Rolling texts in Oracle forms

Dear fnds,

In HTML, we have something called "marquee" that will roll the text in the desired direction (i.e., left to right, top to bottom etc..) in the screen or in the specified frame.  Is this possible in D2k.  If so, how?

Thanks

Yes, it is possible. In the text item property list change an property which name is something like "Multirow" and look also for scrolbar property in that item. Set it to "yes".

Forms has an excellent online help. Use it! search for "Multirow text items" or something like this. The same for Oracle Report.

I have not come across a Marquee option or similar in Forms or Reports.  However, in Forms you could utilise TIMERS to either move or adjust the value of an item to mimic a marquee.

Oracle Forms Demos contain a GUI demo with Spinning Wheels and a Status Bar using a techniques that you could apply.  The spinning wheel example uses a timer to move the canvas viewport over several different images.

For a small amount of text, I would suggest, using a display item which you can display your text in.  Each time the TIMER expires run code to adjust the text viewed in the field E.G.

First Expiry       "THIS IS MY MARQUEE"
Second Expiry   " THIS IS MY MARQUE"
Third Expiry      "  THIS IS MY MARQU"
Second Expiry   "E  THIS IS MY MARQ"
Second Expiry   "EE   THIS IS MY MAR"

For larger or more complex pieces of text consider using a canvas with the text and have the expiry of a timer move the canvas viewport a few pixels each time.  When this canvas is stacked on to your content canvas the text will appear to flow.

Thanks.  I will try your suggestion.  Other than "Timers",  Do we have any other option in D2k to get the functionality of a marquee.
