[GUI Plugin] View Manager

[drawson1]

I'm using the current version of Calibre (3.14) and the View Manager plugin. I set up my new "default" view, and modified the sort, column widths, etc., then did "Save columns, widths and sorts". I set View manager to automatically apply the view at startup.

When I re-start calibre, the view is checked in ViewManager, but is only partially applied. I see my desired sorts and columns, but the column widths are wrong. If I click the view name in the ViewManager menu, THEN it's fully applied.

See the attached pic . . . .

How can I get this to (fully) apply at startup?

Thanks!

Moved to where it belongs, from Library Management back to Plugins

drawson1, I can reproduce your issue, but I'm not sure anything can be done about it.

VM is attempting to set the column order and sizes when the plugin's initialization_complete() is called. However, I don't think Calibre has finished setting up and displaying the library view yet and so the sizes are being ignored/replaced.

Personally, I set a keyboard shortcut for my most used view to 'spacebar'.

@JimmXinu: I dont think any library view layouting is done after initialization_complete (it is called at line 409 in gui2/ui.py which is close to the end of that method). You can insert a print there and also a print in the apply_state function in library/views.py which is where the column layout for the book list is restored, to check.

@kovidgoyal, I was just speculating as to the cause.

The same code in VM applies column size at start up (initialization_complete()) and library switch (library_changed() calls initialization_complete()). On library switch, the sizes are applied, on start up they are not. I don't see how anything the plugin does could change that.

[drawson1]

Did that, so I have a quick work-around :-), thanks!

Has anyone started thinking about how View Manager and the new "Split the book list" feature interact? And how they should interact?

Some quick initial testing seems to show VM effecting only the left side of the split list.

Sort of - see https://www.mobileread.com/forums/sh...5&postcount=17 and following post between KG and me.

I haven't installed 3.17. Does Split View (SV) effect VM if you don't use SV, if it does I won't install the new version - my problem is that I don't use the latest VM because of the changes made last year.

I have calibre 3.17 and VM (last version). No change (without using SV, I don't know with SV because I see no use for me at this moment).

I imagine that's what most folks would expect/want.

Thanks - same for me, no current use for SV. I could have used it last year, and the year before, and ... but my old 'job' of collecting, cataloguing, and converting 'interesting' o'seas documents has been outsourced to the crew who do the domestic documents - at my request (insistence).

Here's what I've found:

        # Internally, the second split view is referred to as the 'pin_view'.  
        # state can be gotten and appears the same as library_view.
        state = self.gui.library_view.get_state()
        pin_state = self.gui.library_view.pin_view.get_state()

        # it looks like apply_state(state) will also work the same.
        state = {'hidden_columns': hidden_cols,
                 'column_positions': positions,
                 # no sort_history in pin_view
                 'column_sizes': resize_cols}
        self.gui.library_view.pin_view.apply_state(state)

        # showing/hiding the pin_view is easy:
        # self.gui.library_view.pin_view.isVisible()
        self.gui.library_view.set_pin_view_visibility(bool)

As far as I can tell, calibre saves *whether* the view is split(), but doesn't save *where*. IE, on restart, the split bar is centered regardless of where it was last dragged. Is that intended, I wonder?

So saving and applying column data for both sides in View Manager looks doable, as does showing/not showing the splitter. Placement of the splitter, I haven't figured out.

Integrating split on/off and a second 'Columns in View' list in the plugin config dialog would be the hardest part.

[kovidgoyal]

Splitter state is most definitely saved, see pin_columns.py PinContainer.save_state()

[JimmXinu]

Kovid, I did see that, which is why I wonder if it's working correctly.

Whether the view is split or not is saved across calibre restart, but the right-left location of the splitter bar is not kept for me when I restart calibre.

Steps:

1. Split book list
2. Drag splitter bar right or left
3. Restart calibre
4. Splitter bar is there, but back in the center

[kovidgoyal]

Works fine for me. And according to the qt docs saveState() saves the entire layout, https://doc.qt.io/qt-5/qsplitter.html#saveState

[JimmXinu]

Hrm. It worked for me for a bit after uninstalling VM, then reset to center when I installed VM again, but now it doesn't work even after I removed VM again.

In fact, even while running with `calibre --ignore-plugins` I'm still seeing the split bar reset to center on restart.

So while it might be something to do with my computer, I don't think it's anything to do with the plugin...
