Question

我正在创建一个文本编辑器作为一个侧面项目，到目前为止，我正在努力保存和加载文本的字体字母，颜色和装饰;换句话说，我只能保存纯文本。我的问题是，如何保存和加载所有这些？

private void Edit() {//This is the method where the program edits the text
    StyledDocument doc = this.tpText.getStyledDocument();
    Style estilo = this.tpText.addStyle("miEstilo", null);
    StyleConstants.setForeground(estilo, colour); //Color
    StyleConstants.setFontFamily(estilo, fontLetter);//Letter
    StyleConstants.setFontSize(estilo, size);//Size
    StyleConstants.setBold(estilo, bold);//Bold
    StyleConstants.setItalic(estilo, italics);//Italics
    StyleConstants.setUnderline(estilo, underline);//Underline
    doc.setCharacterAttributes(this.tpText.getSelectionStart(), this.tpText.getSelectionEnd() - this.tpText.getSelectionStart(), this.tpText.getStyle("miEstilo"), true);//The only text that will be edited is the one that the user highlights
}

private void comboxFontsActionPerformed(java.awt.event.ActionEvent evt) {//This is one of the methods in which the program edits the text                                            
        this.fontLetter = (String) this.comboxFonts.getSelectedItem();
        Edit();
}
private void mibtnSaveAsActionPerformed(java.awt.event.ActionEvent evt) {//Save as... menu item button                                            
        int saveResult = fileSelect.showSaveDialog(null);
            if (saveResult == fileSelect.APPROVE_OPTION) {
                saveFile(fileSelect.getSelectedFile(), this.tpText.getText());
                this.mibtnSave.setEnabled(true);
            }
    }
public void saveFile(File file, String contents) {//Save File
    BufferedWriter writer = null;
    String filePath = file.getPath();

    try {
        writer = new BufferedWriter(new FileWriter(filePath));
        writer.write(contents);
        writer.close();
        this.tpText.setText(contents);
        currentFile = file;
    } catch (Exception e) {

    }
}

public void openFile(File file) {//Load File
    if (file.canRead()) {

        String filePath = file.getPath();
        String fileContents = "";

        if (filePath.endsWith(".txt")) {
            try {
                Scanner sc = new Scanner(new FileInputStream(file));
                while (sc.hasNextLine()) {
                    fileContents += sc.nextLine();
                }

                sc.close();
            } catch (FileNotFoundException e) {

            }
            this.tpText.setText(fileContents);
            currentFile = file;
        } else {
            JOptionPane.showMessageDialog(null, "Only .txt files are supported.");

        }
    } else {
        JOptionPane.showMessageDialog(null, "Could not open file...");
    }
}

我不知道我的问题是否正确，但如果您尝试保存除纯文本之外的样式，您可以执行以下操作。
将所有样式属性保存在文本文件旁边的另一个文件中，您可以在打开文本文件时将其恢复。

从文本窗格java保存字体
