Jambi - Eclipse - Designer - Slots

[ronnyf]

Hi folks,

I recently started (again) playing around with Qt (last time was 3.3 I guess). And I have come across an issue I would like to confirm with you.
This is what I did initially:

• Create a Qt Jambi Project in Eclipse (3.4)
• Create a Qt Jambi Design Form (MainWindow)
• Created a simple UI (with Eclipse Designer Interface)

Now I understand that I need to connect the button (pushButton_add) to a slot. This is where I am facing the issue. I do not seem to be able to do so.

After a bit of googling I tried to hard code the connection in the TestMain.java file that has been generated buy the designer (TestJava.jui). The problem is now, when I change my UI, the Designer generates a new TestMain.java, overwriting my edits (inconvenient to say the least!). I am now required to rely on TestMainImpl.java for slot definition?

public class TestMainImpl extends QMainWindow {
TestMain ui = new TestMain();
 
public static void main (String[] args) {
...initialize();
...
...exec();
}
 
public TestMain() {
ui.setupUi(this);
//is this the right place for that?!?!?!?!
ui.pushbutton_add.clicked.connect(this, "pushButton_add_clicked()");
}

public class TestMainImpl extends QMainWindow {
TestMain ui = new TestMain();

public static void main (String[] args) {
...initialize();
...
...exec();
}

public TestMain() {
ui.setupUi(this);
//is this the right place for that?!?!?!?!
ui.pushbutton_add.clicked.connect(this, "pushButton_add_clicked()");
}

To copy to clipboard, switch view to plain text mode 

That is sad but ok, if it has to be like this, I can deal with it. What is the Signal/Slot editor for then anyways? Am I doing something wrong; did I misunderstand a concept? Please help me out here, your help is greatly appreciated.

Good day

Ronny

You have to derive a class from TestMain and add all the code you need there. The other way is to use aggregation instead of inheritance.

Yes, you are absolutely right. More intensive reading would have solved my issue by itself.
Thanks for your help.
