Hi,
Digging deeper into this issue, we found another way to temporarily fix
the problem with a change in QScintilla and not in Scintilla.
In qsciscintillabase.cpp, in the constructor of QsciScintillaBase, adding
SendScintilla(SCI_SETBUFFEREDDRAW, 0);
fixes the display problem by disabling the display buffering (which is
not a very good solution).
Just in case this might give ideas about where the problem might be (we
are trying to built a small examples reproducing the problem).
Best regards,
Gilles

Thanks for the hint which effectively corrected the problem (which
appears on rhel5).
With the proposed change in Editor.cpp, the margin color is red. We
changed that using the QScintilla function "setFoldMarginColors".
What is the interest of the first argument to "setFoldMarginColors" ?
It doesn't seem to have any visible impact.
Has this change to Editor.cpp been proposed for inclusion in the
Scintilla sources?
Best regards,
Gilles

I've encountered similar glitches on rhel3, as a work around I
changed Editor.cpp (don't know the precise line - approx 1490ish) so
that instead of calling "surface->FillRectangle(rcSelMargin,
*pixmapSelPattern);" it calls "surface->FillRectangle(rcSelMargin,
vs.foldmarginColour.allocated);" instead, when the margin mask is
SC_MASK_FOLDERS

Subject: [QScintilla] QScintilla folding display issue with Qt4 (did
notexist with Qt3)
Hi,
We are porting a cross-platform application from Qt3.3.8 to Qt4.4.3
which uses QScintilla 2.3.2.
A class of our application inherits QsciScintilla, and uses the
Folding functionality.
A problem has appeared in the Qt4 version of our application that
does not occur in the Qt3 version:
- the display of the folding margin is not correct (screenshot
attached) under Linux, while it is correct under Windows.
This display problem occurs even if there is no lexer.
We have tried updating to QScintilla 2.4 but the problem persists.
Any hints as to what might be causing this behavior?
Are there additional initialization steps that should be performed
for QScintilla with Qt4 that were not needed with Qt3?
