|
|
| data Color |

|
| newGCValues :: GCValues |
|
| widgetGetState :: WidgetClass w => w -> IO StateType |
Retrieve the current state of the widget.
- The state refers to different modes of user interaction, see
StateType for more information.
|
|
| widgetGetSavedState :: WidgetClass w => w -> IO StateType |
Retrieve the current state of the widget.
- If a widget is turned insensitive, the previous state is stored in
a specific location. This function retrieves this previous state.
|
|
| type Allocation = Rectangle |

- The upper part of a dialog window consists of a VBox.
Add the required widgets into this box.
|
|
| dialogGetActionArea :: DialogClass dc => dc -> IO HBox |
Extract the action area of a dialog box.
- This
is useful to add some special widgets that cannot be added with
dialogAddActionWidget.
|
|
| fileSelectionGetButtons :: FileSelectionClass fsel => fsel -> IO (Button, Button) |
| Extract the buttons of a fileselection.
|
|
| data ResponseId |
| Some constructors that can be used as response
numbers for dialogs.
| | Constructors | | ResponseNone | GTK returns this if a response widget has no response_id,
or if the dialog gets programmatically hidden or destroyed.
| | ResponseReject | GTK won't return these unless you pass them in as
the response for an action widget. They are for your convenience.
| | ResponseAccept | (as above)
| | ResponseDeleteEvent | If the dialog is deleted.
| | ResponseOk | "Ok" was pressed.
- This value is returned from the "Ok" stock dialog button.
| | ResponseCancel | "Cancel" was pressed.
- These value is returned from the "Cancel" stock dialog button.
| | ResponseClose | "Close" was pressed.
- This value is returned from the "Close" stock dialog button.
| | ResponseYes | "Yes" was pressed.
- This value is returned from the "Yes" stock dialog button.
| | ResponseNo | "No" was pressed.
- This value is returned from the "No" stock dialog button.
| | ResponseApply | "Apply" was pressed.
- This value is returned from the "Apply" stock dialog button.
| | ResponseHelp | "Help" was pressed.
- This value is returned from the "Help" stock dialog button.
| | ResponseUser Int | A user-defined response
- This value is returned from a user defined button

|
| type IconSize = Int |
| The size of an icon in pixels.
|
|
| iconSizeInvalid :: IconSize |
| Don't scale but use any of the available sizes.
|
|
| iconSizeMenu :: IconSize |
| Icon size to use in next to menu items in drop-down menus.
|
|
| iconSizeSmallToolbar :: IconSize |
| Icon size for small toolbars.
|
|

| Icon size for larger toolbars.
|
|
| iconSizeButton :: IconSize |
| Icon size for icons in buttons, next to the label.
|
|
| iconSizeDialog :: IconSize |

|
|
| comboGetList :: Combo -> IO List |
| Extract the List container from a Combo box.
|
|
| widgetGetDrawWindow :: WidgetClass widget => widget -> IO DrawWindow |
Retrieves the DrawWindow that the widget draws onto.
This may be Nothing if the widget has not yet been realized, since a
widget does not allocate its window resources until just before it is
displayed on the screen. You can use the
onRealize signal to give you the
opportunity to use a widget's DrawWindow as soon as it has been created
but before the widget is displayed.
|
|
| widgetGetSize :: WidgetClass widget => widget -> IO (Int, Int) |
Returns the current size.
- This information may be out of date if the user is resizing the window.
|
|
| layoutGetDrawWindow :: Layout -> IO DrawWindow |
| Retrieves the Drawable part.
|
|
| pangoScale :: Double |
|
| data PangoDirection |
The PangoDirection type represents a direction in the Unicode
bidirectional algorithm.
- The "weak" values denote a left-to-right or right-to-left direction
only if there is no character with a strong direction in a paragraph.
An example is a sequence of special, graphical characters which are
neutral with respect to their rendering direction. A fresh
PangoContext is by default weakly
left-to-right.
- Not every value in this enumeration makes sense for every usage
of PangoDirection; for example, the return value of
unicharDirection and findBaseDir cannot be PangoDirectionWeakLtr
or PangoDirectionWeakRtl, since every character is either neutral or
has a strong direction; on the other hand PangoDirectionNeutral
doesn't make sense to pass to log2visGetEmbeddingLevels.
| | Constructors | | PangoDirectionLtr | | | PangoDirectionRtl | | | PangoDirectionWeakLtr | | | PangoDirectionWeakRtl | | | PangoDirectionNeutral | |

|
|
| styleGetAntiAliasing :: Style -> StateType -> IO Color |
Retrieve the color for drawing anti-aliased text.
- The anti-aliasing color is the color which is used when the rendering
of a character does not make it clear if a certain pixel shoud be set
or not. This color is between the text and the base color.
