I was wondering if there is a function in pyqt5 that works similarly to the basic "input()" method from Python, only that it waits for an interaction with the GUI, like i.e pressing a button.
So instead of writing something in the console, the user presses a button to relay information.
Since this question has been associated with the wrong one before I'll be clearer: I do not mean to control the GUI via the Python console.
I want my program to wait for the user to trigger an event (i.e by pressing a button), in that sense the program asks an input that is the users interaction with the GUI.

Is it possible to detect if user quit the terminal/command line by pressing X button and take actions before that for example some cleanup or asking user whether he wants to save data?
In NSIS, on a custom page, I want to skip the page when the user presses the Cancel button, but I want to exit the installer (with confirmation) when the user presses the window's X button. How do I do that?
Currently, by using Modern UI and custom abort function, I get the same function called regardless of which of the two buttons is pressed.
This is not normal installer behavior and I would not recommend that you try to implement this.
If you still want to try I guess it might be possible with the ButtonEvent plug-in or the WndSubclass plug-in...
I write automated tests for a website. One of the tests needs to press Ctrl+S and type some letters to save a webpage including CSS/JS. The test should require Firefox to have window focus for those several seconds to be able to type the filename and click "Save" (currently XDoTool is used for pressing keys and clicking the mouse).
Sometimes I run the tests on my computer. I don't want to occasionally type something or change the window focus while the page is being saved, so I want to prohibit changing focus for those several seconds when those mouse clicks/key presses are running.
It's not possible to do it at the Webdriver level (a tool that I use for controlling the browser), so I think I should do it at the OS level. Can I prohibit the user from changing window focus or typing anything for a period of time? It may look like:
prohibit user from typing keys/change window focus
save page
allow user to type/change window focus
I guess that another way to achieve the desired effect would be to run Firefox and your automated tests on a nested X server (xf86-video-nested/Xephyr/Xnest).
$ Xnest :1
$ export DISPLAY=:1.0
$ firefox http://something/to/test &
$ your-test-script
Since the nested X server has it's own idea of the focused window, moving the focus on your desktop shouldn't affect it.
(If you don't actually need to see the test progressing, you could use a dummy X server (xf86-video-dummy/Xvfb/Xfake) instead)
I'm working on a I/O verification tool based on Linux in a game project. It is written in C++, and,since using the same I/O module as our game, it's based on OIS 1.2. Thus, though all I need is to print users' inputs on the console, I still need to create a window for OIS.
So here comes my question: How can I create a mapped window while it is still invisible and processes keyboard events?
I can't unmapped the window in that it won't process any keyboard event anymore. I also can't find function for show/hide a window.(maybe I search through a wrong diretion...)
My little tool works fine now except there is a stupid top-level empty window which needs to be focused for processing keyboard events...
Any advise is welcomed.
Thanks!!!
After reading this post: Linux/X11 input library without creating a window,
I realized my problem was that I misunderstood the philosophy of X11. All I need to do is simply pass the root window handle to OIS, and set the x11_grabkeyboard flag as true. The only drawback is maybe I can hardly debug my program with gdb since the keyboard is grabbed...
Though my situation is solved, there is one thing left.
Every article I read said an InputOnly window won't be visible and is capable for handling input events, while my InputOnly window is absolutely visible after mapped...
Maybe it's my Linux, or again, a misunderstanding...
My problem is very simple, but implementation can be hard!
I want that my application (Windows Application:: Visual C# .net) is launched whenever the user uses some keys combinations (on his keyboard).
For example it types Ctrl+W+W and my application is launched, that's all, I want the simplest implementation, less code, memory...
Thanks :D
You would need to write a keylogger type application in conjunction with your app which monitors for keyboard events. Once your specific shortcut is triggered you could then load your application.
See here for information on how to capture keystrokes.
Create a shortcut to the application, and assign a hot-key combination to the shortcut. Depending on the O/S, not every keystroke combination can be assigned to a shortcut, e.g. you may be able to assign Ctrl+Alt+W but not Ctrl+W+W.
On Windows, you can create a shortcut (on the desktop) to your application.
When you open the properties of the shortcut, on the second tab (labeled "Shortcut"), you can assign a shortcut key. But you can use only Ctrl+Alt+key shortcuts.
I don't think this is possible in the way that you framed this question. What is possible, however, is to have your application run automatically on startup without showing any forms, have it hook into Windows to monitor all keystrokes (I'm not sure how to do that part, exactly) and then show a form when the user presses a particular sequence of keys.
So in other words, your application would have to be running from the time Windows starts, but only show itself (make a form visible) when the user clicks a particular key sequence.
Update: here is a link to an article that discusses how to do global keystroke capture using C#: http://blogs.msdn.com/toub/archive/2006/05/03/589423.aspx.
