[bt-devel] Run Into A Problem With Bibletime

[Joachim Ansorg]

Hi!

Connecting signals to slots or signals is only possible with valid objects.
If you want to connect signal signal1 to the slot slot1 of the m1 member of  
the class1 you have to write this:

object1 = new class1;
connect(this, SIGNAL(signal1()), object1->m1, SLOT(slot1()));

Connecting to w_book of CBibleKeyChooser is not possible, because it's not a 
member of an object in this context (CBibleKeyChooser::w_book is only valid 
for a static w_book member of CBibleKeyChooser).

If you have a look at the function CBiblePresenter::refresh you see how 
changes made in the optionsdialog are processed.
We use an enum of CSwordPresenter which holds the possible changes. erefresh 
checks if the value is set and refreshes the members accordingly to this.

I'd suggest that you add the correct values to the enums in CSwordPresenter, 
that you add processing of them in the C*Presenter classes and that you set 
the values in the right function  COptionsDialog (havbe a loom into the 
COptionsDialog::save* functions how to set the values).

I'm glad that you are still working with us. Many people have given up after 
a short time. I know it's difficult in the beginning but it's really much 
more easy later.
