如何从紧凑框架中的链接标签中删除下划线？由于标签和文本框没有点击事件，我必须使用linklabel作为其支持点击事件。
尝试this解决方案，但无法正常显示错误错误：运营商'！'不能应用于'System.Drawing.FontStyle'类型的操作数
有任何线索如何删除下划线并更改字体颜色？

一种简单的方法是从import java.io.IOException;
import java.util.ArrayList;
import javax.bluetooth.DeviceClass;
import javax.bluetooth.DiscoveryAgent;
import javax.bluetooth.DiscoveryListener;
import javax.bluetooth.LocalDevice;
import javax.bluetooth.RemoteDevice;
import javax.bluetooth.ServiceRecord;
/**
* Class that discovers all bluetooth devices in the neighbourhood and
displays
* their name and bluetooth address.
*/
public class BluetoothDeviceDiscovery implements DiscoveryListener {
// object used for waiting
private static Object lock = new Object();
// vector containing the devices discovered
public static ArrayList<RemoteDevice> devices;
public BluetoothDeviceDiscovery()
{
devices = new ArrayList<RemoteDevice>();
}
// main method of the application
public static void main(String[] args) throws IOException {
//create an instance of this class
BluetoothDeviceDiscovery bluetoothDeviceDiscovery=new
BluetoothDeviceDiscovery();
//display local device address and name
LocalDevice localDevice = LocalDevice.getLocalDevice();
System.out.println("Address: "+localDevice.getBluetoothAddress());
System.out.println("Name: "+localDevice.getFriendlyName());
//find devices
DiscoveryAgent agent = localDevice.getDiscoveryAgent();
System.out.println("Starting device inquiry…");
agent.startInquiry(DiscoveryAgent.GIAC, bluetoothDeviceDiscovery);
try {
synchronized(lock){
lock.wait();
}
}
catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("Device Inquiry Completed. ");
//print all devices in devices
int deviceCount=devices.size();
System.out.println(deviceCount);
if(deviceCount <= 0){
System.out.println("No Devices Found ."); }
else{
//print bluetooth device addresses and names in the format [ No. address (name) ]
System.out.println("Bluetooth Devices:" );
for (int i = 0; i < deviceCount; i++)
{
RemoteDevice remoteDevice=(RemoteDevice)devices.get(i);
System.out.println((i+1)+". "+remoteDevice.getBluetoothAddress()+"
("+remoteDevice.getFriendlyName(true)+")");
}
}
}
public void deviceDiscovered(RemoteDevice btDevice, DeviceClass cod)
{
System.out.println("Device discovered:
"+btDevice.getBluetoothAddress());
//add the device to the vector
if(!devices.contains(btDevice))
{ devices.add(btDevice);
}
}
public void servicesDiscovered(int transID, ServiceRecord[] servRecord) {
}
public void serviceSearchCompleted(int transID, int respCode) {
}
public void inquiryCompleted(int discType)
{
synchronized(lock){ lock.notify();
}
switch (discType)
{
case DiscoveryListener.INQUIRY_COMPLETED :
System.out.println("INQUIRY_COMPLETED");
break;
case DiscoveryListener.INQUIRY_TERMINATED :
System.out.println("INQUIRY_TERMINATED");
break; case DiscoveryListener.INQUIRY_ERROR :
System.out.println("INQUIRY_ERROR");
break;
default : System.out.println("Unknown Response Code");
break;
}
}
}
继承用户控件并覆盖LinkLabel。其中使用GDI +呈现LinkLabel的内容。您仍然可以使用LinkLabel的所有其他功能，但文本不会像您希望的那样有下划线。
以下几行：
