hi every one.
i’m doing at desktop app i would like use into DataViewListCtrl a FloatSpin control then i was making my custom DataViewFloatSpinRender who extends from DataViewCustomRender(see code below), then i was making my model who is DetalleVentaVirtualListModel who extend from DataViewVirtualListModel.
My question is next when exceute my app dont show the FloatSpin control class? thank to all for read it
==============other class who addColumn into DataViewListCtrl===============
