Re: button ICON

[Bob Sneidar via use-livecode]

As an added technique, if you have a single folder containing all your images, 
and your buttons already point to the image file for reference, you can "skin" 
your applications by simply swapping out the image folder with a different set 
of images with the same names, then reloading your stack.

Re: button ICON

[Phil Davis via use-livecode]

Hi Klaus,

The only method I can think of is where you set the icon of a button to 
the id of an image object, and then set the text of that image object to 
the binfile url of different image files. That does work, but may not be 
what you're looking for.

Re: button ICON

[Bob Sneidar via use-livecode]

I guess this goes way back to a long standing conversation as to the way 
buttons with graphics work in the first place. Let's say you have a group with 
several buttons. You now want to copy it to another project. Since the graphics 
are ALREADY OPEN in the project you copied from the button graphics *seem* to 
display fine. Until you quit livecode then open the target project by itself. 
No graphics! 

The fix is to go back to the original project, find all the graphics (probably 
hidden), copy those as well to the target app, edit the icons of the buttons to 
now point at the NEW ID's of the graphics, and hope you don't get it wrong. 

Someone showed me a trick. First group the graphics with the buttons they 
belong to. Then group all your individual button groups together. Finally put 
something like this in your top level group script:

on newBackground
   put the childcontrolNames of me into tGroupList
   
   repeat for each line tGroup in tGroupList
  put the childControlNames of group tGroup into tControlList
  filter tControlList with "btn*"
  
  repeat for each line tButtonName in tControlList
 put char 4 to -1 of tButtonName into tControlName
 put "img" & tControlName into tEnabledImage
 put "img" & tControlName into tDisabledImage
 if there is an image tEnabledImage then \
   set the icon of button tButtonName to the short id of image 
tEnabledImage
 if there is an image tDisabledImage then \
   set the disabledIcon of button tButtonName to the short id of 
image tDisabledImage
  end repeat
   end repeat
   pass newBackground
end newBackground

Re: button ICON

[Tom Glod via use-livecode]

Klaus, I vaguely remember someone recently pointing out a weird trick with
button icons ..

but i think it had to do with svgs being used as button icons.

but maybe it really was a dream.

why do u need to use images without loading them into the stack?

Re: Button Icon IDs

[Peter Haworth]

I had been playing around with other ways to do this until I got this
solution and came across what may be a bug.

After setting the icon of the button, I set the height and width of the
button to its formattedHeight and formattedWidth.  Sometimes that worked
correctly and sometimes it didn't.

I haven;t quite figured out what causes it to fail, but it seems like if
the height of the image is more than the height of the button, the button
height and width are set correctly, otherwise they aren't.

Re: Button Icon IDs

[Monte Goulding]

Use the resolve command. I implemented this to do exactly what you want: get 
the long id of the image that is used on an icon on a given button. You have to 
specify the button because that's what the icon is resolved relative to. It 
uses the same code the engine does to find the icon btw.

Cheers

If it's in the same stack, you should be able to:

  get the long name of control id x

But if it's in another stack then you need to reference the stack it's in:

  get the long name of control id x of stack y

Button Icon IDs

[Peter Haworth]

When setting the icon of a button, there is a hierarchy of locations that
LC uses to find the image.  However, if I subsequently try to reference the
image id in a script, LC won't find it unless I fully qualify where it is
(unless it's on the current card of course).

I want to set the height and width of the button to the height and width of
its icon image.  Is there any way to find the location of the icon image
from its ID?

That's great to know, thanks for trying it and reporting back. The SB is 
smarter than I thought.

I'm not sure how that would work, I always place the images so that the 
library isn't used at all. I suppose the easiest thing would be for the 
standalone builder to just include the whole library as a substack of 
your mainstack. Copying them individually would change the IDs of the 
images.


You could find out by building a small standalone with a button that 
uses a referenced icon, and whose script answers the names of the 
substacks. I'm a little curious myself what you'll find.

