Description

A button box is used to provide a consistent layout of buttons throughout an application. The gtk.ButtonBox is subclassed by the gtk.HButtonBox and gtk.VButtonBox classes to provide horizontal and vertical button layouts respectively. The same effect could be achieved by using a gtk.Box but less conveniently.

A buttonbox provides one default layout and a default spacing value that are persistent across all widgets. The layout/spacing can then be altered by the programmer, or if desired, by the user to alter the 'feel' of a program to a small degree.

The gtk.Box.get_spacing() method and the gtk.Box.set_spacing() methods retrieve and change the default number of pixels between buttons. The get_layout() and set_layout() methods retrieve and alter the style used to spread the buttons in a button box across the container. The layout styles are: gtk.BUTTONBOX_SPREAD, gtk.BUTTONBOX_EDGE, gtk.BUTTONBOX_START and gtk.BUTTONBOX_END.

Methods

gtk.ButtonBox.get_layout

    def get_layout()

Returns :

the layout style used by the buttonbox

The get_layout() method returns the current value of the "layout-style" property. The possible values are: gtk.BUTTONBOX_SPREAD, gtk.BUTTONBOX_EDGE, gtk.BUTTONBOX_START and gtk.BUTTONBOX_END.

gtk.ButtonBox.set_layout

    def set_layout(layout_style)

layout_style :

the new layout style

The set_layout() method sets the "layout-style" property to the value in layout_style. The possible values are: gtk.BUTTONBOX_SPREAD, gtk.BUTTONBOX_EDGE, gtk.BUTTONBOX_START and gtk.BUTTONBOX_END.

gtk.ButtonBox.get_child_secondary

    def get_child_secondary(child)

child :

a child button of the buttonbox

Returns :

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

Note

This method is available in PyGTK 2.4 and above.

The get_child_secondary() method returns True if child should appear in a secondary group of children. See the set_child_secondary() method for more information.

gtk.ButtonBox.set_child_secondary

    def set_child_secondary(child, is_secondary)

child :

a child button of the buttonbox

is_secondary :

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

The set_child_secondary() method sets whether child should appear in a secondary group of children. The typical use of a secondary child is the help button in a dialog that is displayed away from the main group of buttons e.g. right aligned.

The secondary group appears after the other children if the style is gtk.BUTTONBOX_START, gtk.BUTTONBOX_SPREAD or gtk.BUTTONBOX_EDGE, and before the the other children if the style is gtk.BUTTONBOX_END. For horizontal button boxes, the definition of before/after depends on direction of the widget (see gtk.Widget.set_direction()). If the style is gtk.BUTTONBOX_START or gtk.BUTTONBOX_END, 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.
