2.实例

(2)Form1.Designer.cs设计

(3)Form1.cs设计

(4) 生成效果

(5)一个遗憾


1.窗体更换皮肤

        要在Windows窗体应用程序中更换皮肤,通常需要修改窗体的外观,包括其颜色、字体、鼠标光标和非客户区(如窗口边框、最小化和最大化按钮等)。这可以通过创建一个自定义窗体或使用第三方库来实现。

2.实例

        在本实例的自定义窗体中单击鼠标右键,将弹出一个用于更换窗体皮肤的快捷菜单,选择“换皮肤”菜单下的任意子菜单:紫色、蓝色或绿色,程序将为当前窗体更换皮肤。

(1)图片资源管理器Resources.Designer.cs设计

        项目之初,先为项目准备好皮肤所需要的图片资源,并把图片设计到Resources.Designer.cs中,具体的设计方法参考本文作者写的其他文章:C#手动改变自制窗体的大小-CSDN博客 https://wenchm.blog.csdn.net/article/details/137027140

(2)Form1.Designer.cs设计

         开始窗体设计,自定义窗体承载皮肤图片的panel控件设计,最小化、最大化、关闭,menuStrip1菜单设计,最重要的用于更换皮肤的ContextMenuStrip控件。

        在C#中,ContextMenuStrip控件是用于显示右键菜单的,而ToolStripMenuItem是该菜单中的一个项目。 对于ContextMenuStrip的DropDownItems,它们实际上是ToolStripItem的子类。设计三个ToolStripMenuItem菜单,用于切换不同的皮肤。

        所有控件的方法,都在这里设计。这个实例不仅仅能换肤,还能实现窗体最小化、最大化、关闭、鼠标拖动各个边框改变窗体大小;鼠标拖动左下角、右下角同时改变窗体的长和宽;

(5)一个遗憾

         本实例有一个缺点,就是窗体左上角显示的切换后的皮肤名称(toolStripMenuItem9、10、11)会随着窗体最大化而被拉伸,字体扭曲了,很难看。我没有解决掉也没时间去解决。有兴趣的网友一旦解决了这个缺陷,请贴出来你用好点子。
