Support for wrapping text in vizdlg panels will be added in a future update. In the meantime, you can use the following code to enable text wrapping with Vizard 5.1:

import viz
import vizdlg
import vizact
viz.go()

class WrappedText(viz.VizText):

	def __init__(self, message, wrapWidth=None, **kw):
		viz.VizText.__init__(self,viz.addText(message, **kw).id)
		self._wrapWidth = None
		self.setWrapWidth(wrapWidth)

	def setWrapWidth(self, width):
		"""Set width at which text is wrapped"""
		if width != self._wrapWidth:
			self._wrapWidth = width
			if width is None:
				self.setBoxTransform(viz.BOX_DISABLED)
			else:
				self.setBoxTransform(viz.BOX_ENABLED | viz.BOX_FIXED)
				self.setBoxOffset([0.0, 0.0, width, 0.0])
				self.setTextOverflow(viz.OVERFLOW_WRAP)

			parent = getattr(self, '_parentPanel', None)
			if parent is not None:
				panel = parent()
				if panel is not None:
					panel.dirtyLayout()

	def getWrapWidth(self):
		"""Get width at which text is wrapped"""
		return self._wrapWidth

panel = vizdlg.Panel()
panel.setScreenAlignment(viz.ALIGN_CENTER)
text = panel.addItem(WrappedText(message, wrapWidth=200))

grow_action = vizact.call(text.setWrapWidth, vizact.mix(begin=200, end=500, time=1.0, interpolate=vizact.easeOutStrong))
shrink_action = vizact.call(text.setWrapWidth, vizact.mix(begin=500, end=200, time=1.0, interpolate=vizact.easeOutStrong))

vizact.onkeydown(' ', text.runAction, vizact.choice([grow_action,shrink_action]))
