Please test the accessibility of the QtCreator 11.0 user interface with screen readers (NVDA and JAWS for Microsoft Window).
While the individual UI controls are supported well by the screen reader, using NVDA and JAWS (Windows 10, QtCreator 11.0), I ran into the following problems in the source code editor:
1. The editor toolbar  at the top of the editor view unexpectedly interferes with the screen reader, causing it to stop reading text entered in the editor and instead speak the toolbar element such as the Symbols drop-down menu .  the text I type them appears in the edit field, but is not spoken by the screen reader.
2. In the edit field, the screen reader reads the last single closing brace three times.
