Removed C++ functions
All functions that were deprecated in the previous version of Qt for MCUs, are removed in v2.0. The following table lists these functions and their alternatives.
| Removed | Alternative |
|---|---|
| uchar *DrawingDevice::pixelAt(int32_t x, int32_t y) const | Qul::PlatformInterface::PixelDataPointer DrawingDevice::pixelDataAt(int32_t x, int32_t y) |
| uchar *DrawingDevice::pixelAt(Qul::PlatformInterface::Point pos) const | Qul::PlatformInterface::PixelDataPointer DrawingDevice::pixelDataAt(Qul::PlatformInterface::Point pos) const |
| Qul::PlatformInterface::Texture::dataAtOffset() | Qul::PlatformInterface::PixelDataPointer Texture::pixelData(int16_t x, int16_t y) const |
| int32_t Qul::PlatformInterface::DrawingDevice::bytesPerPixel() const | int32_t Qul::PlatformInterface::DrawingDevice::bitsPerPixel() const |
| int8_t Qul::PlatformInterface::Texture::bytesPerPixel() const | int8_t Qul::PlatformInterface::Texture::bitsPerPixel() const |
| int Qul::Image::bytesPerPixel() const | int Qul::Image::bitsPerPixel() const |
| Qul::Application::setUiLanguage() | Qul::ApplicationSettings The following example shows how the application's UI langauge can be set in Qt for MCUs 2.0 compared to 1.9. Qt for MCUs v1.9 and earlierQt for MCUs v2.0 and later |
Modified C++ APIs
Qul::Platform namespace
Since Qt for MCUs 2.0, functions that were previously defined in the Qul::Platform namespace, are moved to the new PlatformContext structure. The platform implementations inherit this new structure and override its virtual functions. Qt Quick Ultralite core accesses these platform-specific functions using the Qul::Platform::getPlatformInstance() function. For more information see PlatformContext and Qt Quick Ultralite Platform Porting Guide.
Here is an example of PlatformContext usage compared to Qt for MCUs 1.9:
