Question

我是XAML和WPF的新手。

按下按钮我想将按钮上绘制的画布从ic_maximize更改为ic_restore，并在再次按下按钮时切换画布。我正在使用mahapps库。你能告诉我怎么做吗？

我尝试了很多不同的StackOverflow链接，但没有一个与我的问题相关。

这是我的最大化按钮的样式。我有＃34; IsPressed＆＃34;触发就绪，但无法确定触发时需要设置的内容.-

<Canvas x:Key="ic_maximize" Width="13.3333" Height="13.3333" Canvas.Left="0" Canvas.Top="0">
    <Rectangle Width="11.7333" Height="11.7333" Canvas.Left="2.136" Canvas.Top="-0.536002" Stretch="Fill" StrokeThickness="1.06667" StrokeLineJoin="Round" Stroke="#FF999999"/>
    <Rectangle Width="11.7333" Height="11.7333" Canvas.Left="5.36442e-007" Canvas.Top="1.6" Stretch="Fill" StrokeThickness="1.06667" StrokeLineJoin="Round" Stroke="#FF999999" Fill="#FF161616"/>
</Canvas>

<Canvas x:Key="ic_restore" Width="12" Height="12" Canvas.Left="0" Canvas.Top="0">
    <Rectangle Width="11.7333" Height="11.7333" Canvas.Left="5.36442e-007" Canvas.Top="0.266666" Stretch="Fill" StrokeThickness="1.06667" StrokeLineJoin="Round" Stroke="#FF999999"/>
</Canvas>

<Style x:Key="ExtendedMaxButtonStyle"
   TargetType="{x:Type Button}"
   BasedOn="{StaticResource MetroWindowButtonStyle}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Grid Name="grid" Background="{StaticResource MaxButton.Grid.background}">
                        <!-- either one of the ic_maximize/ic_restore canvases should come here -->
                </Grid>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsMouseOver" Value="True">
                        <Setter TargetName="grid" Property="Background" Value="{StaticResource MaxButton.MouseOver.Background}" />
                    </Trigger>
                    <Trigger Property="IsPressed" Value="True">
                    <!-- What should I write here?-->
                    </Trigger>
                    <Trigger Property="IsPressed" Value="False">
                     <!-- What should I write here?-->
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

将level_id放在一起，并在static String clock; public static void main(String[] args) { time(); clock = time(); result(); } public static String time() { Calendar cal = new GregorianCalendar(); int Hour = cal.get(Calendar.HOUR_OF_DAY); int Min = cal.get(Calendar.MINUTE); int Sec = cal.get(Calendar.SECOND); String time = Hour + ":" + Min + ":" + Sec; return "[" + time + "]"; }上隐藏一个public static void result() { try { Print("Loading textures"); Thread.sleep(2500); Print("Loading sounds"); Thread.sleep(1500); Print("Loading events"); Thread.sleep(1000); Print("Loaded"); } catch (Exception e) {} }。

func jsonToString(json: AnyObject){
        do {
          let data1 =  try NSJSONSerialization.dataWithJSONObject(json, options: NSJSONWritingOptions.PrettyPrinted) // first of all convert json to the data
            let convertedString = String(data: data1, encoding: NSUTF8StringEncoding) // the data will be converted to the string
            print(convertedString) // <-- here is ur string  

        } catch let myJSONError {
            print(myJSONError)
        }

    }
