Restarting Stream Deck app or computer removes button image and text

[Muhomorik]

Hello,

I have a problem that when I set image and text with code, values disappear when I restart the app or computer (ofc).
I can seen the icon and text while computer powers off and until SD app has loaded.
Then it resets to icon in the manifest.

PI

    <div class="sdpi-item">
         <div class="sdpi-item-label">setImage</div>
         <button class="sdpi-item-value" id="btn_setImage" onclick="testSetImage()">Sent image</button>
    </div>

    const imgGreen = 'data:image/png;base64,...'
    const imgRed= 'data:image/png;base64,...'
    
    let imgIndex = 0;
    
    function testSetImage(clickedTab) {
        console.log('testSetGlobals');
    
        let currImage = '';
        if (imgIndex === 0){
            imgIndex = 1;
            currImage = imgGreen;
        } else {
            imgIndex = 0;
            currImage = imgRed;
        }
    
        $PI.sendToPlugin({
            cmd: 'image',
            payload: currImage
        })
    }

Plugin (app.js)

    $SD.on(`com.iccms.dmitri-1.action-test-1.sendToPlugin`, (jsn) => {
        console.log('Main, sendToPlugin')

        if (jsn.payload.cmd ==='image'){
            $SD.setImage(jsn.context, jsn.payload.payload);
        }
    });

Do I need to handle icon and text, set by code somehow at launch? In that case in which event?
I would expect it to be saved and restored.

Hi @Muhomorik,

That is correct, user set icons and titles are retained on restart, but icons and titles provided by the plugin will need to be set again. There are a few events that can help with this: willAppear on the action (this is typically where I handle drawing things) or systemDidWakeUp from Stream Deck.

https://docs.elgato.com/sdk/plugins/events-received#willappear
https://docs.elgato.com/sdk/plugins/events-received#systemdidwakeup

The SDK also provides a connected event that is sent when the plugin opens the websocket connection to Stream Deck.

All of these could work to help keep the key icon and title up to date.
