Data types

data Border Source

Window borders Constructors BorderSimple Displays a thin border around the window. BorderDouble Displays a double border. Windows only. BorderSunken Displays a sunken border. BorderRaised Displays a raised border. BorderStatic Displays a border suitable for a static control. Windows only BorderNone No border Instances Eq Border Read Border Show Border Typeable Border BitMask Border

Text

class Textual w where Source

Widgets with a label or text field. Methods text :: Attr w String Source The text of a widget. It is interpreted differently for for different widgets, for example, the title of a frame or the content of a static text control. appendText :: w -> String -> IO () Source Instances Textual StatusField

class Literate w where Source

Widgets with a font. Methods font :: Attr w FontStyle Source The font of the widget. fontSize :: Attr w Int Source The font size. fontWeight :: Attr w FontWeight Source The font weight. fontFamily :: Attr w FontFamily Source The font family. fontShape :: Attr w FontShape Source The font style. fontFace :: Attr w String Source The font face: determines a platform dependent font. fontUnderline :: Attr w Bool Source Is the font underlined? textColor :: Attr w Color Source Text color. textBgcolor :: Attr w Color Source Text background color

Rendering

class Dimensions w where Source

Widgets that have a size. Methods outerSize :: Attr w Size Source The outer size of a widget (in pixels). position :: Attr w Point Source The (relative) position of a widget. area :: Attr w Rect Source The occupied area. bestSize :: ReadAttr w Size Source The preferred size of a widget. clientSize :: Attr w Size Source The area available for client use (i.e. without the border etc). virtualSize :: Attr w Size Source The virtual size of a widget (ie. the total scrolling area)

class Colored w where Source

Methods bgcolor :: Attr w Color Source The background color. color :: Attr w Color Source The (foreground) color

class Visible w where Source

Visible widgets. Methods visible :: Attr w Bool Source Is the widget visible? refresh :: w -> IO () Source Refresh the widget explicitly. fullRepaintOnResize :: Attr w Bool Source Should the widget be fully repainted on resize? This attribute only has effect when set at creation. If False, you will have to repaint the new window area manually at a resize, but flickering caused by background redraws can be prevented in this way. (False by default)

class Bordered w where Source

Widgets with a border. Methods border :: Attr w Border Source Specify the border of a widget.

Hierarchy

class Child w where Source

Widgets that are part of a hierarchical order. Methods parent :: ReadAttr w (Window ()) Source The parent widget.

class Parent w where Source

Parent widgets. Methods children :: ReadAttr w [Window ()] Source Get the child widgets of a window. clipChildren :: Attr w Bool Source Reduce flicker by not redrawing the background under child controls. This attribute has to be set at creation time. (True by default)

class Closeable w where Source

Widgets that can be closed. Methods close :: w -> IO () Source Close the widget.

Containers

class Selection w where Source

Widgets with a single selection (radio group or listbox) Methods selection :: Attr w Int Source The current selection as a zero-based index. Certain widgets return -1 when no item is selected.

class Selections w where Source

Widget with zero or more selections (multi select list boxes) Methods selections :: Attr w [Int] Source The currently selected items in zero-based indices.

class Items w a | w -> a where Source

Widgets containing certain items (like strings in a listbox) Methods itemCount :: ReadAttr w Int Source Number of items. items :: Attr w [a] Source All the items as a list. This attribute might not be writable for some widgets (like radioboxes) item :: Int -> Attr w a Source An item by zero-based index. itemDelete :: w -> Int -> IO () Source Delete an item. Only valid for writeable items. itemsDelete :: w -> IO () Source Delete all items. Only valid for writeable items. itemAppend :: w -> a -> IO () Source Append an item. Only valid for writeable items.

Misc.

class Able w where Source

Widgets that can be enabled or disabled. Methods enabled :: Attr w Bool Source Enable, or disable, the widget. Instances Able ToolBarItem

class Help w where Source

Widgets with help text. Methods help :: Attr w String Source Short help text, normally displayed in the status bar or popup balloon. Instances Help ToolBarItem

class Tipped w where Source

Widgets that have a tooltip Methods tooltip :: Attr w String Source The tooltip information Instances Tipped ToolBarItem

class Identity w where Source

The identity determines the wxWindows ID of a widget. Methods identity :: Attr w Int Source The identity determines the wxWindows ID of a widget. Instances Identity ToolBarItem

class Styled w where Source

The style is a bitmask that determines various properties of a widget. Methods style :: Attr w Int Source The windows style.

class Framed w where Source

Widgets that have a system frame around them. Methods resizeable :: Attr w Bool Source Make the widget user resizeable? This attribute must be set at creation time. minimizeable :: Attr w Bool Source Can the widget be minimized? This attribute must be set at creation time. maximizeable :: Attr w Bool Source Can the widget be maximized? This attribute must be set at creation time and is normally used together with resizeable. closeable :: Attr w Bool Source Can the widget be closed by the user? This attribute must be set at creation time.

class Checkable w where Source

Checkable widgets Methods checkable :: Attr w Bool Source Is the widget checkable? checked :: Attr w Bool Source Is the widget checked? Instances Checkable ToolBarItem

class Dockable w where Source

Dockable widgets. Methods dockable :: Attr w Bool Source Is the widget dockable?

class Pictured w where Source

Widgets with a picture. Methods picture :: Attr w FilePath Source The image of a widget.

class Valued w where Source

Items with a value. Methods value :: Attr (w a) a Source The value of an object. Instances Valued IORef

class Sized w where Source

Sized objects (like bitmaps) Methods size :: Attr w Size Source The size of an object. (is outerSize for Dimensions widgets).
