我有一项任务是创建一个创建顺序文件的swing GUI,以及另一个读取顺序文件的swing GUI。我不知道如何从组合框中获取价值。让我们说组合框的名称是comboBox_1,命令是什么?
if ( studentID > 0 ) {
//***********************
output.writeUTF(textField.getText());
output.writeUTF(textField_1.getText());
output.writeUTF(textField_2.getText());
output.writeInt(studentID);
output.writeUTF(textField_4.getText());
output.writeUTF(textField_5.getText());
output.writeUTF(textField_6.getText());
output.writeUTF(textField_7.getText());
output.writeUTF(textField_8.getText());
//PLACE FOR COMBOBOXES
output.writeInt(maths);
output.writeInt(buisness);
output.writeInt(programming);
output.writeInt(accounting);
output.writeInt(art);
output.writeInt(music);
}
答案 0 :(得分:0)
如果你的组合框包含字符串列表,你可以
(String)comboBox_1.getSelectedItem();
