Simple modal dialog

Scripting Issues
1

Is there a simple way to create what is in effect a modal dialog?

There are pts in my game where the user has the option to stop/pause and select an option from a frame I will put up.

I just want to prevent the possibility of the user clicking something outside the frame which should not be allowed.

Never tried that in Panda, but in HTML you usually make a 100% x 100% big half-transparent plane.

This should work in Panda as well. Make a big plane, put it in front of all other GUI elements and place your modal dialog in front of that veil.

Good idea! thx!

Note that DirectDialog (and its related classes OkDialog and so on) does this by default if you specify fadeScreen = True to the constructor.

Trying out fadeScreen, but I can still click the button behind the dialog . Am I not using it correctly?

import direct.directbase.DirectStart
from direct.gui.DirectGui import *

def click():
	print "clicked"

dialog = DirectDialog(fadeScreen=True)
b = DirectButton(text = ("OK", "click!", "rolling over", "disabled"), frameSize=(-.5,.5,-.5,.5), scale=.1, command=click)
run()

You need to call dialog.show() to activate it. And you probably want to have some text and/or buttons on your dialog:

import direct.directbase.DirectStart
from direct.gui.DirectGui import *

def click():
   print "clicked"

dialog = OkDialog(fadeScreen=True, text = 'this dialog')
dialog.show()

b = DirectButton(text = ("OK", "click!", "rolling over", "disabled"), frameSize=(-.5,.5,-.5,.5), scale=.1, command=click)
run()

Thanks!
.show() was what I was missing.

It seems to make everything behind the dialog black, though, can I control this, i.e. make it grayed-out rather than completely dark?

Oh, my mistake. Instead of specifying fadeScreen = True, you should specify fadeScreen = 0.5, or whatever level of black you want it to have.
