All .fd files go in this directory.
|
||
|
|
Each .fd file should have just one form in them
|
||
|
|
|
||
|
|
NOTE: An exception to the above is any tabbed form which
|
||
|
|
xforms requires multiple forms to create. In that case
|
||
|
|
the group of forms constitutes one gui form.
|
||
|
|
|
||
|
|
All forms should be named form_xxx and saved into a file by the same name.
|
||
|
|
For example, the copyright notice is called form_copyright and is stored in
|
||
|
|
form_copyright.fd. Its used by class FormCopyright. If you match this pattern
|
||
|
|
the fdfix.sh script will do nearly all the conversions for you. That'll make
|
||
|
|
updating the source incredibly easy.
|
||
|
|
|
||
|
|
Name all buttons and other form components that are likely to cause a callback.
|
||
|
|
The names should be of the form: button_ok, radio_group_item and so on.
|
||
|
|
|
||
|
|
Enter the full name of the callback eg.:
|
||
|
|
C_FormCopyrightOkCB
|
||
|
|
|
||
|
|
That is, they all have the same format: C_##FormName##CallbackName.
|
||
|
|
Your code will then need to use the appropriate macro to setup this C callback
|
||
|
|
function which will in turn call the corresponding static class member function
|
||
|
|
of the form FormName::CallbackName. You should be able to copy the macro
|
||
|
|
entries from a similar dialog for reuse without having to change anything.
|
||
|
|
|
||
|
|
The name of the wrapped dialog will be dialog_ eg.
|
||
|
|
typedef struct {
|
||
|
|
...
|
||
|
|
} FD_form_copyright;
|
||
|
|
|
||
|
|
FD_form_copyright * dialog_;
|
||
|
|
|
||
|
|
If you follow these simple rules then the generated code for create_form can
|
||
|
|
be directly used as the FormXxxx::build method without any extra editting to
|
||
|
|
make it work. Every forms implementation will follow a very simple pattern
|
||
|
|
and make it easier to maintain.
|
||
|
|
|
||
|
|
The easiest way to fit into this pattern is to copy an existing dialogs
|
||
|
|
implementation and adjust it to suit keeping the variable names the same.
|
||
|
|
In addition a lot of work can be saved by using the code that has already been
|
||
|
|
written in the "lyx" module of the LyX CVS repository. This is where the old
|
||
|
|
development branch is kept. The code there will need to be modified slightly
|
||
|
|
to meet these new guidelines. In addition, an earlier generation signalling
|
||
|
|
system was used in that code. A conversion script called gtmmconvert2 is
|
||
|
|
available from the gtk-- distribution. It updates all the signals to use
|
||
|
|
libsigc++.
|
||
|
|
|
||
|
|
Don't reinvent the wheel. There's 18 months worth of code in the "lyx"
|
||
|
|
module that you should at least use as a guide even if you don't actually make
|
||
|
|
direct use of it.
