A group dragged to the window edge where an iconic column sits showed the
edge line and an outline around the column. The edge line is drawn just
inside the window, so it lay in the column's body, and paint_drop_line
outlines the iconic column a line lies in. That outline is for drops into
the column; a window-edge drop docks beside it, so it now shows the line
alone.
* docking: menu key equivalents reach the focused text field of a native window
On macOS the menu bar takes key equivalents such as Cmd+C and Cmd+V before
the key window sees them, and an app's menu glue reports them in the main
window's input, where they ran on the document even while a text field in a
floating panel's own window had focus. Each native window notes its text
focus as it draws. While the window with the keyboard has a focused field,
the main window's input hands that window the keys a text field acts on
(Cmd+C/X/V/A, Cmd+Z and Shift+Cmd+Z, Cmd with the arrows, Cmd+Backspace and
Cmd+Delete, and Copy, Cut and Paste events); Cmd+C and Cmd+X arrive as Copy
and Cut, and Cmd+V asks the window for the clipboard text. Other command
keys stay with the main window, and nothing moves while input is blocked.
typing_window and send_keys expose the same routing to menus that run
commands themselves.
* docking: typing_window answers between frames with the last frame's focus
* docking: a dragged native window fades only while a drop target is highlighted
The dragged window stays opaque over empty space and goes to 75% only
while the bar, only-tab or only-tab-row drag shows a drop preview.
paint_group_drag reports whether it highlighted a target; end_cross keeps
that for the next frame, since the dragged window sets its opacity before
the preview is drawn.
* docking: a dragged in-window floating window fades only while a drop target is highlighted
The rule for native windows covers in-window floating windows too. A
title bar drag draws its window at DRAG_OPACITY (75%) while the drag
highlights a drop target, and opaque over empty space and after a drop,
Escape or focus loss. finish_group_drag keeps paint_group_drag's result
for the next frame, since the window draws before the preview.
FloatingFrame takes an opacity for the whole frame, contents included.
* docking: a title-bar drag also fades over a preview the host draws
* docking: keep native palettes shown while the app is inactive
Palettes no longer hide when none of the application's windows has focus.
They drop to WindowLevel::Normal while the application is inactive, so
they do not cover other applications, and go back to AlwaysOnTop when it
is active again. Files dragged from another application reach them, OS
sheets attached to them stay open, and they stay shown, dimmed, while an
app modal blocks input.
* docking: on Windows an inactive app's palettes go behind other windows
* docking: the viewer level test expects the inactive palette level
AppKit reports a native window's new place as soon as a move is
commanded, but measures the pointer events it sends against where the
window server had the window, which can be a move behind. Placing the
window from those events made it overshoot and step back while the
cursor moved smoothly.
On macOS the window now goes to NSEvent::mouseLocation, flipped against
the primary screen's height and divided by egui's zoom factor, less the
pressed point; drop targets are hit at the same point. Other platforms
keep placing the window from the frame's pointer move.
The cursor source is a DesktopCursor the test harness fixes. NativeHost
can tell the cursor (tells_cursor) and measure a window's pointer events
against its place some frames back (stale), through window_pointer.
A group bar drag to a dock band named by one of the moving panels, such as the window edge of the column the group heads, anchors on another panel of that column, as a tab drag does; with none, the drop is a no-op. Before, the model rejected the move and the drop did nothing.
Drops on the bands along the layout's outer edge (a new dock, a new outermost column, the outer edge band) preview the line along that edge instead of the rect the panels take; drops beside groups keep the rect. The window-edge column line sits inside the window, like the new-dock line.
With new_dock_zones (and without side_edge_zones), the body of a frame or
floating group that takes no tabs is no drop target, whatever its
accepts_splits. A floating window released there stays floating and a
docked panel floats as over empty space; the outer edge band, dock columns,
new docks and drops beside other groups still dock. Without new_dock_zones
the whole canvas body still goes to the nearest of drop_edges.
* docking: a minimized native window shrinks to its bar
A floating window shown in its own OS window kept its full size when
minimized, with an empty body under the tab strip. Minimizing now sizes
the OS window to its bar and the tab strip of its only group, at the
same width and top-left corner, and fixes its height with the window's
min and max inner size; expanding restores the saved size. The layout's
native and in-window rects keep the expanded height: the collapsed
height the window reports is not recorded, its position and width are.
