Set locale properly to a JFileChooser

由 耗尽温柔 提交于 2019-12-05 01:58:02
问题 I'm having a little problem when I change Locale at runtime. The Goal I have to change the Locale of my application language according to a configuration file. This locale does not necessarily be the same of the host/OS locale nor the JVM default locale. Moreover, I can't modify user.language when I call the application. Then, I must do that at runtime. The Problem Summarizing my code, I read the configuration file and get the different options (including locale). After that, I initialize the

由 為{幸葍}努か 提交于 2019-12-04 18:30:19
I am using a JFileChooser and the showSaveDialoge() and setSelectionMode(JfileChooser.DIRECTORIES_ONLY) to set where a preselected file will be saved and what it will be called.

How to generate a stand-alone JFileChooser dialog box on top of other windows?

由 不打扰是莪最后的温柔 提交于 2019-12-04 18:09:35
Like some other people who have asked similar questions, I was going nuts trying to 'fix' my JFileChooser dialog box generation code until I noticed that it is being generated, but it is appearing underneath all other windows and does not have an associated taskbar icon (so there was no clue at all that it existed!). I am aware of these similar questions: Bringing JFileChooser on top of all windows JFileChooser from a command line program and popping up Underneath all windows ...but the answers to those questions seem overly complex, involving creating more GUI elements, which I can't believe

由 妖精的绣舞 提交于 2019-12-04 17:20:34
问题 I want to change the default directory of my JFileChooser to "My Music" on Windows. This directory is C:\Users\Fre\Music on my account because my username is Fre The default is set on C:\Users\Fre\Documents (depends on OS i think). How can I change this? 回答1: You can use the API method setCurrentDirectory when initializing your JFileChooser objects: public void setCurrentDirectory(File dir) Sample usage might be like: yourFileChooser.setCurrentDirectory(new File (System.getProperty("user.home

System look and feel layout on JFileChooser but with nimbus look and feel theme

由 南楼画角 提交于 2019-12-04 10:54:22
问题 The windows look and feel layout on JFileChooser is much better than other look and feels like nimbus. So I'm looking for a way to have the layout of a system look and feel but have nimbus or others theme on top. Is this possible? If so how can it be done? 回答1: It's possible, though I don't know whether it's recommended. I managed to get it to work by asking the view to update itself on all but the topmost JFileChooser component (since that would replace all the chooser components with the

Scrollbar in JFileChooser gives error

When I use JFileChooser, the first time I use its scrollbar, I get two or four copies of the following error message: 2016-01-08 18:37:17.706 java[14158:2289154] inOptions: { JavaCUIThumbStartKey = 0; "is.flipped" = 0; kCUIOrientationKey = kCUIOrientVertical; kCUIThumbProportionKey = "0.497863233089447"; max = 0; pressedpart = 0; state = normal; value = 0; widget = scrollbar; Here is sample code that has this behavior: package tests; import java.awt.event.*; import javax.swing.*; public class SwingTest extends JFrame { public SwingTest() { JButton button = new JButton("Choose files"); add

JFileChooser use within JApplet

由 筅森魡賤 提交于 2019-12-04 07:25:40
Can a JApplet use a JFileChooser so that the user can select a file on his hard-drive? Or would this violate Java applet security? (I'm assuming that the default security settings are being used. I don't want to ask my users to grant me extra permissions.) This thread indicates that you need to digitally sign your applet before a JFileChooser is permitted. As mentioned, you need to sign your applet, which result in a "vague security warning" when the user is presented the applet. When the user accept to run this applet, the applet is given full access and functions like an ordinary application

Making a JFileChooser select the text of the file name but not the extension

由 馋奶兔 提交于 2019-12-04 05:15:16
I'd like the text in the file name field of the JFileChooser save dialog to select just the file name and not the extension. I currently have this: And want it to look like this: This is a simple change, but one that makes saving a file much easier, in my opinion, since the user can start typing the file name right away without erasing the extension accidentally. I know I can forcefully add the extension if it's missing, but I'd rather not do this because the extension isn't mandatory and I don't feel it should be enforced. So, is there any way I could achieve this? The API does not offer that
