* QDialogView.h: - QDialogView::forms() now requires a QWidget instead of a QDialog. This will allow us to use DockWidget in the future. - QView class code simplification: implement inline instead of repeating in the same file. - QView::forms() now returns the real object. - QController class code simplification: implement inline instead of repeating in the same file. * QDocumentDialog::update(): renamed to updateParams() to avoid clash with QWidget::update() * QPrefsDialog::update(): renamed to updateRc() to avoid clash with QWidget::update() * QTexinfoDialog::update(): now public so that it can be used in QDialogView. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@17195 a592a061-630c-0410-9148-cb99ea01b6c8
