I'm looking at this event from Mainmenu.dll when starting the application. Is this behavior correct?

Is the raiseSystemEvent(eFunction.TransitionToPanel... missing in the code below?

Code:

       private static void loadMainMenu()
        {

            Assembly pluginAssembly = Assembly.Load("UI");
            IHighLevel availablePlugin = (IHighLevel)Activator.CreateInstance(pluginAssembly.GetTypes()[0]);
            pluginCollection.Add(availablePlugin);
            availablePlugin.initialize(theHost);
            
            pluginAssembly = Assembly.Load("MainMenu");
            IHighLevel mmPlugin = (IHighLevel)Activator.CreateInstance(pluginAssembly.GetTypes()[0]);
            pluginCollection.Add(mmPlugin);
            mmPlugin.initialize(theHost);
            
            
            for (int i = 0; i <UICollection.Count; i++)
            {
                UICollection[i].transitionInPanel(availablePlugin.loadPanel("", i));
                UICollection[i].transitionInPanel(mmPlugin.loadPanel("", i));
                UICollection[i].executeTransition(eGlobalTransition.None);
            }
            
        }

I changed the code to this to make it trigg the events:

Code:

        private static void loadMainMenu()
        {

            Assembly pluginAssembly = Assembly.Load("UI");
            IHighLevel availablePlugin = (IHighLevel)Activator.CreateInstance(pluginAssembly.GetTypes()[0]);
            pluginCollection.Add(availablePlugin);
            availablePlugin.initialize(theHost);
            
            pluginAssembly = Assembly.Load("MainMenu");
            IHighLevel mmPlugin = (IHighLevel)Activator.CreateInstance(pluginAssembly.GetTypes()[0]);
            pluginCollection.Add(mmPlugin);
            mmPlugin.initialize(theHost);
            
            
            for (int i = 0; i <UICollection.Count; i++)
            {
                UICollection[i].transitionInPanel(availablePlugin.loadPanel("", i));
                UICollection[i].transitionInPanel(mmPlugin.loadPanel("", i));
                
                // Changed by Borte:
                UICollection[i].executeTransition(eGlobalTransition.None);

                // Added by Borte:
                theHost.raiseSystemEvent(eFunction.TransitionToPanel, i.ToString(), "Core", "");
            }
            
        }

How can I make a control redraw itself? It doesnt redraw it self when I change the "left" property of a control. When I debug the code the control jumps into "refreshMe" but exists since nothing is connected to the UpdateThisControl event.

If your only worried about detecting when the panel is loaded at the beginning just start the effect when the panel is initialized. initialize is called right before the panel is actually displayed so it should work just as well.

If a control is loaded then the screen which is drawing it will hook the UpdateThisControl event. So if nothing is hooking that event then that control is not the one being displayed.

But the TransitionToPanel event should still be loaded everytime an panel is shown, regardless off where it was shown from. At least for consistency.

Edit:
Was finally able to redraw the control. I was declaring a private control (like in the code above) but it turned out that this control did not get the UpdateThisControl event populated. Instead it was a clone of the control (this clone was created when the panel was loaded) that got this UpdateThisControl populated. I had to loop trough the controls that an panel reported as it's contents to be able to find the control that I could redraw.

Why is this created as a clone?
It makes it a lot harder for a skin to control it's controls when it first has to create a new control, load this new control to a panel, load this new panel to a screen and then to later control it I have to search for this other cloned control (which is a copy of the loaded control) in the controlslist of a screen.
And I could not use the one in my local panel object either since this doesn't hold the cloned control (hence not the updated UpdateThisControl event).

The objects that's being passed on by a click event or some other events are the cloned one with the correct UpdateThisControl event so it works if I use that one, but in my case I don't have this source object.

This seems somewhat backwards to me that I can't use the properties of my locally created controls.

I sure hope this explanation made some sense, if not give a shout and I'll try to explain better.

btw: Here is the code I used to find the control in the screen:

Code:

                for (int i = 0; i < Screen[0].controlCount; i++)
                {
                    if (Screen[0].getControl(i).Name == "LeftMenuBar")
                        Screen[0].getControl(i).Left = Animation_Count;
                }

Edit2:
Been thinking some more about this cloneing behavior and I think it's problably due to the fact that OM can utilize multiple screens, thereby creating the need for different animations at different times on the different screens. Am I right? Or is it intended to show the same on all screens at all times (like a cloned display)?

If so then I think that any event should have a screen parameter passed on so that any animation or control parameter change can be initiated on the correct screen.

The click event has the screen parameter but the system event is missing this one.

Cheers

I had to loop trough the controls that an panel reported as it's contents to be able to find the control that I could redraw.

Why is this created as a clone?
It makes it a lot harder for a skin to control it's controls when it first has to create a new control, load this new control to a panel, load this new panel to a screen and then to later control it I have to search for this other cloned control (which is a copy of the loaded control) in the controlslist of a screen.
And I could not use the one in my local panel object either since this doesn't hold the cloned control (hence not the updated UpdateThisControl event).

