问题 I'm trying to apply the non-standard, but pretty widely supported CSS pseudo-selector for setting the text color of selections in the browser. All seemed to be fine at first, and then the ice weasels came. Let's say you have this HTML: <div class="outside"> So what's wrong with this picture? <div class="fancy"> Custom selection color lost on right <div>But only on direct children</div> <div>Divs underneath are ok (?)</div> </div> ...aaand selection bleeds to outside div. :-/ </div> With this

问题 My custom component is composed of three JTree s inside a JPanel . Only one JTree should be selected at a time, so I've added a TreeSelectionListener to each of them that calls clearSelection() on the previously selected JTree . (See here for more details). That works fine, but I need to prevent the TreeSelectionListener s to trigger when a JTree is deselected . A simple way to distinguish a selection event from a deselection one would be more than enough. Thanks in advance! 回答1: Just get the

问题 This topic has probably been brought up and it is a quite simpe solution , i guess. However i couldnt make it up to now. Lets say i have a data.frame (called "data") which contains 10 individuals (id) on which i collected observations at 3 time points (T) > data <- data.frame(id = rep(c(1:10), 3), T = gl(3, 10), X = sample(1:30), Y = sample(c("yes", "no"), 30, replace = TRUE), Z = sample(1:40, 30), Z2 = rnorm(30, mean = 5, sd = 0.5)) > head(data) id T X Y Z Z2 1 1 1 10 yes 15 5.993605 2 2 1

问题 This is one of the things that really annoys me in R. Consider the following example: a=data.frame(x=c(1,2),y=c(3,4)) i=which(a$x==0) At this point, i is "integer(0)" and length(i) is 0. Now if I do: b=a[-i,] Because I'm deleting by an empty index, I expect b to have all the data in a. But instead b is an empty data frame. I have to do this instead: if (length(i)>0) b=a[-i,] else b=a The same applies to matrices too. Is there a way to delete that handles empty index correctly without the if

Private Sub CommandButton1_Click() Dim rng As Word.Range Dim cl As Word.Cell Dim i As Integer, iRng As Word.Range Dim oWords As Words Dim oWord As Range If Selection.Information(wdWithInTable) = True Then For Each cl In Selection.Cells Set rng =

Also a screenshot of the selection: I can extend this selection to contain the whole 'a' element with the following code snippet (using Rangy library http://code.google.com/p/rangy/): $('body').on('mouseup', '[contenteditable]', function() { var block = this, sel = rangy.getSelection(), range = sel.getRangeAt(0); if (sel.anchorNode.parentNode !
