Elide modes for QTreeView ,QStandardItemModel

[kiran p]

Hello Everyone,

I've come across a challenge when Using model view Architecture (QTreeView ,QStandardItemModel)
where in i need to set different Elide modes for different columns in a tree view
for eg column 1 setTextElideMode(Qt::ElideRight);
column 2 setTextElideMode(Qt::ElideLeft);
column 3 setTextElideMode(Qt::ElideMiddle);

Please respond! thanks in advance..

You can use different modes by using a custom delegate. Subclass QStyledItemDelegate or QItemDelegate and use different values for different columns of the model. QFontMetrics::elidedText() will help you.

Have a look at QStyledItemDelegate::paint() and QStyleOptionViewItem. All you need to do is to set the text elide mode of the option you are given based on the column of the index and call the base class implementation with the modified option.
