"""Creates a popup dialog to alert and/or interact with user.
Some of the main keywords that can be used to customize the dialog:
Parameters:
text (str): Text message/query displayed to user
geom: Geometry to be displayed in dialog
buttonTextList: List of text to show on each button
buttonGeomList: List of geometry to show on each button
buttonImageList: List of images to show on each button
buttonValueList: List of values sent to dialog command for
each button. If value is [] then the ordinal rank of
the button is used as its value.
buttonHotKeyList: List of hotkeys to bind to each button.
Typing the hotkey is equivalent to pressing the
corresponding button.
suppressKeys: Set to true if you wish to suppress keys
(i.e. Dialog eats key event), false if you wish Dialog
to pass along key event.
buttonSize: 4-tuple used to specify custom size for each
button (to make bigger then geom/text for example)
pad: Space between border and interior graphics
topPad: Extra space added above text/geom/image
midPad: Extra space added between text/buttons
sidePad: Extra space added to either side of text/buttons
buttonPadSF: Scale factor used to expand/contract button
horizontal spacing
command: Callback command used when a button is pressed.
Value supplied to command depends on values in
buttonValueList.
Note:
The number of buttons on the dialog depends on the maximum
length of any button[Text|Geom|Image|Value]List specified.
Values of None are substituted for lists that are shorter
than the max length
