synchronize :: BitMap -> IO b -> IO b

GUIObject BitMap

Internal.

Methods

toGUIObject :: BitMap -> GUIOBJECT

cname :: BitMap -> String

cset :: GUIValue a => BitMap -> ConfigID -> a -> IO BitMap

cget :: GUIValue a => BitMap -> ConfigID -> IO a

HasFile BitMap

Bitmaps can be read from files.

Methods

filename :: String -> Config BitMap

getFileName :: BitMap -> IO String

HasBorder BitMap

A bitmap object has a configureable border (if implicitely displayed inside a label widget).

Methods

borderwidth :: Distance -> Config BitMap

getBorderwidth :: BitMap -> IO Distance

relief :: Relief -> Config BitMap

getRelief :: BitMap -> IO Relief

HasSize BitMap

You can specify the size of the containing label, if the bitmap is implicitely displayed inside a label widget.

Methods

width :: Distance -> Config BitMap

getWidth :: BitMap -> IO Distance

height :: Distance -> Config BitMap

getHeight :: BitMap -> IO Distance

size :: Size -> Config BitMap

getSize :: BitMap -> IO Size

HasColour BitMap

A bitmap object has a configureable foreground and background colour (if implicitely displayed inside a label widget).

Methods

legalColourID :: BitMap -> ConfigID -> Bool

setColour :: BitMap -> ConfigID -> Colour -> IO BitMap

getColour :: BitMap -> ConfigID -> IO Colour

Widget BitMap

A bitmap object has standard widget properties (concerning focus, cursor / if implicitely displayed inside a label widget).

Methods

cursor :: CursorDesignator ch => ch -> Config BitMap

getCursor :: BitMap -> IO Cursor

takeFocus :: Bool -> Config BitMap

getTakeFocus :: BitMap -> IO Bool

BitMapDesignator BitMap

Internal.

Methods

toBitMap :: BitMap -> BitMapHandle

newBitMap

Arguments

:: [Config BitMap]

the list of configuration options for this bitmap object.

-> IO BitMap

A bitmap object.

Constructs a new bitmap object and returns a handler. The bitmap object can be packed like a widget, then it is implicitely displayed inside a label widget.

data BitMapHandle

The BitMapHandle datatype - a handle for a bitmap resource.
