Home view activity start-new using Alt key does not work about sugar HOT 5 CLOSED

@Pro-Panda, there was an e-mail to me from GitHub saying you would like to work on this, but the comment is missing from this issue. Is this a regression of GitHub, or did you delete? If you deleted, was there something ambiguous about the issue that needs more details?

@quozl
I deleted and forgot to write the updated one. Sorry
So this was what I found:

• alt+click is not handled by any layer of button-press-event or any other signal in Sugar. Hence this

Observed result; no response, no errors logged.

• It then goes to the underlying OS(on Ubuntu 16.04) and is used to move the window(rdesktop) by dragging the mouse
• II am trying to override it in the same way as Alt+Tab is done.

Do you think I might be on the correct lines ?

from sugar.

No, wrong lines altogether. HomeWindow.__key_press_event_cb is where the alt key press is detected, and it saves state using set_resume_mode; a method of HomeBox.

@quozl Sorry, my previous statement might be ambiguous.
This is what I found.
While reproducing the issue,

1. Press alt: detected by HomeWindow.__key_press_event_cb
2. Keep holding alt
3. Clicking on any button after that; button-press-event is not detected by any layer of widgets via any signal
4. Release alt: detected by HomeWindow.__key_release_event_cb

Proposed Reason - Mouse cursor changes during 3 to one of dragging the window(rdesktop), as thats a feature of Ubuntu provided for any window
Supporting Statement - I couldn't reproduce this issue when I log into Sugar Desktop Environment instead of Ubuntu Desktop Environment at the login page of ubuntu. It creates a new activity in that case.

Thanks for the investigation. I agree. For me, symptom only occurs on VM (virt-manager, VirtualBox) under wmaker, and there is no change of cursor image, but the virtual machine window can be dragged.

Symptom does not occur on native hardware.
