Not really, it's more like the other way around. Whatever caused the problem quietly went away and just worked like a charm when I wanted to take another look at it. Perhaps I have frienly Kobolds or Elves in my house that secretly fixed it overnight.

I was working on the sample program to demonstrate my UI again. This time I'm grimly determined to write an article about it. I'm a little proud of that particular bit of code and I think it may be far enough to be of use to other people.

This is the XAML for a small view (as in Model View Presenter). Since the 3D engine is not running in the background, this view just fills the background with an image and a button to end the program that comes useful when the program runs in fullscreen mode:

<BackgroundView Id="BackgroundView" Width="1024" Height="768" DockStyle="ADAPT"
                xmlns="clr-namespace:FoC.PraetorUIDemo.Presentation.Views;assembly=PraetorUIDemo"
			    xmlns:fw="clr-namespace:Microsoft.Xna.Framework;assembly=MonoGame.Framework"             
                xmlns:foc="clr-namespace:FoC.Praetor4UI.Controls;assembly=Praetor4UI" 
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <foc:cPraeImage Id="ImgBackground" PositionX="0" PositionY="0" Width="1024" Height="768" Alpha="255" ImagePosition="SCALE" Image="Background" >
    	<foc:cPraeImageButton Id="BtnTerminate" Image="Button_96" PositionX="918" PositionY="10" Width="96" Height="20" Text="Exit" LeftButtonClicked="BtnTerminateProgram_LeftButtonClicked"/>
    </foc:cPraeImage>
</BackgroundView>

The click event of the button should be wired up to its event handler like this:

LeftButtonClicked="BtnTerminateProgram_LeftButtonClicked"

This never worked up to now. Since I don't enjoy the comfort of a designer that generates things like that in a partial class, I had to write code like this for every control:

public override void Initialize()
{
    m_BtnTerminateProgram = Controls.GetComponent("BtnTerminate") as cPraeImageButton;
    if (m_BtnTerminateProgram != null)
    {
        m_BtnTerminateProgram.LeftButtonClicked += new
                PraeMouseButtonEvent(BtnTerminateProgram_LeftButtonClicked);
    }
}

This worked, but for larger views with many controls this meant to write a awkwardly long method. Not anymore! Wiring up the button from XAML now works without any additional code in the Initialize() method.

Thanks, Elves!

This is Javascript. If you put big wheels and a racing stripe on a golf cart, it's still a f***ing golf cart.

What does m_ mean?

What does the tiny little c in front of PraeImageButton mean?

What does Btn stand for?

I am giving you hard time here but in our shop you have no choice but to name the control TerminateProgramButton. Your code would fail review any other way.

-- Thanks for sharing.

You have hit a hot topic there. I have been at war with those elaborate naming and style conventions for a long time.

Hungarion notation is not a bad thing at all, at least if you use it as it was meant to be and not simply as a type prefix. The typical 'we have Intellisense' argument also does not really fit anymore then and Intellisense usually fails me when I need it most. Besides that, I often must use editors that don't have any Intellisense.

Maybe I would not pass a review in your shop, but you would probably pass them in mine. The problem is that if you want to cover every possible case, you end up with a rulebook thicker than the German tax legislation. Been there, done that. With every review some new rules were added and, for my part, I hated it more every time I had to do a review.

The compiler does not care about any of this as long as the code is sytactically correct. Thw whole circus is just for us and I think there are more important things to look at in a code review than spending 90% of the time obscessing over wether or not someone should have captalized a name or not.

We are all intelligent people, so why can't we stick to essentials, keep the rulebook thin and allow a little anarchy within certain boundaries (Nerds and buerocrats avert your eyes). Conventions like using hungarion or not should be agreed upon by the team and then be used accordingly, but it's not the end of the world when someone accidentally or with some intention writes his stuff differently.

Good idea. Ask five programmers and you get twenty opinions. That's exactly how those style bibles with their endless rules come to be.

I have to ask - does your company also place that degree of attention to code clarity, performance, security and extensibility in code reviews? Smile | :)

I call that kind of project a hamster wheel. You can keep running in it as much as you want, but never arrive anywhere. Just look at my post after yours and you know my current hamster wheel. Smile | :)

It is my experience that as far as developers are concerned, the effect is cause by crappy project managers and/or customers who argue internally and can't make up their mind how they want it...

Not always: I worked with one "developer" years ago who got asked to fix bug A.
The fix caused bug B, so that had to be fixed.
The fix for bug B caused bug A, so the same fix was done again.
And again.
And again.

Until the customer said "sod this for a lark" and sent all the kit back... Sigh | :sigh:

A photon wouldn't experience Zeno's paradox since it doesn't experience time. Only an external observer would - and this is the same with software projects. Developers exist in a state without any concept of time but only external observers (managers, spouses, security guards wanting to lock the building) do.
