&& orientation == Qt::Horizontal, looks weird in a QTableView otherwise ;)
Looks good in general, feel free to merge. |
Properly fwd declare Ui_PropertyWidget in propertywidget.h, also, don't try to use the probe if it it isn't initialized.
Not QObject.
The property widget may now contain the following pointers: * QObject instance * Non-QObject instance, with meta type * QMetaObject instance Also: Don't enable/disable the tabs when they're unused, properly show/hide them
Merged to master. |
