Copy qrtunnel into remote desctop. 12 | 2. Run it inside remote desctop, click "Sender". 13 | 3. Make sure the whole UI of qrtunnel's SenderForm is not coverd by any window or remote desctop border. You can change the size and layout of QR code images in "Configs"(enter from ReceiverForm). 14 | 4. Run qrtunnel outside remote desktop, click "Start", you will see a message that describes the capture region. If not, probably because the SenderForm is not fully displayed. 15 | 5. Switch to SenderForm inside remote desktop, choose a file/folder to be sent. Then click "Send". You will see progresses on both side. 16 | 6. Wait for thansfer complete. 17 | 18 | # 为什么使用qrtunnel 19 | 当你使用的远程桌面的时候，你发现你不能从远程桌面内部拷贝文件到外部，让这个小工具来帮助你。 20 | 21 | # 如何使用 22 | 1. 把qrtunnel复制到远程桌面里面。 23 | 2. 在远程桌面内运行qrtunnel，点击"Sender"。 24 | 3. 保证SenderForm的界面完整显示，不被其他窗口或者远程桌面的边框所遮盖。你可以在设置界面调整QR code图片的大小和布局（从ReceiverForm进）。 25 | 4. 在远程桌面外运行qrtunnel，点击"Start"，你会看到一个消息描述了捕捉区域，如果没有，很可能是因为SenderForm被挡住了没有完全显示。 26 | 5. 在远程桌面里的SenderForm界面选择需要发送的文件/文件夹，然后点击"Send"，你会在两边都看到传输进度条。 27 | 6. 等待传输完成。 28 | -------------------------------------------------------------------------------- /core/pom.xml: -------------------------------------------------------------------------------- 1 | 2 | 5 | 6 | qr-tunnel 7 | com.willswill.qrtunnel 8 | 1.0 9 | 10 | 4.0.0 11 | 12 | core 13 | 14 | 15 | -------------------------------------------------------------------------------- /core/src/main/java/com/willswill/qrtunnel/core/AppConfigs.java: -------------------------------------------------------------------------------- 1 | package com.willswill.qrtunnel.core;
