saving and restoring state doesn't work for this - they columns are always resized to fit their contents.

Any idea on how to fix this?

Hello,

Thanks for this great component !

Hello,

I'm not 100% sure that this is what you want, but you should be able to add extra items in the header.(I used the example 2 project, and modified it a bit, so it works with QT 5.3.2) The example 2 project only uses the horizontal header and i added 8 items.

Hope it helps you with what you want, and otherwise let me know, maybe i can help you.

Hello,

i'm using this application on qt 5.3.1 and i'm wondering if it's possible to hide the subcolumns of the horizontal header, but still make it possible for the root horizontal header element to span over multiple columns.

For now I sort of got a solution, I change the height of an item depending on the name/text. So if it's a subitem i set the height to 0, but the header will use the same height as when it contains the sub header column as well. So when hiding the subcolumns i want the height of the header to change as well.

So is there a better way to hide the subcolumns but keep the root column header spanning and change the height of the horizontal header to the height it is when only root items are used.

Ok I fixed the height of the header items by reimplementing the: virtual QSize sizeHint() const;

And i enabled the sort icon by adding:
if (isSortIndicatorShown() && sortIndicatorSection() == logicalInd)
opt.sortIndicator = (sortIndicatorOrder() == Qt::AscendingOrder) ? QStyleOptionHeader::SortDown : QStyleOptionHeader::SortUp;

to the styleOptionForCell funtion.

But when clicking on the horizontal header item that spans 2 columns the sortIndicator will only show for the whole button when i click on the right part. When i click on the left part the sortIndicator is shown half. Does anyone have a solution to make this working on only half the column item or both on the whole item?

A good app. I use it well, but it does't show sort indicator, or i have not find the right way?

First of all thank you for the great App!

I need to get a signal so that I could determine if a root cell or if a lower level cell has been clicked from the Headers and also get their QModelIndex. Something like QHeaderView::clicked(int) SIGNAL. Do you think that is possible? Any suggestions?

Thanks for creating a great widget. This worked great using Qt 4 but on Qt 5.1 I’m getting many strange compile errors such as:

HierarchicalHeaderView.cpp:382: undefined reference to `_imp___ZN11QHeaderViewD2Ev'

for function header:

HierarchicalHeaderView::HierarchicalHeaderView(Qt::Orientation orientation, QWidget *parent) :QHeaderView(orientation, parent), _pd(new private_data())

for instance. There are strange strings ie. “_imp___ZN11” and “D2Ev” embedded in the errors.

Has the widget been tested on Qt5 and is there an update that might work?

Sorry, I did not tested it on Qt5. Qt5 is not stable to me to use in production. I'll try to test the widget.

I have used this widget in our project and it works nicely.

Only problem I have is when I call resizeColumnsToContents() on the TableView, and the first root title is longer than all the child cells, the table looks funny. http://dl.dropboxusercontent.com/u/22456079/share%20images/columnsMinWidth.png The root segment text (in the picture's case "Power port (W)") is only partially displayed.

I was expecting the root segment's content to also be taken in consideration when adjusting leaf width's columns.

Any tips for adding a "minimum root cell width" feature?

Thanks for the great widget!

Is there a way one could resize sections from the code?

There is a resizeSection function in QTableView, but it has no effect on your widget.

Sorry, it was my mistake. I should have resized the sections after I set a model.

Hi, great work!

I extended your headerview allowing header sections to be clicked (setClickable(true)) - this worked just fine. Now I updated my Qt libs to the new version (4.7.3) resulting in the sectionClicked signal not triggered anymore. Usual QHeaderViews work just fine. Any ideas?
