WPF按鈕觸發圖標更改
[英]WPF Button trigger icon change
問題描述
您好，首先感謝您為我指明正確方向的任何幫助。 我在WPF中有一個應用程序開始引起我問題。 我對The Basics沒問題，但是現在我對它的了解越來越深，而且我不確定這是否是我的知識不足或XAML的局限性。
我的應用程序具有RadioButtons，我正在使用一種樣式，使用BasedOn屬性將它們作為ToggleButtons返回。
所有這些都很好，此樣式中包括樣式信息以及OnClick和鼠標事件的觸發事件，這些事件會覆蓋默認操作。
我遇到的問題是，當我選中單選按鈕IsChecked時，我希望能夠換出內容（圖標圖像）。
為此，我無法以樣式對圖像進行硬編碼，並且我不想在每個按鈕中都放置所有有關OnClick，MouseOver等的樣式信息。
我試圖在RadioButton本身中添加其他樣式，並以我當前使用的樣式為基礎，但是該代碼並未更新Content（Icon Image）。 我可以找到的唯一示例是控件模板，如果我在模板OnChecked內設置邊框，它將顯示邊框，但是我不確定是否使用正確的屬性來更改單選按鈕的內容。
具有所有觸發器的父樣式如下所示
<Style x:Key="RadioBtnToolStyle" BasedOn="{StaticResource {x:Type ToggleButton}}" TargetType="{x:Type RadioButton}">
<Setter Property="Background" Value="{x:Null}" />
<Setter Property="HorizontalAlignment" Value="Center" />
<Setter Property="Foreground" Value="{x:Null}" />
<Setter Property="Padding" Value="0" />
<Setter Property="Margin" Value="3" />
<Setter Property="BorderBrush" Value="{x:Null}" />
<Setter Property="RenderTransform">
<Setter.Value>
<ScaleTransform CenterX="30" CenterY="30" ScaleX="1" ScaleY="1" />
</Setter.Value>
</Setter>
<Setter Property="OverridesDefaultStyle" Value="True" />
<Setter Property="Cursor" Value="Hand" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="RadioButton">
<Border Name="border" BorderThickness="0" BorderBrush="Black" Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Opacity" Value="0.8" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsPressed" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation From="1" To="0.8" RepeatBehavior="Forever" AutoReverse="True" Duration="00:00:00.6" Storyboard.TargetProperty="RenderTransform.ScaleX" />
<DoubleAnimation From="1" To="0.8" RepeatBehavior="Forever" AutoReverse="True" Duration="00:00:00.6" Storyboard.TargetProperty="RenderTransform.ScaleY" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation To="1" Duration="00:00:00.6" Storyboard.TargetProperty="RenderTransform.ScaleX" />
<DoubleAnimation To="1" Duration="00:00:00.6" Storyboard.TargetProperty="RenderTransform.ScaleY" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</Style.Triggers>
</Style>
我的按鈕帶有我添加的樣式，目前看起來像這樣
<RadioButton GroupName="Tools" Grid.Row="0" Content="{StaticResource BrightnessContrast}" IsChecked="{Binding IsBrightnessAndContrastEnabled}">
<RadioButton.Style>
<Style TargetType="RadioButton" BasedOn="{StaticResource RadioBtnToolStyle}">
<Setter Property="OverridesDefaultStyle" Value="True" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="RadioButton">
<ContentPresenter Content="{StaticResource BrightnessContrast}" HorizontalAlignment="Center" VerticalAlignment="Center" />
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Content" Value="{StaticResource InvertImageBtn}" />
</Trigger>
<Trigger Property="IsChecked" Value="False">
<Setter Property="Content" Value="{StaticResource LogoFooterBackgroundStyle}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</RadioButton.Style>
</RadioButton>
我已經看到使用事件的一兩個示例，但是到目前為止，我設法避免在代碼中寫入任何內容並將其包含在ViewModel中，因此，如果在XAMl中可以做到這一點，那將是完美的。
抱歉，如果我對此解釋不佳，再次感謝您的幫助。

首先，即使您將樣式基於切換按鈕樣式，也必須在視圖模型中管理RadioButton的IsChecked狀態。 如果您能做到，那就太好了。 其次，如果您以基本樣式制動控制模板，則進一步的制動嘗試是多余的，因為您只是制動了破壞原點的前一個制動模板。 因此，如果要給控件提供新的外觀，請嘗試以控件樣式重新模板化ContentTemplate。 在您的情況下，您更改了原始模板，因此沒有復選標記區域，僅顯示內容。 關於示例：1.這是RadioButton更改其內部項目符號（復選標記區域），並根據需要添加自己的畫筆：
<ImageBrush x:Key="CheckedBullet" ImageSource="MyResources/Koala.jpg"/>
<ImageBrush x:Key="UnCheckedBullet" ImageSource="MyResources/Penguins.jpg"/>
<Style x:Key="MyRadioButton" TargetType="{x:Type RadioButton}">
<Setter Property="SnapsToDevicePixels" Value="true"/>
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="FocusVisualStyle" Value="{StaticResource RadioButtonFocusVisual}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RadioButton}">
<BulletDecorator Background="Transparent">
<BulletDecorator.Bullet>
<Grid Width="50" Height="50" >
<Ellipse x:Name="Border"
Fill="{StaticResource NormalBrush}"
StrokeThickness="1"
Stroke="{StaticResource NormalBorderBrush}" />
<Ellipse Margin="3" x:Name="CheckMark" IsHitTestVisible="False"/>
</Grid>
</BulletDecorator.Bullet>
<ContentPresenter
