SOLVED! Thanks Keith.
I should have noticed your post before I replied… Yay! This works!
Thank you so much. It is perfect!
For testing (and FYI to anyone else who wants to know):
Created a FORM: named pdf_Viewer. Form.pdfURL [to store the path as
per file:/// …]
Added:
• web area: named web_pdfViewer
• variable: named dropZone expression type OBJECT with ‘droppable’
attribute; ‘on drag over’ and ‘on drop’ as only events
Then this code in the dropZone script:
C_LONGINT($0)
Case of
: (Form event code=On Drag Over)
// Accept On Drop event only if the pasteboard contains
files, reject otherwise.
If (Get file from pasteboard(1)="") //no file in pasteboard
$0:=-1 //reject drop
End if
: (Form event code=On Drop) //Requires Droppable action enabled from
Property List
$dropName:=Get file from pasteboard(1)
If (Test path name($dropName)=Is a document) // if it is a
document...
$droppedFile:=File(Convert path system to
POSIX($dropName)) // get the FILE
If ($droppedFile.isFile) // is a file!
Form.pdfURL:="file:///"+$droppedFile.path
WA OPEN URL(*;"web_pdfViewer";Form.pdfURL)
End if
End if
End case
And it displays the PDF in the webArea with ability to scroll through the whole
document.
I have never used web areas in 4D so I will need to explore the benefits of it.
I notice it can also be used to display .png files and others dragged into that
‘dropZone’ variable object on my form.
