The WINGs view backend wl_pointer_grab was a no-op, meaning the
press-drag-release sequence for popup menus had no effect on compositor
state. On X11 this would call XGrabPointer to redirect events to the
menu window; the equivalent on Wayland is to activate the compositor
wl_pointer_grab which sets wl_state.grab_type and suppresses unwanted
cursor resets and axis leaks during the interactive drag.
Implementation: add function pointers W_WLPointerGrabFn and
W_WLPointerUngrabFn in wview_wl.c, initialized to NULL. The compositor
wires them to wl_pointer_grab / wl_pointer_ungrab at startup.
The WINGs view backend now delegates to the compositor instead of
silently returning.
The non-highlight path in paintMenuEntry only filled the row with gray
and returned early, erasing the item text, relief border, and indicator
pixmap. On Wayland this was immediately visible because the cascade+commit
on fill_rect commits every draw operation to the wl_surface.
Fix: after filling the gray background, redraw the relief border, the
item text (in black or darkGray depending on enabled state), and the
indicator pixmap for the selected item — matching what the highlight path
and makeMenuPixmap do.
Bug 1: Clicks on menu items did not select the correct item.
The WME_BUTTON_PRESS handler always called popUpMenu() which re-mapped
the already-open menu and reset highlightedItem to selectedItemIndex,
ignoring the click position. Since no motion event follows a
click-without-drag, the highlight was never corrected.
Fix: distinguish menuView vs main button events via event->window.
For menuView clicks, compute highlightedItem from click.y directly
without re-opening the menu.
Bug 2: Second popup open showed a blank gray box.
wl_unmap disabled the compositor scene node via W_ViewSceneNodeSetEnabledFn
but wl_map never re-enabled it. On re-map, the buffer was committed
to the wl_surface but the scene node stayed disabled.
Fix: re-enable scene node in wl_map before redisplay.
Reorder popUpMenu to:
1. Resize menuView before map (correct backing dimensions)
2. W_MapView first (wl_map calls wl_redisplay which fills background
and dispatches WME_EXPOSE — the old redisplay() before map was a
no-op on Wayland because wl_redisplay returns early when !mapped)
3. Copy makeMenuPixmap() output into menuView->window backing as a
safety net, ensuring the buffer has complete menu content
independent of expose-timing correctness
4. paintMenuEntry for initial highlighted item
This ensures the first visible popup buffer has all menu items
rendered regardless of the order in which the Wayland configure
and commit events arrive.
Three related fixes for WINGs popup menus on Wayland:
1. wl_client_toplevel_resize: update pending_w/h after resize
(wclient_wl.c:545-546). Without this, the configure handler sees
stale pending dimensions and creates a wrong-sized buffer,
discarding the one containing the menu text.
2. Export wl_redisplay_depth (wview_wl.c:288) so render and font
backends can detect when they are called from within a full
redisplay cycle vs. from an event handler.
3. Add cascade+commit to render_wl_fill_rect (wrender_wl.c:162-183)
and wl_draw_string (wfont_wl.c:183-208) when not inside a
redisplay cycle. This makes motion-driven highlight changes
(text color, background fill) immediately visible by compositing
up the view tree and committing the toplevel wl_surface.
WMEButton and WMEMotion are separate structs in the WMEvent union with different field layouts — u.motion.x is at a different memory offset than u.button.x. The WME_BUTTON_PRESS handler in wslider.c was calling valueForMousePoint(sPtr, event->u.motion.x, event->u.motion.y) which reads uninitialized memory on Wayland (memset zero = 0). On X11 this happened to work because the X11 event translator writes to both union members. Fix: changed all event->u.motion.x/y references to event->u.button.x/y in the WME_BUTTON_PRESS case.
Slider value changes (from click, drag, or programmatic set) call paintSlider to draw the new knob position into the pixman backing buffer, but the backing was never committed to the scene graph on Wayland. Added W_RedisplayView(slider->view) after each paintSlider call in: WMSetSliderValue, WMSetSliderMinValue, WMSetSliderMaxValue, and handleActionEvents (WME_MOTION/WME_BUTTON_RELEASE). The expose handler path does NOT get W_RedisplayView to avoid recursion.
The blue position indicator (gview — geometry view with blue-gray background,
white coordinate text) was visible during window move, but never disappeared
when the move ended.
Root cause: W_ViewSceneNodeSetEnabledFn was declared in wview_wl.c and
called by wl_unmap() to disable the view's scene buffer node, but
wl_backend.c never wired it up — the pointer was NULL.
Also: add auto-create of frame_buf for WINGs toplevel views not explicitly
reparented (switch panel, menus, gview), sync position from WINGs view on
commit, auto-realize children in wl_map/wl_map_subviews, and guard scene
node enablement against unmapped views.
Three issues prevented WPrefs from being managed by wmaker in X11:
1. W_X11OpenDisplay: XOpenDisplay("") fails; treat empty string as NULL
so it falls back to DISPLAY env var.
2. wevent_x11.c/wevent.c: MapRequest and ConfigureRequest events must
bypass WINGs view lookup (both _view_target in x11_fetch and
W_GetViewForWindow in WMHandleEvent) to reach DispatchEvent via
extraEventHandler.
3. wview_x11.c: x11_create_root must use RootWindow() not
scr->rootWin (which may be an intermediate window created by
RCreateContext for non-default visuals). Otherwise toplevel
WINGs windows are created as children of the wrong parent and
their MapRequest never reaches the WM.
WPrefs.app/main.c defaults display_name to "" (empty string).
W_X11OpenDisplay passed this directly to XOpenDisplay, but
XOpenDisplay("") is not equivalent to XOpenDisplay(NULL) — the
former fails while the latter uses the DISPLAY environment variable.
