Thread: SWT: How to return updated combo item after selectionlistener and save it to disk

Hello my SWT friends

I am confused with selectionlistener in Eclipse SWT.
I want to save the updated combo items after it has been selected.
But I cannot return value inside widgetSelected since it must be void.
Then where to set AquiferStr = the updated items after selectionlistener is threw such as combo.getItem(combo.getSelectionIndex())


//return changes items in combo2
int rowNum=2;
String[][]AquiferStr=new String[rowNum][rowNum];
for (int i = 0; i < rowNum; i++) {
//ERROR IN SAVE. Without widgetSelected CANNOT RETURN combo2.getItem(combo.getSelectionIndex())
AquiferStr[i][0] = combo2.getItem(i);
AquiferStr[i][1] = (String)combo2.getText();
//AquiferStr[i][1] = (String) combo2.getItem(combo.getSelectionIndex());
System.out.println("save int getItem"+combo2.getItem(i));
}
return AquiferStr;
}

I made my code based on this original snippet
Sample Combo : ComboSWT JFace EclipseJava

The snapshot looks like this

My code is also attached.

Many thanks!
