* remove unused variables and parameters to fix compilation with g++-10.2Andreas Buhr2020-11-131-2/+2
| | | | | | | | | | | The changes in 94dd2cebdcb9446626cd32a00086431eb11ab2a4, "Remove Qt4Compatible painting" left some unused variables and parameters. This leads to warnings which are treted as errors and thus inhibit a successful build with g++-10.2. This patch removes them and thus enables building with g++-10.2 again.

* Clear old triangulated vertex data when a path is completely clippedJoni Poikelin2020-08-051-1/+1
| | | | | | | | | | | Old data was held in buffers which caused OpenGL paint engine to re-render previous shape again with current settings if the current path was completely clipped.

* Fix artifacts when rendering multisubpath dashed QPainterPath with openGLDmitry Kazakov2020-05-151-8/+27
| | | | | | | | | | | | | | | | | It might happen that the resulting subpath generated by the QDashStroker will have no lines at all. It happens when further LineToElement items compare as equal to the starting MoveToElement when compared in 'float' space. In such case QTriangulatingStroker::process() skips LineTo elements and the vertexBuffer ends up with unconnected vertices, which generate unwanted triangles.

| | | | | | | | | | | Move away from using 0 as pointer literal. Done using clang-tidy. This is not complete as run-clang-tidy can't handle all of qtbase in one go.

* Silence maybe_uninitialized warning with gcc -OgAllan Sandfeld Jensen2016-12-211-1/+1
| | | | | | | | | | GCC produces false positives for maybe_uninitialized when compiling with -Og in these three places. Simply initialize the variables to silence it. This should be entirely cost-free for normal compilation.

* Move QTriangulator and QTriangulatingStroker classes to paintingAndy Nichols2016-08-151-0/+613
Previously the private APIs for QTriangulator and QTriangulatingStroker were located in src/gui/opengl because they were used by the OpenGL paint engine. These API's are not actually specific to OpenGL however, and were not being built when QT_NO_OPENGL was defined. It makes more sense for these classes to belong in the painting subgroup. Aside from the OpenGL paint engine, these private APIs are used by QtLocation to triangulate polylines to be rendered by QtQuick.
