Fix some support for EWMH hints, and fix USER_TIME support to include the 2004-07-31 Rob Adams <readams@readams.net> Fix some support for EWMH hints, and fix USER_TIME support to include the DEMANDS_ATTENTION hint. Also includes some code for implementing _NET_RESTACK_WINDOW and _NET_MOVERESIZE_WINDOW, but this is disabled pending feature thaw. * COMPLIANCE: update with new information * src/display.c (meta_display_open): add new hints to list * src/display.h (_MetaDisplay): Add new atoms to struct * src/screen.c (set_supported_hint): update the list of support hints. (set_desktop_viewport_hint): new function sets the viewport hint to (0,0) as required by the spec for WMs with no viewport support. (set_desktop_geometry_hint): new function to set the desktop size hint to the size of the display, since we don't implement large desktop support, as required by the spec. (meta_screen_resize): update the geometry hint on screen resize * src/window.c (meta_window_new_with_attrs): Initialize demands_attention state (set_net_wm_state): Set demands_attention hint in the window state (meta_window_show): If we don't pop up a window because of USER_TIME, set DEMANDS_ATTENTION on the window. (meta_window_focus): When a window receives focus, remove DEMANDS_ATTENTION hint (meta_window_client_message): Allow other apps to set DEMANDS_ATTENTION on a window. Also, if the _NET_ACTIVE_WINDOW hint includes a timestamp, use it. (update_net_wm_state): Read DEMANDS_ATTENTION state also * src/window.h (_MetaWindow): add wm_state_demands_attention bit.

Merge of all the changes on the constraints_experiments branch. This is 2005-11-18 Elijah Newren <newren@gmail.com> Merge of all the changes on the constraints_experiments branch. This is just a summary, to get the full ChangeLog of those changes (approx. 2000 lines): cvs -q -z3 update -Pd -r constraints_experiments cvs -q -z3 diff -pu -r CONSTRAINTS_EXPERIMENTS_BRANCHPOINT ChangeLog Bugs fixed: unfiled - constraints.c is overly complicated[1] unfiled - constraints.c is not robust when all constraints cannot simultaneously be met (constraints need to be prioritized) unfiled - keep-titlebar-onscreen constraint is decoration unaware (since get_outermost_onscreen_positions() forgets to include decorations) unfiled - keyboard snap-moving and snap-resizing snap to hidden edges 109553 - gravity w/ simultaneous move & resize doesn't work 113601 - maximize vertical and horizontal should toggle and be constrained 122196 - windows show up under vertical panels 122670 - jerky/random resizing of window via keyboard[2] 124582 - keyboard and mouse snap-resizing and snap-moving erroneously moves the window multidimensionally 136307 - don't allow apps to resize themselves off the screen (*cough* filechooser *cough*) 142016, 143784 - windows should not span multiple xineramas unless placed there by the user 143145 - clamp new windows to screensize and force them onscreen, if they'll fit 144126 - Handle pathological strut lists sanely[3] 149867 - fixed aspect ratio windows are difficult to resize[4] 152898 - make screen edges consistent; allow easy slamming of windows into the left, right, and bottom edges of the screen too. 154706 - bouncing weirdness at screen edge with keyboard moving or resizing 156699 - avoid struts when placing windows, if possible (nasty a11y blocker) 302456 - dragging offscreen too restrictive 304857 - wireframe moving off the top of the screen is misleading 308521 - make uni-directional resizing easier with alt-middle-drag and prevent the occasional super annoying resize-the-wrong-side(s) behavior 312007 - snap-resize moves windows with a minimum size constraint 312104 - resizing the top of a window can cause the bottom to grow 319351 - don't instantly snap on mouse-move-snapping, remove braindeadedness of having order of releasing shift and releasing button press matter so much [1] fixed in my opinion, anyway. [2] Actually, it's not totally fixed--it's just annoying instead of almost completely unusable. Matthias had a suggestion that may fix the remainder of the problems (see http://tinyurl.com/bwzuu). [3] This bug was originally about not-quite-so-pathological cases but was left open for the worse cases. The code from the branch handles the remainder of the cases mentioned in this bug. [4] Actually, although it's far better there's still some minor issues left: a slight drift that's only noticeable after lots of resizing, and potential problems with partially onscreen constraints due to not clearing any fixed_directions flags (aspect ratio windows get resized in both directions and thus aren't fixed in one of them) New feature: 81704 - edge resistance for user move and resize operations; in particular 3 different kinds of resistance are implemented: Pixel-Distance: window movement is resisted when it aligns with an edge unless the movement is greater than a threshold number of pixels Timeout: window movement past an edge is prevented until a certain amount of time has elapsed during the operation since the first request to move it past that edge Keyboard-Buildup: when moving or resizing with the keyboard, once a window is aligned with a certain edge it cannot move past until the correct direction has been pressed enough times (e.g. 2 or 3 times) Major changes: - constraints.c has been rewritten; very few lines of code from the old version remain. There is a comment near the top of the function explaining the basics of how the new framework works. A more detailed explanation can be found in doc/how-constraints-works.txt - edge-resistance.[ch] are new files implementing edge-resistance. - boxes.[ch] are new files containing low-level error-prone functions used heavily in constraints.c and edge-resistance.c, among various places throughout the code. testboxes.c contains a thorough testsuite for the boxes.[ch] functions compiled into a program, testboxes. - meta_window_move_resize_internal() *must* be told the gravity of the associated operation (if it's just a move operation, the gravity will be ignored, but for resize and move+resize the correct value is needed) - the craziness of different values that meta_window_move_resize_internal() accepts has been documented in a large comment at the beginning of the function. It may be possible to clean this up some, but until then things will remain as they were before--caller beware. - screen and xinerama usable areas (i.e. places not covered by e.g. panels) are cached in the workspace now, as are the screen and xinerama edges. These get updated with the workarea in src/workspace.c:ensure_work_areas_validated()

Still pretty buggy. * src/keybindings.c (process_keyboard_move_grab) (process_keyboard_resize_grab): add gruesome wireframe hacks * src/display.c (meta_display_end_grab_op): end wireframe (meta_display_begin_grab_op): begin wireframe * src/effects.c (meta_effects_end_wireframe) (meta_effects_update_wireframe, meta_effects_begin_wireframe): routines to draw the wireframe stuff * src/window.c (window_should_be_showing): hide window when doing wireframe, commented out as it breaks grab * src/window.c (meta_window_refresh_resize_popup): handle wireframe * src/screen.c (meta_screen_new): create a screen->root_xor_gc for use in drawing wireframes * src/frames.c (meta_frames_push_delay_exposes): repaint everything before we delay

Merge of all the changes on the constraints_experiments branch. This is 2005-11-18 Elijah Newren <newren@gmail.com> Merge of all the changes on the constraints_experiments branch. This is just a summary, to get the full ChangeLog of those changes (approx. 2000 lines): cvs -q -z3 update -Pd -r constraints_experiments cvs -q -z3 diff -pu -r CONSTRAINTS_EXPERIMENTS_BRANCHPOINT ChangeLog Bugs fixed: unfiled - constraints.c is overly complicated[1] unfiled - constraints.c is not robust when all constraints cannot simultaneously be met (constraints need to be prioritized) unfiled - keep-titlebar-onscreen constraint is decoration unaware (since get_outermost_onscreen_positions() forgets to include decorations) unfiled - keyboard snap-moving and snap-resizing snap to hidden edges 109553 - gravity w/ simultaneous move & resize doesn't work 113601 - maximize vertical and horizontal should toggle and be constrained 122196 - windows show up under vertical panels 122670 - jerky/random resizing of window via keyboard[2] 124582 - keyboard and mouse snap-resizing and snap-moving erroneously moves the window multidimensionally 136307 - don't allow apps to resize themselves off the screen (*cough* filechooser *cough*) 142016, 143784 - windows should not span multiple xineramas unless placed there by the user 143145 - clamp new windows to screensize and force them onscreen, if they'll fit 144126 - Handle pathological strut lists sanely[3] 149867 - fixed aspect ratio windows are difficult to resize[4] 152898 - make screen edges consistent; allow easy slamming of windows into the left, right, and bottom edges of the screen too. 154706 - bouncing weirdness at screen edge with keyboard moving or resizing 156699 - avoid struts when placing windows, if possible (nasty a11y blocker) 302456 - dragging offscreen too restrictive 304857 - wireframe moving off the top of the screen is misleading 308521 - make uni-directional resizing easier with alt-middle-drag