191 | // Problem: | |
73d8c5fd RD |
192 | // The MSW version had problems with SetTextColour() et |
193 | // al as the wxListItemAttr's were stored keyed on the | |
194 | // item index. If a item was inserted anywhere but the end | |
195 | // of the list the the text attributes (colour etc) for | |
7cf46fdb | 196 | // the following items were out of sync. |
73d8c5fd | 197 | // |
7cf46fdb | 198 | // Solution: |
73d8c5fd | 199 | // Under MSW the only way to associate data with a List |
43e8916f | 200 | // item independent of its position in the list is to |
73d8c5fd RD |
201 | // store a pointer to it in its lParam attribute. However |
202 | // user programs are already using this (via the | |
7cf46fdb | 203 | // SetItemData() GetItemData() calls). |
73d8c5fd RD |
204 | // |
205 | // However what we can do is store a pointer to a | |
206 | // structure which contains the attributes we want *and* | |
7cf46fdb | 207 | // a lParam for the users data, e.g. |
73d8c5fd | 208 | // |
