After opening a JFileChooser from a button in a window, the File Chooser opens, then the original window closes. I would like to keep that original window open throughout when the user is using the File Chooser and after.
My code:
// Code from the class that makes the original window that has the launch button
FilePicker filePicker = new FilePicker();
public void actionPerformed(ActionEvent e) {
txtImportLog.append("\nUser selecting file");
if (filePicker.canPick()) {
filePicker.init();
filePicker.getImportFile();
} else {
txtImportLog.append("\nCan't pick more files.");
}
}
});
// Code from the class that creates a FilePicker
//(yes, I know the getImportFile() and init() methods are setup badly, its just for
// testing right now
// Initialize - only should be called once
public void init() {
filePicker = new JFileChooser();
interval1 = 0;
interval2 = 0;
testFile = new File(""); // for testing. clearly.
}
// Get a file to import
public static File getImportFile() {
filePicker.setFileSelectionMode(JFileChooser.FILES_ONLY);
filePicker.showOpenDialog(filePicker);
return filePicker.getSelectedFile();
}
Oops, I simply had code (auto-generated by Eclipse plug-in WindowBuilder) that looked for when the parent window lost focus, it would close the application. The file chooser's parent was the main window. So when the user clicked the "Open file chooser" button, focus of the main window would be lost, closing the application.
