c++ - Qt Whenever pressed enter in QTextEdit -

whenever pressed enter in qtextedit it'll perform click on login button. somehow causes crash of qtcreator. how can change what'll happen if press enter in qtextedit?

you need subclass qtextedit , catch event you're interested in overriding appropriate method:

class mytextedit : public qtextedit {     q_object public:     void mytextedit::keypressevent(qkeyevent *event)     {         if (event->key() == qt::key_return)         {             login(); // or rather emit submitted() or along way         }         else         {             qtextedit::keypressevent(event);         }     } }; 

alternatively, can install event filter on text edit.
