Detail
`Paned` is the base class for widgets with two panes, arranged either horizontally (`HPaned`) or vertically (`VPaned`). Child widgets are added to the panes of the widget with `panedPack1` and `panedPack2`. The division beween the two children is set by default from the size requests of the children, but it can be adjusted by the user. A paned widget draws a separator between the two child widgets and a small handle that the user can drag to adjust the division. It does not draw any relief around the children or around the separator. (The space in which the separator is called the gutter.) Often, it is useful to put each child inside a `Frame` with the shadow type set to Graphics.UI.Gtk.General.Enums.ShadowIn so that the gutter appears as a ridge. Each child has two options that can be set, `resize` and `shrink`. If `resize` is true, then when the `Paned` is resized, that child will expand or shrink along with the paned widget. If `shrink` is true, then when that child can be made smaller than its requisition by the user. Setting `shrink` to `False` allows the application to set a minimum size. If `resize` is false for both children, then this is treated as if `resize` is true for both children. The application can set the position of the slider as if it were set by the user, by calling `panedSetPosition`.

Methods
panedAdd1
:: (PanedClass self, WidgetClass child) |
=> self |
-> child | `child` - the child to add
-> IO () |
Adds a child to the top or left pane with default parameters. This is equivalent to ``panedPack1` paned child False True`.
panedAdd2
:: (PanedClass self, WidgetClass child) |
=> self |
-> child | `child` - the child to add
-> IO () |
Adds a child to the bottom or right pane with default parameters. This is equivalent to ``panedPack2` paned child True True`.
panedPack1
:: (PanedClass self, WidgetClass child) |
=> self |
-> child | `child` - the child to add
-> Bool | `resize` - should this child expand when the paned widget is resized.
-> Bool | `shrink` - can this child be made smaller than its requsition.
-> IO () |
Adds a child to the top or left pane.
panedPack2
:: (PanedClass self, WidgetClass child) |
=> self |
-> child | `child` - the child to add
-> Bool | `resize` - should this child expand when the paned widget is resized.
-> Bool | `shrink` - can this child be made smaller than its requsition.
-> IO () |
Adds a child to the bottom or right pane.
panedSetPosition
:: PanedClass self |
=> self |
-> Int | `position` - pixel position of divider, a negative value means that the position is unset.
-> IO () |
Sets the position of the divider between the two panes.
panedGetPosition
:: PanedClass self |
=> self |
-> IO Int | returns position of the divider
Obtains the position of the divider between the two panes.
panedGetChild1
:: PanedClass self |
=> self |
-> IO (Maybe Widget) | returns first child, or `Nothing` if it is not set.
Obtains the first child of the paned widget. Available since Gtk+ version 2.4
panedGetChild2
:: PanedClass self |
=> self |
-> IO (Maybe Widget) | returns second child, or `Nothing` if it is not set.
Obtains the second child of the paned widget. Available since Gtk+ version 2.4
Attributes
panedPosition :: PanedClass self => Attr self Int
Position of paned separator in pixels (0 means all the way to the left/top). Allowed values: >= 0 Default value: 0
panedPositionSet :: PanedClass self => Attr self Bool
`True` if the Position property should be used. Default value: `False`
panedMinPosition :: PanedClass self => ReadAttr self Int
The smallest possible value for the position property. This property is derived from the size and shrinkability of the widget's children. Allowed values: >= 0 Default value: 0
panedMaxPosition :: PanedClass self => ReadAttr self Int
The largest possible value for the position property. This property is derived from the size and shrinkability of the widget's children. Allowed values: >= 0 Default value: 2147483647
Child Attributes
panedChildResize :: (PanedClass self, WidgetClass child) => child -> Attr self Bool
The "resize" child property determines whether the child expands and shrinks along with the paned widget. Default value: `True`
panedChildShrink :: (PanedClass self, WidgetClass child) => child -> Attr self Bool
The "shrink" child property determines whether the child can be made smaller than its requisition. Default value: `True`
