Jasper St. Pierre	a7d7f94892	screenShield: Don't hide windows until we've fully locked the shield Revert the commit that ties hasWindows to the session mode, as we need to do the "transition" manually. Instead, show/hide the sessionGroup ourselves. For optimization purposes, we also need to hide the window groups when in the overview. Ideally, these would be culled out by Clutter, but they are not from experimentation.	2014-01-31 17:57:57 -05:00
Jasper St. Pierre	427f516d45	layout: Replace SystemBackground with CSS on the systemGroup This merges the implementation of the noise texture on the lockScreenDialog and the startup animation -- they now just use the systemGroup.	2014-01-31 17:57:57 -05:00
Jasper St. Pierre	cbb88ffdbb	layout: Add sessionGroup / systemGroup to better-define layers In order to build a better transition animation from the lock screen, we need to split the world into layers, as per this reference: https://raw.github.com/gnome-design-team/gnome-mockups/master/system-lock-login-boot/system-layers2.png Everything that pertains to the user's session is in the "session group", which includes the window group, overview, message tray (for now), keyboard, OSDs, menus, etc. For implementation sake, we did not match this mockup exactly. The new layers look like this, from top to bottom: * Stage * Magnifier (clones the uiGroup) * uiGroup * overlayGroup * menuGroup * panelGroup * screenShieldGroup * sessionGroup * top_window_group * other boxes (trayBox, keyboardBox, etc.) * other groups (osdGroup, switcherPopupGroup, etc.) * overviewGroup * window_group * systemGroup The "session startup" animation now only zooms in the sessionGroup. The panel is now outside the session, as it needs to sit above the screen shield. This also means that it's not zoomed in as part of startup. I think this is OK. This also means that the lightboxes that the screen shield uses to fade out the screen have to go in a new group, above the panel. This is known as the overlayGroup, which has no relation to the old mutter group of the same name. We also change the screen shield to put the lockDialogGroup in the system group, and put the lockScreenGroup in the screenShieldGroup, which means that the layer stacking is correct. Note that we don't hide the session group in the lock screen yet, which is something I want to do. Since not a lot of items need to be in the uiGroup anymore, we've removed the Main.uiGroup fallback; others should use sessionGroup instead, when appropriate.	2014-01-31 17:57:57 -05:00
Jasper St. Pierre	71670bad3b	layout: Add different groups in the LayoutManager for discrete UI components This helps take cruft out of the uiGroup, and ensures that components remain stacked properly on top of each other. In the future, we'll use this group to ensure that grabs are ordered properly, as well.	2014-01-31 17:57:57 -05:00
Jasper St. Pierre	a2e4153fa0	background: Fix cancellable issues If we have the following sequence: cache.getImageContent({ filename: "foo", cancellable: cancellable1 }); cache.getImageContent({ filename: "foo", cancellable: cancellable2 }); cancellable1.cancel(); Then the second load will complete with "null" as its content, even though it was never cancelled, and we'll see a blank image. Meanwhile, since the second load simply appends to the list of callers for the second load, cancellable2 does absolutely nothing: cancelling it won't stop the load, and it will still receive onFinished handling. To prevent this from happening, give the actual load operation its own Gio.Cancellable, which is "ref-counted" -- only cancel it when all the other possible callers cancel. Additionally, clean up the large nested loops by splitting out duplicated code and other stuff. https://bugzilla.gnome.org/show_bug.cgi?id=722149	2014-01-31 17:57:57 -05:00
