- module XMonad.Layout.LayoutModifier
Usage:
This module is intended for layout developers, who want to decorate their layouts. End users will not find here very much for them.
For examples of DecorationStyle
instances you can have a look at
XMonad.Layout.SimpleDecoration, XMonad.Layout.Tabbed,
XMonad.Layout.DwmStyle, or XMonad.Layout.TabBarDecoration.
decoration :: (DecorationStyle ds a, Shrinker s) => s -> Theme -> ds a -> l a -> ModifiedLayout (Decoration ds s) l aSource
A layout modifier that, with a Shrinker
, a Theme
, a
DecorationStyle
, and a layout, will decorate this layout
according to the decoration style provided.
For some usage examples see XMonad.Layout.DecorationMadness.
A Theme
is a record of colors, font etc., to customize a
DecorationStyle
.
For a collection of Theme
s see XMonad.Util.Themes
Theme | |
|
The default xmonad Theme
.
data Decoration ds s a Source
The Decoration
LayoutModifier
. This data type is an instance
of the LayoutModifier
class. This data type will be passed,
together with a layout, to the ModifiedLayout
type constructor
to modify the layout by adding decorations according to a
DecorationStyle
.
(DecorationStyle ds Window, Shrinker s) => LayoutModifier (Decoration ds s) Window | The long In The state is After that we resync the updated state with the windows' list and then we process the resynced stated (as we do with a new state). First we map the decoration windows, we update each decoration to reflect any decorated window's change, and we insert, in the list of windows and rectangles returned by the underlying layout, the decoration for each window. This way xmonad will restack the decorations and their windows accordingly. At the end we remove invisible/stacked windows. Message handling is quite simple: when needed we release the state
component of the |
(Read s, Read (ds a)) => Read (Decoration ds s a) | |
(Show s, Show (ds a)) => Show (Decoration ds s a) |
data DecorationMsg Source
A Decoration
layout modifier will handle SetTheme
, a message
to dynamically change the decoration Theme
.
class (Read (ds a), Show (ds a), Eq a) => DecorationStyle ds a whereSource
The DecorationStyle
class, defines methods used in the
implementation of the Decoration
LayoutModifier
instance. A
type instance of this class is passed to the Decoration
type in
order to decorate a layout, by using these methods.
describeDeco :: ds a -> StringSource
The description that the Decoration
modifier will display.
shrink :: ds a -> Rectangle -> Rectangle -> RectangleSource
Shrink the window's rectangle when applying a decoration.
decorationEventHook :: ds a -> DecorationState -> Event -> X ()Source
The decoration event hook
decorationCatchClicksHookSource
:: ds a | |
-> Window | |
-> Int | distance from the left where the click happened on the decoration |
-> Int | distance from the right where the click happened on the decoration |
-> X Bool |
A hook that can be used to catch the cases when the user clicks on the decoration. If you return True here, the click event will be considered as dealt with and no further processing will take place.
decorationWhileDraggingHook :: ds a -> CInt -> CInt -> (Window, Rectangle) -> Position -> Position -> X ()Source
This hook is called while a window is dragged using the decoration. The hook can be overwritten if a different way of handling the dragging is required.
decorationAfterDraggingHook :: ds a -> (Window, Rectangle) -> Window -> X ()Source
This hoook is called after a window has been dragged using the decoration.
pureDecoration :: ds a -> Dimension -> Dimension -> Rectangle -> Stack a -> [(a, Rectangle)] -> (a, Rectangle) -> Maybe RectangleSource
The pure version of the main method, decorate
.
decorate :: ds a -> Dimension -> Dimension -> Rectangle -> Stack a -> [(a, Rectangle)] -> (a, Rectangle) -> X (Maybe Rectangle)Source

data DefaultDecoration a Source
The default DecorationStyle
, with just the default methods'
implementations.
Eq a => DecorationStyle DefaultDecoration a | |
Read (DefaultDecoration a) | |
Show (DefaultDecoration a) |
isInStack :: Eq a => Stack a -> a -> BoolSource
True if the window is in the Stack
. The Window
comes second
to facilitate list processing, even though w `isInStack` s
won't
work...;)
fi :: (Integral a, Num b) => a -> bSource
Short-hand for fromIntegral
findWindowByDecoration :: Window -> DecorationState -> Maybe (OrigWin, (Window, Maybe Rectangle))Source
