# DirectDialog¶

DirectDialog objects are popup windows to alert or interact with the user. It is invoked just like the other DirectGUI objects, but it also has some unique keywords. Integral to DirectDialog are dialogName, buttonTextList, buttonImageList, and buttonValueList. The dialogName should ideally be the name of the NodePath created to hold the object. The button lists contain the various properties of the buttons within the dialog box. No maximum number of buttons needs to be declared.

Panda3D contains a number of shortcuts for common dialog options. For example, rather than specifying the rather common text list (“Yes”,”No”), there is a YesNoDialog that functions exactly like a normal dialog but has buttonTextList already defined. The other similar dialogs are OkCancelDialog, OkDialog, RetryCancelDialog, and YesNoCancelDialog.

## YesNo Dialog Example¶

import direct.directbase.DirectStart
from direct.gui.OnscreenText import OnscreenText
from direct.gui.DirectGui import *
from direct.actor import Actor
from direct.interval.IntervalGlobal import *
from panda3d.core import *

bk_text = "DirectDialog- YesNoDialog Demo"
textObject = OnscreenText(text=bk_text, pos=(0.85,0.85),
scale=0.07, fg=(1, 0.5, 0.5, 1), align=TextNode.ACenter, mayChange=1)

output = ""
textObject = OnscreenText(text=output, pos=(0.95,-0.95),
scale=0.07, fg=(1, 0.5, 0.5, 1), align=TextNode.ACenter, mayChange=1)

# Callback function to set text
def itemSel(arg):
if arg:
output = "Button Selected is: Yes"
else:
output = "Button Selected is: No"
textObject.setText(output)

# Create a frame

The OkDialog causes an error if being created a second time after destroying it with myOkDialog.destroy(). To solve this you can use:
myOkDialog.cleanup()
