Here is the source public class TableHandler extends TransferHandler { private static final long serialVersionUID = 1L; @Override public boolean canImport(TransferSupport

ActionListener for JLabel

由 蓝咒 提交于 2019-12-18 03:40:26
问题 I want to learn how to write an ActionListener for JLabel . I want to make a label that open a new frame for user when user clicks the label. Maybe MouseListener can work but I do not know how to make it. 回答1: I recommend using a JTextField rather than a JLabel for this use. Being based on a component designed to be focusable, it allows an ActionListener and looks and feels more like an HTML link. E.G. That is how it appears when the mouse is hovering over the first link. LinkLabel /* License

问题 Here is the code I have written: super("Add contact"); setLayout(new FlowLayout()); IPAddress = new JLabel("IP Address"); IPAddress.setLocation(1000, 100); ImageIcon ii=new ImageIcon(getClass().getResource("Add.png")); JLabel image = new JLabel(ii); image.setSize(100, 100); image.setLocation(500, 100); add(image); add(IPAddress); setSize(500,150); } 回答1: That is correct. The layout manager is responsible for setting the location of a component based on the rules of the layout manager. So in

Asking for some clarification in java about jlabel and parent

由 假如想象 提交于 2019-12-17 20:33:59
问题 Found this code in the internet, it was posted years ago, so I just decided to ask here for some clarifications for some lines I don't quite understand. In the mousePressed method, what does he mean by: chessPiece = null is he saying that if the JLabel chessPiece has a image in it then it should be changed to null ? Is chessBoard.findComponentAt(e.getX(), e.getY()) returns the JPanel square? and lastly, when Component c gets its parent, who is the parent? The whole code is below: public class

JLabel with multiple lines and alignment to the right

由 我的未来我决定 提交于 2019-12-17 16:59:15
问题 I searched through many posts and figured out that JLabel supports HTML. So I can do JLabel search = new JLabel("<html>Search<br/> By:</html>"); to get multiple lines. Above code will result in Search By: However, What I want is something like Search By: Adding spaces before "By:" will work only when the window is not resizable(And very silly lol). Can anyone tell me how to modify this code to make it work as I wanted? 回答1: Slightly simpler HTML than seen in @MadProgrammer's answer: new

How to convert Icon from JLabel into BufferedImage?

由 早过忘川 提交于 2019-12-17 16:49:08
问题 Simple, very straight forward but seems uncle google and me getting confused. I have single JLabel that already has its own Icon . How do I convert the Icon obtained from JLabel into a BufferedImage ? Is there any way around: I tried to multiple casting like this .. final BufferedImage bf1 = (BufferedImage)((Image)jll_img.getIcon()); ..but it failed. 回答1: To amplify on @Andrew Thompson's answer, note that an object that implements the Icon interface knows how to paint something, but it may

Translucent JLabel not properly showing background

由 一个人想着一个人 提交于 2019-12-17 14:23:23
问题 I have the following line: label.setBackground(new java.awt.Color(0, 150, 0, 50)); I place this in a mouseReleased method within a MouseAdapter.

My problem is this: -When I click on the label, it shows the translucent green color, but it is showing the background of ANOTHER JLabel, not the one I click on. No matter which

Java: how to add image to Jlabel?

由 点点圈 提交于 2019-12-17 09:43:11
问题 Image image = GenerateImage.toImage(true); //this generates an image file JLabel thumb = new JLabel(); thumb.setIcon(image) 回答1: You have to supply to the JLabel an Icon implementation (i.e ImageIcon ). You can do it trough the setIcon method, as in your question, or through the JLabel constructor: Image image=GenerateImage.toImage(true); //this generates an image file ImageIcon icon = new ImageIcon(image); JLabel thumb = new JLabel(); thumb.setIcon(icon); I recommend you to read the Javadoc
