Description

Base class for widgets with two adjustable panes

Synopsis

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 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.

Types

Methods

panedAdd1Source

Arguments

:: (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.

panedAdd2Source

Arguments

:: (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.

panedPack1Source

Arguments

:: (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.

panedPack2Source

Arguments

:: (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.

panedSetPositionSource

Arguments

:: 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.

panedGetPositionSource

Arguments

:: PanedClass self 
=> self 
-> IO Int

returns position of the divider

Obtains the position of the divider between the two panes.

panedGetChild1Source

Arguments

:: 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

panedGetChild2Source

Arguments

:: 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

panedGetHandleWindow :: PanedClass self => self -> IO DrawWindowSource

Returns the Window of the handle. This function is useful when handling button or motion events because it enables the callback to distinguish between the window of the paned, a child and the handle.

Attributes

panedPosition :: PanedClass self => Attr self IntSource

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 BoolSource

True if the Position property should be used.

Default value: False

panedMinPosition :: PanedClass self => ReadAttr self IntSource

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 IntSource

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 BoolSource

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 BoolSource

The "shrink" child property determines whether the child can be made smaller than its requisition.

Default value: True
