Try this instead:
package default;
import com.trolltech.qt.gui.*;
public class Program extends QMainWindow { //here eclipse has used
QWidget, but it reported a errror
Ui_Program ui = new Ui_Program();
public static void main(String[] args) {
QApplication.initialize(args);
Program testProgram = new Program();
testProgram.show();
QApplication.exec();
}
public void initSignals(){
ui.IniciarBuscaButton.clicked.connect(this, "myFunc()");
}
public Program() {
ui.setupUi(this);
initSignals();
}
public void myFunc() {
System.out.println("My slot is called!");
}
}
There were a few things wrong in your code:
1. You cannot declare slots, nor write any kind of code in the Ui_Xxx
files as these are generated from the .jui files and all changes made
will be overwritten. This is also indicated by the headercomment in the
file. Above I implemented myFunc() in the Program class instead.
2. When you connect a signal to a slot, you spesify who is the receiver
of the signal and which function in that instance to call. You passed
QApplication.instance(), which does not implement a function "myFunc()".
Since its the Program class that implements the "myFunc()", you need to
pass the program instance.
