![]() ![]() ![]() Remark: unfortunately, I do not have an opportunity to perform proper tests on other operating systems such as MacOS, that is why this part is more theoretical and only serves as an example of possible solution to the auto DPI scaling. Next we can set up a new virtual environment called cv with python 3.8.6. Then we install miniforge using Homebrew. Homebrew is a dependency manager for MacOS, and we will use it to install miniforge. Pros: total control of OSG / OpenGL content scaling which can be the only option when target OS provides automatic scaling (think retina display on MacOS).Ĭons: to resolve the multi-monitor awareness, have to perform the OSG/OpenGL content re-scaling whenever the application is dragged from one screen to another. The first step is to install Homebrew if you don’t have it. Update: since we now calcualte the scale using QApplication::desktop()->devicePixelRatio(), we will have only one scale value which will be applied the same manner for the resizing example above. It is possible to set it by: int main ( int argc, char ** argv ) Īfter we make sure we multiply every Qt dimension that we pass with the obtained scale, our application’s content finally runs correctly. ![]() Since the release of Qt5.6, high DPI support was introduced in Qt. Qt Development General and Desktop 4.8.4 Mac Install problems Congratulations to our 2022 Qt Champions 4.8.4 Mac Install problems jelemans, 22:54 Hello, I downloaded the Mac installer for 4.8.2 from today. This is certainly applicable if you want your Qt IDE to run on Windows, but when it comes to OS X you are very likely to run into the installer error clang installnametool failed.
