Hello,
I have a suggestion for all rubbon classes that currently use ImageSource to show an icon. In many cases I prefer to use visual elements, like Path, to make a button icon. It's faster to define and more flexible than images. I can not do it for the RibbonButton because it has no Content property, and its control template includes only the Image element. I made a workaround, changing the RibbonButton templates to show a ContentControl which is binded to Tag property (can be an attached property):
<!-- Old template -->
<Image
x:Name="Image"
Margin="1"
VerticalAlignment="Center"
Stretch="Uniform"
Width="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=ImageSourceSmallSize.Width}"
Height="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=ImageSourceSmallSize.Height}"
Source="{TemplateBinding ImageSourceSmall}"
SnapsToDevicePixels="True" />
<!-- New template --><Viewbox x:Name="Image"
Margin="1"
VerticalAlignment="Center"
Stretch="Uniform"
Width="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=ImageSourceSmallSize.Width}"
Height="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=ImageSourceSmallSize.Height}"
SnapsToDevicePixels="True" >
<ContentPresenter Content="{TemplateBinding Tag}"/>
</Viewbox>
Then I assign visual element that draws an icon to the Tag property in my XAML files . It works, but having a dedicated Content property would be better (it allows to use images as well).
However, I've got a unexpected problem in my workaround. When any RibbonButton with 'Tag icon' is send to QAT (via a content menu), its icon on the button itself vanishes. Thus, the icon is copied to QAT but erased on the button in the ribbon tab. To get back the icon, I need to remove button from QAT and restart an application. I guess, it's related to control cloning for QAT.
Is there a fast solution for this problem?
Thanks in advance!
Ilia
