QingBoard is an on-screen keyboard for Linux that aims to mimic the behaviour of a physical keyboard as closely as possible.
This GTK 3 application injects real key events through uinput and is designed for touch devices, temporary keyboard replacement, and accessibility-oriented desktop workflows.
It offers hardware-like modifier key behaviour, shortcut support, multi-touch input, long-press key repeat, and a Space cursor mode for sending directional key presses with sliding gestures. The interface is customizable with themes, opacity, and font size controls.
This is free and open source software.
