Hi all,
I have a QSyntaxHighlighter that applies not just coloring/formatting, but
also left/top margin, and text indent to the text to display it. It works
great. But the changes to the margin/indent are made via QTextCursor, and
they go onto the Undo stack, so it breaks undo/redo for the QTextEdit.
Does anyone have any idea of how I can change the margin/indent of a
QTextBlock without affecting the undo stack? I want the margins/indent to
be displayed but not viewed as changes to the underlying QTextDocument.
I'd rather not have to roll my own undo/redo...
//code in void QSyntaxHighlighter::highlightBlock(const QString &txt)
//determine level of text
if(level)
{
setCurrentBlockState(level);
blkfmt.setTopMargin(10);
blkfmt.setLeftMargin(((level)*2)*chW);
blkfmt.setTextIndent((-level-1)*chW);
myCur.mergeBlockFormat(blkfmt);
}
TIA,
Josh
