From wxWidgets master 81570ae070b35c9d52de47b1f14897f3ff1a66c7. include/wx/defs.h -- __w64 warning disable patch by comex brought forward. include/wx/msw/window.h -- added GetContentScaleFactor() which was not implemented on Windows but is necessary for wxBitmap scaling on Mac OS X so it needs to work to avoid #ifdef-ing the code. src/gtk/window.cpp -- Modified DoSetClientSize() to direct call wxWindowGTK::DoSetSize() instead of using public wxWindowBase::SetSize() which now prevents derived classes (like wxAuiToolbar) intercepting the call and breaking it. This matches Windows which does NOT need to call DoSetSize internally. End result is this fixes Dolphin's debug tools toolbars on Linux. src/osx/window_osx.cpp -- Same fix as for GTK since it has the same issue. src/msw/radiobox.cpp -- Hacked to fix display in HiDPI (was clipping off end of text). Updated CMakeLists for Linux and Mac OS X. Small code changes to Dolphin to fix debug error boxes, deprecation warnings, and retain previous UI behavior on Windows.

/*
|
|
This is a bit complicated, so let me explain it in details. All lines that
|
|
were read from the local file (the only one we will ever modify) are stored
|
|
in a (doubly) linked list. Our problem is to know at which position in this
|
|
list should we insert the new entries/subgroups. To solve it we keep three
|
|
variables for each group: m_pLine, m_pLastEntry and m_pLastGroup.
|
|
|
|
m_pLine points to the line containing "[group_name]"
|
|
m_pLastEntry points to the last entry of this group in the local file.
|
|
m_pLastGroup subgroup
|
|
|
|
Initially, they're NULL all three. When the group (an entry/subgroup) is read
|
|
from the local file, the corresponding variable is set. However, if the group
|
|
was read from the global file and then modified or created by the application
|
|
these variables are still NULL and we need to create the corresponding lines.
|
|
See the following functions (and comments preceding them) for the details of
|
|
how we do it.
|
|
|
|
Also, when our last entry/group are deleted we need to find the new last
|
|
element - the code in DeleteEntry/Subgroup does this by backtracking the list
|
|
of lines until it either founds an entry/subgroup (and this is the new last
|
|
element) or the m_pLine of the group, in which case there are no more entries
|
|
(or subgroups) left and m_pLast<element> becomes NULL.
|
|
|
|
NB: This last problem could be avoided for entries if we added new entries
|
|
immediately after m_pLine, but in this case the entries would appear
|
|
backwards in the config file (OTOH, it's not that important) and as we
|
|
would still need to do it for the subgroups the code wouldn't have been
|
|
significantly less complicated.
