.NET 解决TabControl 页里面多余边距问题经验分享
2014-08-29来源:

以下是解决方法:

1.直接新建一个类,继承TabControl,然后 override DisplayRectangle 方法:

复制代码代码如下:

/// <summary>

/// 解决系统TabControl多余边距问题

/// </summary>

public class FullTabControl : TabControl {

public override Rectangle DisplayRectangle {

get {

Rectangle rect = base.DisplayRectangle;

return new Rectangle(rect.Left - 4, rect.Top - 4, rect.Width + 8, rect.Height + 7);

}

}

}

以后用 FullTabControl 就行。(这种方法简单)

2.参见以下网址(VB.NET)代码:

C# 代码为:

复制代码代码如下:

public class FullTabControl : NativeWindow {

static int TCM_FIRST = 0x1300;

static int TCM_ADJUSTRECT = (TCM_FIRST + 40);

struct RECT{

public int Left, Top, Right, Bottom;

}

protected override void WndProc(ref Message m) {

if (m.Msg == TCM_ADJUSTRECT) {

RECT rc = (RECT)m.GetLParam(typeof(RECT));

rc.Left -= 4;

rc.Right += 3;

rc.Top -= 4;

rc.Bottom += 3;

Marshal.StructureToPtr(rc, m.LParam, true);

}

base.WndProc(ref m);

}

}

调用方法:new FullTabControl().AssignHandle(tabControl1.Handle);// tabControl1为窗口上TabControl控件的名称
