Excel 如何使用savedilogue javafx保存文件
我已经创建了excel文件,我希望该文件在JavaFx文件选择器中显示为“文件名”框。因此,我可以使用SaveDialogueBox将该文件保存到任何需要的地方 代码:Excel 如何使用savedilogue javafx保存文件,excel,javafx,save,Excel,Javafx,Save,我已经创建了excel文件,我希望该文件在JavaFx文件选择器中显示为“文件名”框。因此,我可以使用SaveDialogueBox将该文件保存到任何需要的地方 代码: WriteExcelFile test = new WriteExcelFile(); File exlFile = new File("c:/temp/"+tabName+".xls"); WorkbookSettings wbSettings = new WorkbookSettings(); wbSetting
WriteExcelFile test = new WriteExcelFile();
File exlFile = new File("c:/temp/"+tabName+".xls");
WorkbookSettings wbSettings = new WorkbookSettings();
wbSettings.setLocale(new Locale("en", "EN"));
WritableWorkbook workbook = Workbook.createWorkbook(exlFile, wbSettings);
workbook.createSheet("Report", 0);
WritableSheet excelSheet = workbook.getSheet(0);
//createLabel(excelSheet);
Label label;
// Write a few headers
label = new Label(0, 0,"ID");
excelSheet.addCell(label);
label = new Label(1, 0,"BIC");
excelSheet.addCell(label);
label = new Label(0, 1,"Hi 0");
excelSheet.addCell(label);
label = new Label(1, 1,"Hi 1");
excelSheet.addCell(label);
workbook.write();
workbook.close();
Stage stage = (Stage) delBtn.getScene().getWindow();
FileChooser fileChooser = new FileChooser();
fileChooser.setTitle("Open Resource File");
fileChooser.getExtensionFilters().addAll(
new ExtensionFilter("Microsoft Workbook", "*.xls"));
File selectedFile = fileChooser.showSaveDialog(stage);
if (selectedFile != null) {
//What to write here
}
是的,我用另一种方式得到了答案
