There is lots of function( arg ) instead of function(arg). ?besides that, some places could use more line breaks for readability (marked above).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Some API questions.
setSourceColumns seems to be used for both rearranging and filtering with no way to change individual columns (that i see). Eg, to toogle them or show/hide columns on demand.
Would it make sense to add the following API functions as well?</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">// toggle the visibility of a column
void toggleColumnVisibility(int column)
{
// pseudo code
setColumnVisible(column, !isColumnVisible(column));
}</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">// set the column visible or hidden, depending on the bool.
void setColumnVisible(int column, bool visible)</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">// returns if a column is visible
bool isColumnVisible(int column)</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Adding the above functionality would make it much more convenient to use in cases where you want to hide/show a column on the fly.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Toggle seems overkill (even QHeaderView doesn't have that), but the other two make sense. I'll add that (with QHeaderView naming).</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">If I do setSourceColumns(QVector<int>() << 2 << 1) and then setColumnHidden(2, true), I assume I'm hiding source-column-2, so the underlying vector becomes [1].
But if I now do setColumnHidden(2, false), where should column 2 reappear?
For the position to be kept, we would need (like QHeaderView) to distinguish reordering (visual<->logical mapping) and hiding (happens on top).
This makes the implementation more complex and error-prone IMHO. I think I'd rather let the program decide how it wants to handle that "vector of source columns". Maybe it's statically known (like in the first app I wrote this for), or it's replicating what a QHeaderView does at report-generation time (like in the app I'm writing this for right now, see FatCRM on github) (*), and only in a possible third case there would be a need for separating reordering and hiding...</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">(*) this reminds me, I wanted to add docu about how to replicate what QHeaderView does, using this proxy, but maybe this is only useful for use with KDReports...</p></pre>
