XMonad.Util.XUtils

Contents

Description

A module for painting on the screen

Synopsis

Usage:

withSimpleWindow :: WindowConfig -> [String] -> X a -> X a Source #

Like showSimpleWindow, but fully manage the window; i.e., destroy it after the given function finishes its execution.

showSimpleWindow Source #

Arguments

:: WindowConfig

Window config.

-> [String]

Lines of text to show.

-> X Window 

Create a window, then fill and show it with the given text. If you are looking for a version of this function that also takes care of destroying the window, refer to withSimpleWindow.

data WindowConfig Source #

The config for a window, as interpreted by showSimpleWindow.

The font winFont can either be specified in the TODO format or as an xft font. For example:

winFont = "xft:monospace-20"

or

winFont = "-misc-fixed-*-*-*-*-20-*-*-*-*-*-*-*"

Methods

def :: WindowConfig #

data WindowRect Source #

What kind of window we should be.

Constructors

CenterWindow

Centered, big enough to fit all the text.

CustomRect Rectangle

Completely custom dimensions.

averagePixels :: Pixel -> Pixel -> Double -> X Pixel Source #

Compute the weighted average the colors of two given Pixel values.

This function masks out any alpha channel in the passed pixels, and the result has no alpha channel. X11 mishandles Pixel values with alpha channels and throws errors while producing black pixels.

createNewWindow :: Rectangle -> Maybe EventMask -> String -> Bool -> X Window Source #

Create a simple window given a rectangle. If Nothing is given only the exposureMask will be set, otherwise the Just value. Use showWindow to map and hideWindow to unmap.

showWindow :: Window -> X () Source #

Map a window

showWindows :: [Window] -> X () Source #

the list version

hideWindow :: Window -> X () Source #

unmap a window

hideWindows :: [Window] -> X () Source #

the list version

deleteWindow :: Window -> X () Source #

destroy a window

deleteWindows :: [Window] -> X () Source #

the list version

paintWindow Source #

Arguments

:: Window

The window where to draw

-> Dimension

Window width

-> Dimension

Window height

-> Dimension

Border width

-> String

Window background color

-> String

Border color

-> X () 

Fill a window with a rectangle and a border

paintAndWrite Source #

Arguments

:: Window

The window where to draw

-> XMonadFont

XMonad Font for drawing

-> Dimension

Window width

-> Dimension

Window height

-> Dimension

Border width

-> String

Window background color

-> String

Border color

-> String

String color

-> String

String background color

-> [Align]

String Alignments

-> [String]

Strings to be printed

-> X () 

Fill a window with a rectangle and a border, and write | a number of strings to given positions

paintTextAndIcons Source #

Arguments

:: Window

The window where to draw

-> XMonadFont

XMonad Font for drawing

-> Dimension

Window width

-> Dimension

Window height

-> Dimension

Border width

-> String

Window background color

-> String

Border color

-> String

String color

-> String

String background color

-> [Align]

String Alignments

-> [String]

Strings to be printed

-> [Placement]

Icon Placements

-> [[[Bool]]]

Icons to be printed

-> X () 

Fill a window with a rectangle and a border, and write | a number of strings and a number of icons to given positions

stringToPixel :: (Functor m, MonadIO m) => Display -> String -> m Pixel Source #

Get the Pixel value for a named color: if an invalid name is given the black pixel will be returned.

pixelToString :: MonadIO m => Display -> Pixel -> m String Source #

Convert a Pixel into a String.

This function removes any alpha channel from the Pixel, because X11 mishandles alpha channels and produces black.

fi :: (Integral a, Num b) => a -> b Source #

Short for fromIntegral.
