Cancel button in nsDialogs

[rthawley]

How do I tell if the Cancel button has been pressed in a nsDialogs dialogbox?

nsDialogs doesn't appear to have a built in handler so the best thing I can think of is to set a variable to 1 before ::Show and to 0 in the custom page's leave callback function (and in the previous page's pre callback function if there is a previous page). Then check the variable value in your abort callback function (set using MUI_CUSTOMFUNCTION_ABORT) to determine whether or not the user cancelled while on your custom page. Your other option is to write a plug-in which grabs the value of extra_parameters->abort (set to 1 after Cancel has been pressed).

This is often asked for feature. Maybe it will be added in next release.

Why, are you planning to add it?

You should really only make changes outside $pluginsdir on the instfiles page so IMHO catching cancel seems wrong...

Yes that's the plan, but there is too much items on my To-Do list
