问题
I'm using virtualkeyboard of Qt5 on embedded device, and no mouse, the keyboard is not full pc keyboard, but just has eleven keys, which include up/down/left/right, enter, esc....
so I want focus on virtualkeyboard, and use up/down/left/right/enter to control virtualkeyboard, simulate mouse to click on virtual key.
how to do?
回答1:
There doc.qt.io/qt-5/qtvirtualkeyboard-build.html mentioned that qtvirtualkeyboard should be build with arrow-key-navigation option. Like this
qmake /path/to/qtvirtualkeyboard.pro CONFIG+=arrow-key-navigation
Also recommend to build examples/virtualkeyboard/basic/ with disable-desktop option and use it sources as example.
