    Hi all,

    today wandering around the Android Developer site I met component TextSwitcher that made me think about a quick and easy way to set a few text effects to enrich any basic (very basic) app.
    So, here it is dgTextEffects!
    It can be used both from the Designer or from code.

    Basically it consists of a TextSwitcher able to quicly alternate between its two labels (which are inner elements) and a few preset effects to choose from.
    Using published methods it should be easy to set more effects.

    Keep in mind this was a very quick job (less than two hours from first reading about the TextSwitcher to this post), so everything is undoubtedly a bit inaccurate.
    Anyway it's usable enough to have some fun.

    Please find attached both the library and a demo app.

    Enjoy.

        TextEffect alternate setup - TE will be positioned and dimensioned as specified
        Base - panel container for TextEffect
        posX, posY - coordinates to position TE relative to its container
        awidth, aHeight - TE dimensions
      • setautostart (auto As Boolean) As String
        set if animation should automatically start on calling an effect
      • setcolor (BkgColor As Int) As String
        Set the TextEffects background color

      • setinterval (ms As Long) As String
        set animation interval in milliseconds
      • setvisible (Visible As Boolean) As String
        Set the visibility of the TextEffects object
