type
PaintableInvalidateContentsCallback = IO ()gi-gdk4 GI.Gdk.Interfaces.Paintable Emitted when the contents of the paintable change. Examples for such an event would be videos changing to the next frame or the icon theme for an icon changing.
type
PaintableInvalidateSizeCallback = IO ()gi-gdk4 GI.Gdk.Interfaces.Paintable Emitted when the intrinsic size of the paintable changes. This means the values reported by at least one of paintableGetIntrinsicWidth, paintableGetIntrinsicHeight or paintableGetIntrinsicAspectRatio has changed. Examples for such an event would be a paintable displaying the contents of a toplevel surface being resized.
-
gi-gdk4 GI.Gdk.Interfaces.Paintable Connect a signal handler for the invalidateContents signal, to be run after the default handler. When overloading is enabled, this is equivalent to
after paintable #invalidateContents callback
By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension. -
gi-gdk4 GI.Gdk.Interfaces.Paintable Connect a signal handler for the invalidateSize signal, to be run after the default handler. When overloading is enabled, this is equivalent to

gi-gdk4 GI.Gdk.Interfaces.Paintable Connect a signal handler for the invalidateContents signal, to be run before the default handler. When overloading is enabled, this is equivalent to
on paintable #invalidateContents callback
-
gi-gdk4 GI.Gdk.Interfaces.Paintable Connect a signal handler for the invalidateSize signal, to be run before the default handler. When overloading is enabled, this is equivalent to

paintableGetIntrinsicWidth :: (HasCallStack, MonadIO m, IsPaintable a) => a -> m Int32gi-gdk4 GI.Gdk.Interfaces.Paintable Gets the preferred width the paintable would like to be displayed at. Consumers of this interface can use this to reserve enough space to draw the paintable. This is a purely informational value and does not in any way limit the values that may be passed to paintableSnapshot. If the paintable does not have a preferred width, it returns 0. Negative values are never returned.
paintableInvalidateContents :: (HasCallStack, MonadIO m, IsPaintable a) => a -> m ()gi-gdk4 GI.Gdk.Interfaces.Paintable Called by implementations of GdkPaintable to invalidate their contents. Unless the contents are invalidated, implementations must guarantee that multiple calls of paintableSnapshot produce the same output. This function will emit the Paintable::invalidateContents signal. If a paintable reports the PaintableFlagsContents flag, it must not call this function.
paintableInvalidateSize :: (HasCallStack, MonadIO m, IsPaintable a) => a -> m ()gi-gdk4 GI.Gdk.Interfaces.Paintable Called by implementations of GdkPaintable to invalidate their size. As long as the size is not invalidated, paintable must return the same values for its intrinsic width, height and aspect ratio. This function will emit the Paintable::invalidateSize signal. If a paintable reports the PaintableFlagsSize flag, it must not call this function.
constructPopupAutohide :: (IsPopup o, MonadIO m) => Bool -> m (GValueConstruct o)gi-gdk4 GI.Gdk.Interfaces.Popup Construct a GValueConstruct with valid value for the “autohide” property. This is rarely needed directly, but it is used by new.
