166 | // Problem: | |
167 | // The MSW version had problems with SetTextColour() et | |
168 | // al as the wxListItemAttr's were stored keyed on the | |
169 | // item index. If a item was inserted anywhere but the end | |
170 | // of the list the the text attributes (colour etc) for | |
171 | // the following items were out of sync. | |
172 | // | |
173 | // Solution: | |
174 | // Under MSW the only way to associate data with a List | |
175 | // item independent of its position in the list is to | |
176 | // store a pointer to it in its lParam attribute. However | |
177 | // user programs are already using this (via the | |
178 | // SetItemData() GetItemData() calls). | |
179 | // | |
180 | // However what we can do is store a pointer to a | |
181 | // structure which contains the attributes we want *and* | |
182 | // a lParam for the users data, e.g. | |
183 | // | |
184 | // class wxListItemInternalData | |
185 | // { | |

187 | // wxListItemAttr *attr; | |
188 | // long lParam; // user data | |
189 | // }; | |
190 | // | |
