static void setMessageOutputCreator(MESSAGE_OUTPUT_CREATOR f)
sets function that will be used to create message output
MessageType
message can be in plain text or in html format
virtual void setTitle(const QString &title)=0
set title for the messages
static QgsMessageOutput * createMessageOutput()
function that returns new class derived from QgsMessageOutput (don&#39;t forget to delete it then if show...
static void logMessage(const QString &message, const QString &tag=QString(), Qgis::MessageLevel level=Qgis::Warning)
add a message to the instance (and create it if necessary)
QgsMessageOutput *(* MESSAGE_OUTPUT_CREATOR)()
Default implementation of message output interface.
void setMessage(const QString &message, MessageType msgType) override
set message, it won&#39;t be displayed until
virtual void setMessage(const QString &message, MessageType msgType)=0
set message, it won&#39;t be displayed until
void setTitle(const QString &title) override
set title for the messages
void appendMessage(const QString &message) override
message to be appended to the current text
virtual void showMessage(bool blocking=true)=0
display the message to the user and deletes itself
