class (GUIObject w) => Window w where

Toplevel windows instantiate the class Window. Methods iconify :: w -> IO () Iconifies the window. deiconify :: w -> IO () Deiconifies the window. withdraw :: w -> IO () Withdraws the window. putWinOnTop :: w -> IO () Puts the window on top. putWinAtBottom :: w -> IO () Puts the window at bottom. screen :: Display -> Config w Sets the screen for this window. getScreen :: w -> IO Display Gets the screen from this window. getClassName :: w -> IO String Returns the resource class of the given window. getWindowState :: w -> IO WindowState Gets the current window state. aspectRatio :: AspectRatio -> Config w Sets the aspect ratio for the given window. getAspectRatio :: w -> IO AspectRatio Gets the aspect ratio of the given window. positionFrom :: Whom -> Config w Set 'Whom' to be Program or User. getPositionFrom :: w -> IO Whom Gets the current setting. sizeFrom :: Whom -> Config w Set 'Whom' to be Program or getSizeFrom :: w -> IO Whom Gets the current setting.

class (GUIObject w, GUIValue v) => HasText w v where

Objects containing text instantiate the class HasText. Methods text :: v -> Config w Sets the object's text. getText :: w -> IO v Gets the object's text. Instances (GUIValue v) => HasText Button v (GUIValue v) => HasText (CheckButton a) v (GUIValue v) => HasText (Dialog a) v (Window w, GUIValue v) => HasText (Icon w) v (GUIValue b, GUIValue c) => HasText (EntryField a b) c (GUIValue b, GUIValue c) => HasText (TextField a b) c (GUIValue c) => HasText (EnumField a b) c (GUIValue c) => HasText (RecordField a b) c (GUIValue b) => HasText Label b (GUIValue v) => HasText LabelFrame v (GUIValue v) => HasText MenuButton v (GUIValue v) => HasText MenuCascade v (GUIValue v) => HasText MenuCheckButton v (GUIValue v) => HasText MenuCommand v (GUIValue v) => HasText MenuRadioButton v (GUIValue b) => HasText Message b (GUIValue a) => HasText NoteBookPage a (GUIValue a, GUIValue b) => HasText (Prompt a) b (GUIValue v) => HasText (RadioButton a) v (GUIValue v) => HasText (Scale a) v (GUIValue b) => HasText TextItem b (Window w, GUIValue v) => HasText w v

maxSize :: (Window w) => Size -> Config w

getMaxSize :: (Window w) => w -> IO Size

Gets the maximum size of the window.

minSize :: (Window w) => Size -> Config w

Constraints the minimum size of the window.

getMinSize :: (Window w) => w -> IO Size

Gets the minimum size of the window.

raiseWin
