Solved How to connect button to function from other class?
-
Hi, what am I missing?
I don't know how to connect function from class Baza to QPushButton in .cpp ui file.
EncryptFile.hclass EncryptFile : public QMainWindow { Q_OBJECT public: EncryptFile(QWidget *parent = Q_NULLPTR); private: Ui::EncryptFileClass ui; private slots: void run(); };
Part EncryptFile.cpp
EncryptFile::EncryptFile(QWidget *parent) : QMainWindow(parent) { ui.setupUi(this); Baza *plik = new Baza(); connect(ui.createBtn, &QPushButton::clicked, this, &EncryptFile::run); connect(ui.bazaBtn, &QPushButton::clicked, this, &Baza::createDatabase); }
Baza.h
class Baza : public QMainWindow { Q_OBJECT private: sqlite3 *database; char *errMsg = 0; int rc; public: Baza(QWidget *parent = Q_NULLPTR) {}; ~Baza() {}; public slots: void createDatabase(); };
First connect works. But another connect spit out: E0304, C2664, C3867.
Any ideas? Thanks :)

Hi,
Because you are using "this" as target which does not contain the method since it's not the same classe.
On a side note, Qt has a SQL module so you don't have to use SQLite directly.
