* Examples: fix touch handling in painting examplesVolker Hilsheimer2023-12-151-3/+6
| | | | | | | | | | | | | | | | | | | | On macOS, we don't deliver a press event for the first press on the track pad (Qt::WA_TouchPadAcceptSingleTouchEvents is not set by default, so Qt doesn't deliver a single-press on the track pad as a touch event - that makes some sense or at least maintains compatibility). Because of that, point 0 is never added to the finger-mapping hash. When point 0 is then released, we didn't check if we found a valid iterator for that point ID, and the example crashed. Fix this by checking that we have a valid iterator before dereferencing, and by handling Stationary events in the same way as pressed (add the point to the mapping if it's not already there). Pick-to: 6.7 6.6 6.5 Fixes: QTBUG-110266 Change-Id: I32337b801aaabf9b821a97ddc15ad78747b5e6a2 Reviewed-by: Jan Arve Sæther <[email protected]>
* Examples: remove OpenGL code paths from painting examplesVolker Hilsheimer2023-10-271-14/+0
| | | | | | | | | | | | | | | | The extra code for using the OpenGL paint engine is significant enough to be distracting from what the examples are supposed to show. If we want to show how to use QPainter on an OpenGL widget, then we can make dedicated and documented examples for that, in the OpenGL category. And we have such examples in the Qt OpenGL module anyway. As is, the examples feel more like manual tests of the OpenGL paint engine; if we need more coverage there, then we can add it there.

* Port from qAsConst() to std::as_const()Marc Mutz2022-10-111-1/+1
| | | | | | | | | | | | | | | | We've been requiring C++17 since Qt 6.0, and our qAsConst use finally starts to bother us (QTBUG-99313), so time to port away from it now. Since qAsConst has exactly the same semantics as std::as_const (down to rvalue treatment, constexpr'ness and noexcept'ness), there's really nothing more to it than a global search-and-replace, with manual unstaging of the actual definition and documentation in dist/, src/corelib/doc/ and src/corelib/global/.

| | | | | | | | | | Users should use range constructors instead to do the conversion. Keep conversion methods between QList and QVector as these will turn into a no-op in Qt 6, whereas forcing people to use range constructors would lead to deep copies of the data.
