Dialogs

Written by Andrew Graham

This library contains several modal, that is blocking, dialogs by which the user
can enter data. Presently they are an InputDialog for text, a TimeDialog for times,
a DateDialog for dates, both a ColorDialog and a ColorPickerDialog for colors, a
NumberDialog for numbers,a FileDialog for folders and file names and a CustomDialog.

Android does not provide modal dialogs but a special mechanism to permit this exists
in Basic4android. The Android Activity lifetime system makes this support complicated
because Activities can be created and destroyed at will by the OS. To avoid stack
runaway on the GUI thread when an Activity is destroyed the stack must be unwound to
the lowest level. The Basic4android modal mechanism does this by closing any modal
dialog being shown and exiting the Sub that called the dialog, and any Sub that called
that Sub and so on, in order to return the main thread to the message loop. This means
that the application does not necessarily receive a return value from the dialog and has
its expected flow of execution interrupted. This will probably most often happen if the
device is rotated while a modal dialog is displayed so the Activity is destroyed and rebuilt
with a new layout.

Because this may happen unexpectedly applications, depending upon their logical structure,
may need code in the Pause and Resume Subs to deal with the fact that modal dialog closure
may not always be detected. Setting a process global when a modal dialog is shown and
clearing it when it returns with some checking code in the Resume Sub is one way of dealing
with this possibility.

The above discussion also applies the Basic4android modal dialogs InputList, InputMultiList,
Msgbox and Msgbox2.
