racket-webview-qt
The Qt WebEngine backend of racket-webview.
Version 0.2.3
This version replaces the shared-library/shared-memory transport with a standalone process interface.
Transport
rktwebview_prg receives line-delimited JSON commands on stdin, writes
line-delimited JSON results and events to stdout, and writes all diagnostics to
stderr. The existing command numbers and command payloads in rkt_protocol.h
are unchanged.
See STDIO-PROTOCOL.md for the transport envelope and shutdown rules.
The former shared library, shared-memory queue, and callback sources remain in the repository for comparison, but they are no longer part of the CMake target.
Build
The CMake target requires Qt Widgets and Qt WebEngineWidgets and builds only:
rktwebview_prg
Previous Qt update
QtWebEngine select popup rendering issues were observed with older Qt 6.x. The
native HTML <select> popup could keep growing or repainting while open while
the QtWebEngine process remained busy. Upgrading to Qt 6.11.1 resolved this.
Integration test
rktwebview_test starts the built rktwebview_prg with QProcess and tests
the stdio handshake, request/result matching, basic webview commands, and clean
shutdown. Run it from the build directory:
./rktwebview_test
For a protocol-only test that does not create a window:
./rktwebview_test --protocol-only
Set RKT_WEBVIEW_PRG to test a backend executable outside the test program's
directory.
