Distinguishing between local and remote mouse click events in VNC server

If you are using a VNC (Virtual Network Computing) server to remotely control another computer, you may have encountered the issue of distinguishing between local and remote mouse click events. This can be a common challenge for users who are new to VNC and remote desktop access. In this article, we will explain what local and remote mouse click events are, why they matter, and how you can differentiate between them in a VNC server.

Understanding local and remote mouse click events

When you are using a VNC server to control another computer remotely, there are essentially two types of mouse click events that can occur:

• Local mouse click events: These are the mouse click events that occur on the computer where the VNC server is running. For example, if you are using a VNC client on your laptop to control your desktop computer, any mouse click you make on your laptop will be considered a local mouse click event.
• Remote mouse click events: These are the mouse click events that occur on the computer you are remotely accessing. Continuing with the previous example, if you click on an icon or a file on your desktop computer using the VNC client on your laptop, it will be considered a remote mouse click event.

It is important to distinguish between these two types of mouse click events because the actions triggered by them can be different. For instance, a local mouse click event may perform an action on the computer where the VNC server is running, while a remote mouse click event may perform an action on the remote computer being accessed.

Differentiating between local and remote mouse click events

Fortunately, most VNC servers provide a way to differentiate between local and remote mouse click events. The exact method may vary depending on the VNC server software you are using, but we will outline a common approach using the popular VNC server software, TightVNC.

In TightVNC, you can differentiate between local and remote mouse click events by enabling the PointerEvents option. This option allows you to display a visual cue on the screen whenever a mouse click event occurs.

To enable the PointerEvents option in TightVNC, follow these steps:

1. Launch the TightVNC server software on the computer you want to remotely access.
2. In the TightVNC server window, click on the "Options" button.
3. In the "Options" dialog box, go to the "Inputs" tab.
4. Check the box next to "PointerEvents" to enable it.
5. Click "OK" to save the changes.

Once you have enabled the PointerEvents option, you will notice a visual cue on the screen whenever you click the mouse. This cue can help you determine whether a mouse click event is local or remote.

Conclusion

Distinguishing between local and remote mouse click events in a VNC server is essential for understanding the actions triggered by each type of event. By enabling the PointerEvents option in a VNC server like TightVNC, you can easily differentiate between local and remote mouse click events. This can be particularly useful for troubleshooting and ensuring that your actions are performed on the intended computer.
