(Bookmark) Panes: show/hide/check visible SOLVED

[zarkogajic]

Hi,

Say I want to show the Bookmarks pane from code, I can use: "Inst.ExecUICmd2(IDFOR("cmd.view.bookmarks"))".

Executed once bookmark pane will get displayed, executed again, it will get hidden.

I want to get if the pane is visible or hidden then show if hidden, hide if visible...

It seems I can read the state (PXV_Control.Doc.ActiveView.BookmarksView.Obj.Visible) but am not sure how to set it.

Also, I see I can use

PXV_Control.Doc.ActiveView.Panes.Show/Hide(IPXV_View)

but how do I go from string "bookmarksView" to the IPXV_View?

Hi devs,

To answer my question (with an additional question at the end):

Bookmarks view is accessible only when a document is loaded - so you cannot show/hide without at least one document - this is how it works in the EndUser Editor.

According this: viewtopic.php?t=31474#p127467
To show/hide/change title/do other stuff with the bookmarksview (and other document-panes like PageThumbsView, AttachmentsView, LinksView and the rest) you can get the IUIX_LayoutItem, like:

Code: Select all

uiLItem : IUIX_LayoutItem;
...
uiLItem := PXV_Control.Doc.ActiveView.Panes.Layout.GetItem(PXV_Control.Doc.ActiveView.BookmarksView.Obj);

Then you can do things like

Code: Select all

uiLItem.Title := 'XXX';
uiLItem.Show;
uiLItem.Hide(false);

Btw, if you have multiple documents or even multiple MainFrames (that is multiple pxv_Controls) you might want to go for the below setting - as hiding/showing the pane for one document will not also hide/show for the other(s):

Code: Select all

  Inst.Settings['Docs.AutoSyncDocPanesLayouts'].v := false;
  Inst.FireAppPrefsChanged(PXV_AppPrefsChange_Documents, nil);

Now, the tricky part is how to get notified when the view is set to be visible or hidden. For this you have to implement a custom IUIX_ObjImpl handler as in here: viewtopic.php?f=66&t=26067&hilit=Pane+show#p101658

Now, since one can access the BookmarksView object only when there's a document, the Obj sent to custom event handler is PXV_Control.Doc.ActiveView.BookmarksView.Obj - and this view is tied to that document.

So, when to instantiate the custom handler? My approach is in "e.document.viewingStarted" - as this is when you have the document and when you have an ActiveView - and (seems so far) this event fires only once per document.

Inside IUIX_ObjImpl's OnEvent implementation you go with "if pEvent.Code = e_Visible" and the Obj gives you the info you need (set visible, etc).

The thing is that if you load another document - the event does not get fired - as the BookmarksView.Obj for the second document is not the same as for the document you are custom event handling.

For the second document (and any other loaded) one needs to instantiate another instance of IUIX_ObjImpl for that document's BookmarkView.Obj - when "e.document.viewingStarted" as stated above.

Can this be confirmed by support-devs?

Hello žarko,

So, when to instantiate the custom handler? My approach is in "e.document.viewingStarted" - as this is when you have the document and when you have an ActiveView - and (seems so far) this event fires only once per document.

This would be OK.

An also yes, you will have to make an array of command handlers for each of the Bookmarks Views - then everything will work for you.

Cheers,
