Member Function Documentation

addModeSnapback()

void smtk::extension::qtDiagramView::addModeSnapback	(	Qt::Key	snapBackOnReleaseKey,
		smtk::string::Token	snapToMode
	)

Temporarily change modes until snapBackOnReleaseKey is released.

When qtDiagramViewMode classes capture key presses (and only presses, not releases) in order to use modifier keys to switch modes temporarily, they can call this method on the view and, when the key is released by the user, the mode will revert from the snapToMode back to the mode before addModeSnapback was invoked.