and prevent the occasional super annoying resize-the-wrong-side(s) behavior 312007 - snap-resize moves windows with a minimum size constraint 312104 - resizing the top of a window can cause the bottom to grow 319351 - don't instantly snap on mouse-move-snapping, remove braindeadedness of having order of releasing shift and releasing button press matter so much [1] fixed in my opinion, anyway. [2] Actually, it's not totally fixed--it's just annoying instead of almost completely unusable. Matthias had a suggestion that may fix the remainder of the problems (see http://tinyurl.com/bwzuu). [3] This bug was originally about not-quite-so-pathological cases but was left open for the worse cases. The code from the branch handles the remainder of the cases mentioned in this bug. [4] Actually, although it's far better there's still some minor issues left: a slight drift that's only noticeable after lots of resizing, and potential problems with partially onscreen constraints due to not clearing any fixed_directions flags (aspect ratio windows get resized in both directions and thus aren't fixed in one of them) New feature: 81704 - edge resistance for user move and resize operations; in particular 3 different kinds of resistance are implemented: Pixel-Distance: window movement is resisted when it aligns with an edge unless the movement is greater than a threshold number of pixels Timeout: window movement past an edge is prevented until a certain amount of time has elapsed during the operation since the first request to move it past that edge Keyboard-Buildup: when moving or resizing with the keyboard, once a window is aligned with a certain edge it cannot move past until the correct direction has been pressed enough times (e.g. 2 or 3 times) Major changes: - constraints.c has been rewritten; very few lines of code from the old version remain. There is a comment near the top of the function explaining the basics of how the new framework works. A more detailed explanation can be found in doc/how-constraints-works.txt - edge-resistance.[ch] are new files implementing edge-resistance. - boxes.[ch] are new files containing low-level error-prone functions used heavily in constraints.c and edge-resistance.c, among various places throughout the code. testboxes.c contains a thorough testsuite for the boxes.[ch] functions compiled into a program, testboxes. - meta_window_move_resize_internal() *must* be told the gravity of the associated operation (if it's just a move operation, the gravity will be ignored, but for resize and move+resize the correct value is needed) - the craziness of different values that meta_window_move_resize_internal() accepts has been documented in a large comment at the beginning of the function. It may be possible to clean this up some, but until then things will remain as they were before--caller beware. - screen and xinerama usable areas (i.e. places not covered by e.g. panels) are cached in the workspace now, as are the screen and xinerama edges. These get updated with the workarea in src/workspace.c:ensure_work_areas_validated()

Merge of all the changes on the constraints_experiments branch. This is 2005-11-18 Elijah Newren <newren@gmail.com> Merge of all the changes on the constraints_experiments branch. This is just a summary, to get the full ChangeLog of those changes (approx. 2000 lines): cvs -q -z3 update -Pd -r constraints_experiments cvs -q -z3 diff -pu -r CONSTRAINTS_EXPERIMENTS_BRANCHPOINT ChangeLog Bugs fixed: unfiled - constraints.c is overly complicated[1] unfiled - constraints.c is not robust when all constraints cannot simultaneously be met (constraints need to be prioritized) unfiled - keep-titlebar-onscreen constraint is decoration unaware (since get_outermost_onscreen_positions() forgets to include decorations) unfiled - keyboard snap-moving and snap-resizing snap to hidden edges 109553 - gravity w/ simultaneous move & resize doesn't work 113601 - maximize vertical and horizontal should toggle and be constrained 122196 - windows show up under vertical panels 122670 - jerky/random resizing of window via keyboard[2] 124582 - keyboard and mouse snap-resizing and snap-moving erroneously moves the window multidimensionally 136307 - don't allow apps to resize themselves off the screen (*cough* filechooser *cough*) 142016, 143784 - windows should not span multiple xineramas unless placed there by the user 143145 - clamp new windows to screensize and force them onscreen, if they'll fit 144126 - Handle pathological strut lists sanely[3] 149867 - fixed aspect ratio windows are difficult to resize[4] 152898 - make screen edges consistent; allow easy slamming