Description David REVOY 2012-06-29 18:07:45 UTC

Here are 2 feedback I wrote on the mailing list thread "Merged the first bits of Canvas Interaction" (06/26/2012 04:21 PM). I duplicate them here to make it easier to maintain. 

1/ zoom origin
Zooming is always centered to the viewport, could it be centered in the cursor/mouse position ( the start position when the dragging action is performed ) ?
( ex: I start to press Ctrl+Space on keyboard ; I move my cursor hover top left , and click to zoom = the zoom is focusing on this zone )

2/ switch from 'Ctrl-space zoom' to 'space pan' and vice versa.
When pressing Ctrl+Space+click to zoom, if I keep space hold and release Ctrl it's not switch to panning , and the zoom continue. I would love to can do it.
Same for reverse : While panning with space pressed, I would love to only add control to switch to zooming. 

Reproducible: Always

Actual Results:

Ack...

Comment 2 Halla Rempt 2012-08-08 19:20:00 UTC

marking as regression.

Comment 3 Dmitry Kazakov 2012-11-11 09:00:41 UTC

The same bug happens when you try to Rotate a canvas: pressing Shift allows to rotate it only once. After you release Middle Button, you need to press shift one more time.

Comment 4 Dmitry Kazakov 2012-11-11 10:15:06 UTC

Pressing Ctrl, then holding '+' or '-' keys enables Keys Autorepeat that has to be disabled.

Fixed the second half of bug 302758

This patch almost rewrites the KisInputManager to fix the mentioned
bug. Now all the state transitions of the actions are controlled by
a special class KisShorcutMatcher. This class is easily controlled by
a separate unittest. The work of the actions is now can be represented
by a simple state machine with three states (see docs for class
KisStrokeShortcut).
