Moving page up and down

[jalz]

Hey Guys,

Need some advice, just can't get my head around this one. I'm building a print layout and I have sized it so I have a header and footer printing roughly around my printer. The problem is the depth of my screen is fairly shallow and I would like to scroll up and down my card to make sure its ok before I send it to print.

The obvious way to do this would be to use the scrollbar control. What I don't understand is when I drag the scrollbar across from the palette of controls, how do I then associate the scrollbar to move the content up and down my card.

I was looking into grouping objects and then applying a scrollbar, but as my scripts are building these print cards from scratch, grouping objects seems quite cumbersome, Id rather copy a preformmatted scrollbar control to my page. Does anyone have any ideas how I can implement the scrollbar to my page and get it to display header, body and footer information. A tutorial or sample stack would her perfect. I'll upload a screenshot to show you what I have, you can't see the footer as it goes beyond my screen.

Thanks as always

Jalz

Hi Jalz,
I just spent 5 minutes trying to select and group multiple controls and it's not all that difficult.
1) put the long id of the control into a variable
2) set the "selected" of each control to true -- you will have to remove the controls that you don't want in the group e.g. Print button
3) group
4)set the vScrollbar, set the rect, set the lockLocation

Now I guess that's kind of pigheaded of me to say "just" but I'm pretty sure you know most of what I said.
Grouping is probably the fastest way to get what you'd like.

hmmm... how would lockLocation affect a print job, you may have to unlock and formattedHeight, topLeft at print time.

...cumbersome

Not really even with on-the-fly page building
repeat with x = 1 to the number of controls

Do you want to see the full card only in development (to make sure it's right) or do you want users to also be able to view it? If it is just for you, you don't need to do any scrolling. Just set the top of the stack in the message box:

Code: Select all

set the top of this stack to -200

Change the number to whatever works. When you're done looking, set the top back to a positive number. Richard Gaskin has a little UI tool that lets you move stacks around without the message box but I don't have a link. Maybe he'll chime in here. I think there are some others that do the same thing too.

LC will truncate the bottom of the window if there isn't enough room to display it all, so just moving the top of the stack may not be enough. You'll need to set the height of the stack to its normal height first, before repositioning the top.

An alternative, which would work for users as well as you, is to play with the scaleFactor property (only available in LC 6.6+):

Code: Select all

 set the scaleFactor of this stack to 0.5

This will scale the stack to half size so you can see it all. You can change the percentage to whatever looks best.

Hi both,

Thanks for replying. I've implemented the scale factor to see how it works and its not what I am looking for to be honest.

So Im going to bite the bullet and try and get scrollbars to work on my page. I've looked at Simons steps, yes most of them I think I can learn, find out how to do if I don't know them already. However grouping all the items on my layout I'm having trouble with.

I've got some code below. What I am trying to do is create a group called myprintdata and then loop through each object on my layout and add it to that group. The card contains a number of different types of objects, including groups, controls and fields. Using the dictionary I came across selectedObject which seems the right keyword to use for all objects. I couldn't get it work I've tried to use the it keyword as I figured that whilst looping I would be on the object, but again failed to loop through.

Code: Select all

   create group myprintdata
   repeat with x = 1 to the number of controls
      --if the short name of the selectedObject <> "print_bar" then group
      --put the short name of the control into tName
      --answer tName
      add it to group myprintdata
   end repeat

Thanks as always

Good stuff!
in your loop use this

Code: Select all

set the selected of the long id of control x to true

Don't forget you'll probably group some controls that you might not want in the scrolling group

Code: Select all

if the short name of control x is "Print" then next repeat.

Hi Simon,

Thankyou for your assistance. Your code works awesome, it selects the objects on my layout. The only thing I can’t seem to do is finally group the items selected on my layout, it seems to error at that stage. I would have thought and looking at other examples online, group is the keyword I should be using to group the selected items but I'm obviously doing something wrong.

Code: Select all

on mouseUp
   repeat with x = 1 to the number of controls
     if the short name of control x is "print_bar" then next repeat
      set the selected of the long id of control x to true
   end repeat

   --group –I would have thought this line would have grouped the items. Perhaps I need to put them into a group list?
   --if the number of lines of the selectedObject > 1 then group
   -- rename the group to "myPrintGroup"
   -- set the topleft of group "myPrint"
   -- set the height of the group "myPrintGroup" to 400
   set the vScrollbar of group "gg" to true
end mouseUp

Thanks

Right, "group" is what you want and I''m not sure why it doesn't work. It should. But you can try passing the object list rather than selecting each control.

Code: Select all

repeat with x = 1 to the number of controls
     if the short name of control x is "print_bar" then next repeat
    put the long id of control x && "and" & space after tList
end repeat
group tList

Hi both,

I'm still encountering errors whilst performing the group. Do

Simons method - "group" I get the following error:
execution error at line 8 (controls don't have the same owner), char 1
-line 8 is the line the contains group

Jacques, method produces the following error
execution error at line 7 (Chunk: error in object expression) near "graphic id 5059 of group id 5058 of card if 5057.."

Thanks

Hi jalz,
Ahhh... It's trying to group the individual controls that have already been grouped.
Using the long id can you figure out when it's a control already inside a group and do a next repeat? Only select the group not the controls inside.

Would this (shuffleAbout) be of any help ?
