It seems that commit 17167 was not enough to ensure that the proper hide/show/update methods are called.

* 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.
