StateImages: IImageList;
The StateImages property determines a list of images that are used to identify the state of elements of the tree of the TreeList and TreeCombo components.
All ImageList and GlobalImageList components placed on the form are included to the list of available values.
If the StateImages property is set for the component and Checkboxes = True, two first images of the StateImages collection are used to display the checkbox state (selected or deselected) for the elements. The images with the 0 index are used for the deselected checkboxes, the image with the 1 index is used for the selected checkboxes.
