

stockId: an icon name

-> m IconSet

Returns: icon set of stockId

Deprecated: (Since version 3.0)Use styleContextLookupIconSet instead

Looks up stockId in the icon factories associated with style and the default icon factory, returning an icon set if found, otherwise Nothing.

new

styleNew

Arguments

:: (HasCallStack, MonadIO m)

=> m Style

Returns: a new Style.

Deprecated: (Since version 3.0)Use StyleContext

Creates a new Style.

renderIcon

styleRenderIcon

Arguments

:: (HasCallStack, MonadIO m, IsStyle a, IsWidget b)

=> a

style: a Style

-> IconSource

source: the IconSource specifying the icon to render

-> TextDirection

direction: a text direction

-> StateType

state: a state

-> Int32

size: the size to render the icon at (IconSize). A size of (GtkIconSize)-1 means render at the size of the source and don’t scale.

-> Maybe b

widget: the widget

-> Maybe Text

detail: a style detail

-> m Pixbuf

Returns: a newly-created Pixbuf containing the rendered icon

Deprecated: (Since version 3.0)Use renderIconPixbuf instead

Renders the icon specified by source at the given size according to the given parameters and returns the result in a pixbuf.

setBackground

styleSetBackground

Arguments

:: (HasCallStack, MonadIO m, IsStyle a, IsWindow b)

=> a

style: a Style

-> b

window: a Window

-> StateType

stateType: a state

-> m ()

Deprecated: (Since version 3.0)Use styleContextSetBackground instead

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