ScreenZoom is a small Qt application that illustrates how to grab screen areas under a cursor and display them zoomed.
This illustrates how to grab screen areas under a cursor, no matter which display your cursor may be on in a multi-monitor configuration. This was tested with Qt 5.15.2, however it should work with Qt 5.10 or above, or Qt 6.
You can build one of two ways:
- Right in Qt Creator by loading the qmake .pro file
- From a command shell by invoking qmake and make.
