Virtual Keyboard problem on raspberry pi 3

  • Hi
    I'm trying to run virtualkeyboard example on raspberry pi 3 with qt cross compile.
    i can compile the example without any error.
    when I'm running the example, it deploy without any error:
    Unable to query physical screen size, defaulting to 100 dpi.
    To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).
    and application appear on my touchscreen display. but problem is that when i touch any text field , keyboard doesn't appear and i cant enter any text.
    i appriciate it if everyone solved this problem before give me an idea to fix it.