* docking: a minimized native window's limits change before its size, and follow its bar height
* docking: fade a dragged native window only when the drag can dock
* docking: narrow the outer edge band to the canvas column and add DockStyle::drop_edges
* docking: drop_edges defaults to all sides; the docking profile's outer band takes only its top and bottom
* panes: preview the slot a dragged pane docks in, also while floating
* docking: a drop that changes only sizes is a no-op; a lone floating group's header drag looks through its window
* docking: a drop beside a frame too narrow to halve takes the room from beyond its divider
* panes: the dock preview counts a pane its drop reveals, and a side pane stays inside the host
With SidePolicy::OneSlot a drop can reveal a pane the frame hides, so the landing slot is
worked out from every open pane. A side pane is no wider than the room the panes outside it
leave, as the preview assumes; egui placed a wider one partly beyond the host's edge.
* docking: anchor an outer edge drop on the area it shows
The edge band and window.panel.dock to an outer edge anchor on the canvas only where the edge area narrows to the canvas column, else on a panel that is not protected, so tree order no longer decides the frame. The renderer tries the drop and offers the band only when it wraps the panels the band shows. A top (bottom) edge also narrows a split of rows to its first (last) row when only that row holds the canvas. to_actions takes the permissions, and FloatSpace records side_edge_zones.
* docking: a sized split gives the new frame its minimum or saved width
* docking: keep a native window opaque during a float-only drag
* docking: DockCommand::to_actions keeps its signature; to_actions_with takes the permissions
FilmCraft calls to_actions. Without permissions no panel is protected, so an outer edge dock
wraps the part between the docks, as before.
* docking: keep a tab's focus outline after Space or Enter
A focused tab activated from the keyboard reported a click, which marked its
focus as pointer focus and hid the outline. Only a primary pointer click marks
it now. The group header and DockArea::monitors docs say how a header widget
starts a drag and where an eframe app gets its monitor list.
* docking: name the area id in the group header's begin_drag note
* ui: panes::Rail, an icon strip that opens one task pane at a time
* ui: panes: a docked pane can go without its title bar
* ui: panes::Rail review fixes
* ui: panes: a docked pane's resize edge works on both sides of the line
The edge band and window.panel.dock to an outer edge anchor on the canvas only where the edge area narrows to the canvas column, else on a panel that is not protected, so tree order no longer decides the frame. The renderer tries the drop and offers the band only when it wraps the panels the band shows. A top (bottom) edge also narrows a split of rows to its first (last) row when only that row holds the canvas. to_actions takes the permissions, and FloatSpace records side_edge_zones.
With SidePolicy::OneSlot a drop can reveal a pane the frame hides, so the landing slot is
worked out from every open pane. A side pane is no wider than the room the panes outside it
leave, as the preview assumes; egui placed a wider one partly beyond the host's edge.
* docking: drop targets follow the pointer over the whole group
Outside side_edge_zones, a group body's outer third on each side docks
beside it and the middle joins as a tab; at a corner the relatively
nearer side wins, and a group that takes no tabs maps its whole body to
its edges. Dock-column groups get the same zones: top and bottom stack,
left and right make a column. Border bands (seam, column edge, new
dock, root edge) are 28 pt and reach only 4 pt into a tab strip that
takes tabs.
Previews are a drop_line_width line along the edge a drop docks to, or
the whole group's outline with a light fill for a tab join, for tab and
group drags alike. side_edge_zones keeps its 40 pt picture-frame zones,
overlay and previews (SIDE_EDGE_ZONE_DEPTH).
DockStyle: side_zone_fraction replaces zone_depth; new column_edge_band
and drop_line_width; edge_band, seam_band and new_dock_band default to
28.
* docking: document the drop zones, bands and previews
* docking: dock groups and the outer edge band keep the split-tree sizes with side edge zones
* docking: drop zones for hosts that resolve drops, lines kept in view, stripless dock groups
resolve_drop_by and DockStyle::zone_rule give hosts the dock area's zones and previews.
A stack line on an edge scrolled out of a dock column shows at the view's edge, and a dock
group without a tab strip takes its zones from the top of its body. A style needs a drop
line wider than zero and a side zone fraction of at most one half.
* docking: blocking input hands the keyboard from a native window to the main window
* docking: the keyboard goes to the main window only if a native window still has it after a short wait
* docking: route app drags in panel bodies across native windows
While an app's drag that began in a panel body lasts, the owner window's
input hook sends pointer moves over another of the app's windows to that
window in its coordinates (PointerMoved, PointerGone, and the primary
release), and the owner sees the pointer gone there. Drop sites in the
target window see hover and release with no app changes.
