Using XAML

 

Using XAML

Now that we have a parameter-less constructor we can try the Shape class out with XAML.

The only thing we have to do is make sure that we include the namespace of the current project in the XAML file. Assuming that the project is called "trees" the Window tag has to be updated to read:

<Window x:Class="trees.Window1"
xmlns="http://schemas.microsoft.com/
winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/
winfx/2006/xaml"
xmlns:m="clr-namespace:trees
"Title="Window1" Height="300"
Width="300">

Following this we can add a Tree object using something like:

<m:Tree L="50" s="0.8" t="90" dt="20" 
d="8" X="150" Y="200" Stroke="Red"
Height="220" Width="289"></m:Tree>

If you try this you will see a tree in the Designer and at run time.

A tree in the Designer

As for integrating the Tree class with XAML everything works as well as can be expected. If you compare the behavior with another Shape class-derived graphic such as Line you will see that it works just as well. In the Designer however there are some differences. In particular the five essential properties are listed in the Property Window and you can update them by entering new values but the Tree doesn't update unless you refresh the Designer.

There are a number of other facilities that don't appear to work properly in the Designer and to find out how to make these work we need to look more closely at the way the properties are defined - the subject of a future article.

The bitmap transform classes

WPF bitmaps are immutable but that doesn't mean you can't transform them. Find out about rotation, scaling, changing pixel formatting and how to mangage color profiles.

Loading Bitmaps: DoEvents and the closure pattern

How XAML works - Creating Objects With XAML

XAML can be confusing - especially if you think it is a markup language like HTML - it isn't. XAML is a general purpose object instantiation language and to find out what this means - read on.
