    Default Changing only the parent and font-size of QstyledItemDelegate's Editor

    I've implemented a class derived from a QStyledItemDelegate so that I can present a custom widget for editing some columns of QSqlTableModel / QTableView. That's working.

    The default editors for most columns are QSpinBoxs. That's fine, except I want them bigger. So, the editor's parent needs to be 0 and the font size needs to be much larger than the default (which sizes nicely to fit in the TableView row, but is too small for touch applications).

    I did this for the columns with custom widgets and could do the same for these other columns. But, is there a way to change only the parent of the default editor and the font point size so I don't have to have totally custom widgets for these too?

    I tried using the QStyleOptionViewItem passed in the virtual QStyledItemDelegate::createEditor method for setting the font size. But it's a const &, so I can't change it in my implementation.

    Thanks,

    Dave Thomas

    You can create a local copy and modify that.

    Qt Code:
    1. QStyleOptionViewItem myOption = option;
    2. // modify myOption
    To copy to clipboard, switch view to plain text mode
