Ptr<TextureSource> source = *new TextureSource("Themes/Images/icon_MDD_blue1.png");
Ptr<Image> image = *new Image();
image->SetSource(source.GetPtr());
I created the following sample that shows how to bind an ImageSource (or TextureSource) property to an Image element:Thanks, that works. But how do I bind to it? I've tried to expose a property in the code-behind and tried all of these types:
- TextureSource
- Image
- ImageSource
The problem is when I try to bind to that property from the xaml...
<Image HorizontalAlignment="Left" Width="32" Height="32" Margin="4,0,0,0" Source="{Binding ItemImage}"/>
I get this runtime error:
Can't create ComponentConverter<ImageSource>, it is not registered

}This was fixed in b7.There is only a restriction now (we are going to fix in the next release), the exposed property must be a Ptr type, you cannot use a Getter/Setter returning a pointer to the ImageSource:
This is probably because an older version of NoesisGUI is being loaded. The latest beta is versioned this way:I get the following runtime error when I run
requires version 1.2.0 or later, but Noesis.dylib provides version 1.0.0
otool -L Noesis.dylib