The objects that's being passed on by a click event or some other events are the cloned one with the correct UpdateThisControl event so it works if I use that one, but in my case I don't have this source object.

This seems somewhat backwards to me that I can't use the properties of my locally created controls.

I sure hope this explanation made some sense, if not give a shout and I'll try to explain better.

btw: Here is the code I used to find the control in the screen:

Code:

                for (int i = 0; i < Screen[0].controlCount; i++)
                {
                    if (Screen[0].getControl(i).Name == "LeftMenuBar")
                        Screen[0].getControl(i).Left = Animation_Count;
                }

Edit2:
Been thinking some more about this cloneing behavior and I think it's problably due to the fact that OM can utilize multiple screens, thereby creating the need for different animations at different times on the different screens. Am I right? Or is it intended to show the same on all screens at all times (like a cloned display)?

If so then I think that any event should have a screen parameter passed on so that any animation or control parameter change can be initiated on the correct screen.

The click event has the screen parameter but the system event is missing this one.

Yup your thinking in terms of a single screen. One screen my be displayed and the other may be transitioning which is why we need to use screen specific references and its much simpler then your making it.

I'm a little short on time so sorry if this answer seems rushed (and if any of it is unclear let me know)

1. Arg1 of the transition to panel command is the screen number. In fact the first argument of any function that is screen specific is the screen number.
2. You cant reference the base control for exactly the reason you said, there would be no way to know what screen you want to control, instead its this simple:
This

Code:

LeftMenuBar.Left = Animation_Count;

should be this

Code:

Screen[screenNumber]["LeftMenuBar"].Left = Animation_Count;

Just make sure screenNumber is set properly.
3. If this animation is only the very first time the panel is displayed you may want to consider using the initialize event like I said before, and only using a single control instance for the opening transition. Then when the transition is complete, load the panel into the screen manager and use that from then on.
4. Your right, for consistency, I will make sure the core raises a transition to panel event when loading the main menu. For performance it won't fire when when loading the UI though, since the UI can only be loaded once (and when that happens initialize is called).

I got the startup animation working now. Thanks for the help.

Btw: I changed the screens behavior so that each screen opens on each separate monitor instad of all on the primary. I figured that this behaviour would be more correct in a multi monitor enviroment.
Anyway here is the lines I added in the contructor in ui.cs (ui form code) if it's of any interest:

Code:

this.StartPosition = FormStartPosition.Manual;
this.Bounds = System.Windows.Forms.Screen.AllScreens[s].Bounds;

Good call...the plan is to allow screens to be assignable (for example 3 screens on the first second and fourth monitor would be possible instead of on all four) and not necessarily represent the physical screen numbers but until then i'll throw in the above code.

Extide:
Latest commit should have all the paths set right...

Thanks for adding it.

- If you wanna have three screen on one monitor then it might be necessary to be able to set startup size and startup location of each screen to prevent them from launching on top of each other.

A general question for controls:
- Could an "visible" and / or enabled property be added? This would help for controlling the controles from a skin.


Control highlightning:
Some of the controls reacts to mouse over (wich sets the modeType.Highlighted) for the control and renders it accordingly. What do I do I do if I don't want to use this highlight mode but instead have my skin create an highlight effect.

Also for the textbox control the backcolor property is fixed at white, this needs to be controllabe from the skin, rather than fixed.

I'm currently trying to build a skin that's completely different (in both appearance and functionality) than what's provided with OpenMobile right now. Is OpenMobile supposed to be able to create just about any skin that an user can think of or is it supposed to be somewhat limited to provide a more unified approach? If it's the later I personally think it's a bad thing since a lot of people would like to create a skin that would "mimic" an oem system and that would not be possible if OpenMobile is set to have a unified approach.

Should OpenMobile skins behave according to a set of rules or is it all up to what the skinner would like (like using OpenMobile to just provide a base and tools for the skinner)?

If you don't mind Justin then I can change/add (but not remove) whatever code I need to support the skin I'm creating and mark any changes I do so that you can review them and maybe integrate them into the main code.

I'm currently working off revision 54 though so my code changes would be based on that version.

Yea eventually I can add that in...but its pretty low on the list because I can't imagine anyone needing to do that.

Can you give an example of what your trying to do? (like what effect to what control) So I can see if theres an easy way or what changes might be necessary.

OpenMobile standardizes the back end but leaves the look and feel stuff completely up to the skin designer. There are a few rules which say this way of doing something is better then this way but thats more for the other plugins not the skins. I'll post a link to what i'm talking about when I finish writing it but the short answer is any skin you can think of.

Thats fine-as long as your ok with the possibility that the features your want may be implemented differently...if you want to add yourself to the sourceforge project I can give you your own svn branch to play around with.
