NAME
SDL_SetTrayEntryLabel - Sets the label of an entry.
SYNOPSIS
#include <SDL3/SDL_tray.h>
void SDL_SetTrayEntryLabel(SDL_TrayEntry *entry, const char *label);
DESCRIPTION
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.
FUNCTION PARAMETERS
entry the entry to be updated.
label the new label for the entry in UTF-8 encoding.
THREAD SAFETY
This function should be called on the thread that created the tray.
AVAILABILITY
This function is available since SDL 3.2.0.
