Graphics.UI.Gtk.Abstract.ButtonBox

Base class for HButtonBox and VButtonBox

Detail

The primary purpose of this class is to keep track of the various properties of HButtonBox and VButtonBox widgets.

buttonBoxGetChildSize retrieves the minimum width and height for widgets in a given button box. buttonBoxSetChildSize allows those properties to be changed.

The internal padding of buttons can be retrieved and changed per button box using buttonBoxGetChildIpadding and buttonBoxSetChildIpadding respectively.

buttonBoxGetSpacing and buttonBoxSetSpacing retrieve and change default number of pixels between buttons, respectively.

buttonBoxGetLayout and buttonBoxSetLayout retrieve and alter the method used to spread the buttons in a button box across the container, respectively.

The main purpose of ButtonBox is to make sure the children have all the same size. Therefore it ignores the homogeneous property which it inherited from Box, and always behaves as if homogeneous was True.

Methods

buttonBoxGetLayout :: ButtonBoxClass self => self -> IO ButtonBoxStyle

Retrieves the method being used to arrange the buttons in the button box.

buttonBoxSetLayout

Arguments

:: ButtonBoxClass self

=> self

-> ButtonBoxStyle

layoutStyle - the new layout style.

-> IO ()

Changes the way buttons are arranged in their container.

buttonBoxSetChildSecondary

Arguments

:: (ButtonBoxClass self, WidgetClass child)

=> self

-> child

child - a child of the button box widget

-> Bool

isSecondary - if True, the child appears in a secondary group of the button box.

-> IO ()

Sets whether child should appear in a secondary group of children. A typical use of a secondary child is the help button in a dialog.

This group appears after the other children if the style is ButtonboxStart, ButtonboxSpread or ButtonboxEdge, and before the other children if the style is ButtonboxEnd. For horizontal button boxes, the definition of before/after depends on direction of the widget (see widgetSetDirection). If the style is ButtonboxStart or ButtonboxEnd, then the secondary children are aligned at the other end of the button box from the main children. For the other styles, they appear immediately next to the main children.

buttonBoxGetChildSecondary

Arguments

:: (ButtonBoxClass self, WidgetClass child)

=> self

-> child

child - a child of the button box widget

-> IO Bool

returns whether child should appear in a secondary group of children.

Returns whether child should appear in a secondary group of children.

• Available since Gtk+ version 2.4
