How CopyQ pastes data perfectly on respective window textboxes?

[MashukeAlam]

When I click on CopyQ items, that item got pasted in textbox of desired window. I am making a similar app using Qt5 which will be a emoji picker. I want to know how CopyQ does this thing. Sorry for bothering, any help will be appreciated. Can anyone tell me the filename and the strategy it uses to paste data?

Thanks.

CopyQ simulates Shift+Insert key press. The code is platform-dependent and may not work in some cases - e.g. on Wayland you would need to use utility like ydotool instead.

Most of the code is in src/platform/*/*platformwindow* files.
