[Bug 44680] New: Support for DTM_GETIDEALSIZE not implemented

https://bugs.winehq.org/show_bug.cgi?id=44680

Bug ID: 44680
           Summary: Support for DTM_GETIDEALSIZE not implemented
           Product: Wine
           Version: 3.0
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: comctl32
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

When "Windows Version" is set to "Vista" or later, date picker controls in
programs written using wxWidgets disappear because wxWidgets assumes that
DTM_GETIDEALSIZE is available in these Windows versions (see
https://github.com/wxWidgets/wxWidgets/blob/v3.1.1/src/msw/datetimectrl.cpp#...),
but it isn't in Wine, so we just get "err:datetime:DATETIME_WindowProc unknown
msg 100f" on the console and the control is created with 0 size.

We could work around this in wx but, ideally, Wine should handle this message.
Even returning some hard coded size from it would be better than not handling
it at all.

Hi,

hardcoded value won't be an option, we'll want something closer to proper
behaviour. However what you can do from your side to make it more robust, is to
check if DTM_GETIDEALSIZE actually works, and not rely on reported Windows
version. According to MSDN return value of 1 is expected for this message,
while on Wine (or XP) you probably get 0. That doesn't mean we won't fix it of
course, but that could be a solution until we do that.

Yes, indeed, I did just this in
https://github.com/wxWidgets/wxWidgets/commit/66fdf49 for now, I'm mostly
reporting this because it could affect other programs as well.
