Hello,

Because pdfjs does not support themes, one possible solution, you need to change viewer.css ( for example in a folder \FMSoft\Framework\uniGUI\uni-1.70.0.14xx\pdf.js\web )

Just add the following css rules at the end, and don't forget to clear your browser's cache:

#viewer, #toolbarViewer {
    background-color: green !important
}        

.toolbarButton, .secondaryToolbarButton, .overlayButton {
   	background-color: orange !important;
}

Hello,

- Which theme are you using?
- Which versions of uniGUI?
- Could you provide a minimal test case?

Yes, it's enough for me not even to change the color, but just to take and hide the entire panel with controls completely.
To just display the PDF document and that's it, and you could just view it.

Is it possible to do this in principle?
