## **PROTOCOLS**

## FontSetEventListener {#FontSetEventListener}
*Defined in [fuchsia.fonts/events.fidl](https://cs.opensource.google/fuchsia/fuchsia/+/main:sdk/fidl/fuchsia.fonts/events.fidl;l=9)*
<p>Protocol for listening to possible events that may occur in the <code>Provider</code>'s set of fonts.</p>
<p>Register a listener using <a class='link' href='../fuchsia.fonts/'>fuchsia.fonts</a>/<a class='link' href='../fuchsia.fonts/#Provider.RegisterFontSetEventListener'>Provider.RegisterFontSetEventListener</a>.</p>


### OnFontSetUpdated {#FontSetEventListener.OnFontSetUpdated}

<p>The set of fonts available in the <code>Provider</code> has changed. See
<a class='link' href='../fuchsia.fonts/'>fuchsia.fonts</a>/<a class='link' href='../fuchsia.fonts/#FontSetUpdatedEvent'>FontSetUpdatedEvent</a>.</p>



#### Request {#FontSetEventListener.OnFontSetUpdated_Request}

<table>
    <tr><th>Name</th><th>Type</th></tr>
        <tr>
            <td><code>event</code></td>
            <td>
                <code><a class='link' href='#FontSetUpdatedEvent'>FontSetUpdatedEvent</a></code>
            </td>
        </tr>
</table>


#### Response {#FontSetEventListener.OnFontSetUpdated_Response}

## Provider {#Provider}
*Defined in [fuchsia.fonts/font_provider.fidl](https://cs.opensource.google/fuchsia/fuchsia/+/main:sdk/fidl/fuchsia.fonts/font_provider.fidl;l=113)*
<p>Provider of digital font files and metadata.</p>
<p>TODO(fxbug.dev/8903): Remove deprecated methods and move to provider.fidl.</p>


### GetFamilyInfo {#Provider.GetFamilyInfo}

<p>Deprecated. See <code>GetFontFamilyInfo</code>.</p>
<p>Returns information for the specified font family or null if there is
no family with the specified name. This function respects family name
aliases and ignores case, so request for &quot;robotoSLAB&quot; will return
FamilyInfo for &quot;Roboto Slab&quot;.</p>



#### Request {#Provider.GetFamilyInfo_Request}

<table>
    <tr><th>Name</th><th>Type</th></tr>
        <tr>
            <td><code>family</code></td>
            <td>
                <code>string[128]</code>
            </td>
        </tr>
</table>


#### Response {#Provider.GetFamilyInfo_Response}

<table>
    <tr><th>Name</th><th>Type</th></tr>
        <tr>
            <td><code>family_info</code></td>
            <td>
                <code><a class='link' href='#FamilyInfo'>FamilyInfo</a>?</code>
            </td>
        </tr>
</table>

### GetFont {#Provider.GetFont}

<p>Deprecated. See <code>GetTypeface</code>.</p>
<p>Returns font that matches specified <code>request</code>.</p>



#### Request {#Provider.GetFont_Request}

<table>
    <tr><th>Name</th><th>Type</th></tr>
        <tr>
            <td><code>request</code></td>
            <td>

                <code><a class='link' href='#Response'>Response</a>?</code>
            </td>
        </tr>
</table>

### GetFontFamilyInfo {#Provider.GetFontFamilyInfo}

<p>Returns information for the specified font family, or an empty table if there is no family
with the specified name.</p>
<p>This function respects family name aliases and ignores case. For example, &quot;RobotoSlab&quot; is an
alias for the canonical name &quot;Roboto Slab&quot;. A request for &quot;robotoSLAB&quot; would return the
<code>FontFamilyInfo</code> for &quot;Roboto Slab&quot; due to the case-insensitivity and alias resolution.</p>

    <tr><th>Name</th><th>Type</th></tr>
        <tr>
            <td><code>family</code></td>

    <tr><th>Name</th><th>Type</th></tr>
        <tr>

                <code><a class='link' href='#FontFamilyInfo'>FontFamilyInfo</a></code>
            </td>
        </tr>
</table>

### GetTypeface {#Provider.GetTypeface}

<p>Returns a typeface that matches the specified <code>request</code>, or an empty table if no matching
face is found. (The latter is more likely to happen if <code>TypefaceRequestFlags.EXACT_FAMILY</code>
is used to disable fallbacks.)</p>



#### Request {#Provider.GetTypeface_Request}

<table>
    <tr><th>Name</th><th>Type</th></tr>
        <tr>
            <td><code>request</code></td>
            <td>

            </td>
        </tr>
</table>


#### Response {#Provider.GetTypeface_Response}

<table>
    <tr><th>Name</th><th>Type</th></tr>
        <tr>
            <td><code>response</code></td>
            <td>
                <code><a class='link' href='#TypefaceResponse'>TypefaceResponse</a></code>
            </td>
        </tr>
</table>

### RegisterFontSetEventListener {#Provider.RegisterFontSetEventListener}

<p>Register a listener to be notified when the set of available fonts or mappings has changed.
A client can register as many listeners as it wishes.</p>
<p>To unregister, close the channel.</p>



#### Request {#Provider.RegisterFontSetEventListener_Request}
