SDL_SetTrayEntryLabel - Man Page

#include <SDL3/SDL_tray.h>

void SDL_SetTrayEntryLabel(SDL_TrayEntry *entry, const char *label);

An entry cannot change between a separator and an ordinary entry; that is, it is not possible to set a non-NULL label on an entry that has a NULL label (separators), or to set a NULL label to an entry that has a non-NULL label. The function will silently fail if that happens.

entry

the entry to be updated.

label

the new label for the entry in UTF-8 encoding.

This function should be called on the thread that created the tray.

This function is available since SDL 3.2.0.
