Editing WoW:Creating simple pop-up dialog boxes (section)

=== Editable text fields ===
To add a editbox in the popup set the ''hasEditBox'' option field to true. The EditBox gets the name "$parentEditBox", relative to the Popup, and is also available in the popup's ''.editBox'' field.  (Recall that the popup dialog is the value returned from the ''StaticPopup_Show()'' function.)  To get and set the value of the EditBox use the following code:

 OnShow = function (self, data)
     self.editBox:SetText("Some text goes here")
 end,
 OnAccept = function (self, data, data2)
     local text = self.editBox:GetText()
     -- do whatever you want with it
 end,
 hasEditBox = true

More complicated usage might be to use OnShow to call <tt>self.button1:Disable()</tt> (graying out the Accept button), and then including the following in your options table to allow the Accept button to be clicked as soon as the user types something in the text field:

 EditBoxOnTextChanged = function (self, data)   -- careful! 'self' here points to the editbox, not the dialog
     self:GetParent().button1:Enable()          -- self:GetParent() is the dialog
 end

Using ''hasEditBox''/''.editBox'' causes a small one-line text field to appear.  You can use the ''hasWideEditBox'' option field (and the corresponding ''.wideEditBox'' dialog field) to cause the text field to have the full width of the dialog box instead.  To do this, you must set both options, but only the wide edit box will be used.  Both normal and wide editboxes will respect the ''maxLetters'' field if you set it (most editbox popups used by Blizzard set this to 24 or 31).
