JFileChooser change default directory in Windows

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.getProperty("file.separator")+ "Music"));

回答2:

why don't you just give the FileChooser the path when you create it, like:

JFileChooser chooser = new JFileChooser("C:\\Users\\Fre\\Music\\");

Sorry for taking your time, Just found the answer myself:

String userhome = System.getProperty("user.home");
JFileChooser fc = new JFileChooser(userhome +"\\Music");

回答4:

JFileChooser openFile = new JFileChooser("C:\\Users\\Fre\\Music");

Creating all your own code, so as to set a default file directory is unnecessary and lengthy. A much easier and quicker way of doing it is by just right clicking on the File Chooser itself on Design view and right clicking 'customise code'.

Customise Code for File Chooser

This will show you the vital code for that GUI component. From the drop down box next to the top line of code, select 'custom creation'.

This will allow you to customise what fileChooser = is assigned to. Between the curly brackets JFileChooser() you can either hard code in the file directory with speech marks like this.

JFileChooser("C:\Users\user\Documents")

or type in a name that for a variable you created earlier. This variable would hold the file directory. I would recommend the latter option, though either will work fine.

Hope this helps.

p.s. sorry about having to use a link for the photo. I don't have enough privilege yet.

You can Change the default directory of my JFileChooser to "Directory you want" on Windows

JFileChooser fileChooser = new JFileChooser();
fileChooser.setCurrentDirectory(new File("put here your directory"));
int result = fileChooser.showOpenDialog(getParent());
if (result == JFileChooser.APPROVE_OPTION) 
{
    File selectedFile = fileChooser.getSelectedFile();
    jTextField.setText(selectedFile.getAbsolutePath());
}
