Summary: EM_SETEDITSTYLE Does not work Product: Wine Version: unspecified Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: richedit AssignedTo: wine-bugs@winehq.org ReportedBy: mark@thermeon.com
This is part of the richedit controls is that in Windows, richedit controls have the ability to emulate a regular edit control and it gives the ability to have unicode edit boxes on non-unicode systems (win9x). By emulating a regular editor control, richedit can (among other things) allow a tab to switch away from the control rather than entering the tab into the edited text (like notepad or wordpad)
The part needed is to support the EM_SETEDITSTYLE message, specifically the SES_EMULATESYSEDIT parameter. The description in the windows docs is:
"When this bit is on, rich edit attempts to emulate the system edit control"
Thanks
