What is your "objection" to the forum?

I find it better than the Use-List as one can attach stuff.

Re: screenRect and screenLoc weirdness

[Monte Goulding via use-livecode]

Hi Marty

I’m just wondering if you are using the standard IDE ask and answer dialog or a 
custom one? If you are working on a very old stack then MetaCard used to copy 
the ask and answer dialog into the stackFile as a substack. You should be able 
to see them in the project browser under your mainstack. If that’s the case 
then perhaps try deleting those.

Cheers

Monte

Does that work for you Paul - it doesn’t for me. I’m having to do this:

send CenterAnswerOnScreen to me in 1 tick
answer “Blah blah blah”

on CenterAnswerOnScreen
   set the loc of stack "answer dialog" to the screenLoc
end CenterAnswerOnScreen

I have a couple of customers with small-screened laptops who use large 
secondary monitors aligned at the bottom. Thus the top of the secondary monitor 
is quite a bit above the main laptop monitor. Ask and Answer dialogs are so far 
off you can only see about the bottom 1/8 of an inch of the window and are thus 
unusable.

See https://quality.livecode.com/show_bug.cgi?id=4309

A very old enhancement request that would be a nice addition. SuperCard 
has a 'at' syntax, so you could say:


Ask "What color is your favorite?" at screenLoc()

Now you have to do something like

set the loc of stack "Ask Dialog" to screenLoc()
ask "What color is you favorite?"

The actual stack names are "Ask Dialog" and "Answer Dialog" whether 
invoked from the IDE or a Standalone.

Re: screensChanged ? (was Re: screenRect and screenLoc weirdness)

Aha! Thanks Paul, that's just what I needed. I looked through all the 
'changed' messages in the dictionary but didn't spot that one.

Re: Repeat for each line of a variable or field?

[Bob Sneidar via use-livecode]

Also if you do not lock the screen the engine has to update the display each 
time a line changes. Not sure if this is the case if the line is not visible...
