Looking Glass debugger of Gnome Shell provides Windows tab that lists all opened windows. Instance of such windows can be referenced from Evaluator tab after clicking, for example: [object instance proxy GType:MetaWindowX11 ...]
How can be process id of process of the selected window obtained in Evaluator tab?
There is get_client_pid() method defined in Mutter project, however it can't be called directly.
I'm just from asking something very similar on the Gnome Shell IRC, this is what I found out from the very helpful folks there:
I you open Looking Glass and click the Insert button in the upper right corner (eg. after selecting a window from the Window list), you'll get something like r(x) = ... in the evaluator (with x being a sequential number). You can then call any method on the object like so:
r(1).get_window_type()
Hope this helps!
Kind regards,
In Looking Glass:
Click on tab "Windows".
Select the desired window.
Scroll down, looking for "get_pid()".
Scroll to tab, click on "Insert" button.
Click on tab "Evaluator".
In bottom text field enter last output "r(x)" followed by ".get_pid(), for example "r(0).get_pid()", press Enter/Return.
Note the output, which is the process ID.

When I click a input button.
It show another window.
My code like this.
Click and show other window. (the window names windowB)
OpenMEMO <- remDr$findElement(using='id', value='form1:searchListTable')
OpenMEMO$clickElement()
After doing something, I want to close windowB.
But I don't know how can I do.
I try to use
#retrieve the current window handle
currWindow <- remDr$getCurrentWindowHandle()
#retrieve the list of window handles used in the session (I have 2 windows)
windows <- remDr$getWindowHandles()
#change focus to another window (windows[[2]] is windowB)
remDr$switchToWindow(windows[[2]])
#close the current window
remDr$closeWindow()
I run remDr$closeWindow().
But it closed the original window. (Actually, I want to close windowB)
Maybe I misunderstood the usage of the code.
Please give me some suggestions.
Thanks.

I'm developing a GUI in Linux (Ubuntu 16.04 - WM: Gnome) using GTK+3 and the graphic library cairo.
After clicked on a push button (Plot), using the instruction of cairo I draw a red square on a new top window where I put a GtkDrawingArea.
In this window I also put a push button (Cancel) that clicked, hide the window. In this way, if I re-push "Plot", the red square reappear.
The issue is the "x" icon present in the top bar of the window.
If (no me) a user push this x, the window disapper and if he re-push the "Plot" an error is reported.
The question is: it is possible avoid this possible cause of error?
(remove this "x" from the top bar of the window or in some way disable its functionality).
I tryed to find alone a solution and the possibility found are:
1 - Remove from the window the property of "decorated".
The top bar disapper (so also the x) but is not possible move the window on the screen
2 - Using the function gtk_window_set_deletable(window, FALSE) (used before to show the window), but the x is always there and pushing it the window is destroyed.
If you think that can be useful, I can report the code.
I'm waiting your suggestion.
Edit:
Now we know what you want to achieve: display a separate window but avoid destroying it so you can display it again. You already have in the "Cancel" button of your secondary window the logic to hide it.
The cleanest solution is to just do the same: when the user tries to close the secondary window, hide it instead. This way the user is not frustrated of seeing something that apparently doesn't work as expected. Hidden or closed, it's different for you but it's the same for the user.
So you just need to connect to the delete-event of that secondary window, and hide it. There's even no need to create a specific callback for that, GTK+ provides it for you: you just need to connect the delete-event to gtk_widget_hide_on_delete. To display the window again, just call gtk_widget_show_all on it.
Original answer:
I realize the plot
"realize" is a term that has a defined meaning in GTK+. Don't use it out of context, and try to use an alternate term if you're not talking about widget realization.
What I would like is to remove this "x" from the top bar of the window
or in some way disable its functionality.
Do you understand this is ultra annoying for a user and defeats a unified user experience? Would you like to use applications that do random different things?
Anyway, one way of disabling the closing button is to connect to the delete-event and return TRUE there to stop the propagation of the event. The button will still be there but do nothing, so you will have to kill the app to exit it.
To make the button disappear, gtk_window_set_deletable will ask the Window Manager to do that, but we'd need some code to know what's wrong with your attempt.
I tried to type a question mark into the tooptip text box of a control in the properties panel, and suddenly I got switched into code view. It turns out shift + / (or ?) now seems to be bound to a command I've never heard of which navigates to the next event handler that's referenced in XAML. So now I can't type question marks since the shortcut seems to be global.
