### NAME

lower — 窓の積重ね順を変える Change a window's position in the stacking order

### 構文 SYNOPSIS

lower window ?belowThis?

### 説明 DESCRIPTION

もし belowThis 引数が省略されると､この命令は window を下げ､その結果全ての兄弟より棚順が低くなる(重なっているどの兄弟にも覆われ､どの兄弟も覆うことはない)｡もし belowThis が指定されるとそれは窓の経路名でなくてはならず､ window の兄弟か window の兄弟の子孫である｡この場合､ lower 命令は window を丁度 window (又は､belowThis の祖先つまり window の兄弟)の下の順に挿入する; これは window を上げるか下げることになるかもしれない｡ If the belowThis argument is omitted then the command lowers window so that it is below all of its siblings in the stacking order (it will be obscured by any siblings that overlap it and will not obscure any siblings). If belowThis is specified then it must be the path name of a window that is either a sibling of window or the descendant of a sibling of window. In this case the lower command will insert window into the stacking order just below belowThis (or the ancestor of belowThis that is a sibling of window); this could end up either raising or lowering window.

全ての頂上水準toplevelの窓は互いを考慮して､その相対経路名がどんなであっても､再積み重ねされることがあるが､窓管理譜は再積重ねする要求を厳密には尊重する義務はない｡ All toplevel windows may be restacked with respect to each other, whatever their relative path names, but the window manager is not obligated to strictly honor requests to restack.
