CEF Forum

Hi,

Is there any command line arguement to hide sidebar in PDF?

This was not coming in cefsharp v86 client, but when i tested this on cefsharp v92 client, it started appearing.

I have attached pdf preview for v92 client & one from Edge browser which is same as v86 client behavior.

Please note in standalone chrome browser (92.0.4515.159), we do see the sidebar but not in edge chromium browser(92.0.902.78 ).

Sample PDF to test :
https://www.w3.org/WAI/ER/tests/xhtml/t ... /dummy.pdf

There must be some setting to hide this, but i am not able find this.

Have you searched for ways to disable the sidebar in Chrome? Find out if chrome supports disabling the sidebar then see if the same works in CEF.

Without looking on the code I have noticed a some code place that might be interesting:

\chromium\src\chrome\browser\resources\pdf\elements\viewer-pdf-toolbar.html, cr-icon-button id="print"

This is the representation of the PDF Viewer in HTML and the cr-icon-button="print" is the print button on the upper right.
Maybe the sidebar is in there too and you can comment it out or find a switch that influences it?

One update:

It seems to be an issue from chromium side to hide navigationpane (i.e. side bar).

ex :
https://www.w3.org/WAI/ER/tests/xhtml/t ... navpanes=0

Adding #values in url like #Navpanes=0&toolbar=0, hides both toolbar and sidebar, specifying one of them does not seems to be working and can see a open bugs on chromium side.
