hi,

i have a QTreeWidget which shows the hierachy of a model. this model
has lots of items (>10000). the items can be selected in the tree widget and
in a 3D OpenGL view. when an item is selected in the 3D view the associated
treewidget item should be selected as well. this is done by reacting on a signal
and calling setItemSelected of the tree widget. well since selecting of items
by itself is quiet ok it gets really slow when i call setItemSelected.
how can i speed up selecting/deselecting of items in a qtreewidget?

i used the abstractview class before but found it too complicated, so i
would like to stay with QTreeWidget.

best regards,
jh
