Whoops, you're right. I misunderstood the purpose of gtk_widget_reparent.

Here's the patch v2.

We no longer need to hide the inputbar to get the right jump position,
since now showing or hiding the inputbar does not change the position
stored in the document object.

Wen the adjustments get resized, the changed_callback resets the value
from what is stored in the document object, effectively recentering the
position to the middle of the viewport.

The callbacks are no longer aware of it anyways

They are not used anywere, and do not seem to become useful anymore in
the light of the new separation of document and view.

We don't need the anymore since the new page_set and position_set are
already 'delayed'.

And get rid of explicit gtk calls to the adjustment

We get the position data from the document object instead of the gtk
adjustment itself.

The new page_set and position_set behave as delayed, but with the
immediate availability of the new positions through the document
object. We no longer need to keep delayed and non-delayed versions!

The adjustment callbacks act as an interface between position data in
the document object, and the adjustments.

We remove the horizontal centering code, as now it is done by
position_set. Those callbacks should not change the position read from
the document object in any way.

Also, we split the adjustment_value_changed callback into a vertical and
an horizontal version. Previously a single callback was reused for both,
horizontal and vertical. That lead to a subtle problem when coming out
of index mode. What happened was the following:

  1. horizontal adjustment bounds change coming out of index mode. This
     triggers an hadjustment changed signal.

  2. the hadjustment_changed callback handles it, and resets the
     hadjustment value, as the bound may have changed. This triggers a
     value_changed event.

  3. the value_changed callback handles the event, and captures the
     position for *BOTH*, horizontal and vertical adjustments, saving
     them to the document object.

  1..3 is repeated for the vertical adjustment.

  Now, if in 3. the horizontal adjustment bounds were not yet updated
  after the index mode, we got ourselves at the wrong vertical position.

This race condition is avoided now because both value_changed callbacks
*ONLY* handle their own direction, either vertical or horizontal, not
 both.

This new function adjust_view is in charge of recomputing the scale
according to adjustment settings and trigger a render_all.

adjust_view contains the old sc_adjust_window code, slightly simplified
thanks to the availability of the document_get_viewport_size.

Then it is used by sc_adjust_window, document_open and the
cb_view_resized callback. Makes slightly more sense this way than
calling the shortcut sc_adjust_window directly.

Now page_set and position_set save the computed page and position to the
document object, then trigger a refresh-view signal. They do not handle
GTK adjustments anymore.

Now we can trigger a gtk page refresh calling refresh_view. This
function triggers a custom signal refresh-view, whose handler copies the
position from the document object to the adjustments.

  - fix the computation of the number of rows in the table. Doing a ceil
    of an integer division has no effect...

  - set the page_padding in page_widget_set_mode function, instead of
    doing it independently.

  - call zathura_document_set_layout after calling page_widget_set_mode
    to save the page layout settings into the document object.

now accepts a document object and explicit width and height. This will
make it easier to reuse this function for computing the document page
cell width and height.

The page widget shouldn't have to care what should be done with selected images
