Qdoublespinxbox, to calculate a subtotal ( col1 * col2 )

every time the value of Qdoublespinxbox changed i will update the value subtotal

Solution

  • you can add signal to your QStyledItemDelegate subclass, emitted in setModelData() reimplementation. Signal should have information about new value and possible locate of data. In other class catch that signal and update the value subtotal.
