Winform自定义窗体样式,实现标题栏可灵活自定义

最近在编写C/S结构应用程序时,感觉窗体的标题栏样式太死板了,标题文字不能更改大小、颜色、字体等,按钮不能隐藏等问题,在网上也查找了许多相关的资料,没有找到合适的解决方案,发现许多人也在寻求这个问题,最后我决定自己研究动手画一个标题栏出来,经过今天一天的研究与编写,终于完成全部功能,现公布一下我的设计思路。

一、去掉Form类自带的标题栏                         

      要去掉自带的标题栏有两种方法,第一方法是直接将FormBorderStyle设为 System.Windows.Forms.FormBorderStyle.None,但设置过后,窗体无法改变大小,考虑到后期这些功能还是需要的,所以我采用了第二种方法,第二种方法是可以忽略FormBorderStyle,只需要将ControlBox设为 false,并将Text设为空即可,这种方法隐藏标题栏,若FormBorderStyle不是固定模式,则可以通过拉伸窗体边框改变大小的。

二、创建自定义窗体类                                     

首先创建一个窗体,如下图:

然后去掉Text默认的文字,并将ControlBox设为 false,此时标题栏将自动隐藏掉了,如下图:

去掉标题栏后,就需要重画新的标题栏,画标题栏很简单,方法也很多,我这里是采用一个Panel,将Dock设为Top,让其项部固定,并设高度为30像素,再在其中添加三个按钮,依次为:button1(关闭),button2(最大化),button3(最小化),三个按钮的设为Size相同,且将Anchor都设为Top Right Bottom,这样就实现了让三个按钮在右边固定位置,如下图:

界面部份已经完工,剩下的就是编写代码了,由于代码较多,我先将代码贴出来,稍后再讲解。

代码中FormBorderStyle覆盖父类的同名属性,主要是实现根据不同的窗体,能够自动调整标题栏按钮,因为当FormBorderStyle为FormBorderStyle.Sizable或FormBorderStyle.SizableToolWindow时,才需要最大化按钮,否则都是不需要的。不需要的情况下,将移除最大化按钮对象button2,

titlepanel.Controls.Remove(button2);

由于隐藏自带的标题栏需要确保Text属性为空,ControlBox为False,所以我这里采取了重写这两个属性,并加上Browsable(false),让其在编辑器中不可见。

Title,TitleFont,TitleColor,TitleBarBackColor为新增自定义属性,分别用于设置标题文字,标题文字样式,标题文字颜色,标题栏背景色。

重写MaximizeBox与MinimizeBox两个属性,使其根据设为True与False时,能相应的调整标题栏按钮。

私有方法:ResetTitlePanel,用于重设标题栏按钮属性。

方法Titlebutton_Click这个简单,主要用于实现标题栏上三个按钮点击时所要执行的操作。

Titlepanel_MouseDown,Titlepanel_MouseUp ,Titlepanel_MouseMove 三个方法是用于实现点击鼠标右键并按住移动就能够移动窗体,Titlepanel_DoubleClick方法是实现双击时能够最大化或还原窗体功能。

最后的titlepanel_ControlRemoved与titlepanel_ControlAdded,实现的功能是当增加或移除按钮时,调整按钮的位置。

三、使用自定义窗体类                                     

使用就比较简单了,先是新增一个窗体,然后将窗体类的父类由Form改为自定义窗体类(ZForm)即可,然后再切换到设计视图页面,是不是发现界面已经变化了呢,这时候就可以依据的想法灵活设置窗体标题栏样式,如下图:

    public partial class Form1 : ZControls.ZForm
    {
        public Form1()
        {
            InitializeComponent();
        }
    }

将MaximizeBox设为False时,运行的效果,是不是有点爽啊!
