NAME

The Button Box widget

SYNOPSIS

#include <Xm/ButtonBox.h>

DESCRIPTION

                                                                 

The Button Box widget manages children (usually buttons) in a single row or single column layout.

The Button Box maintains equal spacing between its children at all times and attempts to adjust its height and width as necessary so that all children will fit. If this is not possible, due to parent or application programmer constraints, the Button Box will resize its children as necessary to fit within the available space.

Note: in what follows, major direction refers to the direction of orientation, and minor direction refers to the perpendicular direction.

Normal Resources

Name Class Type Initial Value
equalSize EqualSize Boolean False
fillOption FillOption unsigned char XmFillNone
marginHeight Margin VerticalDimension 0
marginWidth Margin HorizontalDimension 0
orientation Orientation unsigned char XmHORIZONTAL

All resource names begin with XmN and all resource class names begin with XmC.

equalSize

Specifies whether the children are to be maintained with equal sized heights and widths. The chosen height and width for the children is found by asking each child for its preferred size and taking the largest value in each direction.

fillOption

Specifies how to use any extra space left over once all children have been sized according to either their preference or equalSize. There are four options:

XmFillNone      

No automatic filling is performed. Center the children in the minor direction and
place the children with equal padding between them in the major direction.

XmFillMinor

Place the children with equal padding between them in the major direction, but force all the children to take on the Button Box minor dimension as their minor direction.

XmFillMajor

Center the children in the minor direction, but expand all the children in their major direction so that there is no padding between them. Expand the children such that their relative sizes remain constant.

XmFillAll

This option combines the placement actions and sizing actions of XmFillMinor and XmFillMajor.

Regardless of the fill mode, the ButtonBox widget will always leave the specified margin between its edge and the nearest child. A new String to fillOption resource converter has been registered to convert the following strings to fill options: "none", "major", "minor", "all." This resource can therefore be set in an application defaults file.

marginHeight

marginWidth

Specifies the number of pixels to use as a margin around the entire group of children. The marginHeight value applies to both the top and bottom margins, while the marginWidth applies to the left and right margins.

orientation

Specifies whether children are to be placed in a row or a column. The orientation may be either XmHORIZONTAL or XmVERTICAL. If the orientation is XmHORIZONTAL, the children are placed in a row with the major dimension being width and the minor dimension being height. If the value is XmVERTICAL, the children are placed in a column with the major dimension being height and the minor dimension being width. The default value is XmHORIZONTAL.

Translations and Actions:

The Button Box manager inherits all of its translations and actions from its superclass.
