# SDL\_SetTrayEntryLabel(3)

Sets the label of an entry.

## NAME

SDL\_SetTrayEntryLabel - Sets the label of an entry.

## HEADER FILE

Defined in SDL3/SDL\_tray.h

## SYNOPSIS

```
#include "SDL3/SDL.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.
