Class: TEgDBGridEx
property Images: TCustomImageList;Image list supplying the icons drawn by OnBeforeDrawTitle
(title cells), OnBeforeDrawCell
(any data cell, via its
ImageIndex/ImageAlignment output), TEgColumn’s own ImageIndex/ TitleImageIndex
properties, and CornerImageIndex
(the fixed corner cell). Not owned or freed by the grid; automatically
set back to nil if the assigned image list is destroyed
first (for example, removed from the form or freed at runtime),
preventing a dangling reference on the next repaint.
This is separate from a graphic/BLOB field’s own image content (JPEG,
PNG, Bitmap, Icon, GIF or Metafile) - see DetectBlobImages
to also try a plain BLOB field), which is decoded straight from the
field and needs no entry in Images. Either kind of image,
when larger than the space available to it, shrinks to fit with its
aspect ratio preserved rather than being skipped - including the corner
cell image (see CornerImageIndex),
which follows the same rule. Transparency is respected for every
field-content format that carries it (PNG, GIF, Icon, and a 32-bit
Bitmap with a genuine alpha channel); an ordinary opaque Bitmap (24-bit,
or a 32-bit one whose alpha byte is unused) is unaffected.
Images icons themselves are drawn the same transparent way,
including when overlaid on a decoded field image - see ImageIndex.
