There was a problem hiding this comment.
I think this slightly changes the behavior from accepting 'q' to 'q' and 'Q' (shift-q). But I'm fine with this, personally.
edit: oh, also ctrl-Q, as you mention in the PR desc.

ac57859 qt: Fix deprecated QCharRef usage (Hennadii Stepanov) Pull request description: From Qt docs: - [`QKeyEvent::text()`](https://doc.qt.io/qt-5/qkeyevent.html#text): > Return values when modifier keys such as Shift, Control, Alt, and Meta are pressed differ among platforms and could return an empty string. - [`QString::operator[]()`](https://doc.qt.io/qt-5/qstring.html#operator-5b-5d): > **Note:** Before Qt 5.14 it was possible to use this operator to access a character at an out-of-bounds position in the string, and then assign to such a position, causing the string to be automatically resized. Furthermore, assigning a value to the returned `QCharRef` would cause a detach of the string, even if the string has been copied in the meanwhile (and the `QCharRef` kept alive while the copy was taken). These behaviors are deprecated, and will be changed in a future version of Qt. Since Qt 5.14 this causes a `QCharRef` warning if any modifier key is pressed while the splashscreen is still displayed. Fix #18080. Note: Ctrl+Q will also close the spashscreen now.

Summary: This change prevent a `QCharRef` deprecation warning if any modifier key is pressed while the spashscreen is still displayed, for Qt >= 5.14. As a side effect, Ctrl+Q and Shift+Q will also close the splashscreen now. This is a backport of core [[bitcoin/bitcoin#18101 | PR18101]] Test Plan: `ninja && src/qt/bitcoin-qt -regtest` Press Q, or Ctrl+Q or Shift+Q while on the splashscreen.
