仅在SWT中而不在jface中复制文件时显示进度条
[英]Display Progress bar while copying files in only SWT not in jface
问题描述
I am trying to create one installation wizard in SWT. 
我正在尝试在SWT中创建一个安装向导。
I have some code that displays a progress bar while copying files. 我有一些代码在复制文件时显示进度条。

My code is displaying the progress bar, but the files are not being copied. 我的代码显示进度条，但未复制文件。
How can I fix this? 我怎样才能解决这个问题？
EDIT: 编辑：
I am trying with sample code. 我正在尝试示例代码。
public static void main (String [] args) throws IOException
{
Display display = new Display ();
Shell shell = new Shell (display);
shell.open ();
File srcFile=new File("C:\\Users\\aa00333221\\Desktop\\s");
File destFile=new File("C:\\Users\\aa00333221\\Desktop\\S2");
String[] files=srcFile.list();
System.out.println("files :"+files);
f1=numberOfFiles(srcFile);
System.out.println("Count: "+f1);
ProgressBar bar = new ProgressBar (shell, SWT.SMOOTH);
bar.setLocation(100,90);
bar.setSize(280,14);
bar.setMaximum(f1);
for (String name : files) {
System.out.println("File name: " + name);
}
for(int i=0;i<f1;i++){
System.out.println("Files[i]: "+files[i]);
strSubDestDir = srcFile.getAbsolutePath().concat(File.separator).concat(files[i]);
subDestDir = new File(strSubDestDir);
File newFile = new File(destFile.getAbsolutePath().concat(File.separator).concat(files[i]));
FileUtils.copyFile(subDestDir, newFile);
bar.setSelection (i+1);
int x=i+1;
System.out.println("bar.setSelection (i+1): "+x );
System.out.println("copy done for "+strSubDestDir +"to "+newFile);
}
while (!shell.isDisposed ())
{
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}
public static int numberOfFiles(File srcDir) {
int count = 0;
System.out.println("calling NumbeerOfFiles Method");
File[] listFiles = srcDir.listFiles();
for(int i = 0; i < listFiles.length; i++){
if (listFiles[i].isDirectory()) {
count += numberOfFiles(listFiles[i]);
} else if (listFiles[i].isFile()) {
count++;
}
}
return count;
}
This is working for files only, not for subfolders.
Have to display the progress bar while copying folders and subfolders also.

Not quite sure where exactly you're having difficulties, but here is some code that processes a directory file by file and updates a ProgressBar . 不太确定您到底在哪里遇到困难，但是这里有一些代码可以逐个文件处理目录并更新ProgressBar 。 You should be able to modify it according to your needs: 您应该能够根据需要对其进行修改：
public static void main(String[] args)
{
final Display display = new Display();
final Shell shell = new Shell(display);
shell.setText("StackOverflow");
shell.setLayout(new FillLayout(SWT.VERTICAL));
Button button = new Button(shell, SWT.PUSH);
button.setText("Start copying");
final ProgressBar bar = new ProgressBar(shell, SWT.NONE);
button.addListener(SWT.Selection, new Listener()
{
@Override
public void handleEvent(Event event)
{
String path = new DirectoryDialog(shell, SWT.OPEN).open();
if (path != null && !"".equals(path))
{
File file = new File(path);
final File[] files = file.listFiles();
if(files == null)
return;
bar.setMinimum(0);
bar.setMaximum(files.length);
bar.setSelection(0);
Runnable run = new Runnable()
{
@Override
public void run()
{
for(File f : files)
{
System.out.println(f);
display.asyncExec(new Runnable()
{
@Override
public void run()
{
bar.setSelection(bar.getSelection() + 1);
}
});
try
{
Thread.sleep(100);
}
catch (InterruptedException e)
{
e.printStackTrace();
}
}
display.asyncExec(new Runnable()
{
@Override
public void run()
{
bar.setSelection(0);
}
});
System.out.println("DONE");
}
};
new Thread(run).start();
}
}
});
shell.pack();
shell.open();
while (!shell.isDisposed())
{
if (!display.readAndDispatch())
{
display.sleep();
}
}
display.dispose();
}
