Every panel in the develop column declared its inputs and its callbacks and had `app.slint` bind each one to a property or a callback on the window root. That is fine while a panel is drawn once. N9 draws them a second time, in the portrait dock, and the wiring is what would have to be copied: `MaskPanel` alone ran to forty lines of forwarding, and a callback added to one copy and not the other compiles, renders, and simply does nothing on the layout nobody was looking at. So the wiring moved to Slint globals. A panel reads the global and calls the global; Rust hooks the global instead of the window; and the instantiation in the column is now the panel's name and a pair of braces — every one of the ten children of the column, with no property that differs by placement left to supply. There is a global per panel family rather than one for all of them, and the reason is an import cycle. Each panel's model struct — `ParamRow`, `MaskRow`, `HistogramView` — is declared in the panel's own file, so a single global holding `[MaskRow]` and `[ParamRow]` would have to live in a file importing `masks.slint` and `adjust.slint` while both imported the global back, which Slint rejects. Breaking that needs six model declarations relocated, which is a change to the data model and not to the plumbing this is about. A global beside the panel it serves also lets each name drop the prefix it was carrying only because the window root is one flat namespace: `root.spot-radius` is `Repair.radius`, and `root.peaking-on` is `Peaking.showing`. `session.slint` is new and holds the two facts every family needs and none of them owns: whether there is an open photograph to edit, and which mode the view is in, with the three readings of the mode derived once instead of at each of the dozen places that tested one. `ViewMode` moves there from `adjust.slint`, where it was only ever a lodger. Nothing on screen changes. What is not here: the tool rail and the status strip still take their properties at the instantiation, because they are drawn once and N9 does not copy them; the preset sheet's own state stays on the window, because the library grid opens the same sheet and a global cannot bind the window's state — which is why `Transfer.open-presets` is handled in `presets.rs`, beside the summary it already had to compute.

|
|
//! `dr-types` and is tested headless, [`render`] pushes it into window

//! across the boundary and decides nothing about what a setting *means*.
|
|
//!
|
|
//! # Every edit saves
|
|
//!
|
|
//! There is no Save button. A settings page with one has to answer what
|
|
//! happens when the window closes with the button untouched, and every
|
|
//! available answer is bad: discarding silently loses work, prompting turns a
|
|
//! preference change into a dialogue, and saving anyway makes the button a
|
|
//! decoration. Writing on each edit removes the question — the file is a few
|
|
//! hundred bytes, written by rename, and the user's last action is always what
|
|
//! is stored.
|
|
//!
|
|
//! A failed write is surfaced rather than swallowed, because the whole
|
|
//! contract of this page is that what it shows is what is saved. If the disk
