小编Ser*_*pin的帖子

我有一个在GUI设计器的帮助下创建的项目.这是主要形式的代码.

public class MainForm {
    MainForm() {
        directLineOkButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent arg0) {
               //some action
                }
            }
        });
        crossLineOkButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent arg0) {
               //some action
        });
        clearButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent arg0) {
            //some action
        });
        cancelButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent arg0) {
            //some action
        });
        saveButton.addActionListener(new ActionListener() {
           public void actionPerformed(ActionEvent arg0) {
          //some action
        });
    }

    public JPanel getMainPanel() {
        return mainPanel;
    }

    private void createUIComponents() {
        drawingPanel = new DrawingPanel(); …

尝试登录但不能.我的tomcat-users.xml,正如我在这里看到的那样进行了修改.

    <?xml version="1.0" encoding="UTF-8"?>
   <tomcat-users>
      <role rolename="manager-gui"/>
      <role rolename="manager-script"/>
      <role rolename="manager-jmx"/>
      <role rolename="manager-status"/>
      <role rolename="admin-gui"/>
      <role rolename="admin-script"/>
      <user username="admin" password="admin" roles="manager-gui, manager-script, manager-jmx, manager-status, admin-gui, admin-script"/>
    </tomcat-users>

有什么建议？

我正在尝试d3.locale()在我的应用程序中显示几个月的俄语名称. http://jsfiddle.net/j2feJ/2/ 另外,我需要shortMonths变量是英文的,因为它们在我的数据库中是英文的.

var ru_RU = {
    "decimal": ",",
        "thousands": "\xa0",
        "grouping": [3],
        "currency": ["", " ???."],
        "dateTime": "%A, %e %B %Y ?. %X",
        "date": "%d.%m.%Y",
        "time": "%H:%M:%S",
        "periods": ["AM", "PM"],
        "days": ["???????????", "???????????", "???????", "?????", "???????", "???????", "???????"],
        "shortDays": ["??", "??", "??", "??", "??", "??", "??"],
        "months": ["??????", "???????", "????", "??????", "???", "????", "????", "??????", "????????", "???????", "??????", "???????"],
        "shortMonths": ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"]
}

但显示仍然是英文.我用错了吗？

我正在尝试在更改JTextField的文本后调用方法.

textField.getDocument().addDocumentListener(new DocumentListener()
        {

            public void changedUpdate(DocumentEvent arg0) 
            {
                System.out.println("IT WORKS");
                panel.setPrice(panel.countTotalPrice(TabPanel.this));
            }
            public void insertUpdate(DocumentEvent arg0) 
            {

            }

            public void removeUpdate(DocumentEvent arg0) 
            {

            }
        });

当我在另一个ActionListener上调用此方法时,它可以正常工作.但是当我在文本字段中更改文本时,没有任何反应.甚至印刷品.有什么建议？

我有一个d3.js的甜甜圈,我想在它的中心放一些信息.我可以追加文本元素,但我想在那里放一个格式化的信息,所以我决定在mouseover上添加div:

$(".arc").on("mouseover",(function(){
d3.select("text").remove();
var appendingString="<tspan>"+cityName[$(this).attr("id")]+"</tspan> <tspan>"+$(this).attr("id")+"%</tspan>";
group
.append("text")
.attr("x",-30)
.attr("y",-10)
.text(appendingString);
})); 

由于某种原因div成功添加了我需要但不显示的信息.追加它的正确方法是什么,还是有其他替代方法？完整脚本如果需要:

