respected sir, I am kushagra sharma, I have been selected for GSoC'23. I am eager to add CPDB support to LibreOffice and would appreciate your approval to proceed with coding phase,by initiating the coding process promptly we can ensure a seamless integration of CPDB under GSoC's scheduled timeframe. Please feel free to share your thoughts on this project as we value your input and are committed work closely with you and deliver best possible outcome. It would be great help if i could have a mentor that can help me understand currently used print dialog in LibreOffice. Hoping for a kind consideration. thanks and regards Kushagra Sharma OpenPrinting On Fri, Apr 7, 2023 at 1:12 AM Caolán McNamara wrote: > On the technical side the things to look at might be: > a) The existing PrinterCapType::ExternalDialog "capability" which might > mesh with the concept here, which is used (in some circumstance > apparently) on macOS; git grep ExternalDialog vcl > b) The now removed (since migration from gtk2 to gtk3) experimental > integration to use the gtk print dialog.

Re: Print Dialog: Add support for the Common Print Dialog Backends (CPDB)
On the technical side the things to look at might be: a) The existing PrinterCapType::ExternalDialog "capability" which might mesh with the concept here, which is used (in some circumstance apparently) on macOS; git grep ExternalDialog vcl b) The now removed (since migration from gtk2 to gtk3) experimental integration to use the gtk print dialog. This was removed in commit 1ae450504cf57457f9702684b1517fda1dd3c481 but might be worth a look as something similar. FWIW back in that experimental gtk2 print dialog, one of the nuisances (and whose equivalent problem can be seen in a current version gnumeric) is that for spreadsheet printing the selection of sheets to print and/or cells couldn't be placed in proximity with the built in page ranges. In gnumeric, using the standard gtk dialog, they are placed a little awkwardly in a third tab, while in the LibreOffice non- standard dialog they are grouped into the "range and copies" category.

Re: Print Dialog: Add support for the Common Print Dialog Backends (CPDB)
Ilmari, thank you very much for taking this into the Engineering Steering Committee (ESC) meeeting today! And buovjaga to suggest this on IRC. Thorsten, thank you very much for your detailed meeting minutes and the quick posting of them. Heiko, there will be no UI change at all. The changes are only how the dialog gets - The list of available printers - For a printer selected by the user o The list of user-settable options with the available choices for each option (like Media Source: Tray 1, Tray 2, Bypass Tray, ...) o The list of all page sizes with unprintable margins, for correct previews o A job sent to the printer This will not done any more by the dialog directly talking to CUPS. but to the CPDB libraries. What the user sees and how they operate it will not change. This should not really be "massive" changes. As an example, here is the Merge Request for the CPDB support om the GTK dialog: https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/4930 And the commit on LibreOffice back in 2017, with the very first version of CPDB: https://gerrit.libreoffice.org/#/c/40565 Heiko, and thanks for stepping up to help mentoring on the UI/UX side, so if there is a change on the UI needed (low probablility) or the switch to CPDB would help for a better UI, your insight would help us a lot! Heiko, could you provide me your full name and e-mail address, so that I can invite you? Generally, we can invite and line up mentors at any time until the end of the coding, but I would appreciate a lot for anyone to step up before the ranking deadline, as the higher our number of mentors lined up, the higher the chances that we get our requested slot count, and so assure that very project we want to run will actually take place. Also the sooner we get someone stepping up, the sooner Kushagra can start working and has someone to talk to on the LibreOffice side. To step up, please tell me your full name and e-mail address, so that I can invite you and you can register in Google's web app. Only condition is that you do not participate as a contributor/student in this year's GSoC. I hope we will have a great collaboration here.
