#79 hide and move columns and rows in table view

[Lina Humbeck]

It would be nice to move and hide columns and rows in the table view to bring columns/rows of interest together and neglect these of no interest.

[Till Schäfer]

• moving columns is already implemented: just use drag and drop.
• moving rows is only possible by sorting so far
• row hiding can be done by creating a subset

[Nils Kriege]

Hiding columns is highly desirable. Fingerprints should be hidden by default.

[Till Schäfer]

is manual hiding necessary or should we just hide the fingerprints? It is still possible to move the interesting columns to the left.

[Nils Kriege]

I would prefer a panel that allows the user to decide which columns should be displayed. Something similar to the 'propety list' at the left side bar of the heat map view would be nice.

[Till Schäfer]

ok, then we can also do sorting like in the heat map (additionally to the classical sorting over the column headers)

[Philipp Mewes]

I thought of something similar. Implemented a first draft here: [5b11f0]. Currently i'm looking for a way to connect the sidebar-item and the table-view.

[Philipp Mewes]

Added a list at the sidebar, which allows to change the order and show/hide columns (see [1fc600] and preceding commits).

[Philipp Mewes]

Some bugs:
(1) Properties disappear from the list, if they are currently hidden in the table and the column-order is changed per drag-and-drop. The properties cannot be restored in the list. (Fixed: [b6fa5f])
(2) If some columns are hidden, and the sort-button is pressed, all values in the list are checked, including hidden properties. This does not reflect the current table-state and should be changed.

[Philipp Mewes]

(2) Fixed this ([8dce0a]),

(3) If some columns are made sticky and the property-order is changed, the columns that are always visible are duplicated.

[Philipp Mewes]

(3) Fixed by [4a8aa9]

[Philipp Mewes]

(4) After applying a filter, the hidden columns are displayed checked at the filter (Fixed by [810ce8], also the order at the filter is kept now).

[Philipp Mewes]

As desired, fingerprints are hidden by default now ([ff8634]).

[Philipp Mewes]

Can You please review, whether the feature fits the requirements? If everything is ok, i will add a respective subsection to the manual.

[Nils Kriege]

• the height of the widget should be increased (double the size of the checkbox field)
• the buttons should be arranged properly, particularly when the width of the sidebar is increased
• the apply button should be highlighted in red whenever the current selection is not applied in the current view (compare other views)
• the settings should be preserved when changing the subset
• there are five properties (Title, SMILES etc.) which cannot be unchecked. I understand that these are not standard properties in th db, but from a user perspective, there is no difference. Can we include these in the list?
• Sticky coumns are reset when clicking apply

[Philipp Mewes]

(2) Updated the layout ([0a0b4d]).

[Philipp Mewes]

(1) Doubled the height of the widget ([8cfa80])
(3) Apply-button is highlighted red now, when the filter changes ([06c05c])

[Philipp Mewes]

(4) Implemented this with this commit: [eb6485]. There might be some cleanup to do in the model, because the ColumnFilter almost completely provides the data to display now.

[Philipp Mewes]

(5) These special columns can be unchecked now too ([a464e6]).

[Philipp Mewes]

(6) Sticky columns are preserved now ([d1cb5f]).

[Philipp Mewes]

Updated the manual ([ef637a]).

[Philipp Mewes]

There was a small problem with the sort-button. If the columns were sorted, the initial order (special-columns at the top of the list) could not be restored. Fixed this by introducing a new button ([e1204e]).
