OnPartialUpdate (); clips load, clear?

Hello, is it possible to use multiple clips for the onPartialUpdate function?

I mean like this:

dc.setClip(x, y, width, height);
dc.setColor(Graphics.COLOR_TRANSPARENT, Graphics.COLOR_TRANSPARENT);
dc.fillRoundedRectangle(x, y, width, height, radius);

dc.clearClip();

dc.setClip(x, y, width, height);
dc.setColor(Graphics.COLOR_TRANSPARENT, Graphics.COLOR_TRANSPARENT);
dc.fillRoundedRectangle(x, y, width, height, radius);

dc.clearClip();

Or how can I load multiple objects but not at once?

I have already read the VS1hz- thread

Thank you

Yes it's very possible. I use onPartialUpdate() for both seconds and HR all the time. There are a few tricks, like have the two fields close to each other (row wise) as possible, and for efficiency, only do HR if it's changed.

I then do the dc,clearClip() at the beginning of onUpdate.

You'll note in the 1hz the example works that way. It doesn't ever do a clearClip in onPartialUpdate. With multiple clip regions, the get combined to do the actual draws. That's why you want fields close to reach other row-wise as when combined you don't want the entire screen to be impacted.

Thanks to Jim for answering.

What is the most effective way to draw a more clip, can you for me, but also for other users, which solves, or in the future I will solve a similar matter to give an example? I don't mean VS1hz ...

See https://forums.garmin.com/developer/connect-iq/f/discussion/7081/two-clips-on-1hz-watchface

in onPartial update, I do a dc.setClip for the seconds, update that, and if the HR has changed, do the dc.setClip() for that and update it.

Then at the beginning of onUpdate(), if the WF can do 1hz, I do the dc.clearClip();

And where can I find the source link and sample code?

Kook in this thread. It's a bit long but I've post an example a few times Check the very first post in it.
