I have committed a gb.gtk ComboBox patch in revision 1530. Here is some little benchmarks on my Dual Core. 1) Before the patch. Filling a combo-box with 1000 items: 0.474 s Then reading the Count property 100000 times: 15.650 s Filling a sorted combo-box with 1000 items: 170.95 s Then reading the Count property 100000 times: 18.43 s 2) After the patch. Filling a combo-box with 1000 items: 0.0125 s Then reading the Count property 100000 times: 0.0162 s Filling a sorted combo-box with 1000 items: 0.0224 s Then reading the Count property 100000 times: 0.0164 s 3) Same thing with the gb.qt component. Filling a combo-box with 1000 items: 0.0014 s Then reading the Count property 100000 times: 0.0157 s Filling a sorted combo-box with 1000 items: 2.782 s Then reading the Count property 100000 times: 0.0169 s The patch tries to delay all heavy GTK+ process as much as possible when adding items. If I did not make any bug, other properties and methods should work as expected. gb.qt is still the fastest, except when the combo-box is sorted. But maybe I can do the same optimization there than I did in gb.gtk. And searching is not possible yet.
