How to zoom in on white space symbols

Joseph M Cutcher III

I need the tiny black dots in this image (which are white space symbols) to be larger.

holding down Ctrl + Scroll only makes the text bigger. not the symbols.

One way to make this whitespace symbol bigger is to use a scripting language plugin
for example python script and use the funtion setWhitespaceSize from the editor object.
Python example

editor.setWhitespaceSize(4)  # 2 is the default

This function called from a bufferactivated callback could do what you want to have.

Hi Claudia, I’m confused by that final part of your response as the OP didn’t ask to do this differently for different files/types. For myself, I just .setWhitespaceSize() once in my startup.py and it works forevermore, globally…am I missing your point about this?

As @Scott-Sumner pointed out I’ve always had success just setting the white space size during initialization.

What I’ve done in the past is catch the SCN_ZOOMIN and SCN_ZOOMOUT notifications and use some simplistic mechanism to map the zoom value to an appropriate whitespace size so that it is changed dynamically.

Note though there is a bug in the version of Scintilla that Notepad++ uses which does not draw the white space exactly centered. This is really only noticeable if you set the whitespace large enough.

Thx for the hint and alternatives. Actually I thought it is a buffer setting but gave it a try
and have to confirm it isn’t. But it is a per editor attribute which means, we have to set
editor1 and editor2 from within startup.py

editor1.setWhitespaceSize(4)
editor2.setWhitespaceSize(4)
