Question

大家好我想用C＃WPF构建一个科学的计算器。

我想要做的是通过调整UI大小小于或大于特定大小（具有特定宽度和高度）来将表单从简单计算器更改为科学计算器。

是否有关于此功能的文章或示例？

非常感谢。

我想指出我的想法：

就像iPhone上的计算器一样，当我旋转屏幕时，计算器将处于科学模式，因此当我拖动调整计算器大小时，这就是我想要的Windows程序，模式将会改变。

代码隐藏

public partial class MainWindow : Window

        public MainWindow()
        {
            InitializeComponent();
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            sinBtn.Visibility = Visibility.Visible;
            cosBtn.Visibility = Visibility.Visible;
            logBtn.Visibility = Visibility.Visible;
            eBtn.Visibility = Visibility.Visible;
        }
    }

这个可能会被标记，因为它不是很清楚你在问什么。如果我理解了问题，那么您需要从窗口中删除宽度和高度参数，并设置int i = 0; while(inFile) { numbers[i] += num; i++; inFile >> num; }，WindowStyle和SizeToContent：

ResizeMode

结果是一个自动调整内容大小的窗口，无法调整大小：

更新：

哦，好吧，那是非常不同的:)实际上有很多方法可以做到这一点，我将提供一个不做MVVM或其他任何事情的简单方法。您需要做的是在窗口的资源部分添加控制模板，每个模式一个，子控件显示它们：

<Window x:Class="GuiTest.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Calculator"
    WindowStyle="SingleBorderWindow"
    SizeToContent="WidthAndHeight"
    ResizeMode="NoResize" FontSize="20">

<StackPanel Orientation="Vertical">
    <Border BorderBrush="Black" BorderThickness="1" Background="LightGray" HorizontalAlignment="Stretch" Height="60" Margin="5" >
        <TextBlock Text="0" TextAlignment="Right" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Padding="5" FontSize="40" />
    </Border>
    <UniformGrid Columns="4">
        <UniformGrid.Resources>
            <Style TargetType="Button" >
                <Setter Property="Margin" Value="5" />
                <Setter Property="Width" Value="60" />
                <Setter Property="Height" Value="60" />
            </Style>
        </UniformGrid.Resources>
        <Button Content="CE" />
        <Button Content="C" />
        <Button Content="&lt;" />
        <Button Content="÷" />
        <Button Content="7" />
        <Button Content="8" />
        <Button Content="9" />
        <Button Content="x" />
        <Button Content="4" />
        <Button Content="5" />
        <Button Content="6" />
        <Button Content="-" />
        <Button Content="1" />
        <Button Content="2" />
        <Button Content="3" />
        <Button Content="+" />
        <Button Content="±" />
        <Button Content="0" />
        <Button Content="." />
        <Button Content="=" />
    </UniformGrid>
</StackPanel>

然后你需要添加一个查看新大小的<Window.Resources> <ControlTemplate x:Key="Standard"> <TextBlock Text="Standard Mode" /> </ControlTemplate> <ControlTemplate x:Key="Scientific"> <TextBlock Text="Scientific Mode" /> </ControlTemplate> </Window.Resources> <ContentControl x:Name="myPanel" />处理程序，并为要使用的控件选择合适的模板：

SizeChanged

拖动窗口，您会相应地看到控件的外观发生变化。

我理解你的问题，

您希望以单一形式显示简单科学的计算器。并且会有一些选项..说按钮..这将关闭/关闭科学计算到简单计算。

所以创建两个面板..

面板1＆gt;＆gt;保持所有简单的calc控制面板2＆gt;保持所有科学控制。

当您点击按钮打开/关闭简单/科学计算..

按一下按钮点击事件并隐藏一个面板并相应地显示其他面板。并相应调整窗口大小，

 execute Check_Name 'Pope', 'Life2Stressfull';

按钮点击事件使用：

 <WrapPanel Name="simple" Height="300" Width="300" >
        <StackPanel>
            <Button Content="1" Height="23" Name="button1" Width="40" />
            <Button Content="4" Height="23" Name="button4" Width="40" />
            <Button Content="7" Height="23" Name="button7" Width="40" />
        </StackPanel>
        <StackPanel>
            <Button Content="2" Height="23" Name="button2" Width="40" />
            <Button Content="5" Height="23" Name="button5" Width="40" />
            <Button Content="8" Height="23" Name="button8" Width="40" />
        </StackPanel>
    </WrapPanel>
    <WrapPanel Name="scientific" Height="300" Width="500" >
        <StackPanel>
            <Button Content="1" Height="23" Name="sbutton1" Width="40" />
            <Button Content="4" Height="23" Name="sbutton4" Width="40" />
            <Button Content="7" Height="23" Name="sbutton7" Width="40" />
        </StackPanel>
        <StackPanel>
            <Button Content="2" Height="23" Name="sbutton2" Width="40" />
            <Button Content="5" Height="23" Name="sbutton5" Width="40" />
            <Button Content="8" Height="23" Name="sbutton8" Width="40" />
        </StackPanel>
        <StackPanel>
            <some more controls...>
        </StackPanel>
    </WrapPanel>

反之亦然

如何在调整大小小于或大于特定宽度和高度时更改表单？
