highlight error messages in gui and provide links to open files (bug #35619) * QTerminal.cc (handleCustomContextMenuReques): use method via selecting the message only in windows * Filter.cpp (Filter::HotSpot::type(), Filter::HotSpot::setType): make Type a type in Filter, not in HotSpot; (RegExpFilter::RegExpFilter) create a filter with the corresponding type instead of different filters for different types; (RegExpFilter::HotSpot::HotSpot): A found hot spot is created with the types of the filter that found that hot spot; (RegExpFilter::process): remove some old debug message, which were already commented out, call newHotSpot with type as new parameter; (RegExpFilter::newHotSpot, UrlFilter::newHotSpot): new parameter type; (UrlFilter::process): derive this method for UrlFilter, too, allowing to connect signals for opening files later on; (UrlFilter::HotSpot::HotSpot): no extra action here, get type from filter; (UrlFilter::HotSpot::urlType): add new url type; (UrlFilter::HotSpot::activate): depending on link type, open link as before or call method for opening the file mentioned in the link; (UrlFilter::ErrorLinkRegExp): const defined reg. expression for error link; (UrlFilter::UrlFilter): set reg. expression depending on type; (UrlFilter::HotSpot::actions): in a case of a file link, only prepare an open, but no copy action for the context menu; (UrlFilter::request_open_file): method emitting the signal to the main window for opening the desired file at desired line; * Filter.h: make Filter class inherit from QObject for using singals, move enum Type from HotSpot to Filter and add the types Error and ErrorLink, Filter and Filter::HotSpot ctors with type parameter, add file opening signal to RegExpFilter and FilterObject, add Q_OBJECT directives, add method to FilterObject returning the instance variable _urlObject, add new urlType ErrorLink, add own process method and open file slot to UrlFilter, FilterObject: open file slot only emitting open file singal * QUnixTerminalImpl.cpp (ctor): initialize instance variable _parent; (initialize): add new filters for errors and for links to related files, connect latters signal to the appropriate main windows slot; * QUnixTerminalImpl.h: add instance variable _parent for signal connections * TerminalView.cpp (paintFilters): underline Link and ErrorLink, draw rectangle with transparency for Error and LinkError; (mousePressEvent, mouseMoveEvent): treat Link and ErrorLink the same way
