F# Using F#, WPF, FsXaml, a Menu, and a Dialog Box Create the main window in XAML
Example
You have to create a XAML file that defines the main window that contains our menu and drawing space. Here's the XAML code in MainWindow.xaml:
<!-- This defines the main window, with a menu and a canvas. Note that the Height
and Width are overridden in code to be 2/3 the dimensions of the screen -->
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Spirograph" Height="200" Width="300">
<!-- Define a grid with 3 rows: Title bar, menu bar, and canvas. By default
there is only one column -->
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<!-- Define the menu entries -->
<Menu Grid.Row="0">
<MenuItem Header="File">
<MenuItem Header="Exit"
Name="menuExit"/>
</MenuItem>
<MenuItem Header="Spirograph">
<MenuItem Header="Parameters..."
Name="menuParameters"/>
<MenuItem Header="Draw"
Name="menuDraw"/>
</MenuItem>
<MenuItem Header="Help">
<MenuItem Header="About"
Name="menuAbout"/>
</MenuItem>
</Menu>
<!-- This is a canvas for drawing on. If you don't specify the coordinates
for Left and Top you will get NaN for those values -->
<Canvas Grid.Row="1" Name="myCanvas" Left="0" Top="0">
</Canvas>
</Grid>
</Window>
Comments are usually not included in XAML files, which I think is a mistake. I've added some comments to all the XAML files in this project. I don't assert they are the best comments ever written, but they at least show how a comment should be formatted. Note that nested comments are not allowed in XAML.
