TextScreen

Discovered on the Wiki there is something called a roTextscreen, can someone post how to use it?
this doesn't work, and none of the links work on the wiki.
thanks

Edit - found the IfTextScreen page, still doesn't show when called from an info dialog button. (have all the colors set in theme)

Function Textscr()

texscr = CreateObject( "roTextScreen" )
texscr.setmessageport(m.port)
texscr.SetTitle("TITLE")
texscr.SetHeaderText("HEADER")
texscr.SetText("testtestetste")
texscr.show()


End Function

    As soon as your function exits, the local variable texscr will be destroyed, at which point the screen will disappear. So the screen will appear for only a split second, if at all. You need a message loop to maintain the screen after the Show.

    Ok got this working but the text is tiny. On third the size of any other text in the interface. It doesn't seem like Text:atttr can be used according to the docs, has this changed?

    thanks

    roTextScreen is meant for displaying large chunks of text like licenses and user agreements. I don't think you can change the size of the text. You might try a roParagraphScreen instead.

    The textAttrs attribute of the content-meta-data structure is used with roImageCanvas as described in Table 3 of the Component Reference (http://sdkdocs.roku.com/display/sdkdoc/ ... +Meta-Data).

    Thank you Chris, apoligies for ammending your quote. Smiley LOL

    Generalization isn't a good thing - much like stereotypes. The license agreements are in fact, read by lawyers - meaning someone reads them. 🙂
    I have used the roTextScreen to put up a user-accessible list of application changes since the prior revision. When there are a lot changes, it's nifty to be able to scroll down through the changelog rather than having multiple paragraph screens to contain all the information.
