2 | ||
3 | A wxImageList contains a list of images, which are stored in | |
4 | an unspecified form. Images can have masks for transparent | |
5 | drawing, and can be made from a variety of sources including bitmaps | |
6 | and icons. | |
7 | ||
8 | wxImageList is used principally in conjunction with \helpref{wxTreeCtrl}{wxtreectrl} and | |
9 | \rtfsp\helpref{wxListCtrl}{wxlistctrl} classes. | |
