| | 24 | * wxImageList is used for wxListCtrl, wxTreeCtrl. These controls refer to |
| | 25 | * images for their items by an index into an image list. |
| | 26 | * A wxImageList is capable of creating images with optional masks from |
| | 27 | * a variety of sources - a single bitmap plus a colour to indicate the mask, |
| | 28 | * two bitmaps, or an icon. |
| | 29 | * |
| | 30 | * Image lists can also create and draw images used for drag and drop functionality. |
| | 31 | * This is not yet implemented in wxImageList. We need to discuss a generic API |
| | 32 | * for doing drag and drop and see whether it ties in with the Win95 view of it. |
| | 33 | * See below for candidate functions and an explanation of how they might be |
| | 34 | * used. |