* docking: wrap the body-drag docs
* docking: a stopped body-drag route takes back the events it queued
* docking: route only body drags that carry a payload, and hold the owner's release
A body drag reaches other windows only with an egui drag-and-drop
payload or when the app calls docking::route_app_drag that frame or the
last; sliders, scrollbars and other plain drags keep the owner's
pointer. When the release goes to another window, the owner's own
release waits for its next input, so a target drawn before the owner
reads the release while egui's payload still exists. A stop never
withdraws that held release.
* docking: routed and held events come before a window's own input
* docking: a held release waits for the main window's next pass, with the pointer events after it
* docking: the owner sees the pointer go in the pass its release is held
* docking: native windows ignore input while the app shows a modal
DockArea::input_blocked disables each native floating window's widgets, drops its pointer, key, text and scroll input, covers it with DockStyle::blocked_dim over a layer that takes the pointer, offers no drop targets, forwards no events and cancels its OS close request. Turning it on cancels a drag in progress.
* docking: a blocked native window also drops hovered and dropped files
* docking: blocked palettes drop to the normal window level
* docking: a blocked native window still forwards key releases
* docking: while input is blocked, activation raises the main window last
* docking: blocked palettes stay shown, and the main window comes in front on the app's return
* docking: normal floating windows come forward when the app is activated
* docking: drop windows that became palettes from the raise queue
* docking: the main window comes forward with the normal windows, in focus order
* docking: replacing the workspace cancels a drag in progress
A dock area keeps the layout it drew while a drag is in progress, with
the actions it returned. When the next layout is neither that one nor
that one with the actions applied, the app replaced or changed it, and
the area cancels its tab, group, column, window bar, native bar, divider
and cross-window drags itself. cancel_drag also ends a native window's
bar drag.
* docking: replacing the layout also ends a divider drag in a native window
* docking: an input hook and dropped files for every native window
eframe runs raw_input_hook only for the root viewport, and each native window's
dropped files arrive only in that window's input. DockArea::native_input_hook runs
an app hook on each native window's RawInput through an egui plugin, before egui
reads it, and DockOutput::window_files reports files hovered or dropped on native
windows with the window and the panel under the pointer. The test host takes
hovered and dropped files per window.
* docking: a discarded pass reports no hovered files; share hook state through a mutex
* docking: one file report per native window when its pass is discarded
* docking: panels closed one by one reopen into one group
Showing a hidden panel whose anchor is hidden too follows the chain of
hidden anchors to its far end, so a floating location no longer opens a
second window. The hidden panels the restore passed then anchor back on
the panel before them in the chain, on the recorded side, so reopening
them joins the restored panel instead of rebuilding their group or
window. A restored tab whose next tab is not in the anchor's group goes
last.
* docking: a panel beside an edge frame keeps its own location on reopen
* docking: a panel reopened through a hidden neighbour keeps its own group state; the chain stops reversing at an edge frame
* docking: viewer panels float as normal windows
DockContent::window_kind marks panels as palettes (the default) or normal
windows. A native floating window holding any Normal panel gets the normal
window level and stays shown while the app is in the background; drags
treat it as stacked with the main window by focus.
* docs: a normal window behind the main window takes drags outside it
* docking: tabs shrink before they overflow
Tabs in a narrow strip shrink, widest first, down to DockStyle::min_tab_width (54 pt at the
default font), cutting their labels with "…" and naming them in a tooltip. Only tabs that do
not fit at that width go to the overflow menu.
* docking: the drag bar narrows once the strip is narrower than the header plus the bar
* docking: floating windows stay in the app window on Wayland
The compositor reports no window positions, so native windows could not
dock again by drag or reopen where they were. The dock area detects
Wayland (WAYLAND_DISPLAY or WAYLAND_SOCKET set and a main window that never
reported its outer rect) and draws floats in-window, keeping their native
rects. DockArea::native_windows(bool) overrides the choice.
* docking: a missing DISPLAY also counts as a possible Wayland backend
* Revert "docking: a missing DISPLAY also counts as a possible Wayland backend"
This reverts commit a804afb1d3.
* docking: the Wayland session is a pure function of the environment; without a Wayland variable only a real window counts
* docking: open an unanchored panel in the first dock group or at an edge
* docking: an unanchored open prefers the end-side dock; an edge frame is a quarter wide
* docking: drop the redundant edge resize; an edge frame is already a quarter wide
* docking: an unanchored open passes over minimized groups and iconic columns
