gtkButtonBoxSetChildSecondary {RGtk2} | R Documentation

## gtkButtonBoxSetChildSecondary

### Description

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.

### Usage

    gtkButtonBoxSetChildSecondary(object, child, is.secondary)

### Arguments

``object`` | a `GtkButtonBox`
``child`` | a child of `widget`
``is.secondary`` | if `TRUE`, the `child` appears in a secondary group of the button box.

### Details

This group appears after the other children if the style is `GTK_BUTTONBOX_START`, `GTK_BUTTONBOX_SPREAD` or `GTK_BUTTONBOX_EDGE`, and before 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 `gtkWidgetSetDirection`). 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.