<script>
var cityNames=["?????????","???????","?????","???????"];
var cityPercentage=[50,30,20,10];
var width=300,
    height=300,
    radius=100;
var color=d3.scale.linear()
            .domain([0,60])
            .range(["red","blue"]);
var cityDivision = d3.select("#cities")
            .append("svg")
            .attr("width", width)
            .attr("height", height)
            .attr("class","span4");
var group=cityDivision.append("g")
.attr("transform","translate(" + width / 2 + "," + height / 2 + ")");
var arc=d3.svg.arc()
    .innerRadius(radius-19)
    .outerRadius(radius);
var pie= d3.layout.pie()
    .value(function(d){return d;});
var cityName={
    50:"?????????",
    30:"???????",
    20:"?????",
    10:"???????"
}
var arcs=group.selectAll(".arc")
    .data(pie(cityPercentage))
    .enter()
    .append("g")
    .attr("class","arc")
    .attr("id",function(d){return d.data;});
    arcs.append("path")
    .attr("d",arc)
    .attr("fill",function(d){return color(d.data);});
//?????????? …

我已经从这里下载了 yii2-grid-master

根据 readme.md 我已经在我的控制台中安装了 composer 和 din ：

php composer.phar require kartik-v/yii2-grid "@dev"

现在我尝试根据文档使用它。我把这个放在我的观点中：

use kartik\grid\GridView;
$gridColumns = [
    ['class' => 'kartik\grid\SerialColumn'],
    [
        'class' => 'kartik\grid\EditableColumn',
        'attribute' => 'name',
        'pageSummary' => 'Page Total',
        'vAlign'=>'middle',
        'headerOptions'=>['class'=>'kv-sticky-column'],
        'contentOptions'=>['class'=>'kv-sticky-column'],
        'editableOptions'=>['header'=>'Name', 'size'=>'md']
    ],
    [
        'attribute'=>'color',
        'value'=>function ($model, $key, $index, $widget) {
            return "<span class='badge' style='background-color: {$model->color}'> </span>  <code>" . 
                $model->color . '</code>';
        },
        'filterType'=>GridView::FILTER_COLOR,
        'vAlign'=>'middle',
        'format'=>'raw',
        'width'=>'150px',
        'noWrap'=>true
    ],
    [
        'class'=>'kartik\grid\BooleanColumn',
        'attribute'=>'status', 
        'vAlign'=>'middle',

我正在尝试使用 Maven 2 IDEA UI 设计器插件。我根据这篇文章编辑了 pom.xml：http : //glxn.net/2010/08/17/making-a-swing-project-using-intellij-idea-and-gui-builder-with-maven- include-executable-jar/ jar 文件创建正常，但是当我尝试运行它时，它说：线程“main”java.lang.NoClassDefFoundError 中的异常：

我试图在我的服务器上安装pecl_http根据手册手册是为ubuntu,但作为pecl http packadge apt-cache search pecl_http返回php5-pecl-http:

sudo apt-get update
sudo apt-get install php-pear php5-dev
sudo apt-get install php5-pecl-http
sudo apt-get install libcurl3-openssl-dev

在最后php.ini添加extension=http.so. http_get()和我需要的http_parse_headers()函数说func是未定义的.有什么问题？

我用twitter bootstrap制作了一个html页面,这里是结果页面的代码和截图.

我希望导航栏<li>元素更靠近div的左边界.我一直在尝试不同的css解决方案,如:

ul
{
    list-style:none;
    padding-left:0px;
    margin-left: 0px;
    background-color: red;
}

但是没有任何东西帮助过我.有什么建议？

我有一个简单的条形图：

var margin = {top: 20, right: 20, bottom: 30, left: 50};
var xLPU=d3.scale.ordinal();
var yLPU=d3.scale.linear();
var xLPUAxis = d3.svg.axis()
    .scale(xLPU)
    .orient("bottom");

var yLPUAxis = d3.svg.axis()
    .scale(yLPU)
    .orient("left")
    .ticks(10, "???.");
var LPUdivision=d3.select("#LPUgraph").append("svg")
    .attr("width", width + margin.left + margin.right)
    .attr("height", height + margin.top + margin.bottom)
  .append("g")
    .attr("transform", "translate(" + margin.left + "," + margin.top + ")");
