Loading Screen Delay

Hello,

Need some advice, I have a Welcome screen and I have background image linked to a sharepoint image library. Also, on that screen I have some components like buttons etc

In the onstart, I have set the backround image to pick a random image from the collection -

Set(varbackgroundimages,'Background Images');
ClearCollect(colBackgroundImages,ShowColumns(varbackgroundimages,Image));
Set(varRandomBackgroundImage,First(Shuffle(colBackgroundImages)).Image0.Full);
 
 
All works fine expect the components load faster than the image so I though about adding a timer or spinner and then also tried a new screen with a timer and loading image and on timer end, navigate to the welcome screen but even then its still slightly slow, any ideas to get the components and background image to load at the same time?
 
Thanks
 
Ross

Hi @rosscortb

1. Is your OnStart set to Async?

2. Move stuff to OnVisible

3. My real Suggestion is to create an Overlay that is over the ENTIRE screen it makes it so you cannot see the back ground/controls until after its actually Visible.

Think of it like, you need to load lots of data, but the controls are showing... but they are empty and then bingo 25 seconds later data appears. its terrible.

So give your screen time to really load, then remove the cover image.

Problem and experience solved.

@rosscortb Please try this:

Set the Visible property of all the components to varIsVisible

Update the OnStart property of the app to:

Set(varIsVisible,false); Set(varbackgroundimages,'Background Images'); ClearCollect(colBackgroundImages,ShowColumns(varbackgroundimages,Image)); Set(varRandomBackgroundImage,First(Shuffle(colBackgroundImages)).Image0.Full); Set(varIsVisible, true);

Alternatively, instead of messing with Visible property of all controls, you can place a spinner control to cover the whole screen.
Set its Visible property to varIsVisible, and change to OnStart property of the app to:

Set(varIsVisible,true); Set(varbackgroundimages,'Background Images'); ClearCollect(colBackgroundImages,ShowColumns(varbackgroundimages,Image)); Set(varRandomBackgroundImage,First(Shuffle(colBackgroundImages)).Image0.Full); Set(varIsVisible,false);
