IPXV_PagesLayoutManager::Navigate with PLNavigate_Backward/PLNavigate_Forward (and in IPXV_PagesPreviewCtl) SOLVED

[zarkogajic]

Hi Support,

I'm trying to mimic what executing "cmd.view.goto.[prev|next]View" does via code and not by executing commands.

I've tried using ipxvDocument.ActiveView.PagesView.Layout.Navigate(PLNavigate_Backward, 0) for an IPXV_Document but it only goes one page back (same for PLNavigate_Forward - goes to next page). There is navigation "history".

Doing "the same" via ExecCmd does work:
InstUI.CmdManager.ExecCmd('cmd.view.goto.prevView', ipxvDocument.ActiveView.PagesView.Obj);

I, actually, need backward/forward to work with IPXV_PagesPreviewCtl.

Executing InstUI.CmdManager.ExecCmd('cmd.view.goto.[prev|next]View', IPXV_PagesPreviewCtl PPC) does nothing.

So:

[Q1] Is view navigation not supported by IPXV_PagesPreviewCtl?

[Q2] How to correctly call Navigate method for an ipxvDoc?


p.s.
If it makes any sense I'm also setting "NavHistory.Global" to false (as I do not want global navigation / only per document)

Hello zarkogajic,

In the IPXV_PagesPreviewCtl interface you have the CurrentPage available that you can set to your liking.
The IPXV_DocumentView gives you the https://sdkhelp.pdf-xchange.com/vi ... _PagesView.
And the IPXV_PagesView has the CurrentPage property that you can modify according to your needs.

Cheers,
Alex

Hi Alex,

Thanks, but unfortunately not the answer to my question.

To repeat - and I'm asking specifically about: PLNavigate_Backward and PLNavigate_Forward.

[Q1] Is (view history) navigation not supported by IPXV_PagesPreviewCtl?

[Q2] How to correctly call Navigate method for an ipxvDoc?

Hello zarkogajic,

The thing is that this is not a PagesPreviewCtl (it's being used for preview - for example Watermarks dialog) - it's just a PagesView. The commands that you are executing are doing the exact same thing as you describe:

Hi Alex,

I know PagesView inside MainView/DocumentViewArea is not PagesPreviewCtl.

Please read my post in detail, I have asked two separate questions.

1. For the "standard" pxvDocument.ActiveView.PagesView, having navigation history, Layout.Navigate(PLNavigate_Forward) moves to next (+1) page while PLNavigate_Backward to prev page (-1). Executing InstUI.CmdManager.ExecCmd('cmd.view.goto.prevView', ipxvDocument.ActiveView.PagesView.Obj) does work correctly - goes back to the page in navigation history.

2. For PagesPreviewCtl both above approaches move to next page (+1) / prev page (-1).

Hello zarkogajic,

Just checked the inner structure - there are different implementation classes used for the Layout of the PagesPreviewControl and the PagesView. Thus the behavior can differ as the Navigate method is not the same for PLNavigate_Backward and PLNavigate_Forward method. The problem can lie in the Page Layout mode as it differs in code.

Cheers,
Alex

Hi Alex,

Thanks. I'll close the topic and reopen if needed later. For the moment I've found a workaround.
