Cursor position changes not properly passed to input method

XMLWordPrintable

    • Android

      On Android, the platform input context does not implement update()
      (http://code.qt.io/cgit/qt/qtbase.git/tree/src/plugins/platforms/android/qandroidinputcontext.cpp?h=5.8.0#n645).
      Instead, it relies on connecting to the widget's cursorPositionChanged() signal
      (http://code.qt.io/cgit/qt/qtbase.git/tree/src/plugins/platforms/android/qandroidinputcontext.cpp?h=5.8.0#n684).

      As a result, custom widgets which properly interact with the input method via update() but do not provide cursorPositionChanged() suffer in the following way after changing the position:

      • The current word does not become the current preedit string.
      • The predictive text does not reflect the current context.
      • The next letter entered by the user is composed with the (invisible) preedit string from the previous context and inserted as the new preedit string at the cursor position.
