如何制作自定义按钮？ [英] How do I make a custom button?

问题描述

大家好。我正在尝试制作一个实际上是标签的自定义按钮。

我有两个问题。当鼠标进入控件时我无法重绘。我无法在设计器中更改PaintBackColor，HoverBackColor和BorderColor属性的属性。以下是我目前的代码..

Hi all. I am trying to make a custom button which is a label actually.
I have two issues. I cannot repaint when mouse enters control AND I cannot change the property of the PaintBackColor, HoverBackColor And BorderColor properties in the designer. Here is the code I currently have..

Public Class PlayButton : Inherits Label
    Public Property PaintBackColor As Brush
    Public Property HoverBackColor As Brush
    Public Property BorderColor As Brush
    Public Property BorderSize As Single
    Protected Overrides Sub OnPaint(ByVal pevent As System.Windows.Forms.PaintEventArgs)
        TextAlign = ContentAlignment.MiddleCenter
        FlatStyle = Windows.Forms.FlatStyle.Flat
        BackColor = Color.Transparent
        AutoSize = False
        Dim OutPen As Pen = New Pen(BorderColor, BorderSize)
        pevent.Graphics.DrawEllipse(OutPen, 0, 0, Width, Height)
        pevent.Graphics.FillEllipse(PaintBackColor, 0, 0, Width, Height)
        MyBase.OnPaint(pevent)
    End Sub

    Protected Overrides Sub OnMouseEnter(ByVal e As System.EventArgs)
    End Sub
End Class

提前谢谢，

推荐答案

请参阅我对该问题的评论。你什么也没做。你需要处理很多事件，特别是 MouseEnter 和 MouseLeave ：

https://msdn.microsoft.com/en -us / library / system.windows.forms.control.mouseenter（v = vs.110）.aspx [ ^ ]，

https://msdn.microsoft.com/en-us/ library / system.windows.forms.control.mouseleave（v = vs.110）.aspx [ ^ ]。



通过无效实现重新绘画：

Please see my comment to the question. You do next to nothing. You need to handle many events, in particular, MouseEnter and MouseLeave:
https://msdn.microsoft.com/en-us/library/system.windows.forms.control.mouseenter(v=vs.110).aspx[^],
https://msdn.microsoft.com/en-us/library/system.windows.forms.control.mouseleave(v=vs.110).aspx[^].

Re-painting is achieved by invalidation:
https://msdn.microsoft.com/en-us/library/598t492a(v=vs.110).aspx[^],
https://msdn.microsoft.com/en-us/library/xz8ytzt0(v=vs.110).aspx[^],
https://msdn.microsoft.com/en-us/library/8dtk06x2(v=vs.110).aspx[^],
https://msdn.microsoft.com/en-us/library/wtzka3b5(v=vs.110).aspx[^],
https://msdn.microsoft.com/en-us/library/8bk29t0f(v=vs.110).aspx[^],