Just one more follow up to this.  When the standalone is built, does it

No, they'll show up fine if they are placed. If you use them as icons, 
be sure to use the placed image's ID. It's just a convenient way to keep

ID conflicts. Each stack can have its own ID numbering, so another 
control somewhere may have had the same ID. If the image with the 
conflicting ID is large or has transparent areas, it may have looked 
like the icon was empty.


Besides using a substack, you can also place all your icon images in a 
group on the mainstack and then unplace the group from all cards. 
They'll be accessible from anywhere, you won't need an extra stack, and 
no card will display them. ID conflicts can still occur, so each image 
will need a unique ID.




On a related topic, I'm wondering what are the advantages/disadvantages of
using the Image Library versus putting the application's images in a
substack.  I used to import my images into the Image Library and refer to
them directly in there but changed to using a substack because I got the
impression from some list posts that it might not be a good idea to use the
Image Library (can't remember why).


The image library is a convenient storage area for commonly used 
content, but it won't automatically move your images to your stack. That 
means if you distribute the stack or a standalone, the images will be 
missing. Use the library's "place" button to move the images into your 
working stack where they can be found.


It's no different than importing images from disk, but for things you 
use often the library is more convenient. I have a couple of image 
libaries I use all the time.

Re: Trouble with button icon images

[Bob Sneidar]

The only way I have gotten this to work reliably is to make sure that the 
images needed for buttons in a particular stack are IN that stack, not the 
mainstack, not a substack, but the stack that actually needs them. 

I suppose you could put them all in the mainStack, so long as the mainStack was 
not closed when the substack was running. Just hide the mainStack, don't close 
it.

Trouble with button icon images

[Pete]

I have a card in a substack of my mainstack that contains images for
buttons I use in other substacks.  All seems to work fine so far but I have
a problem with one button whose image does not show up.  The same image is
used as the  icon for buttons on other cards and shows up just fine.  If I
copy a button that uses the image from another card to this card, the image
disappears from the button.  Other buttons on the same card that refer to
different images work just fine.

Any ideas?

Re: Creating an auto-updating button icon thumbnail image from card snapshot

[Keith Clarke]

I tried 'import' first purely because I wanted to bring the snapshot of the 
unopened card into the 'home' card rather than export to file, etc.

There are some notes in the dictionary about setting the absolute rectangle 
coordinates depending on the target object - it didn't work until I defined the 
0.0.1024,768 parameters. I can't claim to have understood - I just fiddled 
around with all the options - process of elimination.

The good news is that my hack seems to have survived the test deployment out to 
a revlet. An online product demonstration presentation with (so far one) live 
thumbnail updates on the home page - not too shabby!

I'm getting to like this LiveCode thing and almost enjoying coding - it's all 
rather worrying! ;-)
Best,
Keith..

Okay, I made a new stack and getting a snapshot of a remote card works, 
even with "import". I tend to use the same test stack repeatedly for all 
kinds of junk until it gets too messy, and then I start a new one. Next 
time I'll make a new one right off.

Ah, that may be it. I almost never use "import", using "export" instead.

If one supports a feature the other doesn't, is it a bug?

I wonder if this is because export snapshot puts the stack in memory, along 
with the first card in the stack? Try it with the second card.

In fact, after reading your post I wondered if it was dependent on

Hi Jaque,
Thanks for responding. This is what I ended up with for updating a single 
button. I'm quite pleased with the result, because, as there are 'moving parts' 
on the visited cards, when I return to the home screen it is updated with 
thumbnails reflecting the current 'just left' view of the visited cards, rather 
than the default from when the presentation was first opened. 

on openCard
   --Delete the old thumbnail and set button to 'Updating'
   delete image "Snapshot-Example"
   set the showName of button "btn Example" to true
   set the label of button "btn Example" to "Updating Image"
   
   --get the new card snapshot and make it identifiable
   import snapshot from rectangle 0,0,1024,768 of card "Example"
   set the name of the last image to "Snapshot-Example"
   
