TeXstudio scripts – internal viewer

Question

I need to make a macro script that would "press" Fit to Width button in the TeXstudio's internal viewer.

I found that viewer object is called pdfs[0], but, unfortunately, on the wiki page there are no list of methods of this object.

Answer 1

Searching a bit in the source code (see here), I found that pdfs object may be related to PDFDocument.

From here I also found a script involving the pdf viewer.

Then I've made several attempts and I've figured out the solution:

pdfs[0].widget().fitWidth();
