SrcInfo.CustDispTitle + Event (e.document.propsChanged, DocViewFlag_DisplayDocTitle) + IUIX_LayoutItem.Title[Prefix] SOLVED

[zarkogajic]

Hi Support,

When changing the IPXC_DocSrcInfo's CustDispTitle: e.document.propsChanged with DocViewFlag_DisplayDocTitle needs to be fired for the corresponding IPXV_Document so that its Tab grabs the change and updates its display. This all works as expected.

However, I also need to set the TitlePrefix of the document's tab IUIX_LayoutItem (which is the actual tab).

It seems that your internal update, after event fired, of the IUIX_LayoutItem Title happens in "async mode" after e.document.propsChanged BUT also removes TitlePrefix value - and the tab displays only the new Title and not the TitlePrefix.

Or, in (kind of pseudo) code:

Code: Select all

    Document.CoreDoc.SrcInfo.CustDispTitle := 'my new Title';

    evt := Document.EventServer.CreateNewEvent(e.document.propsChanged, Document, DocViewFlag_DisplayDocTitle);
    Document.EventServer.FireEvent(evt, Document);
    
    //here - e.document.propsChanged can be caught in pxvControl's OnEvent
    //but the Document.ActiveView.Obj.Parent.LI.Title is still the old one
    
    //then , this line should change the tab's title prefix but does not ... so the actual Title change and TitlePrefix reset happens later
    Document.ActiveView.Obj.Parent.LI.TitlePrefix := "some prefix";    

Reading Document.ActiveView.Obj.Parent.LI.Title just before the setter for Document.ActiveView.Obj.Parent.LI.TitlePrefix returns the old value of Title and not "my new Title".

Seems that the actual change of the tab's title happens "much" after the e.document.propsChanged can be caught.

And, as stated, new Title value resets my TitlePrefix value.

So, question: how/when to catch when the tab's title actually does get changed, and TitlePrefix, reseted, so I can set back the TitlePrefix to what I need it to be?

Hello zarkogajic,

The e_app_prefsChanged event is being fired and there the title update happens. Basically, you should obtain the IBitSet interface from the first param of the event and check whether the PXV_AppPrefsChange_Documents flag is set. If so, update the title prefix.

Cheers,
Alex

Hi Alex,

I've tried catching e_app_prefsChanged in PXVControl's OnEvent (event is registered for listening) - but it seems never to happen...

Btw, why would it be e_app_prefsChanged when changing document's CustDispTitle - as this is per document / not per app/instance.

Hello zarkogajic,

In my case, I've changed the title display settings on the application's level. Can you tell how to modify our UI so that your case happens, and I can see how our native code is being called?

Cheers,
Alex

Hi Alex.

This can be tested in Full Demo (having document's tab displayed and having a document loaded):

Code: Select all

pdfCtl.Doc.CoreDoc.SrcInfo.CustDispTitle = "my custom title";
//need to call this so that tab is updated, if not no change in tab's title
PDFXEdit.IEvent evt = pdfCtl.Doc.EventServer.CreateNewEvent(pdfCtl.Inst.Str2ID("e.document.propsChanged", false), 0, (uint)PDFXEdit.PXC_DocumentViewFlags.DocViewFlag_DisplayDocTitle);
pdfCtl.Doc.EventServer.FireEvent(evt, pdfCtl.Doc);

//-> here you can catch e.document.propsChanged, but "pdfCtl.Doc.ActiveView.Obj.Parent.LI.Title" is still the "original" title

//Now:
//only setting LI's TitlePrefix does not update it, must also set Title (reported as an issue in some other topic)
pdfCtl.Doc.ActiveView.Obj.Parent.LI.TitlePrefix = "my prefix";
pdfCtl.Doc.ActiveView.Obj.Parent.LI.Title = "my li title";

//here -> tab's title is again "my custom title" - so TitlePrefix value is lost.

p.s.
At the moment forum search is not working (?) - so cannot locate topics where pieces of the above are discussed.

Hello zarkogajic,

Investigated this behavior.
When you fire the e.document.propsChanged event, the timer for 250ms is being launched and then the UITitle is being updated.
Basically you can update the title afterwards by firing your timer.

Cheers,
Alex

Hi Alex,

Thanks. Btw, can you confirm that setting the CustDispTitle resets LayoutItem's TitlePrefix ?

Hello zarkogajic,

Firing the e.document.propsChanged resets all of the UITitle.

Cheers,
Alex
