Re: fullscreenmode and rect of a substack on mobile device ?

First, I think you have a typo where "/25" should be "-25"...
  set loc group "footer" to ( (item 2 of tRect)/2,(item 4 of tRect)/25 ) #
Typo: -25

Second, for safety, ensure integer values...
 set loc group "footer" to round((item 2 of tRect)/2), (item 4 of tRect)-25 

Third, if still not working on preOpenstack, try...

on preopenstack
  if isMobile() then
mobileSetAllowedOrientations "portrait,portrait upside down,landscape
left,landscape right"
  end if
  hide this stack
end preopenstack

Re: fullscreenmode and rect of a substack on mobile device ?

[FlexibleLearning.com via use-livecode]

Coming in late to the thread, but would this not work on all platforms?

on preOpenStack
  setupStackRect
end preOpenStack

on orientationChanged
  --  setupStackRect
end orientationChanged

on setupStackRect pWidth,pHeight
  if pWidth="" and pHeight="" then
put the effective working screenRect into tRect
set the rect of this stack to tRect
set the topLeft of this stack to item 1 to 2 of tRect
  else
put the rect of this stack into tRect
put tWidth into item 3 of tRect
put tHeight into item 4 of tRect
set the rect of this stack to tRect
  end if
end setupStackRect

You would obviously need to handle individual control geometry as needed,
but I found using a (hidden) master group of template graphics to define
regions a straightforward way to implement consistent geometry settings...

Set [the geometry] of [object] to [the geometry] of [graphic]
e.g. set the topleft of fld "About" to the topLeft of grc "template_Body"

Cancel all that... my object referencing error by omitting "of me". Must be

Except now the dataGrid no longer scrolls... Restart the engine... Now it

DataGrid image display woes

[FlexibleLearning.com via use-livecode]

Okay, I have a datagrid Form with a template to display an image and 4
fields. 

The fields display the correct data for each line/record, but the unique
image for each line/record is not being correctly displayed.

If the dataGrid height can show all records, the image for the last record
is displayed in the first line and all the other images are empty. If the
dataGrid requires scrolling to display all the records, only every 7th line
displays an image and the image changes as the group is scrolled. I have
tried all the versions I have from from 5.54 up to 8.1 with the same
problem.

Is this a known issue?

RE: modal window = block handler?

[FlexibleLearning.com via use-livecode]

If “popup” is non-blocking then it’s a bug. However, I hope that the 
non-blocking behaviour of “open invis as modal” is retained, or there is no way 
to indicate progress in a modal.

Friends,

 

Just to add a related note here, at least on 9dp5 the "popup" command is also 
not pausing. It is supposed to pause the handler that calls it until menupick 
happens but in my experience here it simple keeps running even while the modal 
is open.

 

This might be related.

Re: modal window = block handler?

[FlexibleLearning.com via use-livecode]

If you open invisible, then display it, a modal will not block. This
non-modal behaviour of a modal has been incredibly useful for displaying a
progress  indicator in a modal window. I do not consider it a bug as such
(modal blocks underlying windows, not necessarily code), and would hope this
quirk remains available. Otherwise we would need something like "go stack as
modal with messages".

URGENT: Mixed orientation printing to PDF

[FlexibleLearning.com via use-livecode]

I have a 5.02 legacy stack that prints A4 pages to PDF using "open printing
to pdf".

The documentation says that the printPaperSize must be set before calling
open printing, suggesting that changes to the printPaperSize after "open
printing" are not supported (I tried, and it seems so).

I can successfully set the printPaperSize to 595,842 for Portrait or 842,595
for Landscape. printPaperOrientation seems redundant and also cannot be
changed after initialisation.

So is it possible to print mixed portrait and landscape pages in the same
PDF?

Help! I only get digests, so please email me direct!
