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 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_;
|
|
|
|
Angus Leeming has modified the scripts to forward declare FD_form_xxxx thereby
|
|
removing one inter-file dependency and removing the struct declaration from the
|
|
FormXxxx.h file which was the previous practice.
|
|
|
|
If you follow these simple rules then the generated code for create_form_form_xxxx
|
|
can will be converted as the FormXxxx::build_xxxx method without any extra
|
|
editting to make it work. Every forms implementation will thereby follow a very
|
|
simple pattern and make it easier to maintain.
|
|
|
|
All the forms are rebuild by running `make updatesrc`. This will generate all
|
|
the form_xxxx.[Ch] files. You should run `make install` to install them in the
|
|
parent directory. `make install` will also regenerate all the files for you
|
|
so you don't have to do the `make updatesrc` step unless, for example, you are
|
|
testing the conversion scripts. The fdfix.sh, fdfixh.sed and makefile contain
|
|
the necessary smarts to convert the generated code into something that can be
|
|
used directly in the LyX codebase..
|
|
|
|
The easiest way to fit into the pattern is to copy an existing dialogs
|
|
implementation and adjust it to suit, keeping the variable names the same.
|
|
Take a look at the existing .fd files as well to see what is needed in there
|
|
in the way of callback names and widget names.
|
|
|
|
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 gtkmmconvert2 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" cvs
|
|
module that you should at least use as a guide even if you don't actually make
|
|
direct use of it.
