I am developing an extension on Firefox's Addon SDK (v1.10).
My extension has a toolbarbutton that updates a small badge to its left based on the contents of the active tab.
Problem
When there is more than one window open, the toolbarbutton gets updated to the value of the active tab, regardless of whether or not it is on the same window. This means that the non active window's toolbarbutton is getting updated with data coming from a different window.
Having access to the tab object from where the data comes from, is there a way to identify the window object the tab is attached to?
It would be the opposite of this method described here.
Looking at the SDK source code (namely packages/api-utils/lib/tabs/tab.js), a tab object actually has a window property. I tested it and this works indeed:
console.log(require("tabs").activeTab.window.title);
Not sure why this property isn't documented, probably a documentation bug.
Would this be the active window? You can get a window object for the current active window using
windows.browserWindows.activeWindow
Docs: https://addons.mozilla.org/en-US/developers/docs/sdk/latest/packages/addon-kit/windows.html#browserWindows
The window object has a list of tabs currently open in it:
https://addons.mozilla.org/en-US/developers/docs/sdk/latest/packages/addon-kit/windows.html#tabs
If you need to find a tab in a window that isn't the current active tab or window, that might be more difficult to determine. Can you provide more detail about what you're actually trying to do?

The QLPreviewPanel window has a button that will allow the user to open the quick look document they are currently previewing by launching its original application.
Is it possible to (a) disable this button for some documents and (b) learn if the user has clicked that button.
My problem is that some of the QLPreviewItem objects I'm passing to QLPreviewPanel are actually placeholders that aren't intended to be opened, while others are temporary documents that get created spontaneously.
In the later case, I normally delete these when the preview is done, but obviously I don't want to do this if the user has opened them in an application.
I've looked at the API for QLPreviewItem, QLPreviewPanel, and QLPreviewPanelDelegate and don't see any notifications or messages that occur when the user opens an item.
If there's no API, I might just try to hack the UI by searching the QLPreviewPanel for an NSButton and hooking its action, but I don't like hacks and I'm sure this would be a fragile one.
When I am debugging frontend work, I frequently have multiple Inspector windows open at the same time, each inspecting a different page. As I change Inspector windows, I would like the displayed tab or window to follow me. In other words, I would like the browser to always automatically change to the page I am inspecting; I do not want to change Inspector windows, then go to the browser and find the corresponding tab or window myself.
Is this possible in Firefox? Is it possible in any browser?
(I realize I could dock the Inspector to each tab or window. I do not want to do that because I use the multiple Inspector windows side-by-side for comparison.)
While I am not aware of any way to switch to the target browser tab when selecting a given inspector window, you can certainly do it the other way around:
Say you have 3 tabs opened, and you have opened devtools for each them, in window-mode (undocked). Now, whenever you select any of these 3 tabs, if you just hit F12 (or ctrl+shift+I/cmd+alt+I), then the corresponding devtools window will be brought to the front.
That's an easy way to keep track of which devtools window is linked to which browser tab.
Now, doing this the other way around would require a new feature to be implemented. This can't really be automatic (or at least hidden behind a config of some sorts) because it could be considered frustrating to some users, having their current tab being switched away from each time they click in a devtools window.
I have filed this bug to get it done: https://bugzilla.mozilla.org/show_bug.cgi?id=1163646
I'd like to make an application which user can drag and drop tab to make a new window contains
a tab control user holds. What i am looking for is the exact same functionality of Google
Chrome browser for window and Internet explorer 9. Both Applications create a new window if
if user drags and drop a tab out of original window. and vice versa.
How do i do this? Any advice or sample code will be appreciated
It's not a simple task, but if you work through it bit by bit...
Most tab controls will allow you to detect mousedown (and maybe even drag) and when the cursor is moved away from the tab row, you create a new window with a single tab (and maybe a frame depending on what you want).
When they drop, show the rest of the frame as required.
As for moving the content, this depends on your application layout but it can be as simple as changing the container of a control (SetParent()) or the destination of a render.
You can also just drag an "image" of the tab and only create the window when they drop.
Getting any more detail than this is going to be preety much impossible without specifics (and you actually accept an answer).
I am working on a utility application that controls other running applications. On certain input event my application displays a window, user can pick some operation from the window, the window disappears and control returns to the previous app. My problem is that clicking in my app’s window activates my application, thus removing focus from the previous application’s window. I can re-activate the previous application when my window closes, but I’d rather keep the original application activated all the time. Is that possible?
It's quite easy to to, just make your window an instance of NSPanel (a subclass of NSWindow), and set it as non-activating in Xcode/IB (or create it programatically, with NSNonactivatingPanelMask in the style mask).
One idea would be: while your app is running, try to keept track of the active window in the system.
After you activate your app and click the command button, restore the previous active window.
This is only an idea, I don't know how to do it on mac.
I have a desktop application written in Ruby that is using GTK2. It's just a small test application to play with GTK2, but I'm having problems achieving what I want to do. Is there any way using GTK2 to get at the titlebar (apart from setting the title), specifically to either add a button to it (beside the min/max/etc, B in the below diagram) or to add an option to the menu that pops up when you click the icon on the titlebar (A in the below diagram)?
I'm thinking there might not be because GTK is meant to work with many many different window managers, but I just wondered if there was. As a side question, what event does clicking the 'cross' button fire? At the moment if the user clicks that the window disappears but the program doesn't end - I need to capture that event and quit the program.
Thanks for any help, including hitting me over the head and telling me how silly I am.
Note that this is possible in GTK 3.10 and up, by using gtk_window_set_titlebar(). It replaces the window manager's title bar with a custom one. GtkHeaderBar is a good custom title bar class to use.
You can't, however, make it look just like the window manager would, because you won't know which window manager the user is running.
No, the title bar is owned by the window manager and you will typically not have direct access to it.
When the user tries to close the window by clicking the window manager's button, the window will receive the delete event.
