  I am automating test cases using the Python RTA framework with Citrix as my VDI, which runs in the browser due to a screen resolution issue. The testing machine is accessed remotely through TigerVNC Viewer, with PyCharm running on Windows and VNC on Linux. While performing certain key combinations like Alt + other function keys, they work as expected. However, when using Alt + Tab, it switches between applications instead of invoking the desired popup on the test machine. I need to pass this key combination directly to the test machine in order to trigger the popup.

Have to pass alt+tab

Hemachandar Aravamuthan <hemach...@gmail.com>: Mar 16 06:52PM -0700 I'm using Citrix in a browser, and within it, I have TigerVNC Viewer. During automation, I need to pass Alt+Tab to perform an action in my testing software, but it's causing tab switching instead.

That would be a question for a Citrix forum and not here.   Regards, -- Pierre Ossman Software Development Cendio AB http://cendio.com Teknikringen 8 http://twitter.com/ThinLinc 583 30 Linköping http://facebook.com/ThinLinc Phone: +46-13-214600   A: Because it messes up the order in which people normally read text.

In what way have you made sure it passes all the way through to the TigerVNC viewer?   Regards, -- Pierre Ossman Software Development Cendio AB https://cendio.com Teknikringen 8 https://twitter.com/ThinLinc 583 30 Linköping https://facebook.com/ThinLinc Phone: +46-13-214600   A: Because it messes up the order in which people normally read text.

Hemachandar Aravamuthan <hemach...@gmail.com>: Mar 17 02:19PM +0530 All other commands are functioning properly in the vncviewer, however, the Alt+Tab shortcut is switching between applications. I am using TigerVNC version 1.10.80. Could you kindly confirm if there is any issue with this version?

What is crashing? Where is TigerVNC involved here, and how is it set up?   Regards, -- Pierre Ossman Software Development Cendio AB http://cendio.com Teknikringen 8 http://twitter.com/ThinLinc 583 30 Linköping http://facebook.com/ThinLinc Phone: +46-13-214600   A: Because it messes up the order in which people normally read text.
