java - 使用 FileDialog 选择多个文件不起作用

Question

当窗口对话框打开时，我无法选择多个文件。

void setup() {
  size(100,100);
  select_multi_files_via_FileDialog();
}

import java.awt.FileDialog;
import java.awt.Frame;
File [] select_multi_files;
void select_multi_files_via_FileDialog() {
  Frame frame = null;
  FileDialog dialog = new FileDialog(frame, "select file", FileDialog.LOAD);
  dialog.setVisible(true);
  dialog.setMultipleMode(true);
  String directory = dialog.getDirectory();
  println("multifile is",dialog.isMultipleMode());
  select_multi_files = dialog.getFiles();

  if(select_multi_files != null && select_multi_files.length > 0) {
    printArray(select_multi_files);
  }
}

我希望能够在对话框窗口中选择一个或多个文件，但无法使用 SHIFT 或 CTRL 进行多项选择

控制台输出:

2019-03-31 07:29:28.173 java[1808:250416] warning: <NSRemoteView: 0x7fc2801911b0> determined it was necessary to configure <NSOpenPanel: 0x7fc2798f75e0> to support remote view vibrancy
multifile is true

我不知道这是否是来自 OSX-Mojave、Java、NSRemoteView、NSOpenPanel 的错误，还是我的代码中遗漏了某些内容？

Answer 1

要启用多选，您只需更改文件对话框的调用顺序

来自:

FileDialog dialog = new FileDialog(frame, "select file", FileDialog.LOAD);
dialog.setVisible(true);
dialog.setMultipleMode(true);

致:

FileDialog dialog = new FileDialog(frame, "select file", FileDialog.LOAD);
dialog.setMultipleMode(true);
dialog.setVisible(true);
