How can I set up PyCharm to launch from the Launcher?（ubuntu pycharm 无法 lock from launcher 问题解决）

PyCharm can create it's own launcher icon (but it's not created by default).

All you have to do is:

1. Start PyCharm.
2. From the Tools menu, select "Create Desktop Entry..."
3. Tick the corresponding box if you want the launcher for all users.
4. If you selected "Create entry for all users", you will be asked for your password.
5. A green message bubble should appear informing you that it was successful.
6. You should then be able to find PyCharm in the Unity Dash or pin it to the launcher.

Note: You may need a system restart before it appears.
