Window Style

Meaning

L_ILS_OWNERDRAWITEM

This style must be used to make the ImageList Control an "Owner Draw" control. This style can be added when creating the ImageList control, using the L_CreateImageListControl function, or after it has been created by calling the Windows SetWindowLong function. When the ImageList Control is set to be "Owner Draw", then the parent window is responsible for drawing the contents of the control by processing L_ILM_DRAWITEM messages.

L_ILS_ZOOMSMALLITEMS

This style can be used to indicate that images that are smaller than the size of an ImageList Item will be zoomed to fit the ImageList Item. By default, images that are smaller than an ImageList Item are displayed at their natural dimensions.

L_ILS_CENTERVERTICAL

This style can be used to indicate that images should be centered vertically in an ImageList Item.

L_ILS_KEEPCOMPRESSED

This style can be used to indicate that images for ImageList Items are kept compressed in memory (to reduce memory usage).

L_ILS_ACCEPTDROPFILES

This style can be used to indicate that the ImageList Control can handle WM_DROPFILES messages. This allows users to add items to the ImageList Control by dragging and dropping supported image files from Explorer.
