问题 We have numerical values in our database, representing a two-value-state. Of course this would perfectly match a boolean, but oracle has no such datatype. The NUMBER(1,0) type from the database is matched to a java.lang.Short type in Java (sometimes they used a NUMBER(*,0) to represent booleans, which are matched to java.math.BigDecimal). Since it is somehow obvious, I want to offer ice:selectBooleanCheckbox in the view as a value representation and UIComponent to the user. (I use IceFaces as

问题 I have a JFreeChart that has several different lines plotted on it. I need to change some of the lines to step lines. I know I need to use the CategoryStepRenderer but am having trouble implementing it. I attached the following code that I use to change the color of the lines. I would like to be able to do the step line in a similar way. All of the ways I have found involve changing all of the lines. Thanks private void updateChartColor(ArrayList mlColor,ArrayList mlLine){ XYPlot plot=(XYPlot

问题 Is there a way to setup the Three.js renderer in such a way that the lookat point of the camera is not in the center of the rendered image? To clarify: image a scene with just one 1x1x1m cube at ( 0, 0, 0 ). The camera is located at ( 0, 0, 10 ) and the lookat point is at the origin, coinciding with the center of the cube. If I render this scene as is, I might end up with something like this: normal render However I'd like to be able to render this scene in such a way that the lookat point is

问题 There is a common method when using JTable TableCellRenderers for setting the background and foreground when the cell is selected. Here is an example question that was asked: Why does my Java custom cell renderer not show highlighting when the row/cell is selected? This solution is lacking one thing ... the border around the cell. (Note I am not asking about a border around the row, as was asked here.) The border should highlight when the cell is selected. It is not acceptable to just create

问题 I have 3D object and I want to make it invisible by turning off its rendering . But when I run the code in runtime it shows :: " Exception in callback: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> UnityEngine.MissingComponentException: There is no 'Renderer' attached to the "3dObject" game object, but a script is trying to access it. " I want to know if There is no renderer then how I am able to see that object in scene/game view.

问题 I have two JTable . There are certain number of records in one JTable . Once the first JTable is loaded I want to load equal number of JCheckbox to be created in the second table. I have this scenario ... vl pass both the tables in method addCheckBox . private void addCheckBox(JTable procTableSrc, JTable procTableCk){ CheckBoxRenderer checkBoxRenderer = new CheckBoxRenderer(); EachRowRenderer rowRenderer = new EachRowRenderer(); int rows = procTableSrc.getRowCount(); DefaultTableModel dm =

问题 I want the ability to highlight some rows of JTable , depending on the values in the row itself. For example, if the existing qty < reorder level , that row should be highlighted in the JTable . I know there is a table method tblItems.setSelectionBackground(Color.yellow); that works when the rows are selected, but is there a similar method that doesn't rely on the rows being selected to have them show in a different color? public class MyTableCellRenderer implements TableCellRenderer {

问题 Please have a look at the SSCCE. How can I make the non-selected tree nodes' background transparent. At the moment the background of non-selected nodes is white. My cell renderer, however, should paint it non-opaque if it is not selected (and green when selected...what it does). In the end I want non-selected nodes to be just text without background, since the area which is red in the SSCCE has a gradient fill in my application. import java.awt.BorderLayout; import java.awt.Color; import java

问题 I have been working to transition a Java application from WindowsLookAndFeel to Nimbus, largely successfully, despite Nimbus foibles. My users overall like the Nimbus LaF but didn't like some details, some of which I changed by consulting previous questions on this site. Example: I copied the LeafIcon, ClosedIcon and OpenIcon from Windows LaF (which they liked) and use them in the Nimbus version, for a nice combination of LaFs. Stuck on one last (?) problem. I have a JTree with a subclassed

问题 I've got a custom will_paginate renderer that overrides WillPaginate::ViewHelpers::LinkRenderer's link method like so: def link(text, target, attributes = {}) "<a href='/users/95/friends_widget?page=#{target}' rel='next' data-remote='true'>#{text}</a>" end ...and that works great, except you can see the hard-coded 95 in that link. How would I pass a parameter (e.g. user or user's ID) into the custom renderer via the Rails view? <%= will_paginate(@user_friends, :remote => true, :renderer =>
