Question

我是WPF的新人，请记住这一点。我正在尝试让窗口响应调整大小，textboxes和buttons等控件是否可能随着窗口的增大或缩小而调整大小？

<Window x:Class="WPF_Working_Experimenet.Window1"

            <ColumnDefinition Width="295*"/>
        </Grid.ColumnDefinitions>

        <Button x:Name="btnExit" Content="Exit" HorizontalAlignment="Left" VerticalAlignment="Top" Width="60" Grid.Column="1" Margin="146,103,0,0" Height="37" Background="#FFFDFDFD" BorderBrush="Red" Click="Button_btnExit" FontFamily="B Nazanin" FontSize="15"/>

任何Reference/hint或Tutorial/link都很可爱。提前谢谢你

Answer 1

如果您希望控件增长/缩小，则必须设置边距/填充而不是显式宽度/高度。

很少有链接可以帮助您：

Answer 2

如果您明确设置#include <iostream> #include <cstring> #include <string> #include <cctype> using namespace std; int vowels(string s, int L) { int sum = 0; char str[s.length()-1]; strcpy(str,s.c_str()); if(str[L]) { tolower(str[L]); if(str[L]!='a'||str[L]!='e'||str[L]!='i'||str[L]!='o'||str[L]!='u') sum = 0; else sum = 1; return sum += vowels(s,L++); } else return 0; }和Width属性，则不会调整控件大小。请尝试以下操作，我删除了Height和Width属性，并将Height和HorizontalAlignment值更改为VerticalAlignment。

        <ColumnDefinition />

        <ColumnDefinition />

    </Grid.ColumnDefinitions>
    <Image Source="View/Images/LoginImg.jpg" Stretch="Fill" Grid.Column="0" Grid.ColumnSpan="3">

                <TranslateTransform/>
            </TransformGroup>
        </Canvas.RenderTransform>
        <Label Content="Login" VerticalContentAlignment="Stretch" HorizontalContentAlignment="Stretch" Background="BurlyWood" FontSize="15" Height="52" Width="254">
            <Label.FontWeight>Bold</Label.FontWeight>

        <TextBox Height="24" Canvas.Left="20" TextWrapping="Wrap" Text="User Name" TextAlignment="Center" Canvas.Top="84" Width="120" Foreground="Gray"/>
        <PasswordBox Canvas.Left="20" Canvas.Top="136" Height="34" Width="120"/>
    </Canvas>
</Grid>

将水平和垂直对齐方式设置为拉伸，而不是设置小部件的宽度和高度即可解决问题。但是仍然可以根据需要设置边距。进行了尝试，并确保在更改窗口大小时，小部件将分别进行调整。
