How can I remove the default images on the TIWTreeView (in Delphi 2007)? The closed book, open book and the leaf page images. I know I can set them to other custom images, but when I try even just a 1x1 blank image it leaves a 16x16 space for the image. I just want the (+) and (-) images in the tree, with no open/closed/leaf graphics.
Thx.
