Description

Native is the interface implemented by all widgets that can provide a GdkSurface for widgets to render on.

The obvious example of a Native is Window.

Synopsis

newtype Native = Native (ManagedPtr Native)
class (GObject o, IsDescendantOf Native o) => IsNative o
toNative :: (MonadIO m, IsNative o) => o -> m Native
nativeCheckResize :: (HasCallStack, MonadIO m, IsNative a) => a -> m ()
nativeGetForSurface :: (HasCallStack, MonadIO m, IsSurface a) => a -> m Widget
nativeGetRenderer :: (HasCallStack, MonadIO m, IsNative a) => a -> m Renderer
nativeGetSurface :: (HasCallStack, MonadIO m, IsNative a) => a -> m Surface
nativeGetSurfaceTransform :: (HasCallStack, MonadIO m, IsNative a) => a -> m (Double, Double)

toNative :: (MonadIO m, IsNative o) => o -> m Native Source #

Cast to Native, for types for which this is known to be safe. For general casts, use castTo.

Methods

Overloaded methods

checkResize

nativeCheckResize Source #

Arguments

:: (HasCallStack, MonadIO m, IsNative a)
=> a	`self`: a `Native`
-> m ()

Reposition and resize a Native.

Widgets need to call this function on their attached native widgets when they receive a new size allocation.

getForSurface

nativeGetForSurface Source #

Arguments

:: (HasCallStack, MonadIO m, IsSurface a)
=> a	`surface`: a `Surface`
-> m Widget	Returns: the `Native` that is associated with `surface`

Finds the GtkNative associated with the surface.

getRenderer

nativeGetRenderer Source #

Arguments

:: (HasCallStack, MonadIO m, IsNative a)
=> a	`self`: a `Native`
-> m Renderer	Returns: the renderer for `self`

Returns the renderer that is used for this Native.

getSurface

nativeGetSurface Source #

Arguments

:: (HasCallStack, MonadIO m, IsNative a)
=> a	`self`: a `Native`
-> m Surface	Returns: the surface of `self`

Returns the surface of this Native.

getSurfaceTransform

nativeGetSurfaceTransform Source #

Arguments

:: (HasCallStack, MonadIO m, IsNative a)
=> a	`self`: a `gtkNative`
-> m (Double, Double)

Retrieves the surface transform of self. This is the translation from self's surface coordinates into self's widget coordinates.
