我正在使用以下代码使我的窗体(FormBorderStyle = none)具有圆角边缘:
[DllImport("Gdi32.dll", EntryPoint = "CreateRoundRectRgn")]
private static extern IntPtr CreateRoundRectRgn
(
int nLeftRect, // x-coordinate of upper-left corner
int nTopRect, // y-coordinate of upper-left corner
int nRightRect, // x-coordinate of lower-right corner
int nBottomRect, // y-coordinate of lower-right corner
int nWidthEllipse, // height of ellipse
int nHeightEllipse // width of ellipse
);
public Form1()
{
InitializeComponent();
Region = System.Drawing.Region.FromHrgn(CreateRoundRectRgn(0, 0, Width, Height, 20, 20));
}
并使用以下代码在Paint事件中设置自定义边框:
ControlPaint.DrawBorder(e.Graphics, this.ClientRectangle, Color.Black, 5, ButtonBorderStyle.Solid, Color.Black, 5, ButtonBorderStyle.Solid, Color.Black, 5, ButtonBorderStyle.Solid, Color.Black, 5, ButtonBorderStyle.Solid);
看看这个 .
内部表单矩形没有圆角。
我该如何使蓝色的内部表单矩形也有圆角,这样它就不会像屏幕截图一样了?
