Check the "API BREAKING CHANGES" sections for a list of occasional API breaking changes. If you have a problem with a function, search for its name
in the code, there will likely be a comment about it. Please report any issue to the GitHub page!
Q: Can I have multiple widgets with the same label?
Q: Can I have multiple widgets with the same label? Can I have widget without a label? (Yes)
A: Yes. A primer on the use of labels/IDs in ImGui..
- Elements that are not clickable, such as Text() items don't need an ID.
- Interactive widgets require state to be carried over multiple frames (most typically ImGui often needs to remember what is the "active" widget).
to do so they need an unique ID. unique ID are typically derived from a string label, an integer index or a pointer.
Button("OK"); // Label = "OK", ID = hash of "OK"
Button("Cancel"); // Label = "Cancel", ID = hash of "Cancel"
- Elements that are not clickable, such as Text() items don't need an ID.
- ID are uniquely scoped within windows, tree nodes, etc. so no conflict can happen if you have two buttons called "OK" in two different windows
or in two different locations of a tree.

Button("Play##0"); // Label = "Play", ID = hash of "Play##0"
Button("Play##1"); // Label = "Play", ID = hash of "Play##1" (different from above)
- so if you want to hide the label but need an ID:
Checkbox("##On", &b); // Label = "", ID = hash of "##On"
- occasionally (rarely) you might want change a label while preserving a constant ID. This allows you to animate labels.
use "###" to pass a label that isn't part of ID:
