194 | // Problem: | |
195 | // The MSW version had problems with SetTextColour() et | |
196 | // al as the wxListItemAttr's were stored keyed on the | |
197 | // item index. If a item was inserted anywhere but the end | |
198 | // of the list the text attributes (colour etc) for | |
199 | // the following items were out of sync. | |
200 | // | |
201 | // Solution: | |
202 | // Under MSW the only way to associate data with a List | |
203 | // item independent of its position in the list is to | |
204 | // store a pointer to it in its lParam attribute. However | |
205 | // user programs are already using this (via the | |
206 | // SetItemData() GetItemData() calls). | |
207 | // | |
208 | // However what we can do is store a pointer to a | |
209 | // structure which contains the attributes we want *and* | |
210 | // a lParam -- and this is what wxMSWListItemData does. | |
211 | // | |
