  • Show groups of objects from single event

    Hi:

    I would like groups of text objects to show/hide from a single click on a hotspot.

    For example, I might have text objects named

    Text00_0
    Text00_1
    Text00_2

    Text01_0
    Text01_1

    etc

    ... and a %textGroup% variable set by a mouse click to 00, 01, etc.

    ... and then something like:

    Page.ShowObject=("Text + %region% + *")

    Can a string be made to concatenate "Text" + %textGroup% + wildcard characters and then used with a single SHOW action?

    Thanks,

    Nope. The actions don't support wildcards for the object names at all.

    But, you can definitely concatenate text with an expression (using a "Variable - Set Value" action), or even just mix-n-match the variable with the text to form the value you want.

    If you only have a few objects, it'll probably be easier to just use separate Show and Hide actions for them.

    If you have a lot of objects, though, you could try using a While loop, like this one that would hide 10 objects:

    <pre>%i% = 10
    WHILE (%i%)
    Page.ShowObject=("Text%region%%i%")
    %i% = Evaluate(%i% - 1)
    END WHILE</pre>

      In fact, here's an example that will show you how it works. [img]/ubbthreads/images/icons/smile.gif[/img]

        Lorne:

        Thanks very much for the WHILE loop example; it tells me everything I need to know for this page!

          You're welcome Phillip. [img]/ubbthreads/images/icons/smile.gif[/img] I was curious to see if it would work. [img]/ubbthreads/images/icons/wink.gif[/img]

            ... From the should work but doesn't department :-)

            OK, I can't see why this (see attached) does not work.

            The WHILE loop that hides the objects is never executed, but I cannot see while the condition is not met. Is there some other factor getting in the way here?

            Hope I have attached this list correctly ...

              You aren't initializing %i% to anything before the WHILE loop. The %i% variable will be seen as that exact text (%i%) and so the >= operator in the expression:

              %i% >= 0

              ...will perform a string comparison between the word "%i%" and the word "0".

              % comes before 0 in the ASCII table, so that test ends up being false right from the get-go.

              That's probably your answer...unless you're initializing %i% some integer larger than -1 somewhere else (i.e. in another action list that happens before this one).

                Here is the complete action list -- I hope.

                I believe that before the WHILE test runs, %i% will have been set:

                %i% = "1" (or "2", etc, depending which hotspot was clicked)

                Do I need to do that differently to make it an integer rather than a word?

                Anyway, while testing I put a text box on the page and set it to display %i% -- and it looked like a 1 was there before the WHILE condition is tested :-)

                Is the Equal operator not the correct one to test if %i% has the value 1?

                  I have found my error - the value of i was set -- but then un-set again -- by a previous WHILE loop. I must remember to keep refreshing the values of those test text objects. Oops.

                  Thanks for your help!

                    Nope. There's actually no difference...AutoPlay figures out what you meant by the context. For example:

                    1 + 1

                    both values are numbers, so an addition is performed: 2

                    1 + tree

                    one of the values is obviously a string, so concatenation is performed: 1tree

                    1.2.4 + 1.0.1

                    the values both have more than 2 decimal points, so a "version addition" is performed: 2.2.5
