# Images in Tables and Trees
In yet another "blame Windows" moment:
```go
type ImageList interface {
Add(image *image.Image)
Remove(index int)
Len() int
}
func NewImageList() ImageList
type Table/Tree interface {
// ...
LoadImageList(ImageList)
}
type ImageIndex int
```
For Table, a field of type ImageIndex represents an index into the ImageList.
For Tree, there is a field ImageIndex which contains the index of the entry.
Note the name of the methods on both being LoadImageList(): the image list is copied, and any future changes will **not** be reflected. (This is to accomodate check boxes in Table, which must be done manually.)
Icons scale automatically to the best possible size.
On Windows this is GetSystemMetrics(SM_CX/YSMICON)
On GTK+ this will be determined by trial and error
[11:14] <LiamW> andlabs: probably
[11:14] <LiamW> GTK_ICON_SIZE_SMALL_TOOLBAR
[11:15] <baedert> the procedure is to just try all of them and see what looks best :p
On Mac OS X this is rowHeight
TODO which side does the scaling, C or Go?
