    Scrollbar in XNA

    Reply Quote
    I'm making my own component library at the moment, but I'm having trouble making a scrollbar for my textarea.

    Is it possible to mask a part of the textarea (sprite), so I can give my mask different y coordinates depending on what part my scrollbar is.

    Thanks!

    Why is your textarea a sprite? Shouldn't it be text, in which case you would simply select which lines of text to render at what location? (To answer the question asked: look at the sourceRectangle parameter to SpriteBatch.Draw)

    You need to render (draw) the text, right? You can't just put up real text, correct me if I'm wrong though.

    Well is your text precreated in a 2D editor such as Paint and loaded as a Texture2D? If so that's usually the wrong way to do it for general text - load a SpriteFont and use SpriteBatch.DrawString.

    As for scrollbars, check out the link in my sig for the ScrollbarComponent. It might do what you want.

    My textarea IS a sprite, though my text is not. My text is, just like you said a spritefont;).
