我是WPF的初學者,必須爲某人的用戶界面添加功能。這是代碼的一部分。如何獲取邊界的邊界值?
<Border BorderBrush="Black" BorderThickness="1" Grid.Row="1" >
<Grid Grid.Row="0">
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition Width="{Binding ElementName=passFailIndicator, Path=Width}"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Border Background="Black" local:StretchPanel.Proportion="1" Name="imageBorder" Grid.Column="0">
<Border BorderThickness="1" Margin="2" BorderBrush="Green" HorizontalAlignment="Left" VerticalAlignment="Top" Width="{Binding ElementName=imageBorder, Path=Width}">
<Grid Width="{Binding ElementName=imageBorder, Path=Width}">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="{Binding ElementName=imageSelectExpander, Path=Width}"/>
</Grid.ColumnDefinitions>
<Image Grid.Column="0" x:Name="image" Source="{Binding DisplayImage, Mode=OneWay}" VerticalAlignment="Top" Stretch="Uniform" HorizontalAlignment="Left" StretchDirection="Both" MouseMove="image_MouseMove" />
<TextBlock Name="pxPos" Text="mouse position" HorizontalAlignment="Right" VerticalAlignment="Bottom" MaxHeight="20" Foreground="Aqua"></TextBlock>
<Expander Grid.Column="1" VerticalAlignment="Top" Name="imageSelectExpander">
<ComboBox x:Name="imageSelect" ItemsSource="{Binding AvailableImages, Mode=OneWay}" SelectedIndex="{Binding ImageSelect, Mode=TwoWay}" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Margin="4" Padding="4" MaxHeight="40"></ComboBox>
</Expander>
</Grid>
</Border>
</Border>
<Border x:Name="passFailIndicator" Grid.Column="1" HorizontalAlignment="Left" VerticalAlignment="Center" Width="100" Height="100">
<Viewbox Stretch="Uniform" >
<Path Style="{Binding TestResult, Mode=OneWay, Converter={StaticResource testResultToPathStyle}}" Margin="2" />
</Viewbox>
</Border>
</Grid>
</Border>
我試圖訪問線10分的保證金=「2」當我使用this.imageBorder.Margin,我得到{0,0,0,0}。我將如何獲得2(當然,這個值可能會改變)?
感謝
編輯:
FrameworkElement fe = (FrameworkElement)this.imageBorder.Child;
pxPos.Text = (string.Format("x:{0} y:{1}", (int)((double)(pt.X - fe.Margin.Left) * (double)this.image.Source.Width/this.image.ActualWidth), (int)((double)(pt.Y - fe.Margin.Top)*(double)this.image.Source.Height/this.image.ActualHeight)));
謝謝,我會明確寫下代碼以防其他人一天尋找它 – Denis
