Here's a niggly little thing.

So I have an editable text sprite that users put their name in but the I-beam
is at the end and I'd like to hilite the text "Name" so that when they type it
immediately clears it. I've used the code line

sprite("myUserInput").member.selection = [0, 4]

and it works...for a very short time. The selection doesn't stick. If I use on
prepareFrame it is always selected but I can't put any more text in (except one
character). If I use beginSprite it doesn't take. I've tried putting it in a
frame script, in a sprite script, in a cast member. I'm know this is simple but
I'm going round in circles

Thanks

To take a different approach, you could simply set it up to clear itself
the 1st time someone starts typing in it, obviating the need for the
whole selection thing.


property pBeenUsed

on beginSprite me
pBeenUsed=0
sprite(me.spriteNum).member.text="Name"
end

on keyDown me
if pBeenUsed=0 then
pBeenUsed=1
sprite(me.spriteNum).member.text=""
end if
pass
end

I changed the member to a field member and it worked well enough. I still couldn't get it to select just the word rather than the whole field and it should have worked with the text member. Harrumph!

I'm not sure exactly the effect you're looking for, but this may help give you
some more ideas:
-- behavior script attached to the text sprite
property spriteNum, mem

on beginSprite me
mem = sprite(spriteNum).member
end

on enterFrame me
if the keyboardFocusSprite <> spriteNum then
the keyboardFocusSprite = spriteNum
mem.selection = [0, mem.char.count]
end if
end

That's not the way that selection was intended to be used. Selection when used
with a text or field member, is a function. When it is used with a castLib it
is a property.

If you want to get a particular string in a text or field member, then you
might want to use something like this:

property thisSprite
property thisMember

on beginSprite me
thisSprite = me.spriteNum
thisMember = sprite(thisSprite).member
selStart = 1
selEnd = 4
put chars(member(thisMember).text,selStart,selEnd)
end
