如何更改 GroupBox 文本的 ForeColor 而不更改其子 ForeColor? [英] How can I change the ForeColor of the GroupBox text without changing its children ForeColor?

问题描述

我想知道是否有一个选项可以更改窗口窗体中组框左上角的组框文本的颜色，而不是位于组框内的任何控件或标签.

I want to know if there is an option to just change the color of group box text at the top left of the group box in a windows form and not any controls or labels located inside of the group box.

我知道 GroupBox.ForeColor = Color.Blue 会将与该框关联的所有文本更改为蓝色，但它也会更改标签和其他控件的 ForeColorGroupBox.

I know that GroupBox.ForeColor = Color.Blue will change all text associated with that box to blue, but it also changes the ForeColor of labels and other controls in the GroupBox.

如何更改分组框文本的颜色而不更改其子前景色?

推荐答案

ForeColor 属性是一个环境属性.环境属性是一个控件属性，如果未设置，则从父级检索控制.

The ForeColor property is an ambient property. An ambient property is a control property that, if not set, is retrieved from the parent control.

由于您没有为分组框中的标签和文本框设置 ForeColor，它们将使用其父级的 ForeColor 值.您可以使用以下任一选项解决此问题:

Since you didn't set ForeColor for the labels and textboxes in the group box, they will use ForeColor value of their parent. You can solve this problem using either of these options:

1. 在GroupBox中放置一个Panel 将GroupBox的ForeColor设置为Blue 并使用设计器将 Panel 的 ForeColor 显式设置为 ControlText.然后将其他控件放入Panel.这样，您的控件将使用您明确设置的 Panel 的 ForeColor.

1. Put a Panel in GroupBox Set the ForeColor of GroupBox to Blue and set ForeColor of Panel to ControlText explicitly using designer. Then put other controls in the Panel. This way, your controls will use ForeColor of Panel which you set explicitly.

自定义GroupBox的Paint:

Private Sub GroupBox1_Paint(ByVal sender As System.Object, _
    ByVal e As System.Windows.Forms.PaintEventArgs) Handles GroupBox1.Paint

    e.Graphics.Clear(Me.GroupBox1.BackColor)
    GroupBoxRenderer.DrawGroupBox(e.Graphics, Me.GroupBox1.ClientRectangle, _
        Me.GroupBox1.Text, Me.GroupBox1.Font, Color.Blue, _
        System.Windows.Forms.VisualStyles.GroupBoxState.Normal)
End Sub
