  • How to make a full-screen application by 4DPi-24-HAT.

    Hi all,
    My 4DPi-24-HAT works well as a Primary Display of Raspberry Pi.

    Now, I want to use it as a full screen touch-panel.
    The menu-bar of Raspbian OS is unnecessary.
    And the frame is unnecessary.
    I want to make a simple full screen application with touch.
    The programming language is "C++".

    Please show me the point of technique.

    Or, can I develop an application by "Workshop4" ?

    Thanks,

    Hi,
    Thank you for seeing this contribution.

    I found one method of solving this.

    We can solve it by using the library of Qt.
    I made the program of the image data processing by using OpenCV.
    The highgui module of OpenCV was able to be enhanced with Qt.
    And, the property of window can change to the full-screen mode.

    example code
    setWindowProperty( "MyWindpw", CV_WND_PROP_FULLSCREEN, CV_WINDOW_FULLSCREEN );
    Just only this!

    Information of of setWindowProperty() of OpenCV is here.

    Can anyone show another methods?

    Thanks,
