comfyui-touch-numeric

Touch-friendly keypad, steppers, and slider modal for seed and INT/FLOAT widgets — seed history, keypad lock, and control_after_generate folded in.

Part of a family of mobile-first ComfyUI usability packs — touch-friendly HTML modals that replace clunky native LiteGraph controls, detected by widget name, additive and non-clobbering. They share the @laurigates/comfy-modal-kit modal primitives and its cross-pack field-provider registry, so this keypad also renders inline inside the prompt-editor. Siblings: gallery-loader, model-gallery, prompt-editor, sampler-info, touch-connect, touch-resize, touch-tooltips.

The touch keypad modal for seed / noise_seed widgets: paste or tap an 18-digit value, one-tap Randomize, keypad lock, control_after_generate as a segmented control, and per-session seed history.

Install

cd <ComfyUI>/custom_nodes
git clone https://github.com/laurigates/comfyui-touch-numeric

Restart ComfyUI; hard-refresh the browser tab (Ctrl+Shift+R / Cmd+Shift+R).

What it does

Detects seed / noise_seed widgets (and other INT/FLOAT numeric widgets) by name and folds their controls into one touch-friendly modal opened via widget.onPointerDown — additive, with graceful fallback to the native widget when there's no match. The modal gives you:

• A big keypad + paste field — tap the digits or paste an 18-digit value; input is parsed and clamped to the widget's bounds ([0, 0xffffffffffffffff] for seeds), kept as an exact BigInt so no precision is lost.
• One-tap Randomize — a cryptographically-random (crypto.getRandomValues) 64-bit-safe integer, generated and clamped within the widget's bounds.
• Keypad lock — freeze the value so the keypad, the text field, Randomize and history-restore are ignored until unlocked. It guards editing, not generation: to keep a seed stable across runs set control_after_generate to Fixed. The latch is per-dialog and resets when the modal closes.
• control_after_generate as a segmented control — the adjacent core combo rendered as a 4-state toggle (Fixed / Increment / Decrement / Randomize).
• Per-session seed history — recent values (newest first), tap-to-restore; in-memory only, cleared on reload.

Because it registers a seed field provider with @laurigates/comfy-modal-kit, the same keypad also renders inline inside the prompt-editor modal — no separate integration needed.

Two of the affordances above are modal-only and are omitted from the inline mount, because the host editor's contract makes them incoherent rather than merely redundant. The host renders its own row for every widget on the node, including control_after_generate, so a segmented control here would be a second UI for one widget — and a live-writing one, racing the host's Save/Cancel. The keypad lock is per-dialog state the host cannot read, so it could never gate the host's Save. Both remain in this pack's own canvas modal, which owns its commit and is the only editor on screen.

The seed history is also capped to 5 rows inline, with a "+N more" line pointing at the full list. The host modal owns the only scroll region, so the inline mount must not be a scroll container — otherwise it swallows the field-list scroll gesture without being able to chain it back out.

Compatibility

• ComfyUI: modern Vue frontend (comfyui-frontend-package >= 1.40) for the widget.onPointerDown interception hook.
• Frontend changes (JS/CSS) take effect on browser hard-refresh — no restart.
