有没有办法使禁用的按钮上的图像饱和？ [英] Is there a way to desaturate an Image on a Button thats disabled?

问题描述

有没有办法使已禁用的按钮中的图像饱和？例如。 ICommand.CanExecute = false ？还是我需要使用单独的图像+样式/触发器

Is there a way I can desaturate images in Buttons that are disabled? eg. ICommand.CanExecute = false? or do I need to use separate images + Style/Triggers

推荐答案

我为此使用了特殊样式，这减少了禁用按钮时图像的不透明度（是的，如果按钮绑定到命令，这也可以使用）。从技术上讲，这不是去饱和，但它看起来很相似，并且可以帮助您自己得出解决方案：

I'm using a special style for this, which reduces the opacity of the image when the button gets disabled (yes, this also works if the button is bound to a command). Technically, this is not desaturation, but it looks similar and it might help you derive a solution on your own:

<Style x:Key="buttonImage">
    <Style.Triggers>
        <DataTrigger Binding="{Binding RelativeSource={RelativeSource AncestorType={x:Type Button}, AncestorLevel=1}, Path=IsEnabled}" Value="False">
            <Setter Property="Image.Opacity" Value="0.25"></Setter>
        </DataTrigger>
    </Style.Triggers>
</Style>
