From 76229a3601267830be0332f58f82ec16bc77a125 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?St=C3=A9phane=20D=C3=A9murget?= Date: Sat, 3 Nov 2012 22:18:42 +0100 Subject: [PATCH] overview: highlight windows on launcher hover When in the overview, if you move the mouse cursor over one of the application launchers in the dash, all the unrelated windows are dimmed both both in the window view and in the workspace view. It helps to easily understand whether or not there are already opened windows for this application, and where they are. It can also help in differentiating the windows in the overview (sometimes the thumbnails aren't precise enough to easily know which thumbnail belongs to which application). https://bugzilla.gnome.org/show_bug.cgi?id=657315 --- js/ui/dash.js | 115 +++++++++++++++++++++++++++--------- js/ui/overview.js | 11 ++++ js/ui/workspace.js | 36 +++++++++++ js/ui/workspaceThumbnail.js | 37 ++++++++++++ 4 files changed, 170 insertions(+), 29 deletions(-) diff --git a/js/ui/dash.js b/js/ui/dash.js index d367aaac9..d56913ebd 100644 --- a/js/ui/dash.js +++ b/js/ui/dash.js @@ -20,6 +20,7 @@ const DASH_ANIMATION_TIME = 0.2; const DASH_ITEM_LABEL_SHOW_TIME = 0.15; const DASH_ITEM_LABEL_HIDE_TIME = 0.1; const DASH_ITEM_HOVER_TIMEOUT = 300; +const HOVERED_APP_NOTIFICATION_TIMEOUT = 20; function getAppFromSource(source) { if (source instanceof AppDisplay.AppWellIcon) { @@ -57,6 +58,7 @@ const DashItemContainer = new Lang.Class({ this._childScale = 1; this._childOpacity = 255; this.animatingOut = false; + this.appIcon = null; }, _allocate: function(actor, box, flags) { @@ -375,9 +377,12 @@ const Dash = new Lang.Class({ this._dragPlaceholder = null; this._dragPlaceholderPos = -1; this._animatingPlaceholdersCount = 0; - this._showLabelTimeoutId = 0; + this._setHoverTimeoutId = 0; this._resetHoverTimeoutId = 0; - this._labelShowing = false; + this._userAlreadyHovering = false; + this._hoveredItem = null; + this._hoveredAppTimeoutId = 0; + this._primaryAction = true; this._container = new DashActor(); this._box = new St.BoxLayout({ vertical: true, @@ -387,7 +392,7 @@ const Dash = new Lang.Class({ this._showAppsIcon = new ShowAppsIcon(); this._showAppsIcon.icon.setIconSize(this.iconSize); - this._hookUpLabel(this._showAppsIcon); + this._hookUpItem(this._showAppsIcon); this.showAppsButton = this._showAppsIcon.toggleButton; @@ -421,6 +426,19 @@ const Dash = new Lang.Class({ Lang.bind(this, this._onDragCancelled)); Main.overview.connect('window-drag-end', Lang.bind(this, this._onDragEnd)); + + Main.overview.connect('hiding', + Lang.bind(this, function() { + this._userAlreadyHovering = false; + + if (this._hoveredItem) + this._hoveredItem.hideLabel(); + + this._setHoveredItem(null, this._primaryAction); + })); + + global.stage.connect('captured-event', + Lang.bind(this, this._onCapturedEvent)); }, _onDragBegin: function() { @@ -468,26 +486,14 @@ const Dash = new Lang.Class({ return DND.DragMotionResult.CONTINUE; }, - _appIdListToHash: function(apps) { - let ids = {}; - for (let i = 0; i < apps.length; i++) - ids[apps[i].get_id()] = apps[i]; - return ids; - }, - _queueRedisplay: function () { Main.queueDeferredWork(this._workId); }, - _hookUpLabel: function(item) { + _hookUpItem: function(item) { item.child.connect('notify::hover', Lang.bind(this, function() { this._onHover(item); })); - - Main.overview.connect('hiding', Lang.bind(this, function() { - this._labelShowing = false; - item.hideLabel(); - })); }, _createAppItem: function(app) { @@ -508,6 +514,7 @@ const Dash = new Lang.Class({ })); let item = new DashItemContainer(); + item.appIcon = appIcon; item.setChild(appIcon.actor); // Override default AppWellIcon label_actor, now the @@ -516,7 +523,7 @@ const Dash = new Lang.Class({ item.setLabelText(app.get_name()); appIcon.icon.setIconSize(this.iconSize); - this._hookUpLabel(item); + this._hookUpItem(item); return item; }, @@ -525,9 +532,9 @@ const Dash = new Lang.Class({ // When the menu closes, it calls sync_hover, which means // that the notify::hover handler does everything we need to. if (opened) { - if (this._showLabelTimeoutId > 0) { - Mainloop.source_remove(this._showLabelTimeoutId); - this._showLabelTimeoutId = 0; + if (this._setHoverTimeoutId > 0) { + Mainloop.source_remove(this._setHoverTimeoutId); + this._setHoverTimeoutId = 0; } item.hideLabel(); @@ -536,32 +543,82 @@ const Dash = new Lang.Class({ _onHover: function (item) { if (item.child.get_hover()) { - if (this._showLabelTimeoutId == 0) { - let timeout = this._labelShowing ?
