Parameters:

parent (object) - Ignored, but present for compatibility with the Qt signal.
source_start (int) - The column number for the first column to be inserted.
source_end (int) - The column number for the last column to be inserted.

Note: We assume that all column insertions happen at the end of the alignment. This is consistent with the current behavior of the underlying models.

_columnInsertionOnColumnInsertion(self, old_source_cols, new_source_cols, source_cols_to_insert)

If the source model is inserting columns, determine if we need to insert columns into the proxy. This will only happen if source model started with fewer columns than the proxy's allowable width. If we need to insert columns, this method will call beginInsertColumns() with the appropriate values.

Parameters:

old_source_cols (int) - The number of source columns before the insertion.
new_source_cols (int) - The number of source columns after the insertion.
source_cols_to_insert (int) - The number of source columns to be inserted.

Returns: bool

True if we need to insert columns into the proxy. False otherwise.

_rowInsertionOnColumnInsertion(self, old_wrap_count, new_wrap_count, wraps_added)

If the source model is inserting columns, determine if we need to insert rows into the proxy. This will only happen if we've added enough columns that we need additional line wraps. If we need to insert rows, this method will call beginInsertRows() with the appropriate values.

Note that if we're adding rows and columns simultaneously and we need additional line wraps (which would happen if we added a new sequence that's longer than the current alignment length), then this method will handle the wrapped row insertions for the rows that are in the process of being added.

Parameters:

old_wrap_count (int) - The number of table wraps before the insertion.
new_wrap_count (int) - The number of table wraps after the insertion.
wraps_added (int) - The number of wraps that the insertion added.

Returns: bool

True if we need to insert rows into the proxy. False otherwise.

_dataChangedOnColumnInsertion(self, old_wrap_count, wraps_added, old_source_cols, new_source_cols)

If the source model is inserting columns, determine if we will need to emit a dataChanged signal. This will only happen if there were source columns insertions that won't trigger proxy row or column insertions.

Parameters:

old_wrap_count (int) - The number of table wraps before the insertion.
wraps_added (int) - The number of wraps that the insertion added.
old_source_cols (int) - The number of source columns before the insertion.
new_source_cols (int) - The number of source columns after the insertion.

Returns: bool

If we need to emit dataChanged, a tuple of:

The wrap number that we should emit dataChanged for (int)
The leftmost column for the dataChanged signal (int)
The rightmost column for the dataChanged signal (int)

None otherwise.

_emitDataChangedForColumnInsDel(self, wrap_num, col_start, col_end)

Emit the dataChanged signal for the specified wrap and columns.

Parameters:

wrap_num (int) - The wrap to emit the signal for. All rows in this wrap will be included in the signal.
col_start (int) - The leftmost column to emit the signal for
col_end (int) - The rightmost column to emit the signal for

_sourceColumnsAboutToBeRemoved(self, parent, source_start, source_end)

Respond to the columnsAboutToBeRemoved signal from the source model.

Parameters:

parent (object) - Ignored, but present for compatibility with the Qt signal.
source_start (int) - The column number for the first source column to be removed.
source_end (int) - The column number for the last source column to be inserted.

Note: We assume that all column removals happen at the end of the alignment. This is consistent with the current behavior of the underlying models.

_columnRemovalOnColumnRemoval(self, source_start, source_end, new_source_cols)

If the source model is removing columns, determine if we need to remove columns from the proxy. This will only happen if source model ended with fewer columns than the proxy's allowable width. If we need to remove columns, this method will call beginRemoveColumns() with the appropriate values.

Parameters:

source_start (int) - The column number for the first source column to be removed.
source_end (int) - The column number for the last source column to be inserted.
new_source_cols (int) - The number of source columns after the removal.

Returns: bool

True if we need to remove columns from the proxy. False otherwise.

_rowRemovalOnColumnRemoval(self, old_wrap_count, new_wrap_count, wraps_removed)

If the source model is removing columns, determine if we need to remove rows from the proxy. This will only happen if we've removed enough columns that we need fewer line wraps. If we need to remove rows, this method will call beginremoveRows() with the appropriate values.

Note that if we're removing rows and columns simultaneously and we need fewer line wraps (which would happen if we're removing the longest sequence), then the wrapped row removals for the sequences that are in the process of being removed have already been handled, so this method will avoid double removing them.

Parameters:

old_wrap_count (int) - The number of table wraps before the insertion.
new_wrap_count (int) - The number of table wraps after the insertion.
wraps_removed (int) - The number of wraps that the column removal removed.

Returns: bool

True if we need to remove rows from the proxy. False otherwise.

_dataChangedOnColumnRemoval(self, new_wrap_count, wraps_removed, old_source_cols, new_source_cols)

If the source model is removing columns, determine if we will need to emit a dataChanged signal. This will only happen if there were source columns removals that won't trigger proxy row or column removals.

Parameters:

new_wrap_count (int) - The number of table wraps after the removal.
wraps_removed (int) - The number of wraps that the insertion removed.
old_source_cols (int) - The number of source columns before the removal.
new_source_cols (int) - The number of source columns after the removal.

Returns: bool

If we need to emit dataChanged, a tuple of:

The wrap number that we should emit dataChanged for (int)
The leftmost column for the dataChanged signal (int)
The rightmost column for the dataChanged signal (int)

None otherwise.

_modelHeaderDataChanged(self, orientation, source_start, source_end)

Respond to a headerDataChanged signal from the model by emitting headerDataChanged

Parameters:

orientation () - The orientation of the header to update. Must be Qt.Horizontal.
source_start (int) - The index of the first source row where the header was changed
source_end (int) - The index of the last source row where the header was changed. Must equal source_start.

_modelDataChanged(self, source_left, source_right)

Respond to a dataChanged signal from the model by emitting dataChanged

Parameters:

source_left (QtCore.QModelIndex) - The left-most index to update
source_right (QtCore.QModelIndex) - The right-most index to update