of windows into the left, right, and bottom edges of the screen too. 154706 - bouncing weirdness at screen edge with keyboard moving or resizing 156699 - avoid struts when placing windows, if possible (nasty a11y blocker) 302456 - dragging offscreen too restrictive 304857 - wireframe moving off the top of the screen is misleading 308521 - make uni-directional resizing easier with alt-middle-drag and prevent the occasional super annoying resize-the-wrong-side(s) behavior 312007 - snap-resize moves windows with a minimum size constraint 312104 - resizing the top of a window can cause the bottom to grow 319351 - don't instantly snap on mouse-move-snapping, remove braindeadedness of having order of releasing shift and releasing button press matter so much [1] fixed in my opinion, anyway. [2] Actually, it's not totally fixed--it's just annoying instead of almost completely unusable. Matthias had a suggestion that may fix the remainder of the problems (see http://tinyurl.com/bwzuu). [3] This bug was originally about not-quite-so-pathological cases but was left open for the worse cases. The code from the branch handles the remainder of the cases mentioned in this bug. [4] Actually, although it's far better there's still some minor issues left: a slight drift that's only noticeable after lots of resizing, and potential problems with partially onscreen constraints due to not clearing any fixed_directions flags (aspect ratio windows get resized in both directions and thus aren't fixed in one of them) New feature: 81704 - edge resistance for user move and resize operations; in particular 3 different kinds of resistance are implemented: Pixel-Distance: window movement is resisted when it aligns with an edge unless the movement is greater than a threshold number of pixels Timeout: window movement past an edge is prevented until a certain amount of time has elapsed during the operation since the first request to move it past that edge Keyboard-Buildup: when moving or resizing with the keyboard, once a window is aligned with a certain edge it cannot move past until the correct direction has been pressed enough times (e.g. 2 or 3 times) Major changes: - constraints.c has been rewritten; very few lines of code from the old version remain. There is a comment near the top of the function explaining the basics of how the new framework works. A more detailed explanation can be found in doc/how-constraints-works.txt - edge-resistance.[ch] are new files implementing edge-resistance. - boxes.[ch] are new files containing low-level error-prone functions used heavily in constraints.c and edge-resistance.c, among various places throughout the code. testboxes.c contains a thorough testsuite for the boxes.[ch] functions compiled into a program, testboxes. - meta_window_move_resize_internal() *must* be told the gravity of the associated operation (if it's just a move operation, the gravity will be ignored, but for resize and move+resize the correct value is needed) - the craziness of different values that meta_window_move_resize_internal() accepts has been documented in a large comment at the beginning of the function. It may be possible to clean this up some, but until then things will remain as they were before--caller beware. - screen and xinerama usable areas (i.e. places not covered by e.g. panels) are cached in the workspace now, as are the screen and xinerama edges. These get updated with the workarea in src/workspace.c:ensure_work_areas_validated()

Update constraints code to support the new _NET_WM_STRUT_PARTIAL EWMH 2003-06-10 Rob Adams <robadams@ucla.edu> Update constraints code to support the new _NET_WM_STRUT_PARTIAL EWMH draft specification. See #86682. Also, fix a bug involving work area invalidation on metacity startup. Fix for #108497. Finally, some minor fixes for full screen windows. * src/window.h: Add new MetaStruts structure to store strut rects for a window. Remove has_struts and do_not_cover flag, and support new MetaStruts instead of the four ints. * src/window.c (meta_window_new): change initialization to work with new struts. Also, move meta_window_update_struts call to after the workspaces are initialized to fix #108497. Remove do_not_cover and related code. (process_property_notify): add strut_partial (update_struts): change function name to meta_window_update_struts and expose in external MetaWindow API. Support partial width struts and the new strut rects. * src/workspace.h: add new GSLists containing pointers to all relevant struts for this workspace. * src/workspace.c (meta_workspace_new): initialize the list of strut rects for this workspace. (meta_workspace_free): free