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
|
|
form_->changed(). If you are using a more complicated thing anyway,
|
|
then remember to call form_->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.
|
|
|
|
*DO NOT USE DESIGNER FROM Qt 3*. You must use a designer from Qt 2 to
|
|
maintain compatibility.
|
|
|
|
Remember to check tab order on a dialog (third icon, with blue bars in designer).
|
|
|
|
Remember to check sensible resizing behaviour on a dialog.
|
|
|
|
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 form_->slotOK() etc. Refer to close/cancel as close in the source.
|
|
|
|
Override update_contents() to update the dialog, not update(), and build_dialog(),
|
|
not build(). 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_
|
|
|
|
Don't #undef emit - #include "QtLyXView.h" instead
|
|
|
|
Naming conventions
|
|
------------------
|
|
|
|
QFoo.[Ch] The file that interacts with the controller
|
|
QFooDialog.[Ch] The implementation of the dialog, derived from the generated files
|
|
ui/QFooDialog.ui The designer file
|
|
ui/QFooDialogBase.[Ch] Generated files from QFooDialog.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
|
|
LA - label
|
|
ML -
|
|
PB - push button
|
|
(FIXME: complete this)
|
|
|
|
|
|
Stuff to be aware of
|
|
--------------------
|
|
|
|
The connect statement in Qt is a macro and its arguments does not follow
|
|
the C++ standard as it should. Using the construct "Type const &" as
|
|
argument will lead to runtime-errors, use "const Type &" instead.
|
|
|
|
ex.
|
|
|
|
--right--
|
|
|
|
connect(list, SIGNAL(selected(const QString &)),
|
|
this, SLOT(complete_selected(const QString &)));
|
|
|
|
--wrong--
|
|
|
|
connect(list, SIGNAL(selected(QString const &)),
|
|
this, SLOT(complete_selected(QString const &)));
|
|
|
|
Qt, Unicode, and LyX
|
|
--------------------
|
|
|
|
LyX isn't unicoded yet. But you should follow these simple rules :
|
|
|
|
o Use qt_() not _() in code
|
|
o Use fromqstr and toqstr NOT .latin1() / .c_str()
|
|
|
|
Using these functions (in qt_helpers.h) will make sure we use
|
|
the right locale for converting to Qt's QString, which is unicode.
