[wxMax] Application inactivity timeout

BlitzMax Forums/Brucey's Modules/[wxMax] Application inactivity timeout

(Posted 2010) [#1]

I'm trying to setup automatic-logout with wxMax, but there seems to be no way in the wrapper to do it.
Searching around, someone mentioned something about wxApp::FilterEvent, but didn't say how it was used (and wxApp.FilterEvent does not exist - although there is commented-out code for it).
An easy way to do it would be to connect every event to a single function, but I haven't found a way to do that with one call (i.e. ConnectAny(wxEVT_ALL, OnEvent)).

I thought of a way to do it by rewriting TEventHandler.eventCallback (calling a separate callback for each event), but I would rather not modify wxMax.. it takes forever to compile.

Anyone have some suggestions?

I don't have any answers, just clarifying the question - you want your app to close or otherwise elegantly cope when the user logs off?

This code works on winxp.
I'm not sure about other platform.

SuperStrict

Framework wx.wxApp
import brl.timer
Import wx.wxFrame

type TIdleTimerEvent extends TEvent
	field maxTimeout% = 5 '5 secs
	field timeout%
	field eventcount%
	
	method Emit()
		eventcount = 1
		timeout:-1
		
		debuglog "Tick => " + timeout
		
		if timeout <= 0
			idleTimer.Stop()
			notify("Time to go to bed...")
		End If
	End Method
	
	method resetTimeout()
		if eventcount 'because ttimer will cause wxIdleEvent too, so we have to "skip" it
			eventcount:-1
		elseif timeout < maxTimeout
			debuglog "reset!"
			timeout = maxTimeout
		End If
	End Method

End Type

global idleTimerEvent:TIdleTimerEvent = new TIdleTimerEvent
global idleTimer:TTimer

Type MyApp Extends wxApp

	Field frame:wxFrame

	Method OnInit:Int()

		frame = wxFrame.CreateFrame(,, "Hello World", 100, 100)
		frame.SetExtraStyle(wxWS_EX_PROCESS_IDLE)
		frame.ConnectAny(wxEVT_IDLE, _onIdle)
		frame.show()
		idleTimer = createTimer(1, idleTimerEvent)
		Return True
	End Method
	
	
End Type


function _onIdle(ev:wxEvent)
	idleTimerEvent.resetTimeout()
End Function

New MyApp.run()

You need to subclass wxApp and implement FilterEvent yourself - to catch those events you are interested in.

Of course... that'll only be true once I've got it working properly.
It's a bit... um... complicated down there. I need to retrieve correct evthandler object, and then try to find the event object of the right type - which may, or may not work...

Yes, the idle timer is also a good idea :-)

I want to do some action (clear cached user-data, "logout" [not from the OS], etc.) when no events have been created for x amount of time (application is idle).

@Tommo: Thanks! That's exactly what I was trying to do.. though I never thought of doing it like that.

EDIT: Sadly, though, it does not work on Ubuntu :(

I've no linux here... sorry

Maybe you can write a simple customed wxEvtHandler in C++, and import it into your bmx app.
In such way you don't have to modify wx.mod.

filterEvent is going to require some major work on the framework... ho hum.

My head is spinning :-p

Watch this space...
