QQKey 0.2.1

Fixes a deadlock that froze the whole app when opening the settings window, and makes command
insertion both quicker and safer.

QQKey is a keyboard launcher for Windows that inserts commands into your prompt instead of
running them. Press Alt+Q in any window, search by command text, English keyword, or your own
language, then Enter — the command lands in the terminal with the caret waiting at the first
parameter. You press Enter yourself.

Fixed

• Opening settings from the launcher footer or the tray menu froze the entire app. The settings
  window came up blank white, the launcher stopped responding even to Esc, and the only way out was
  Task Manager. Creating a webview hands the request to the event loop and then waits for a reply —
  but both of those entry points already run on the event loop thread, so the main thread ended up
  waiting for itself. The white window was a real window whose WebView2 could never finish
  initialising, because the callback that would have completed it needed the very message loop that
  was blocked. This is a documented WebView2 limitation (wry#583).
  The global shortcut Alt+Shift+Q was never affected — its callback does not travel through the
  event loop — which is exactly why the bug stayed hidden for so long.

Changed

• Text is inserted as soon as the target window is genuinely in front, rather than after a fixed
  40 ms wait. SetForegroundWindow only reports that the request was accepted; the switch itself
  happens asynchronously, so something has to wait. The old fixed delay was wrong in both directions.
  Usually the foreground had already switched within a couple of milliseconds, and the remaining
  delay was paid on every single insert. Meanwhile a window being restored from minimised sometimes
  needed longer than 40 ms, and the text quietly landed somewhere else. QQKey now polls until the
  target really is the foreground window; the usual wait drops from 40 ms to roughly 10 ms.
• If the original window never comes back to the front, nothing is typed at all. Previously the
  text was sent regardless. The insert now fails after 400 ms, the launcher reappears, and the
  message states explicitly that no text was sent — so you are never left hunting through other
  windows for a stray half-typed command.

Install

Windows 10 or 11, x64. Either installer works — the MSI for a plain install, the NSIS setup if you
prefer the smaller download.

The installers are not code-signed, so SmartScreen will show "Windows protected your PC" and
hide the button behind More info → Run anyway. That is what Windows does with any unsigned
binary from a publisher it has not seen before. Verify your download against the hashes below:

QQKey then lives in the tray with no visible window. Alt+Q opens the launcher, Alt+Shift+Q the
settings window. Start automatically at sign-in is a checkbox in settings, off by default.

QQKey 0.2.0

Adds a Simplified Chinese UI and changes the licence from MIT to GPL-3.0.

QQKey is a keyboard launcher for Windows that inserts commands into your prompt instead of
running them. Press Alt+Q in any window, search by command text, English keyword, or your own
language, then Enter — the command lands in the terminal with the caret waiting at the first
parameter. You press Enter yourself.

What's new

• 简体中文 UI, bringing the interface to 7 languages. The launcher, settings window, tray menu,
  startup-failure dialog and backend error messages all carry it, and all 104 built-in commands are
  described and searchable in every one of the seven.
• System-locale detection now tells Simplified from Traditional Chinese. zh is the only language
  whose script and region subtags are read: Hans/CN/SG/MY map to zh-Hans, and every other
  zh — including zh-TW, zh-HK, zh-MO and a bare zh — maps to zh-Hant.
• Searching in one language still finds commands described in another. Built-in entries match against
  the union of all seven languages' keywords, so switching the UI to English does not hide the
  commands you used to find by typing Chinese.
• Both installers now show the full licence text during installation, and the executable carries a
  copyright notice in its file properties.

Licence change

From this release on, QQKey is licensed under the GNU GPL v3, not MIT. Use it, read it, change
it, run it at work — all fine. But anything you distribute that is built on it has to ship under
GPL-3.0 too, with its source.

Version 0.1.0 was published under MIT. That grant cannot be withdrawn and still covers those
commits; the change applies from 0.2.0 onward. The 0.1.0 installers have been removed from that
release, so the only binaries offered here are GPL-licensed ones.