   --scales the snapshot to thumbnail size
   set the height of the last image to 150
   set the width of the last image to 200
   
   --Make it the button's icon image and hide the updating message
   set the icon of button "btn Example" to the ID of the last image
   set the showName of button "btn Example" to false
   set the label of button "btn Example" to "Example"
   
   --Hide the imported snapshot
   set the layer of the last image to 1
end openCard

Once I have wrapped it in a loop for all the navigation buttons on the 'home' 
screen, I will publish a how-to document. This will be one of a few switching 
guides I have in mind for LiveCode newbies like me who were PowerPoint 'power 
user'. In my case, PowerPoint was my 'IDE for non-functioning wish-list-ware' 
for a couple of decades . 
Best,
Keith..

That's worth saving in my Livecode Keepers! Someday I am going to make a stack 
of this stuff!

I just tried the handler you posted and there's more wrong than just the 
icon ID.


on preOpenControl
   import snapshot from the rect of card "Example"
   set the icon of me to it
end preOpenControl

It might be a typo, but the first line will error without the "rect" 
keyword:  import snapshot from rect (the rect of cd "example"). Also, 
snapshots use the 0,0 point of the monitor (not the stack) for 
coordinates when dealing with cards, so the rect of a card will result 
in the snapshot containing the top left portion of whatever's on the 
monitor at that position. You'll need to translate the coordinates from 
global to local coords. You can either do that using the globalloc 
function or you can just use the rect of the stack instead of the rect 
of the card. The second method won't always work if you have a menubar 
on a Mac (which makes the stack shorter than the card.)


After either an import or an export, the "it" variable is not given a 
value, so it becomes the string literal "it". You can't set an icon to a 
string literal, you need an ID number.


While you can take snapshots of objects that aren't open, you can't take 
them of cards that aren't open. Cards are not objects. I was unable to 
get a snapshot of another card unless I went there first. This did work:


on test
  get the rect of this cd
  put globalloc(item 1 to 2 of it) into tRect
  put globalLoc(item 3 to 4 of it) into item 3 to 4 of tRect
  go cd 2
  import snapshot from rect tRect
  go back
  set the icon of me to the short id of last img of cd 2
end test

The "export snapshot" offers more options. You can export a snapshot to 
a variable and then put that variable into an image object. However, I 
was still unable to get a snapshot without going to the card. This works:


on test2
  lock screen
  go cd 2
  export snapshot from cd 2 to tVar as JPEG
  go back
  unlock screen
  create img "iconImg"
  set the text of img "iconImg" to tVar
  set the icon of me to the short id of img "iconImg"
end test2

It still won't work unless you use the ID of the snapshot image rather 
than what's inside the "it" variable.


Since you are taking snapshots of other cards and the "preopen" is for 
the control, I'm not sure you need to wait for the control to load. I 
think the issue is the ID of the icon.

Keith,

On preOpen... the control or card isn't open yet and you can't get a screenshot 
of it yet. A stacks or card needs to load completely before you can do such 
things. A very clear example is e.g. the impossibility to get the dimensions of 
a player if the movie of that player is being loaded duing a preOpenStack 
handler and the stack is invisible.

You might want to load a "please wait" picture first and load your custom image 
on openCard.

Creating an auto-updating button icon thumbnail image from card snapshot

[Keith Clarke]

Hi folks,
I'm working on a presentation stack, which has a home card with a set of 
buttons with thumbnail images (as the icon) that navigate to other cards in the 
stack. The other cards are evolving, so I'm trying to create an auto-update 
script to renew the navigation button thumbnail icon images when the home page 
is re-opened. I'm guessing that the script should end-up in a pre-open card 
script and iterate through a list of buttons, but I'm trying to get one button 
to work first.

Can anyone advise on what am I doing incorrectly with this script?

on preOpenControl
   import snapshot from the rect of card "Example"
   set the icon of me to it
end preOpenControl  

Best,
Keith..
