# 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.)
