label

问题 I am trying to get a random bunch of pictures to print side by side; the problem is that if I run the following code all that happens is that it creates a group of blank empty labels. If I replace the 'image=pic' with a "text='whatever'" it works fine (thus proving that it dows actually create the label). Placing the label and image anywhere else works fine (proving that it's not the images), even if I use 'pic = PhotoImage(file=w[0])' it works (so I don't think its my method)... from tkinter

问题 I'm using d3 v4. I want to move tabels out of my pie chart and have them point at the pie chart instead (because for small wedges it is not possible to read the labels). I thought this would add external labels // Now we'll draw our label lines, etc. enteringLabels = labels.selectAll(".label").data(data).enter(); labelGroups = enteringLabels.append("g").attr("class", "label"); labelGroups.append("circle").attr({ x: 0, y: 0, r: 2, fill: "#000", transform: function (d, i) { centroid = pied_arc

问题 Is there any way to have a label respond to focus. I have some code where the textfield has a different style on focus. The label also however needs a slightly different style. I tried this but it did not effect the label. #header .search label { background:url(http://www.golfbrowser.com/images/icons/search.png) left top no-repeat; padding-left:20px; height:20px; float:right; } #header .search label:focus { background:url(http://www.golfbrowser.com/images/icons/search-z.png) left top no

问题 How can I display values for my stacked barh chart that come from a dataframe? How can I place the labels above their respective sections on each bar and modify the font so that it shows up well as a gray scale graphic? It is related to this question but it has a list of values rather than two lists pulled from a pandas dataframe. If it were a singe list, I think I could pull values from a single record in the dataframe but with two lists, I'm not sure how to apply that to each bar in the bar

问题 I ave tried the following code: Label label = new Label(reallyLongString, skin); label.setWrap(true); label.setWidth(100); // or even as low as 10 table.add(label); ... and yet all I get is a very wide line that draws off the screen. How to get a Label with wrapped text? 回答1: This is the same issue as seen in slider always has default width or "Slider always has default width". You need to put that label into a table and add the right size to the cell of the table where the label is. UI

问题 This question already has answers here : Please explain the usage of Labeled Statements (3 answers) Closed 4 years ago . I'm busy studying for my certification and I stumbled upon a concept I've never even heard before - "Labeled Statements". e.g: 'label' : 'statement' L1: while(i < 0){ L2: System.out.println(i); } So my question is.. why? How is this useful and when would one want to use something like this? 回答1: The only use that I'm aware of is that you can use labels in break or continue

问题 I'm trying to produce a plot where I have the character Å (angstroms) in the x axis. Moreover, I want this character to be in the same font as the rest of the graph, that is I want to use Times-Roman. If I use the following code: set encoding iso_8859_1 set term postscript eps enhanced color "Times-Roman, 32" set output "angstroms.eps" set xlabel "Try1 {A} ({\305})" plot sin(x) I obtain this figure: (note: the figure I get is in eps format, but I have to upload a jpg to stackoverflow) If I

问题 Sometimes a labeled break or continue can make code a lot more readable. OUTERLOOP: for ( ;/*stuff*/; ) { //...lots of code if ( isEnough() ) break OUTERLOOP; //...more code } I was wondering what the common convention for the labels was. All caps? first cap? 回答1: If you have to use them use capitals, this draws attention to them and singles them out from being mistakenly interpreted as "Class" names. Drawing attention to them has the additional benefit of catching someone's eye that will

问题 I have a table in a page that consists of checkboxes in the cells on the left and descriptions in the cells on the right. The "description" contains h4 headers and plain text. I want to make that whole description (everything inside <td></td> ) a label. So each row looks like this: <tr><td><input type="checkbox" name="entiries[]" value="i1" id="i1"></td> <td><label for="i1"> <h4>Some stuff</h4>more stuff.. <h4>Some stuff</h4>more stuff.. </label> </td></tr> This does not work however, the