the strut rect lists (ensure_work_areas_validated): support new struts and new strut rect lists. Unleash the per-xinerama work areas. * src/constraints.c (get_outermost_onscreen_positions): Use the current window position along with the new per-workspace strut rects to compute the constraints that apply to a particular window. (constraint_hint_applies_func): don't do hints constraints on fullscreen windows (update_position_limits): for maximized windows use the work areas to set the position limits; for other windows rely on the struts constraints to be computed later in get_outermost_onscreen_positions (meta_window_constrain): don't apply aspect ratio hints to full screen windows * src/display.c (meta_display_open): add _NET_WM_STRUT_PARTIAL atom (meta_rectangle_equal): new helper function for MetaRectangles (event_queue_callback): #ifndef out if USE_GDK_DISPLAY not set to avoid compiler warning * src/display.h: add atom_net_wm_strut_partial, and add meta_rectangle_equal. * src/screen.c (meta_screen_rect_intersects_xinerama): change _window_intersects_ to _rect_intersects_ which is more useful now. (meta_screen_resize_func): update struts on windows with struts since struts are relative to the screen size, and this function is called when the screen size updates. * src/screen.h (meta_screen_rect_intersects_xinerama): change _window_intersects_ to _rect_intersects_ which is more useful now. * src/window-props.c (meta_display_init_window_prop_hooks): add hook for strut_partial * src/tools/metacity-window-demo.c: Support partial-width struts on the dock window tests for metacity testing purposes.

Fix some support for EWMH hints, and fix USER_TIME support to include the 2004-07-31 Rob Adams <readams@readams.net> Fix some support for EWMH hints, and fix USER_TIME support to include the DEMANDS_ATTENTION hint. Also includes some code for implementing _NET_RESTACK_WINDOW and _NET_MOVERESIZE_WINDOW, but this is disabled pending feature thaw. * COMPLIANCE: update with new information * src/display.c (meta_display_open): add new hints to list * src/display.h (_MetaDisplay): Add new atoms to struct * src/screen.c (set_supported_hint): update the list of support hints. (set_desktop_viewport_hint): new function sets the viewport hint to (0,0) as required by the spec for WMs with no viewport support. (set_desktop_geometry_hint): new function to set the desktop size hint to the size of the display, since we don't implement large desktop support, as required by the spec. (meta_screen_resize): update the geometry hint on screen resize * src/window.c (meta_window_new_with_attrs): Initialize demands_attention state (set_net_wm_state): Set demands_attention hint in the window state (meta_window_show): If we don't pop up a window because of USER_TIME, set DEMANDS_ATTENTION on the window. (meta_window_focus): When a window receives focus, remove DEMANDS_ATTENTION hint (meta_window_client_message): Allow other apps to set DEMANDS_ATTENTION on a window. Also, if the _NET_ACTIVE_WINDOW hint includes a timestamp, use it. (update_net_wm_state): Read DEMANDS_ATTENTION state also * src/window.h (_MetaWindow): add wm_state_demands_attention bit.

(fixes #142198) * src/keybindings.c (handle_toggle_desktop): access showing_desktop through the active workspace * src/screen.c (meta_screen_new): remove initialization of screen->showing_desktop, (meta_screen_update_showing_desktop_hint): rename and make not static and access showing_desktop through the active workspace, (queue_windows_showing): replace meta_display_list_windows() with screen->active_workspace->windows, (meta_screen_minimize_all_on_active_workspace_except): renamed from meta_screen_minimize_all_except since it now only works on the active workspace, (meta_screen_show_desktop, meta_screen_unshow_desktop): access showing_desktop through the active workspace * src/screen.h (struct _MetaScreen): remove showing_desktop field, (meta_screen_minimize_all_on_active_workspace_except): rename from meta_screen_minimize_all_except, (meta_screen_update)_showing_desktop_hint): export this function too * src/window.c (maybe_leave_show_desktop_mode): access showing_desktop through the active workspace and use new name for meta_screen_minimize_all_on_active_workspace_except, (window_should_be_showing): access showing_desktop through the active workspace * src/workspace.c (meta_workspace_new): initialize workspace->showing_desktop, (meta_workspace_activate_with_focus): add note that old can be NULL, update showing_desktop_hint if different on this workspace than the previous one * src/workspace.h (struct _MetaWorkspace): add showing_desktop field
