Need a interface for resize the canvas by the size of the documentElement.client size

[zhoumeina]

When the VM's VNC display is larger than the browser window we only can add scrollbars to the side of the screen. It would be much more user-friendly if we scaled the display to the window size so that the full desktop is always in view.Can we support it?

we need a interface to set the width and height of the RFB.

What exactly are you asking for? Scaling and re-sizing are different things.

A resize in this context would be triggered by the client, what is missing is support for the "ExtendedDesktopSize" encoding which is already present in the RFB protocol.
Support for this encoding is added in pull request #271 , I recently discovered a bug in that code which is why I have not merged it yet. You can always inspect my code in display.js and try to help me find what is wrong if you want.
#271 would not add a GUI option for this, if that is what you mean with "interface", but with the underlaying functionality there, GUI options would be simple.

Scaling would not require the actual VNC session to be resized, could be done entirely on the client side.

I ran into this as well where the JS resized browser window was smaller than needed and was displaying scroll bars. This probably isn't a long term solution but adding to fb_width and fb_height where conf.onFBResize is called in rfb.js allowed me to increase the resized display enough to not have scroll bars in the browser.
ex: conf.onFBResize(that, fb_width + 16, fb_height + 18);

Hello,

I am also facing the same issue where I want to set the dynamic width and height of the RFB but can't. By default it gets set to 800px by 480px. Did anyone find the solution?
