CmdWindowMeasurement

Applies and queries window measurements in a single command.

Groups:

• position (set/get)
• inner size (set/get)
• outer size (get)
• surface size (get)

Platform Notes

• WASM: uses the same response shape as native. While the window is not ready yet, it returns an empty payload with success=true (eventual consistency).
• In HiDPI, surface size reflects real drawing-buffer pixels (not only CSS pixels).

Arguments

Field	Type	Description
windowId	u32	Window ID
position	Option	New outer position (optional)
size	Option	New inner size (optional)
getPosition	bool	Includes position in response
getSize	bool	Includes size in response
getOuterSize	bool	Includes outerSize in response
getSurfaceSize	bool	Includes surfaceSize in response

Response

Returns CmdResultWindowMeasurement:

Field	Type	Description
success	bool	Whether command was applied successfully
message	String	Status (includes transient/deferred state)
position	Option	Current/updated position when requested
size	Option	Current/updated inner size when requested
outerSize	Option	Current outer size when requested
surfaceSize	Option	Current surface size when requested

Notes

• Patch fields are optional: send only what you want to change.
• position and size, when sent, are also returned in the response payload.
• If windowId/GPU are not ready yet, the command returns success=true with empty read fields (eventual consistency).
