runThemeReader :: (Reflex t, Monad m) => Behavior t Attr -> ThemeReader t m a -> m a Source #

Run a ThemeReader action with the given focus value

Manipulating images

withinImage :: Region -> Image -> Image Source #

Translates and crops an Image so that it is contained by the given Region.

imagesInRegion :: Reflex t => Behavior t Region -> Behavior t [Image] -> Behavior t [Image] Source #

Crop a behavior of images to a behavior of regions. See withinImage.

Running sub-widgets

pane Source #

Arguments

:: (MonadFix m, MonadHold t m, HasInput t m, HasImageWriter t m, HasDisplayRegion t m, HasFocusReader t m)
=> Dynamic t Region
-> Dynamic t Bool	Whether the widget should be focused when the parent is.
-> m a
-> m a

Low-level widget combinator that runs a child widget within a given region and context. This widget filters and modifies the input that the child widget receives such that: * unfocused widgets receive no key events * mouse inputs inside the region have their coordinates translated such that (0,0) is the top-left corner of the region * mouse drag sequences that start OFF the region are ignored * mouse drag sequences that start ON the region and drag off are NOT ignored
