imageicon

问题 I have many planes(threads) that move in window, and I want switch the ImageIcon according to the direction of the plane. For example: if a plane goes to the right, the imageIcon of the plane is right and then plane goes to the left, exchange the imageIcon for the plane is left. How can I do that in method paintComponent? Sorry for my bad english. 回答1: If you're talking about swapping the ImageIcon displayed by a JLabel, then you should not switch ImageIcons in paintComponent but rather

问题 Does anyone know how to set a C# console application's icon in the code (not using project properties in Visual Studio)? 回答1: You can't specify an executable's icon in code - it's part of the binary file itself. From the command line you'd use /win32icon:<file> if that's any help, but you can't specify it within the code of the application. Don't forget that most of the time the application's icon is displayed, your app isn't running at all! That's assuming you mean the icon for the file

问题 In my application I am extracting data from a project DB. When I do that I want to signal to user that data extraction is in progress.

问题 So I looked through this thread and saw the suggestion of using HTML for resizing. I've been going through the Oracle website but it only provided example for text customization in JLabels using HTML. Can I get an example of a JLabel with HTML parameters? 回答1: This basically requires you to have a URL reference to the image in question. This is quite easy to achieve if the image is an embedded resource (as demonstrated below), but you should be able to generate a URL from file using File

问题 I am using the NetBeans GUIBuilder to make a JPanel Form. I added a JLabel and used NetBeans' interface to give it an icon from an external image (.png). The path is verified and the image shows up on the GUIBuilder screen. It even shows up when I click the "Preview Design" button. It DOES NOT show up when I RUN the project. The rest of the GUI appears as it should. Do any of you know why this happening and/or how to fix it? A lot of you have been asking for an SSCCE. Since the code is

问题 Is there any way to easily delete an ImageIcon completely from the screen? I can't find one anywhere. ImageIcon image = new ImageIcon("candle.gif"); image.paintIcon(this, g, 150, 80) For example, if I wanted to get rid of "image" later on when a button is pressed, what would be the appropriate code? (Not for the button, I know how to do that). 回答1: Don't reinvent the wheel. The easiest way to paint an Icon is to use a JLabel. The code would be something like: ImageIcon icon = new ImageIcon(..
