I need to display very large logs that uses HTML tags for marking different types of data.
Using QTextEdit and QTextBrowser really slows the application, especially on append operations. I would really like to keep the QTextEdit interface and abilities.
I've seen people that implemented their own flavor of TextEdit to improve performance, but I wandered if anyone solved this issue using "Qt" tools. I thought about using the Model/View framework to load data on demand but it is not quite what it was intended for I think.
Maybe subclassing QTextEdit and override some of its slots for scrolling...
If anyone encountered this issue and solved it, I would appreciate some tips.
Since your log is presumably tabular at some level, then the Model/View framework sounds like it could work for you. Perhaps you could try using a
QListView with QGraphicsTextItem, It has methods for setting/getting HTML:
You'll get some benefits and hassles from writing it that way, but you should certainly be able to finesse the insertions and append speed.
