ImGui.SetNextWindowSizeConstraints

SetNextWindowSizeConstraints(
    size_min: ImVec2Like,
    size_max: ImVec2Like,
    custom_callback?: null,
    custom_callback_data?: null | bigint,
): void
Set next window size limits.

Parameters
size_min
ImVec2Like
Minimum window dimensions in pixels. Use -1 for both limits on an axis to preserve that dimension.

size_max
ImVec2Like
Maximum window dimensions in pixels; 3.4028234663852886e+38 removes the upper limit. Paired -1 limits preserve an axis.

custom_callback
null = null
Leave null; window size-constraint callbacks are not exposed to JavaScript. Passing a function throws a TypeError.

custom_callback_data
null | bigint = null
Opaque callback user-data address; unused when the callback is null.

Returns
void
Remarks
use 0.0 or 3.4028234663852886e+38 if you don't want limits.

Use -1 for both min and max of same axis to preserve current size (which itself is a constraint).

The binding supports these numeric limits only. Upstream Dear ImGui also supports size-constraint callbacks, but this API has no JavaScript callback adapter.
