some functions like TreeNode() implicitly creates a scope for you by calling PushID()
|
||||
- when dealing with trees, ID are important because you want to preserve the opened/closed state of tree nodes.
|
||||
depending on your use cases you may want to use strings, indices or pointers as ID. experiment and see what makes more sense!
|
||||
e.g. When displaying a single object, using a static string as ID will preserve your node open/closed state when the targetted object change
|
||||
e.g. When displaying a single object, using a static string as ID will preserve your node open/closed state when the targeted object change
|
||||
e.g. When displaying a list of objects, using indices or pointers as ID will preserve the node open/closed state per object
|
||||
- when passing a label you can optionally specify extra unique ID information within the same string using "##". This helps solving the simpler collision cases.
|
||||
e.g. "Label" display "Label" and uses "Label" as ID