I'd like to be able to figure out how to change this behavior, but the search bar in the keyboard options only seems to search for commands and not for shortcuts. How do I find what command is being triggered and why?
In the keyboard options dialog, press a shortcut in the Press shortcut keys box. Shortcut currently used by list will show all currently assigned commands for this shortcut:
I've got a pretty complex question for any Maya coders...
I want to utilize a drop down menu similar to that of the cmdScrollFieldExecuter's [script editor's] "Show Tooltip Help". It looks like a window that has been appended to the bottom of the inputted text with a feedback of all relative commands or strings.
Does anyone have experience with appending a similar textbox/ window/ menu to typed input, and if so, can you toss me in the right direction?
Note: I am not talking about "optionMenu".
Alternatively, is there a way to get cmdScrollFieldExecuter to reference a different array or set of strings?
A complete port of that won't be possible in vanilla Maya - You'd need to use python and QT because the built-in GUI objects (such as TextField) don't fire any events on keypresses so you won't be able to live-update as the user types.
You can almost fake the visual appearance with a window whose title bar is set to off. Use a formLayout to dock a TextScrollField inside it. You'll need to hack up some way of dismissing it since it won't have a close box -- you could put it on a timer or add an invisible button covering the whole thing which closed the window when clicked
I sometimes have a large amount of query windows open in SSMS 2008.
Is there a keyboard shortcut to navigate between open query windows? Go to previous/next open query window?
I know there is Ctrl+Tab that allows you to select a query window, but it's only helpful if you have named windows.
A challenge you'll find here is what does "next" really mean? Since you can tear off tabs, split the UI, even move tabs onto different monitors, I think "next" and "previous" lose a little meaning, unless you know what order they were opened in.
Anyway, some solutions, with older versions (based on when the question was asked) left intact:
SSMS 2008
Ctrl+F6 will switch between two most recent tabs. And honestly, Ctrl+Tab / Ctrl+Shift+Tab work like next/previous except you have to hit Tab twice (you can ignore knowing what the name of the tab in the list is).
SSMS 2012
Ctrl+F6 will cycle through open tabs in the order they are displayed, and Ctrl+Shift+F6 will cycle in the reverse direction.
Ctrl+Tab / Ctrl+Shift+Tab will open a temporary window and allow you to cycle through open queries in the order they were last opened.
In more recent decades
Ctrl+Alt+[Page Up|Page Down] will cycle through windows (as bridge_burner added), but there's a catch. This only works when the query window is active - and it will stop working if you get to a query window where, previously, you had an item in the grid selected, for example.
You can make your own keyboard shortcut, as Stuart Smith explains.
the equivalent of Ctrl+Tab in browsers for SSMS would be Ctrl+Alt+PageDown for next tab and Ctrl+Alt+PageUp for previous tab.
Here's my approach that get's me closer to coding utopia. Make sure you keep your SSMS query windows sorted by name from left to right. SQLQuery1.sql, SQLQuery2.sql, etc. These are the default names SSMS gives these tabs when you create them (by clicking New Query).
To change the current query window tab, press "alt" then "w" then "w". A window is shown listing all of your open query windows sorted by their names (which should be the same order in which you have them laid-out from left to right). Use the up and down arrow keys to highlight the tab you want to activate and press enter. Your desired tab should be open now.
This allows me to quickly change query windows while keeping my fingers on the keyboard (less mouse usage).
I know this is a very old thread, but I thought I would add one more suggestion in case someone else comes across this: Redgate's SQL Prompt comes with a nifty "Tab History" applet that gets added as a button to a toolbar. I know that that means you would have to leave the keyboard and reach for the mouse to access it, but the interface and its functionalities are worth it! Not only do you have access to the currently opened tabs (with visual mini previews of the code in each tab) but also you have access to recently closed tabs (Yes, it may save you in case you accidentally close a tab without saving your work...)
Just my two cents. Best, Raphael
I found a way to map the browser style next/previous tab shortcuts in SSMS.
Select Tools > Options. Under 'Environment' select 'Keyboard'. In the 'Show commands containing:' area type 'Window.'.
Find 'Window.NextTab'. Toggle the 'Use new shortcut in:' to 'SQL Query Editor' then enter Ctrl + PgDn in the 'Press shortcut keys:' area and select 'Assign'. Do the same steps for 'Window.PreviousTab' with Ctrl + PgUp.