Margin="4,0,0,0"
VerticalAlignment="Center"
HorizontalAlignment="Left"
RecognizesAccessKey="True"/>
</BulletDecorator>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter TargetName="CheckMark" Property="Fill" Value="{StaticResource CheckedBullet}"/>
</Trigger>
<Trigger Property="IsChecked" Value="False">
<Setter TargetName="CheckMark" Property="Fill" Value="{StaticResource UnCheckedBullet}"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter TargetName="Border" Property="Fill" Value="{StaticResource DarkBrush}" />
</Trigger>
<Trigger Property="IsPressed" Value="true">
<Setter TargetName="Border" Property="Fill" Value="{StaticResource PressedBrush}" />
<Setter TargetName="Border" Property="Stroke" Value="{StaticResource GlyphBrush}" />
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter TargetName="Border" Property="Fill" Value="{StaticResource DisabledBackgroundBrush}" />
<Setter TargetName="Border" Property="Stroke" Value="#40000000" />
<Setter Property="Foreground" Value="#80000000"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<!--xaml code that use the style MyRadioButton defined above-->
<RadioButton HorizontalAlignment="Center" VerticalAlignment="Center"
IsChecked="{Binding IsBrightnessAndContrastEnabled, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">
<RadioButton.Style>
<Style TargetType="RadioButton" BasedOn="{StaticResource MyRadioButton}">
<Style.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Content" Value="Checked!!!" />
</Trigger>
<Trigger Property="IsChecked" Value="False">
<Setter Property="Content" Value="Check me!!!" />
</Trigger>
</Style.Triggers>
</Style>
</RadioButton.Style>
</RadioButton>
這是上述樣式的畫筆：
<Style x:Key="RadioButtonFocusVisual"> <Setter Property="Control.Template"> <Setter.Value> <ControlTemplate> <Border> <Rectangle Margin="15,0,0,0" StrokeThickness="1" Stroke="#60000000" StrokeDashArray="1 2"/> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> <!-- Fill Brushes --> <LinearGradientBrush x:Key="NormalBrush" StartPoint="0,0" EndPoint="0,1"> <GradientBrush.GradientStops> <GradientStopCollection> <GradientStop Color="#FFF" Offset="0.0"/> <GradientStop Color="#CCC" Offset="1.0"/> </GradientStopCollection> </GradientBrush.GradientStops> </LinearGradientBrush> <LinearGradientBrush x:Key="HorizontalNormalBrush" StartPoint="0,0" EndPoint="1,0"> <GradientBrush.GradientStops> <GradientStopCollection> <GradientStop Color="#FFF" Offset="0.0"/> <GradientStop Color="#CCC" Offset="1.0"/> </GradientStopCollection> </GradientBrush.GradientStops> </LinearGradientBrush> <LinearGradientBrush x:Key="LightBrush" StartPoint="0,0" EndPoint="0,1"> <GradientBrush.GradientStops> <GradientStopCollection> <GradientStop Color="#FFF" Offset="0.0"/> <GradientStop Color="#EEE" Offset="1.0"/> </GradientStopCollection> </GradientBrush.GradientStops> </LinearGradientBrush> <LinearGradientBrush x:Key="HorizontalLightBrush" StartPoint="0,0" EndPoint="1,0"> <GradientBrush.GradientStops> <GradientStopCollection> <GradientStop Color="#FFF" Offset="0.0"/> <GradientStop Color="#EEE" Offset="1.0"/> </GradientStopCollection> </GradientBrush.GradientStops> </LinearGradientBrush> <LinearGradientBrush x:Key="DarkBrush" StartPoint="0,0" EndPoint="0,1"> <GradientBrush.GradientStops> <GradientStopCollection> <GradientStop Color="#FFF" Offset="0.0"/> <GradientStop Color="#AAA" Offset="1.0"/> </GradientStopCollection> </GradientBrush.GradientStops> </LinearGradientBrush> <LinearGradientBrush x:Key="PressedBrush" StartPoint="0,0" EndPoint="0,1"> <GradientBrush.GradientStops> <GradientStopCollection> <GradientStop Color="#BBB" Offset="0.0"/> <GradientStop Color="#EEE" Offset="0.1"/> <GradientStop Color="#EEE" Offset="0.9"/> <GradientStop Color="#FFF" Offset="1.0"/> </GradientStopCollection> </GradientBrush.GradientStops> </LinearGradientBrush> <SolidColorBrush x:Key="DisabledForegroundBrush" Color="#888" /> <SolidColorBrush x:Key="DisabledBackgroundBrush" Color="#EEE" /> <SolidColorBrush x:Key="WindowBackgroundBrush" Color="#FFF" /> <SolidColorBrush x:Key="SelectedBackgroundBrush" Color="#DDD" /> <!