New Features in Qt 5.15

Note that this list should be considered as work in progress until the first Beta release.

New Features (within existing modules)

• Qt 3D
• Qt Bluetooth
• Qt Core
• Qt GUI
• Qt Location
• Qt Multimedia
• Qt Multimedia Widgets
• Qt Network
• Qt QML
  • Added qmlformat tool which automatically formats any QML file according to the QML Coding Conventions.
  • Added support for the Nullish Coalescing Operator (??)
• Qt Quick
  • Added a PathText type, which can be used together with Qt Quick Shapes to render text as geometry and not based on distance fields or pre-rendered textures. This can be useful for rendering large font sizes which would otherwise consume a lot of texture memory.
  • Added Image.sourceClipRect to specify a clipping region, to request the image plugin to render a portion of an image source.
  • Added cursorShape property to pointer handlers. Most pointer handlers (e.g. DragHandler) will change the cursor when the active state is true. HoverHandler will change it when the mouse is hovering over the Item that contains the HoverHandler.
• Qt Quick Controls 2
• Qt SerialBus
• Qt Test
• Qt Wayland Compositor
• Qt WebEngine
• Qt WebSockets
• Qt Widgets
• QDoc
  • QDoc can now generate DocBook.
  • QDoc now generates output for C++ class and function template parameters.
  • QDoc now generates correct output for scoped enums (enum classes).
