Rules for the use of popups
|
|
===========================
|
|
|
|
We need to have some rules in order to keep LyX enjoyable to use. This
|
|
document describes the rules for designing popups. Please obey the rules.
|
|
If you don't do it correctly, somebody else has to fix it for you, and we
|
|
don't like to waste time because you were lazy. So, read it now, design
|
|
your popups, and come back and check if your new popup is in compliance.
|
|
|
|
Internationalization
|
|
--------------------
|
|
|
|
We need some rules to be followed so that popups and short-cuts will
|
|
work properly with regard to internationalization and gettext.
|
|
|
|
We have made a method to make the shortcuts in xforms work correctly with
|
|
internationalizationed shortcuts. We concat the label and the shortcut like
|
|
this:
|
|
|
|
<ident>|<shortcut> (where <ident> often is a label)
|
|
|
|
And have made two funcs to extract that info: scex and idex
|
|
(shortcut-extract and ident-extract). To minimize the translation effort
|
|
you should use stuff like:
|
|
|
|
fl_add_object(<params>, idex(_("<ident>|<shortcut>")));
|
|
fl_set_shortcut(<obj>, scex(_("<ident>|<shortcut>")));
|
|
|
|
Make sure the two texts are identical, such that gettext will join them.
|
|
|
|
This will also help use make the labels and shortcuts consistent across
|
|
all the dialogs.
|
|
|
|
Some <ident>|<shortcuts> pairs have been decided:
|
|
|
|
1. Most popups have at least three buttons in common:
|
|
|
|
- OK No shortcut in the usual case (it is a return button)
|
|
- Apply "Apply|#A"
|
|
- Cancel "Cancel|^[" (This is the escape key)
|
|
You can optionally use "Cancel|#C^[" also.
|
|
- Close Either return-button, "Close|^[" or "Close|#C^[".
|
|
|
|
Design rules
|
|
------------
|
|
|
|
1) Remember that you have to add this function to your form definition:
|
|
|
|
fl_set_form_atclose(form, CancelCloseBoxCB, NULL);
|
|
|
|
to prevent crashes when the users close the popup with the window manager.
|
|
You need to #include "lyx_gui_misc.h" to get CancelCloseBoxCB.
|
|
|
|
More will follow...
|
|
|
|
NB! If any of the shortcut keys is a part of the label and you want it to
|
|
be underlined in the label, that character must be the _first_ in the
|
|
accelerator string (allthough it may be an alt-key etc). Case _sensitive_.
|
|
Apply|Pp#p#P won't get an underlined 'p'
|
|
Apply|GpaAP won't either.
|
|
Apply|aA nope
|
|
Apply|pP#p#P will underline the first 'p'
|
|
Apply|Aa will underline the 'A'
|
|
Apply|#Aa will also underline the 'A'!
|
|
See the docs for xforms... (fl_set_shortcut() etc)
|
|
It seems xforms .86 doesn't recognise 128+ chars as shortcuts. (not with
|
|
fl_set_shortcut() anyway) /Joacim
