when I play osu! on Linux the option to "confine mouse cursor to osu! window" does not work. This means that my mouse cursor will move to my other monitor when I am playing. This is an issue because if I accidentaly click one of my mouse buttons it will tab me out of osu! and I will fail the map.
I wanted to make a python script to check if the user is focused on the osu! window, and if they are, it would confine the cursor to that window, but I have no idea how I would check what window the user is focused on.

I have a program using glfw for window management and opengl for rendering. The program works on Windows and linux, and eventually Mac OSX so I want any solution to be portable.
glfw seems to either support a cursor, or getting full mouse input but not both. For example, with the cursor enabled (default) the glfwscroll_callback does nothing. If I disable the cursor, then scrolling the mouse is captured but then the user cannot see where the mouse pointer is. That's ok if I can draw the cursor myself when I want but I cannot find any function to drawcursor at a particular location.
How does the cursor work, ie what is the hardware basis for the cursor? Is there a sprite in hardware still? If it's all in software, I suppose we could draw a cursor at the current mouse location the last thing in render. But that's not convenient. For one thing if the scene hasn't changed, I shut down rendering completely to reduce power.
Is there any way to manually draw a cursor on top of the current screen so that we don't have to manage the buffers manually? Is my only option to change the logic and not render the scene if nothing has changed, but to manually draw a cursor on top of the current scene every frame?
I've made a Node/AutoHotKey script to control two computers with one mouse. I've made the cursor disappear on the first computer when using the second computer (https://www.autohotkey.com/boards/viewtopic.php?t=6167), but the mouseover event is still firing of course.
What I mean is simply if you hover over some icons on the desktop you will see tooltips, and so on.
I'm using a graphics tablet (absolute positioning), the cursor position gets captured and sent to the second computer.
I've found this method:
Found it here: https://www.autohotkey.com/boards/viewtopic.php?t=33128 (Also from the documentation: https://www.autohotkey.com/docs/commands/BlockInput.htm)
BlockInput, MouseMove ;to disable mouse interaction
BlockInPut, MouseMoveOff ;to enable mouse interaction
But it blocks mousemove completely, so that the cursor stops moving at all.
Is there any way to programmatically disable/enable mouseover (so that buttons don't change their color and tooltips don't appear, but AutoHotKey could still capture cursor position) event globally on Windows without blocking mousemove?
Is there a way when documentation popup on AS to not hide immediately after it is showed by moving mouse on some class. What I mean. I move mouse cursor above Activity class and documentation is popup is showed, but when I try to move mouse above this popup (because I have to scroll it) it disappears. I can hold ctrl and then is will not hide, but if I press on it while holdint ctrl down it will disappear (so I should move cursor above it, release ctrl and after that to start scrolling). So is there an option to change this behaviour to be like in eclipse - documentation pop up is showed and if you move mouse above it you can scroll, otherwise it is closed.
There are a lot of bugs surrounding this UI element. I'm currently having the opposite problem where it won't go away unless I manually close it. I suspect in your case, a timeout is triggering too early, or some other event is erroneously hiding the window.
This workaround may be helpful. You can explicitly pop the documentation window from the View > Tool Windows > Documentation menu option. This will cause the tool window tab to appear on the right gutter by default. Right-clicking on the Documentation tab will pop up a menu that will allow you to pin the window, or dock it permanently in the UI by disabling "Floating Mode" and optionally moving it to the other side or the bottom.
With eclipse 4.x something differs with popup window focus handling.
It is about 50% chance to lost focus when type Ctrl-e ("Quick switch editor"), Ctrl-o ("Quick outline"), etc.
The problem was with "unclutter" app which hides mouse cursor when you not move your mouse.
Looks like it send pseudo EnterNotify event to the Eclipse when it hide mouse cursor.
So if start it like
unclutter -idle 2 -noevents
problem goes away.

Other symptoms: A content assist popup opens and does not have the focus. Actually nothing seems to have the focus anymore. This consistently happens, if the popup opens over the place where the mouse cursor was before unclutter hid it. In my case the problem may have been even worse due to my use of focus-follows-mouse.
Another way to get rid of the problem: uninstall unclutter.
I want my window to be invisible most of the time, but get to top of
the screen on hotkey and hide again if the user switches to another
application.
In my hotkey handler I use
self.Show()
self.Raise()
self.Iconize(False)
and in my activate message handler
self.Hide()
self.Iconize(True)
but the window pops up on top of the screen, but remains deactivated:
it's title bar colour is a inactive one, and it flashes in the taskbar
as a window requiring my attention and it doesn't get EVT_ACTIVATE. I
tried to add self.SetFocus, but no effect.
And if I use
self.Show()
self.SetFocus()
in hotkey handler and in my activate message handler
self.Hide()
and it works okay if I deactivate my window by clicking to another
window, but if I press Alt-Tab and then invoke my window with a hotkey
it doesn't appear on top of the screen but just flashes in the
taskbar. Also I made an ability to hide it by pressing a button on it,
and if I hide it this way, it also doesn't show correctly afterwards
as in the case with Alt-Tab
you have to use a window manager to activate windows. I'm using wmctrl for that purpose (cannot find the same func. through kwin's dbus for kde).
