Roadmap for Nana 1.6

Cross-platform High-DPI Support

The most important new feature of Nana 1.6 is the cross-platform High-DPI support, which allows applications to automatically fit for High-DPI screen.

Some libraries provide automatic scaling to allow the applications written for standard resolution displays to be automatically scaled when shown on High-DPI screens. But Nana isn’t planned to provide the same feature, because the class place is naturally to support High-DPI. The aim of High-DPI support is to provide the density independent unit, like pt, in.

//something like this
button.typeface(paint::font({}, 18pt));

When the window moves from a standard resolution screen to a High-DPI screen, the size of the button’s font is always 18/72 inch(24px on standard resolution screen, 30px on a 120 DPI screen).

Listbox Virtual Model

Virtual model allows listbox to avoid loading all data into memory, it only loads the data where the listbox scrolls. It’s very useful when loads data from a big database table or a big file, it provides a significant efficiency and reduces the memory usage.
