Re: With v18r2, can 4D display pdf documents?
4D v18 is 750 MB. just over half of that size is taken by the embedded CEF web area. So it would be a shame not to use it at all other than for the welcome dialog. my understanding is that the Chrome Embedded Framework is using the same PDF renderer as Chrome, that is, PDFium, a Google edition of the Foxit render. https://opensource.google/projects/pdfium https://www.foxitsoftware.com/blog/foxit-pdf-technology-chosen-for-google-open-source/ note that you can pass a posix path or a system path or an URL to the Web area. the difference between posix or system can be determined by the delimiter. but the difference between a path or an URL is less obvious, especially if you pass a file name. the reason you need to append the "file://" protocol, and to use an absolute path that begins with a forward slash (which results in a triple slash), is that as silly as it sounds, "test.pdf" by itself could be interpreted as an internet domain name and therefore ambiguous. > On Apr 22, 2020, at 1:51, Chris Belanger via 4D_Tech <4d_tech@lists.4d.com> > wrote: > > I have never used web areas in 4D so I will need to explore the benefits of > it.

Re: With v18r2, can 4D display pdf documents?
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. — Chris > On Apr 21, 2020, at 9:40 AM, kculotta via 4D_Tech <4d_tech@lists.4d.com> > wrote: > > This worked after adding the third / WA OPEN URL(*;"wa";"file:///Test.pdf") > >> On Apr 21, 2020, at 10:36 AM, kculotta via 4D_Tech <4d_tech@lists.4d.com> >> wrote: >> >> No one mentioned WA OPEN URL and a web area, which I thought would have been >> as easy as WA OPEN URL(*;"wa";"Test.pdf"), but that only resulted in a blank >> area. >> When I did get a pdf to open in the web area, all pages were available. >> Is that different than what you are asking? >> >> Keith - CDI >> >>> On Apr 21, 2020, at 12:14 AM, Chris Belanger via 4D_Tech >>> <4d_tech@lists.4d.com> wrote: >>> >>> Is there a way in 4D to display PDF documents?

Re: With v18r2, can 4D display pdf documents?
Used it for ages. On Mac no magic required, works out of the box, on Windows you might need to install Adobe Reader. On newer windows systems (win 10) i thinks it works right out of the box, but would have to verify... > Am 21.04.2020 um 18:36 schrieb Chris Belanger via 4D_Tech > <4d_tech@lists.4d.com>: > > That sounds like something I would really like to work.

Re: With v18r2, can 4D display pdf documents?
That sounds like something I would really like to work. If the web area knew what pdf renderer to use, it sounds like theoretically that should do it. Anyone know of how to get it to work? — Chris > On Apr 21, 2020, at 9:36 AM, kculotta via 4D_Tech <4d_tech@lists.4d.com> > wrote: > > No one mentioned WA OPEN URL and a web area, which I thought would have been > as easy as WA OPEN URL(*;"wa";"Test.pdf"), but that only resulted in a blank > area. > When I did get a pdf to open in the web area, all pages were available. > Is that different than what you are asking? > > Keith - CDI > >> On Apr 21, 2020, at 12:14 AM, Chris Belanger via 4D_Tech >> <4d_tech@lists.4d.com> wrote: >> >> Is there a way in 4D to display PDF documents?

Re: With v18r2, can 4D display pdf documents?
No one mentioned WA OPEN URL and a web area, which I thought would have been as easy as WA OPEN URL(*;"wa";"Test.pdf"), but that only resulted in a blank area. When I did get a pdf to open in the web area, all pages were available. Is that different than what you are asking?

Re: With v18r2, can 4D display pdf documents?
with a plugin-in http://www.pluggers.nl/product/pdf-viewer/ a web thingy https://mozilla.github.io/pdf.js/ --- I would consider the two above to be your top choices. I've posted a few convert-to-picture examples, but it sounds like you would want to render and display, not rasterise. https://miyako.github.io/2020/04/19/4d-plugin-xpdf.html https://miyako.github.io/2020/01/01/4d-plugin-pdfium.html > On Apr 21, 2020, at 14:14, Chris Belanger via 4D_Tech <4d_tech@lists.4d.com> > wrote: > > Is there a way in 4D to display PDF documents?
