Thunderbird just messed up the indentation.
Sorry.

Hi guys,
I have a PyQt4 application with a QScintilla2 editor with Python3
and the following function:
def create_hotspot(node_tab):
#Create the hotspot boundaries
hotspot_line = node_tab.lines()-2
hotspot_first_ch =
node_tab.text(hotspot_line).index("-")
hotspot_length = node_tab.lineLength(hotspot_line)
hotspot_start =
node_tab.positionFromLineIndex(hotspot_line, hotspot_first_ch)
hotspot_end =
node_tab.positionFromLineIndex(hotspot_line, hotspot_length)
#Style the hotspot
node_tab.SendScintilla(PyQt4.Qsci.QsciScintillaBase.SCI_STYLESETHOTSPOT,
2, True)
node_tab.SendScintilla(PyQt4.Qsci.QsciScintillaBase.SCI_SETHOTSPOTACTIVEFORE,
True, 0xff0000)
node_tab.SendScintilla(PyQt4.Qsci.QsciScintillaBase.SCI_SETHOTSPOTACTIVEUNDERLINE,
True)
node_tab.SendScintilla(PyQt4.Qsci.QsciScintillaBase.SCI_STARTSTYLING, hotspot_start,
31)
node_tab.SendScintilla(PyQt4.Qsci.QsciScintillaBase.SCI_SETSTYLING,
hotspot_end, 2) <- ERROR
On Windows this works great, but on Ubuntu this gives me the error
at the last line with the message:
Assertion [lengthStyle == 0 || (lengthStyle > 0 && lengthStyle +
position <= style.Length())]
failed at ../src/CellBuffer.cpp 426
I'd need a short complete example that demonstrates the problem.
However a better solution would be to add a decent hotspot API so you
wouldn't need to fiddle with things like this. Do you want to propose
such an API?

Hi Phil,
Just figured out that when calling SendScintilla with SCI_SETSTYLING, I
used indexes that went out of the document scope.
That doesn't seem to raise an error on Windows, only on Linux.
As for the hotspot API, I think something like the indicators use would
be the best and the most consistent.
Scintilla uses only a single hotspot, so if adding multiple styles is
not an option, scratch that idea.
Setting up a hotspot style:
int setHotspotForeColor(QColor color, int hotspotNumber)
QColor hotspotForeColor(int hotspotNumber)
int sethotspotForeColorEnabled(bool useForegroundColor, int
hotspotNumber)
bool hotspotForeColorEnabled(int hotspotNumber)
int setHotspotBackColor(bool useBackgroundColor, QColor
color, int hotspotNumber)
QColor hotspotBackColor(int hotspotNumber)
int sethotspotBackColorEnabled(bool useBackgroundColor, int
hotspotNumber)
bool hotspotBackColorEnabled(int hotspotNumber)
int setHotspotUnderline(bool underline, int hotspotNumber)
bool hotspotUnderline(int hotspotNumber)
int setHotspotSingleLine(bool singleLine, int hotspotNumber)
bool hotspotSingleLine(int hotspotNumber)
Styling with a hotspot:
fillHotspotRange(int lineFrom, int indexFrom, int lineTo, int
indexTo, int hotspotNumber)
clearHotspotRange(int lineFrom, int indexFrom, int lineTo, int
indexTo, int hotspotNumber)
I hope I understood you correctly about the API proposal.
Matic
