透明 oclock に秒針とjewel を拡充

透明であまり邪魔にならないので, oclock -transparent を常用しています. これに, 秒針と文字盤の5分毎の刻目(jewel) が欲しいと思って作ったパッチ. 例によって, かなり場当り的.

僕のマシンでは,

.fvwmrc で Style "oclock" StaysOnTop, Sticky, WindowListSkip
.xinitrc で oclock -transparent -geometry 80x80+300+0 &

として, いつもいつも見えるようになってます.

X のソ－スの programs 以下は X のプログラミングのサンプル的な意味もあるので, 改造して遊びましょう.

手順

後にある oclock.patch ファイルを作っておく.
X11R6 のソ－スを展開して xc/programs/oclock に cd する
patch < oclock.patch
xmkmf; make
./oclock -transparent で出来具合を見よう
