我需要将多个jradiobox按钮组和一个jcombobox连接到一个jbutton

Question

我需要做的是将两个jradiobuttongroup和一个组合框连接到一个jbutton，当我单击jbutton时，所有选项的总数将显示在一个文本字段中。

****(编辑(总的来说，我的意思是你把选择的选项加起来(每个类别一个(。您将它们连接到calcular importe jbutton，并在ver dialogo jbutton中创建一个对话框窗口，显示您选择的微评估器和最终价格***

(重要通知(我正在使用eclipse，不能使用<字符串和combobox，所以如果有人能帮我找到解决方案，我将不胜感激

您想要做的正是您对JTextField所做的。。。将所有相关的Swing组件声明为类成员变量，以便可以在Ventapc类范围内的任何地方访问它们。完成后，您可以创建一个方法来验证所有必填字段是否都有选择，维护这些选择的总和，并将总价插入可用的JTextField(textField(中。类似这样的东西：

private boolean verifyEntriesAndSetTotal() {
boolean res = true;
precioTotal = 0;

// Processor
if (micro.getSelectedIndex() != -1) {
switch (micro.getSelectedItem().toString().toLowerCase()) {
case "intel":
precioTotal += intel;
break;
case "athlon":
precioTotal += athlon;
break;
case "turion":
precioTotal += turion;
break;
default:
return false;
}
}
else {
return false;
}

// Motherboard
if (asusbutton.isSelected()) {
precioTotal += asus;
}
else if (gigabutton.isSelected()) {
precioTotal += giga;
}
else if (msibutton.isSelected()) {
precioTotal += msi;
}
else {
return false;
}

// Memory
if (twoGB.isSelected()) {
precioTotal += twogb;
}
else if (fourGB.isSelected()) {
precioTotal += fourgb;
}
else if (eightGB.isSelected()) {
precioTotal += eightgb;
}
else if (sixteenGB.isSelected()) {
precioTotal += sixteengb;
}
else {
return false;
}

//The OPTIONALS
// Monitor Option
if (chkMonitor.isSelected()) {
precioTotal += monitor;
}

// Fixed Disk Option
if (chkFixedDisk.isSelected()) {
precioTotal += discofijo;
}

// Set the total price
textField.setText(String.valueOf(precioTotal));
return res;
}

在calcuimp按钮的ActionPerformed事件中，您会得到如下内容：

if (!verifyEntriesAndSetTotal()) {
// Not all required items are selected.
JOptionPane.showMessageDialog(frmVentaPc, "Not all required selections have been made!", 
"Invalid Selections", JOptionPane.WARNING_MESSAGE);
}
