Re: Down a leafy lane or up queer street?

[Bob Sneidar via use-livecode]

I avoid global variables as these are visible to any open stack you are working 
on, so you cannot have 2 stacks open that use the same global names or they 
will overwrite each other. Instead I use the custom properties of the mainstack 
as an ad hoc stack global system. I do this with cards and objects too. It 
means I need to have a line in each script for each property I want to use, but 
an easy fix for that is to have a handler in the object script that sets the 
values of script local variables to the values of the custom properties you 
need. You only have to run this once, say on openCard. Now you have script 
local variables set to the values of all your properties, AND they have the 
added virtue of being persistent through app launches.

Re: Down a leafy lane or up queer street?

[Tore Nilsen via use-livecode]

The variabel scope can be a bit tricky. The difference between a script local 
variabel (declared as a local variabel outside any handlers) and a global 
variabel can be confusing. They act very much the same way when used within one 
script. The main difference being that a global variabel can be used in any 
script when it is declared in the same script. Both variabels retain their 
values between handlers and sessions as long as the application is open. To add 
to the confusion, temporary variabels (undeclared or declared local within a 
handler) are referred to as local variabels also.

For the convenience of my students I refer to variabels that are undeclared (or 
declared within a handler) for temporary variabels, with names starting with 
t-. I only refer to local variabels as local when they are declared outside of 
handler, and I use names starting with s-. To make sure that global variabels 
are easily recognised as such I start their name with g-. I use the same naming 
convention for arrays. I also declare all global and script local variabels at 
the top of my scripts. Then I am sure they will be available to all handlers in 
that script.

I imagine that if you had strict mode enabled then the IDE would flag it
for you too (if undeclared).

Re: Down a leafy lane or up queer street?

[Mike Bonner via use-livecode]

Did you declare it as a global on the card also?  You have to declare it
for every context that it will be used.  Stack, card, if you use it in a
button script, wherever.

If you've declared it in a card script, and set its value, but then use it
WITHOUT declaration all you get back is the text of the name (IE route66)

The reason you can see the value when checking it from the message box, is
that it is executing the commands as if they were in the context of the
stack script.

To test what I mean, create a script in a button with the following:

on mouseup

put "undeclared variable:" && tUndeclared -- shows tUndeclared in the
message box

local tDeclared

put cr & "Declared but un-set variable:" && tDeclared after msg -- no value
shown, tDeclared exists but is empty

put "value set" into tDeclared

put cr & "Declared and value set to: " & tDeclared after msg -- tdeclared
exists and now has a value

end mouseup

Re: Down a leafy lane or up queer street?

[Tore Nilsen via use-livecode]

If route66 is declared as a local variabel in the card script (and it must be 
declared outside any handlers), then all other scripts that uses this variabel 
must reside in the card script as well. If it is declared as a global variabel, 
it must be declared in all scripts that uses this variabel.

RE: Down a leafy lane or up queer street?

[Ralph DiMola via use-livecode]

Richmond,

First of all I never use lockscreens in preopencards. It's redundant unless
there are some conditions I'm unaware of.

I recently had this problem when I used "file==>Import control from==>image
file" and then subsequently set the filename property. It seemed like once
the image control was using an image imported to stack I could never set the
filename property and get anything other than the "horrible gray square". I
don't think it was always this way. What I did to fix it was to delete the
control and then added an empty image control from the IDE tools pallet.
After that I was able to set the filename property and see the images just
fine and dandy. Any chance this is also your problem?

Try this:

local sFolderPath

on preOpenStack

put specialFolderPath("resources")&"/myCrap/rez/" into sFolderPath

end preOpenStack


specialFolderPath(“resources”) will point to the folder containing the stack 
when you are in the IDE, and to the resources folder of your compiled 
application

Re: Down a leafy lane or up queer street?

[Richmond Mathewson via use-livecode]

Here I go agin, replying to my own posting:

I have this script in the stack:

onpreOpenStack

setitemDelto"/"

setthedefaultFoldertoitem 1 to-2 of(theeffectivefileNameofthis stack)

endpreOpenStack

but it ain't working.

So, there I am opening an on-going project I have been "somewhat 
remiss" about of late

what with one thing and another.

Now this project has a ton of images made via the Object/New 
Control/Image menu
and for their image data in their property panels are referred to a 
folder called "rez"

that resides in the same folder as my stack.

Now when I set up the stack the source field in the property panels 
went something

like this:

/Users/richmondmathewson/Desktop/myCrap/rez/c7.png

and "everything worked perfectly" . . .

on reopening the stack the image data does not show up
and the source fields contain this sort of thing:

rez/c7.png

now this "just won't do" as the . . . well, never mind; probably that 
is too filthy a joke for the Use-List.


So . . . presumably, I need a sort of 'set the default file path' 
script in my openScript thang?

Down a leafy lane or up queer street?

[Richmond Mathewson via use-livecode]

Probably both . . .

So, there I am opening an on-going project I have been "somewhat remiss" 
about of late

what with one thing and another.

Now this project has a ton of images made via the Object/New 
Control/Image menu
and for their image data in their property panels are referred to a 
folder called "rez"

that resides in the same folder as my stack.

Now when I set up the stack the source field in the property panels went 
something

like this:

/Users/richmondmathewson/Desktop/myCrap/rez/c7.png

and "everything worked perfectly" . . .

on reopening the stack the image data does not show up
and the source fields contain this sort of thing:

rez/c7.png

now this "just won't do" as the . . . well, never mind; probably that is 
too filthy a joke for the Use-List.


So . . . presumably, I need a sort of 'set the default file path' script 
in my openScript thang?
