Auto Layout Padding Controls

Select a single auto-layout frame or group to reveal padding regions and side handles on the canvas.

Interaction

Drag any side handle to change that padding side.
Click a padding region to open a numeric input for that side; blur closes the input and removes the active outline.
The active handle stays centered inside the current padding region while the padding value changes.
Left and right padding regions stay clickable across the full container height.
Hold Alt / Option before or during the drag to mirror the opposite side.
Nested auto-layout containers resolve their controls in stage space, so handles stay aligned even inside parent frames or groups.

The padding value label updates during dragmove without a pointer arrow.
The selection size label updates during dragmove when the container size changes because of hug sizing.
Handle hit areas stay interactive while the visible handle keeps a fixed visual size across zoom levels.

One completed drag creates one history entry.
The canvas drag path and setAutoLayoutPadding() reuse the same padding validation and clamping logic.
Negative padding values are clamped to 0.
On fixed axes, opposite padding sides are also clamped so their total never exceeds the container size, and the live value label reflects the applied clamped value.
