When the Scintilla component reaches its
isModifiedthread, the application has crashed. This was all happened after I had closed the app's window.What is the solution for this problem? Any help and comments would be greatly appreciate and thanks!
Thank you!

@JackMyson said in Developing QScintilla based application then crashes:
BrStormTextMainWindow::handleTabChanged(int)
I guess this is something you implemented? What are you doing there?
According to the stack trace a tab is removed (QTabBar::removeTab(int)) and then BrStormTextMainWindow::handleTabChanged(int) is called - I guess you are trying to access something already deleted.
