c# - 如何更改所有控件的 MetroFramework 样式颜色

Question

我正在使用MetroFramework在我的桌面应用程序中，并将所有主题颜色广告设置为默认值，同时在父表单中进行更改，我想更新所有子表单并控制颜色作为标准主题颜色。

检查设计 UI

更改主题

var m = new Random();
int next = m.Next(0, 13);
this.Style = (MetroColorStyle)next;

通过该操作，主窗体颜色发生变化，但 Controller 和子窗体样式颜色没有变化。

嗨，苏尼尔，

示例-1在MetroStyleManager工具箱中添加

示例2(扩展方法)

    public static void SetDefaultStyle(this IContainer contr, MetroForm owner, MetroColorStyle style)
    {
        MetroStyleManager manager = FindManager(contr, owner);
        manager.Style = style;
    }
    public static void SetDefaultTheme(this IContainer contr, MetroForm owner, MetroThemeStyle thme)
    {
        MetroStyleManager manager = FindManager(contr, owner);
        manager.Theme = thme;
    }
    private static MetroStyleManager FindManager(IContainer contr, MetroForm owner)
    {
        MetroStyleManager manager = new MetroStyleManager(contr);
        foreach (IComponent item in contr.Components)
        {
            if (((MetroStyleManager)item).Owner == owner)
            {
                 manager = (MetroStyleManager)item;
            }
        }
        return manager;
    }

使用:

    public frmMain()
    {
        InitializeComponent();            
        this.components.SetDefaultStyle(this, MetroColorStyle.Purple);
    }

示例 - 3:如果您想为所有表单设置主题。

第 1 步:创建新类“MyExtensions.cs”。这是内容:

public static class MyExtensions
{
    //What is your style
    private const MetroColorStyle FormStyle = MetroColorStyle.Green;
    public static void SetStyle(this IContainer container, MetroForm ownerForm)
    {
        if (container == null)
        {
            container = new System.ComponentModel.Container();
        }
        var manager = new MetroFramework.Components.MetroStyleManager(container);
        manager.Owner = ownerForm;
        container.SetDefaultStyle(ownerForm, FormStyle);


    }
    public static void SetDefaultStyle(this IContainer contr, MetroForm owner, MetroColorStyle style)
    {
        MetroStyleManager manager = FindManager(contr, owner);
        manager.Style = style;
        owner.Style = style;
    }
    public static void SetDefaultTheme(this IContainer contr, MetroForm owner, MetroThemeStyle thme)
    {
        MetroStyleManager manager = FindManager(contr, owner);
        manager.Theme = thme;
    }
    private static MetroStyleManager FindManager(IContainer contr, MetroForm owner)
    {
        MetroStyleManager manager = null;
        foreach (IComponent item in contr.Components)
        {
            if (((MetroStyleManager)item).Owner == owner)
            {
                manager = (MetroStyleManager)item;
            }
        }
        return manager;
    }
}

第 2 步:在所有表单中，您都需要调用“Load”方法中的下级方法。示例 Form1.cs 的

private void Form1_Load(object sender, EventArgs e)
{
    this.components.SetStyle(this);
}
