/*
cmUI implements a platform independent UI control manager
for multiple simultaneous applications. In this context
an 'application' can be seen as a plug-in style program.
The goal of the manager is to support the easy construction
of panels of graphic user interface controls.
Operation:
1) A cmUi manager is allocated by the master program. See cmUiAlloc().
2) The master program then assigns a 'driver' to implmenent
the commands issued by cmUi. All commands can be
described using the cmUiDriverArg_t record.
3) The master program then registers client applications with
the cmUi manager by calling cmUiCreateApp().
4) Prior to calling any of the client application functions
the master or client app. must call cmUiSetAppId(). This
function sets the current application id and thereby slightly
simplifies the client app interface by not requiring the
app id be passed with every client app. function call.
5) Once the current app. id is set with cmUiSetAppId()
the client app can make multiple calls to the cmUi manager
to create or query controls.
6) Calls to create controls result in callbacks to the
driver function which manages the actual windowing and
initial event handling.
7) Events generated by the driver based graphic controls
are routed back to the cmUi manager through calls to
cmUiOnDriverEvent().
8) The cmUiOnDriverEvent() internally caches the
state/value of the control based on the event information
and calls the 'cbFunc' function registered with the
cmUi manager by cmUiAlloc(). This call is intended to
notify the client applications of changes in the state/value
of a user interface control.
Notes:
1) Application id's must be unique among all applications.
Control id's must be unique among all controls assigned
to the same application. Both application and control id's
are used internally as array indexes they should therefore
be the low, positive, and densely packed integers.
2) All communication between the cmUi and the driver,
and all callbacks from the cmUi to the master app.
use the cmUiDriverArg_t structure
TODO:
0) Remove the 'cbArg' from the cmUiDriverArg_t record and
pass it as a separate paramenter in the cmUiDriverFunc_t calls.
1) The controls should be based on a multilevel tree model
not the simple two layer panel->controls framework used now.
2) Given that access to the control values can be non-blocked
and fast many controls won't need to report changes back to
the client - the client can simply read the control value
as necessary directly from the cmUi manager. To decrease
event processing overhead controls should therefore be
flagged as 'callback/no-callback'. Some controls like
buttons should default to turning the flag on, while other
controls, like numbers, should default to turning it off.
3) Implement support for the creation of arrays of controls.
This can be implemented with a scheme similar to 'next rect'.
cmUiSetupArray(uiH,panelId,baseCtlId,cnt).
4) Come up with a threading model. For example maybe
control creation should use a blocking scheme since it is
generally to time consuming to do during real-time operation
anyway. If the control flow generated from driver event
callbacks then allows value, but not structural changes,
then non blocking will be necessary.
5) The cmUiDriverArg_t structure is used for both
commands to the driver and callbacks from the driver.
Many of the fields are not use for event callbacks.
Which fields are used under which circumstances should
be documented. This would allow decreasing the size
of the record during serialization.7
6) Write a serialization/deserialization routines for cmUiDriverArg_t.
unsigned cmUiDriverArgSerialBufByteCount(const cmUiDriverArg_t* a);
cmUiRC_t cmUiDriverArgSerialize( const cmUiDriverArg_t* a, char* buf, bufByteCnt );
cmUiRC_t cmUiDriverArgDeserialize( cmUiDriverArg_t* a, const char* buf, bufByteCnt );
7) There is no duplex model for validating and then displaying the
value of a control.