-- Border Brushes --> <LinearGradientBrush x:Key="NormalBorderBrush" StartPoint="0,0" EndPoint="0,1"> <GradientBrush.GradientStops> <GradientStopCollection> <GradientStop Color="#CCC" Offset="0.0"/> <GradientStop Color="#444" Offset="1.0"/> </GradientStopCollection> </GradientBrush.GradientStops> </LinearGradientBrush> <LinearGradientBrush x:Key="HorizontalNormalBorderBrush" StartPoint="0,0" EndPoint="1,0"> <GradientBrush.GradientStops> <GradientStopCollection> <GradientStop Color="#CCC" Offset="0.0"/> <GradientStop Color="#444" Offset="1.0"/> </GradientStopCollection> </GradientBrush.GradientStops> </LinearGradientBrush> <LinearGradientBrush x:Key="DefaultedBorderBrush" StartPoint="0,0" EndPoint="0,1"> <GradientBrush.GradientStops> <GradientStopCollection> <GradientStop Color="#777" Offset="0.0"/> <GradientStop Color="#000" Offset="1.0"/> </GradientStopCollection> </GradientBrush.GradientStops> </LinearGradientBrush> <LinearGradientBrush x:Key="PressedBorderBrush" StartPoint="0,0" EndPoint="0,1"> <GradientBrush.GradientStops> <GradientStopCollection> <GradientStop Color="#444" Offset="0.0"/> <GradientStop Color="#888" Offset="1.0"/> </GradientStopCollection> </GradientBrush.GradientStops> </LinearGradientBrush> <!-- Miscellaneous Brushes --> <SolidColorBrush x:Key="GlyphBrush" Color="#FF00FF00" /> <SolidColorBrush x:Key="LightColorBrush" Color="#DDD" />這是單選按鈕樣式，它僅通過IsChecked樣式更改其內容（例如，在您的示例中，如上所述進行了一些小的更改）：
<ImageBrush x:Key="CheckedBullet" ImageSource="MyResources/Koala.jpg"/> <ImageBrush x:Key="UnCheckedBullet" ImageSource="MyResources/Penguins.jpg"/> <Style x:Key="RadioBtnToolStyle" TargetType="{x:Type RadioButton}"> <Setter Property="Background" Value="#00FFFFFF" /> <Setter Property="HorizontalAlignment" Value="Center" /> <Setter Property="Foreground" Value="{x:Null}" /> <Setter Property="Padding" Value="0" /> <Setter Property="Margin" Value="3" /> <Setter Property="BorderBrush" Value="{x:Null}" /> <Setter Property="OverridesDefaultStyle" Value="True" /> <Setter Property="RenderTransform"> <Setter.Value> <ScaleTransform CenterX="30" CenterY="30" ScaleX="1" ScaleY="1" /> </Setter.Value> </Setter> <Setter Property="Cursor" Value="Hand" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="RadioButton"> <Border Name="border" BorderThickness="0" BorderBrush="Black" Background="{TemplateBinding Background}"> <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" /> </Border> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Opacity" Value="0.8" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="IsPressed" Value="True"> <Trigger.EnterActions> <BeginStoryboard> <Storyboard> <DoubleAnimation From="1" To="0.8" AutoReverse="False" Duration="00:00:00.6" Storyboard.TargetProperty="RenderTransform.ScaleX" /> <DoubleAnimation From="1" To="0.8" AutoReverse="False" Duration="00:00:00.6" Storyboard.TargetProperty="RenderTransform.ScaleY" /> </Storyboard> </BeginStoryboard> </Trigger.EnterActions> <Trigger.ExitActions> <BeginStoryboard> <Storyboard> <DoubleAnimation To="1" Duration="00:00:00.6" Storyboard.TargetProperty="RenderTransform.ScaleX" /> <DoubleAnimation To="1" Duration="00:00:00.6" Storyboard.TargetProperty="RenderTransform.ScaleY" /> </Storyboard> </BeginStoryboard> </Trigger.ExitActions> </Trigger> </Style.Triggers> </Style> <!--code that use the style above--> <RadioButton GroupName="Tools" Grid.Row="0" IsChecked="{Binding IsBrightnessAndContrastEnabled, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" HorizontalAlignment="Right" VerticalAlignment="Bottom"> <RadioButton.Style> <Style TargetType="RadioButton" BasedOn="{StaticResource RadioBtnToolStyle}"> <Setter Property="Width" Value="50"></Setter> <Setter Property="Height" Value="50"></Setter> <Style.Triggers> <Trigger Property="IsChecked" Value="True"> <Setter Property="Content" Value="{StaticResource InvertImageBtn}" /> </Trigger> <Trigger Property="IsChecked" Value="False"> <Setter Property="Content" Value="{StaticResource LogoFooterBackgroundStyle}" /> </Trigger> </Style.Triggers> </Style> </RadioButton.Style> </RadioButton>這是可以單獨管理IsChecked狀態的組合（但是您不能以這種方式組合組合和RadioButton）：
