Detailed Description

On platforms that offer this concept, an SDL app can add a tray icon, submenus, checkboxes, and clickable entries, and register a callback that is fired when the user clicks on these pieces.

Typedef Documentation

◆ DetachedTrayEntry

using SDL::DetachedTrayEntry = typedef DetachedResource<TrayEntryRef, TrayEntry>

This is designed as resource types to cases where ownership might not be required.

◆ TrayCallback

using SDL::TrayCallback = typedef SDL_TrayCallback

Parameters

userdata	an optional pointer to pass extra data to the callback when it will be invoked.
entry	the tray entry that was selected.

Since: This datatype is available since SDL 3.2.0.

See also: TrayEntryBase.SetCallback

◆ TrayCB

using SDL::TrayCB = typedef std::function<void(TrayEntryRef)>

Parameters

entry the tray entry that was selected.

Since: This datatype is available since SDL 3.2.0.

See also: TrayEntryBase.SetCallback

◆ TrayEntryFlags

using SDL::TrayEntryFlags = typedef Uint32

Some of these flags are required; exactly one of them must be specified at the time a tray entry is created. Other flags are optional; zero or more of those can be OR'ed together with the required flag.

Since: This datatype is available since SDL 3.2.0.

See also: TrayMenu.InsertEntry

Function Documentation

◆ CreateMenu()

TrayMenu SDL::TrayBase::CreateMenu ( )

inline

This should be called at most once per tray icon.

This function does the same thing as TrayEntryBase.CreateSubmenu(), except that it takes a TrayBase instead of a TrayEntryBase.

A menu does not need to be destroyed; it will be destroyed with the tray.

Returns: the newly created menu.

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

Since: This function is available since SDL 3.2.0.

See also: TrayBase.TrayBase; TrayBase.GetMenu; TrayMenu.GetParentTray

◆ GetEntries()

std::span< TrayEntry > SDL::TrayMenu::GetEntries ( )

inline

Returns: a nullptr-terminated list of entries within the given menu. The pointer becomes invalid when any function that inserts or deletes entries in the menu is called.

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

Since: This function is available since SDL 3.2.0.

See also: TrayEntryRef.Remove; TrayMenu.InsertEntry

◆ GetMenu()

TrayMenu SDL::TrayBase::GetMenu ( ) const

inline

You should have called TrayBase.CreateMenu() on the tray object. This function allows you to fetch it again later.

This function does the same thing as TrayEntryBase.GetSubmenu(), except that it takes a TrayBase instead of a TrayEntryBase.

A menu does not need to be destroyed; it will be destroyed with the tray.

Returns: the newly created menu.

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

Since: This function is available since SDL 3.2.0.

See also: TrayBase.TrayBase; TrayBase.CreateMenu

◆ GetParentEntry()

TrayEntryRef SDL::TrayMenu::GetParentEntry ( ) const

inline

Either this function or TrayMenu.GetParentTray() will return non-nullptr for any given menu.

Returns: the parent entry, or nullptr if this menu is not a submenu.

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

Since: This function is available since SDL 3.2.0.

See also: TrayEntryBase.CreateSubmenu; TrayMenu.GetParentTray

◆ GetParentTray()

TrayRef SDL::TrayMenu::GetParentTray ( ) const

inline

Either this function or TrayMenu.GetParentEntry() will return non-nullptr for any given menu.

Returns: the parent tray, or nullptr if this menu is a submenu.

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

Since: This function is available since SDL 3.2.0.

See also: TrayBase.CreateMenu; TrayMenu.GetParentEntry

◆ InsertEntry()

DetachedTrayEntry SDL::TrayMenu::InsertEntry	(	int	pos,
		StringParam	label,
		TrayEntryFlags	flags
	)

inline

If label is nullptr, the entry will be a separator. Many functions won't work for an entry that is a separator.

An entry does not need to be destroyed; it will be destroyed with the tray.

Parameters

pos	the desired position for the new entry. Entries at or following this place will be moved. If pos is -1, the entry is appended.
label	the text to be displayed on the entry, in UTF-8 encoding, or nullptr for a separator.
flags	a combination of flags, some of which are mandatory.

Returns: the newly created entry, or nullptr if pos is out of bounds.

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

Since: This function is available since SDL 3.2.0.

See also: TrayMenu.AppendEntry; TrayEntryFlags; TrayMenu.GetEntries; TrayEntryRef.Remove; TrayEntryBase.GetParent

◆ UpdateTrays()

void SDL::UpdateTrays ( )

inline

This is called automatically by the event loop and is only needed if you're using trays but aren't handling SDL events.

Thread safety:: This function should only be called on the main thread.

Since: This function is available since SDL 3.2.0.
