How is it possible to confine a selection to a single row?
Most of the code is inspired/copied from the demo virtual > Gallery.
Right now I have:
new qx.ui.virtual.selection.CellRectangle(scroller.getPane(), this).set({
mode: "multi",
drag: true
});
Which works well. However, I'd like to confine the selection to the row
that the selection(drag) was started on. So in other words, one should
not be able to select vertically. I had an idea to use the
isItemSelectable method and store the first cell that was clicked on,
and then use that as a reference to restrict further horizontal
selection, but I don't know if that is the best way to do it.
Perhaps something like:
isItemSelectable : function(item)
{
if (item.row == this.startSelectionRow) return
!!this.items[item.row][item.column];
else return false;
}
Any ideas and tips are much appreciated.
Thanks,
Simon
