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 a Source #

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.

data Theme Source #

A Theme is a record of colors, font etc., to customize a DecorationStyle.

For a collection of Themes see XMonad.Util.Themes

data Decoration (ds :: Type -> Type) 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 Source #	The long `LayoutModifier` instance for the `Decoration` type. In `redoLayout` we check the state: if there is no state we initialize it. The state is `diff`ed against the list of windows produced by the underlying layout: removed windows get deleted and new ones decorated by `createDecos`, which will call `decorate` to decide if a window must be given a `Rectangle`, in which case a decoration window will be created. 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 `Decoration` `LayoutModifier`. Otherwise we call `handleEvent`, which will call the appropriate `DecorationStyle` methods to perform its tasks.

class (Read (ds a), Show (ds a), Eq a) => DecorationStyle (ds :: Type -> Type) a where Source #

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.

Minimal complete definition

Nothing

Methods

describeDeco :: ds a -> String Source #

The description that the Decoration modifier will display.

shrink :: ds a -> Rectangle -> Rectangle -> Rectangle Source #

Shrink the window's rectangle when applying a decoration.

decorationEventHook :: ds a -> DecorationState -> Event -> X () Source #

The decoration event hook

decorationCatchClicksHook Source #

Arguments

:: 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 Rectangle Source #

The pure version of the main method, decorate.

decorate :: ds a -> Dimension -> Dimension -> Rectangle -> Stack a -> [(a, Rectangle)] -> (a, Rectangle) -> X (Maybe Rectangle) Source #

Given the theme's decoration width and height, the screen rectangle, the windows stack, the list of windows and rectangles returned by the underlying layout and window to be decorated, tupled with its rectangle, produce a Just Rectangle or Nothing if the window is not to be decorated.
