Hello together,
Im new to this mailing list and tried to find out if this question
already has been posted. I didnt find anything, so please apologize
if
Im wrong.
We use QScintilla for a Python script editor and mark some lines with
a background marker with a different background color (e.g. red). If
this color does not have an alpha component, everything is fine.
However, if there is an alpha component, the rectangular background
has a black margin, which is not desired, especially if the line
below
or above has the same background color.
I tried to find out where this fact comes from. The alpha-version of
the marker uses SurfaceImpl::AlphaRectangle in PlatQt.cpp. This
function modifies the brush of the QPainter, however not the pen. In
the non-alpha version (RoundedRectangle), the pen is modified and in
many other functions the pen is explicitely set to NoPen before
drawing. By not setting set pen, the last configuration is used,
depending on which function is called before.
If the pen would have been set to NoPen in AlphaRectangle, no border
should be painted.
Is the border-behaviour desired for the alpha version? Else, maybe my
suggestion would help to solve this.
If you add the following line before the call to drawRoundRect()...
painter->setPen(convertQColor(outline, alphaOutline));
...does it behave as you want?