Treat empty display string as NULL so XOpenDisplay falls back to
the environment variable.
Also remove debug traces from event.c and x11_backend.c.
SubstructureRedirect events (MapRequest, ConfigureRequest) are delivered
to the root window. Since the root window has a WINGs view registered
(the WMScreen root view), W_GetViewForXWindow resolves it and
WMHandleEvent dispatches to the view handlers instead of falling through
to extraEventHandler (DispatchEvent).
This caused WINGs-based apps like WPrefs to never have their windows
managed by the WM - the MapRequest was silently consumed.
Fix: skip the view lookup for MapRequest and ConfigureRequest events so
they always reach DispatchEvent via extraEventHandler.
Menu entry painting:
- Add drawFrame() calls for 3D beveled entries (WTEX_SOLID)
- Add menu_text_clearance to text Y positioning
- Add left-side indicator drawing (radio/check/snap pixmaps)
- Add indicator X offset (MENU_INDICATOR_SPACE)
- Fix disabled+selected text color
- Fix texture-aware background clearing
- Add cascade arrow for submenu entries
Balloon tooltips:
- Implement x11_balloon_show() with text and mini-preview rendering
- Previously was a no-op stub
Clip arrows:
- Draw workspace-switching triangles on clip icon
- Previously stubbed out
Event handling:
- Add MapRequest, ConfigureRequest, ReparentNotify translation to
xev_to_wme() in WINGs/wevent_x11.c
- These WM-critical events were silently dropped, preventing new X
clients (e.g. xterm) from being managed
Selection and mapping events have mask 0 in the type table (matching
X11 semantics where they bypass event masks). Change the dispatch
check to deliver events with mask==0 to all registered handlers,
so these events are not silently dropped.
The wmeMaskForType table had WME_CLIENT_MESSAGE mapped to 0, so
WMHandleEvent never dispatched client messages to registered handlers.
The window close handler (registered with ClientMessageMask) was never
called. Set the correct mask so the deleteWindow protocol works.
The poll-based wlclient_dispatch with timeout 0 missed events that
were already buffered. Use prepare_read/read_events/dispatch_pending
which reads whatever is available on the socket without polling.
In-process WINGs clients have their own wl_display connection that
needs to be dispatched for xdg_toplevel.close to be received. Add
W_WLClientDispatchPending() and call it each main loop iteration
so protocol events reach the client-side handlers promptly.
During W_RealizeView, child views with mapWhenRealized triggered
wl_map which called wl_redisplay on the toplevel. This ran expose
handlers on a partially-realized widget tree, causing backing image
corruption from resizes during redisplay.
Fix: track realization depth with W_WL_Realizing counter. wl_map
skips redisplay when realization is in progress. After the outermost
W_RealizeView completes, trigger a single redisplay of the toplevel
to paint everything correctly.
The fill_rectangles call used view->size which can exceed the backing
image dimensions when a view is resized during realization without its
backing being reallocated. This wrote past the allocated buffer,
corrupting the heap and causing later pixman_image_composite32 crashes.
Use pixman_image_get_width/height of the actual backing instead.
Remove the verbose COMPOSITE fprintf and BAD composite warning that
were used for debugging. Keep the source/destination bounds clipping
as it correctly handles the case where view->size diverges from the
backing image dimensions during realization.
The font prefs panel crashed because wl_resize called wl_redisplay
while already inside a redisplay. This caused expose handlers to
trigger more resizes, creating unbounded recursion and memory growth
(backing images growing to 1024+ pixels wide). Skip the redisplay
from wl_resize when wl_redisplay_depth > 0 — the ongoing parent
redisplay will composite the resized child at its new size.
The previous source-only clamp was insufficient. Also check that both
src and dst have non-NULL pixel data, and clip the composite region to
the destination image dimensions to prevent out-of-bounds writes.
During W_RealizeView the WME_EXPOSE handler can trigger child resizes
that make view->size exceed the backing image dimensions. Clamp the
composite width/height to the source image actual size to prevent
out-of-bounds reads in pixman_image_composite32.
Font prefs panel crashed in pixman_image_composite32 during W_MapView
because a child view had zero width/height. Skip compositing for
zero-sized views.
In Wayland mode the X11 display is NULL. WMCreateColorWell calls
WMRegisterViewForDraggedTypes which calls XInternAtom, crashing.
Bail early when display is NULL since X11 DnD is not available.
The close button press from the compositor sends xdg_toplevel.close,
but the handler only set a flag without notifying the WINGs event
system. Synthesize a WME_CLIENT_MESSAGE with deleteWindowAtom so
the window closeAction callback fires and the app shuts down
gracefully.
Without an explicit wl_display_flush after wl_surface_commit, protocol
requests were buffered until the next event loop iteration. This caused
visual updates (like the icon position preview in WPrefs) to appear one
interaction behind.
SIGUSR2 is fundamentally unsafe in a multi-threaded compositor: library
threads (pango fontconfig) created after pthread_sigmask receive the
signal and crash. The Wayland event loop already has inotify watching
the defaults directory, so file changes are detected automatically
without any explicit signaling.
The early pthread_sigmask(SIG_BLOCK, SIGUSR2) is retained as a safety
measure to prevent stray SIGUSR2 from terminating the compositor.
The previous getppid() approach sent SIGUSR2 to the terminal process
(foot) rather than wmaker, killing the shell. Now wmaker exports
WMAKER_PID at startup and wl_send_wm_command reads it to signal the
correct process.
The Wayland event backend stub for send_wm_command was a no-op, so
WPrefs settings changes never triggered a reread in the running wmaker.
Now sends SIGUSR2 to the parent process (wmaker) on "Reconfigure",
causing wDefaultsCheckDomains to run and apply changes immediately.
