问题 I'm looking for a highly efficient Swing Java component which I can just plug into my application UI. I already tried using the classes within Swing such as JTextArea with no avail; they simply aren't high-performance enough and have any crippling drawbacks. Additionally, it'd be nice if it had standard console features such as scroll-lock, clear console, colours, and so on. Edit: Forgot to say, this console will have a lot of debug information streaming into it, and it needs to be fully

问题 I've tried many stackoverflow options like Load existing components dynamically Angular 2 Final Release.

Now i need a new solution. Who can help me out? page.component.ts import { Component, ViewChild

问题 I'm working on some components in XE2. Is it possible to have more than the component's unit added to the uses clause of the form it's dropped on?

问题 What is a component class and where would I typically use one? When I add a new item to my project in VS.NET 2008 one of the options is to add a component. I am not even sure I understand what a component is - but I would sure like to find out a bit more about them. Could somebody explain them to me or perhaps point me towards an online tutorial that would help me. 回答1: Well, generally speaking, a component is any part of a thing. Specifically in .NET, a component is a class that implements

问题 This is getting on my nerves and it probably something silly on my part but I can't figure out why my paintComponent is being called twice, if you run my code it outputs REPEAT? REPEAT? twice, I don't want it to do that.. So why does it do it and how can I fix it? import java.util.Random; import javax.swing.JFrame; import javax.swing.JPanel; import java.awt.*; public class Main extends JPanel { public Main() { /*code here*/ } public void paintComponent(Graphics page) { clear(page); /*code

问题 I start to build an application. There are a lot of components. Each of them need a part of data from 1 webSocket. The example of a receiveing object by webSocket: Each Angular 2 component need 1 field from receiveing object. Is it possible to make 1 service, that will connect to webSocket, receive data and share it between all components ? I think it will be a good solution. Now i'm using the next approach: getConfigCallback() { this.connectionSockets.telemetry = io(this.config.connections
