From 2812c21322870970c60021d4d4577e95fbb9bdcd Mon Sep 17 00:00:00 2001 From: Colin Walters Date: Wed, 9 Sep 2009 21:14:31 -0400 Subject: [PATCH] Allow popup menu to be persistent, and support direct window selection When the user click+hold+release over the icon, the effect we want is for the menu to stick around. Also, allow the user to mouse over the actual windows and select them directly. If the user mouses over a window, reflect that in the menu. https://bugzilla.gnome.org/show_bug.cgi?id=594699 --- js/ui/appDisplay.js | 80 +++++++++++++++++++++++++++++++++++++-------- js/ui/workspaces.js | 1 + src/shell-menu.c | 77 ++++++++++++++++++++++++++++++++++++++++--- src/shell-menu.h | 2 ++ 4 files changed, 142 insertions(+), 18 deletions(-) diff --git a/js/ui/appDisplay.js b/js/ui/appDisplay.js index 3662d6faa..9caf83475 100644 --- a/js/ui/appDisplay.js +++ b/js/ui/appDisplay.js @@ -489,6 +489,8 @@ WellMenu.prototype = { _init: function(source) { this._source = source;
