General rules
|
|
-------------
|
|
|
|
Every editable field that affects the state of the dialog contents
|
|
from LyX's point of view should connect its xxxChanged() signal to
|
|
a the dialog's changed_adaptor() slot, which in turn should call
|
|
changed(). If you are using a more complicated thing anyway,
|
|
then remember to call changed() at the end (if it has changed!)
|
|
|
|
Every non-trivial widget should have a tooltip. If you don't know
|
|
what to write, write "FIXME", and it can fixed later. Don't be afraid
|
|
to use QWhatsThis too, but this must be done in the derived class's
|
|
constructor, and use _("..."). Non-trivial means that things like "OK"
|
|
/must not/ have a tooltip.
|
|
|
|
moc needs a fully qualified "std::string" for .connect() statements
|
|
to work. Be very, very careful.
|
|
|
|
Remember to check tab order on a dialog (third icon, with blue bars in
|
|
designer).
|
|
|
|
Remember to check sensible resizing behaviour on a dialog. This is
|
|
usually done by adding a top-level layout to the dialog in Designer.
|
|
|
|
Remember to use Edit->Check Accelerators
|
|
|
|
If necessary, you should override Qt2Base::isValid() for determining the
|
|
validity of the current dialog's contents.
|
|
|
|
OK/Apply/Restore/Close should be connected in the derived class's
|
|
constructor to call slotOK() etc. Refer to close/cancel as close in the
|
|
source.
|
|
|
|
Override update_contents() to update the dialog, not update(). Only
|
|
these functions may change dialog widgets that may emit changed() during
|
|
initialisation, to prevent the button controller from changing its
|
|
state.
|
|
|
|
Never call buttoncontroller functions directly from dialogs. In general,
|
|
you should use Qt2Base::changed() in all circumstances. However, if you
|
|
must call the buttoncontroller, make sure to respect Qt2Base::updating_
|
|
|
|
Naming conventions
|
|
------------------
|
|
|
|
QFoo.{cpp,h} The file that interacts with the controller _and_
|
|
the implementation of the dialog, derived from the generated files
|
|
ui/FooDialog.ui The designer file
|
|
ui_FooDialog.h Generated files from FooDialog.ui
|
|
|
|
slots should be named e.g. slotFooClicked(), slotFooSelected(), where
|
|
foo is the name of the widget.
|
|
|
|
Widgets should be named like "fooXX", where XX is one of the following
|
|
widget types :
|
|
|
|
CB - check box
|
|
CO - combo box
|
|
ED - line edit
|
|
GB - group box
|
|
LA - label
|
|
LC - LengthCombo
|
|
LV - QListView
|
|
ML - QTextBrowser
|
|
PB - push button
|
|
RB - radio button
|
|
SB - spin box
|
|
SL - slider
|
|
TE - text edit
|
|
TW - tree widget (FIXME: also TV in some files)
|
|
|
|
|
|
Qt, Unicode, and LyX
|
|
--------------------
|
|
|
|
LyX uses a different encoding (UCS4) than Qt (UTF16), therefore there are a
|
|
number of conversion functions in qt_helpers.{cpp,h}. Read the doxygen
|
|
documentation for details when to use which function.
|
|
|
|
Additionally, you should follow these simple rules :
|
|
|
|
o Use qt_() not _() in code
|
|
o Use the conversion functions of qt_helpers.h, NOT .latin1() / .c_str() etc.
