i add new record listview's itemssource collection: source.add(newrecord); after action i'm trying rectangle of corresponding item: listviewitem newitem = list.itemcontainergenerator.containerfromitem(newrecord) listviewitem; rect rc = layoutinformation.getlayoutslot(newitem); but, unfortunately, rc (0, 0, 0, 0). seems when call getlayoutslot method, new listviewitem not yet arranged. how can obtain correct information directly after adding new record? any appreciated. calling list.updatelayout(); before line listviewitem newitem = ... should rectangle immediately. but generally, not recommend use updatelayout() anywhere in wpf program. layout procedures in wpf asynchronous performance reasons. therefore, better if program determined rectangles of list items @ later point in time. here mean "later point in time": source.add(newrecord); dispatcher.begininvoke(dispatcherpriority.loaded, new action(() => { listviewitem...

this appears quite simple have no idea how go it. dataframe looks this: var1 var2 var3 var4 var5 var6 ..... var57 1 23 67 89 63 34 ..... 90 2 34 43 43 23 23 ..... 32 3 45 65 45 32 54 ..... 43 4 45 32 18 61 87 ..... 39 5 23 74 53 54 76 ..... 54 6 21 65 34 34 12 ..... 97 . . . . . . ..... . . . . . . . ..... . . . . . . . ..... . 365 54 78 54 12 90 ..... 53 i want produce separate plots , save them in working directory var1 against variables. plot(var1 ~ var2) plot(var1 ~ var3) plot(var1 ~ var4) plot(var1 ~ var5) . . . . . plot(var1 ~ var57) is there way automate dont have produce each individual plots @ time , save in working directory? thanks lot. pdf("plots.pdf") for(i in 2:ncol(df)) plot(df[,1] ~ df[,i]) dev.off()

sorry misleading title, pretty hard describe problem in few words. basically want when hover on caption want headline block text underline. right have jsfiddle on every other caption 1 hovering. jsfiddle: http://jsfiddle.net/gnfpj/1/ css: .caption { width: 480px; height: 270px; float: left; margin-left: 5px; margin-top: 5px; } .caption p { background-color: #000; color: #fff; margin-top: -53px; height: 50px; padding: 7px; -moz-box-sizing: border-box; -webkit-box-sizing: border-box; box-sizing: border-box; opacity: 0.7; font-family: verdana, sans-serif; font-size: 12px; line-height: 19px; } .caption p span { font-weight: bold; font-size: 14px; } .caption:hover ~ .caption p span { text-decoration: underline; } .caption { text-decoration: none; } you want simple descending selector: .caption:hover p span { text-decoration: underline; } http://jsfiddle.net/gnfpj/2/
