Feature Request: “Virtual Mouse Button” Mode

[StriverKlu]

Hi gujjwal00,

First of all, thank you for building AVNC. It’s one of the best VNC clients on Android. I use it daily to run Ubuntu inside Termux on my Android phone.

I’d like to propose a new input mode inspired by MultiVNC and small UMPC devices like the GPD MicroPC.

Problem:

Currently, mouse clicks in AVNC rely mainly on gestures such as:

• tap = left click
• long press = right click
• double tap and swipe = drag remote content

While this works, it can feel imprecise during desktop-oriented workflows, especially when:

• manipulating UI elements (e.g. resizing windows)
• dragging windows/files
• selecting text

Proposed Solution:

Add an optional “Virtual Mouse Button” mode.

In this mode:

A small area on the left edge (or optionally bottom-left corner) of the screen displays:

• Left mouse button
• Middle mouse button
• Right mouse button

The remaining screen area acts purely as a touchpad for cursor movement:

• moving finger = move cursor
• no tap-to-click gestures
• no long-press/right-click simulation

This creates a control scheme similar to GPD MicroPC, which allows true two-thumb operation:

• Left thumb → mouse buttons
• Right thumb → cursor movement

This should be more precise and ergonomic than gesture-based clicking.

Benefits include:

• more accurate cursor control
• easier drag-and-drop
• reduced accidental clicks

Here are the examples of the virtual mouse button layout:

Here is a picture of the GPD MicroPC, which inspires this mode:

I think this would make AVNC more usable for Linux desktop environments running through Termux.

Thanks again for the great project!

Best,
Kai
