common: add node-type.c/h (renaming ssd_part_type to lab_node_type) ssd_part_type contains several node types that are not actually part of server-side decorations (ROOT, MENU, OSD, etc.) Rename it accordingly and move it to a common location, along with some related conversion/comparison functions.

common: flesh out enum lab_edge and prefer over wlr_edges/wlr_direction I like the new common/edge.h. I don't like how inconsistently we use it. Current situation: - enum wlr_edges and wlr_direction are designed to be used as bitset, and are defined compatibly - enum lab_edge is *also* designed to be used as bitset, but incompatible with the others (LEFT/RIGHT come before UP/DOWN) - we use an inconsistent mix of all three *AND* uint32_t (usually with the WLR_EDGE constants rather than the LAB_EDGE constants), and convert between them on an ad-hoc basis, sometimes implicitly Let's clean this up: - reorder enum lab_edge to be compatible with the two wlr enums (check this by static_assert) - use TOP/BOTTOM naming rather than UP/DOWN (matches wlr_edges) - add constants for the remaining possible combinations of the 4 edges - use lab_edge for all internal edge/direction fields, consistently - add lab_edge_is_cardinal() as a sanity check before casting to enum wlr_direction, and then eliminate all of direction.c/h Instead of "enum wlr_edges direction", we now have "enum lab_edge direction" which is not that much better. At least we are now clear that we're overloading one enum with two meanings.

Convert SSD to scene nodes
2022-02-21 03:18:38 +01:00
ssd: clean up scene management Our codebase for ssd scenes has grown with a lot of technical debts: - We needed to call `ssd_get_part()` everywhere to get the scene node of a ssd part. We then needed to cast it to `wlr_scene_rect` and `wlr_scene_buffer`. This bloated our codebase and even blocked duplicated button types in `<titlebar><layout>`. - `ssd_get_part_type()` was a dirty hack. It compared parent, grandparent and grandgrandparent of a node with each subtree in the ssd to get the part type of the node. To resolve this issues, this commit changes how ssd scenes are managed: - Access scene rects and scene buffers just as a member of `struct ssd`. - `ssd_part` is now a attachment to a scene node that can be accessed via node_descriptor->data, with a new node-descriptor type `LAB_NODE_DESC_SSD_PART`. `LAB_NODE_DESC_SSD_BUTTON` is unified into it. Now the scene graph under ssd->tree looks like below. The parentheses indicate the type of ssd_part attached to the node: ssd->tree (LAB_SSD_NONE) +--titlebar (LAB_SSD_PART_TITLEBAR) | +--inactive | | +--background bar | | +--left corner | | +--right corner | | +--title (LAB_SSD_PART_TITLE) | | +--iconify button (LAB_SSD_BUTTON_ICONIFY) | | | +--normal close icon image | | | +--hovered close icon image | | | +--... | | +--window icon (LAB_SSD_BUTTON_WINDOW_ICON) | | | +--window icon image | | +--... | +--active | +--... +--border | +--inactive | | +--top | | +--... | +--active | +--top | +--... +--shadow | +--inactive | | +--top | | +--... | +--active | +--top | +--... +--extents +--top +--... When hovering on SSD, `get_cursor_context()` traverses this scene node from the leaf. If it finds a `ssd_part` attached to the node, it returns `ssd_part_type` that represents the resizing direction, button types or `Title`/`Titlebar`.

ssd: fix resizing on border corners and add <resize><cornerRange> Eliminate corner extents and instead use cursor position to map SSD borders and extents to corner contexts, with a size configurable by the <resize><cornerRange> parameter. This simplifies extent handling, eliminates bugs in the detection of corner context, and allows users to expand corner targets if they wish. Co-authored-by: Andrew J. Hesford <ajh@sideband.org>

ssd: add window drop-shadows (#1648) Add optional drop-shadows to windows using server-side decoration. Shadows can be enabled/disabled rc.xml and their appearance configured in themerc. The default is no shadows to preserve current behaviour. The shadows are drawn in fixed corner and edge buffers shared between all windows, the edges are scaled to size depending on the size of each window. Two sets of buffers are used to give the different appearances for active and inactive windows. I use separate corner/edge buffers for a few reasons: - It avoids needing to store a separate large shadow buffer per window - It avoids needing to redraw the shadows when the window is being resized - Compositing the shadows onto the desktop should be faster as there are overall fewer pixels to blend, and scaling up the edge buffers only requires reading a tiny buffer which is then replicated.

ssd: unify struct ssd_part with struct node_descriptor struct ssd_part and struct node_descriptor seem to have essentially the same purpose: tag a wlr_scene_node with some extra data indicating what we're using it for. Also, as with enum ssd_part_type (now lab_node_type), ssd_part is used for several types of nodes that are not part of SSD. So instead of the current chaining (node_descriptor -> ssd_part), let's flatten/unify the two structs. In detail: - First, merge node_descriptor_type into lab_node_type. - Add a separate view pointer in node_descriptor, since in the case of SSD buttons we need separate view and button data pointers. - Rename ssd_part_button to simply ssd_button. It no longer contains an ssd_part as base. - Add node_try_ssd_button_from_node() which replaces node_ssd_part_from_node() + button_try_from_ssd_part(). - Factor out ssd_button_free() to be called in node descriptor destroy. - Finally, get_cursor_context() needs a little reorganization to handle the unified structs. Overall, this simplifies the code a bit, and in my opinion makes it easier to understand. No functional change intended.

src/ssd: fix tiling via keybind when maximized The previous PR introduced an issue with tiling based actions like SnapToEdge and SnapToRegion using outdated SSD margin values when called via keybind while maximized. That resulted in wrong offsets for the tiled windows. This commit restores the functionality by forcing a re-calculation of the SSD margin when changing the maximized state. Thanks to @Flrian for reporting the issue via IRC.
