Subject: [PATCH 15/16] Use the state of the key event to process it
|
||
|
||
Use the state of the key event instead of the global state.
|
||
UpdateXKBStateFromState uses xkbModMask, which needs updateXKBMods
|
||
to be called beforehand.
|
||
|
||
Task-number: QTBUG-48795
|
||
Change-Id: Ic2c545718adb68df41730e5a3bf25adb374ffce3
