Oops, WStandardItemModel::clear() was not triggering the proper signals. Might be because an appropriate signal (modelReset()) was not yet provided by WAbstractItemModel. All that has been fixed in the latest git. > Column 0 Header > ------------------------- > > Also, I have an ongoing issue with the format of headers in column 0. > It seems to me that setting the column 0 width does not work - it > always takes the remaining space.

Apparently I forgot to implement the column 0 resizing, this has been fixed in git. In IE, it is indeed the case that header gets lost when rendered too small -- we have not yet found a workaround for this problem. > And finally where a table is added and removed from a container > (scenario: different menu options are selected and I am displaying > different content) - then column 0 header text is not rendered the > second (or perhaps third) time. That is strange. Could you make a small test case for this ? > Suggestions > ------------------ > - I do not use CSS but rather want to use the layout managers.

Perhaps some > clearer guidance could be added to the doc? The doc is indeed not clear: resize() indeed specifies the CSS size. The CSS size is used for widgets whose size is not managed by a layout managers. This thus includes the size of a widget whose contents is managed by a layout manager. Minimum/Maximum size is taken into account by layout managers for widgets it manages -- but there may be problems with this (as IE does not implement this well). What issues do you see, which browsers, and could you turn them into a reproducible test case ? > - I understand why you have done it this way but I find it strange to > add the headers in the Model - I feel that the header text should be > in the [tree] view. (The real reason why I have done it this way is because Qt has done it this way). I would agree with the Qt way though -- the view should not be concerned with any contents, and headers are as much part of the contents as the data itself (as it provides the context for the data) ? You could implement a proxy model which overrides the headers for another model, if you want to manage/override the headers suggested by a model with custom headers.
