Tabcontrol，vb.net，选项卡按钮鼠标悬停样式

发布于 2024-12-06 03:37:56 字数 222 浏览 1 评论 0原文

我有一个带有 tabcontrol 的 vb.net windows 窗体项目。

有人知道当您将指针悬停在标签页标题或“按钮”上时如何更改其样式吗？

我想您可以通过以下方式更改颜色：

TabControl1.SelectedTab.BackColor = Color.Black

但不确定如何将鼠标悬停到悬停在选项卡标题/按钮上。

I have a vb.net windows forms project with a tabcontrol.

Anyone know how to change the style of the tabpage title or "button" when you hover over it with the pointer ?

I guess you can change the colours with:

TabControl1.SelectedTab.BackColor = Color.Black

But not sure how to hook up the mouseover to the hovered over tab title/button.

如果您想更改选项卡页（即带有选项卡内容的区域）的颜色，很容易做到，如下所示。

但是，如果要更改选项卡按钮，则需要将 TabControl1 DrawMode 设置为 TabDrawMode.OwnerDrawFixed，然后处理 DrawItem 事件。

Public Class Form1


      Private Sub TabControl1_MouseEnter(sender As System.Object, e As System.EventArgs) Handles TabControl1.MouseEnter
        TabControl1.SelectedTab.BackColor = Color.Black
      End Sub

      Private Sub TabControl1_MouseLeave(sender As System.Object, e As System.EventArgs) Handles TabControl1.MouseLeave
        TabControl1.SelectedTab.BackColor = DefaultBackColor
      End Sub
    End Class

If you want to change color of the tab page (i.e. area with tab content), it is very easy to do as shown below.

However, if you want to change tab button, then you need to set TabControl1 DrawMode to TabDrawMode.OwnerDrawFixed and then handle DrawItem event.

Public Class Form1


      Private Sub TabControl1_MouseEnter(sender As System.Object, e As System.EventArgs) Handles TabControl1.MouseEnter
        TabControl1.SelectedTab.BackColor = Color.Black
      End Sub

      Private Sub TabControl1_MouseLeave(sender As System.Object, e As System.EventArgs) Handles TabControl1.MouseLeave
        TabControl1.SelectedTab.BackColor = DefaultBackColor
      End Sub
    End Class
