TabControl 의 각 TabPage 에 버튼이 필요할 때가 있다.
각 TabPage 에 버튼을 넣을려면
TabControl 의 OnDrawItem 메소드를 override 하여
일일이 헤더 문자열 하고 버튼을 위치 간격 다 계산해서 우리의 Graphics g 로 다 그려줘야 한다.
그리고 찾아보면 은근 소스도 쉽게 찾을 수 있다.
하지만 만약 TabPage 마다 버튼 갯수도 다르고 버튼마다 아이콘도 맘대로 넣고 헤더 문자열도 변경할 수 있고
덤으로 Drag&Drop 으로 순서까지 변경하게 해달라고 하면 약간 골치 아퍼진다.
그래서 이 소스 저 소스를 버무려봤다.
우선 쉽게 버튼에 대한 정보를 저장하고 넘길 때 사용할 아이가 필요하다.
using System.Drawing;
public class BtnTabPageInfo
{
private int mId = -1;
private Image mEnable = null;
private Image mDisable = null;
/// <summary>
/// 버튼을 구분할 ID
/// </summary>
public int Id
{
get { return this.mId; }
}
/// <summary>
/// 활성시 표시될 버튼 이미지
/// </summary>
public Image Enable
{
get { return this.mEnable; }
}
/// <summary>
/// 비활성시 표시될 버튼 이미지
/// </summary>
public Image Disable
{
get { return this.mDisable; }
}
public BtnTabPageInfo(int Id, Image Enable, Image Disable)
{
this.mId = Id;
this.mEnable = Enable;
this.mDisable = Disable;
}
}
그리고 TabPage 를 상속받고
버튼에 대한 정보 및 헤더 문자열에 대한 수정 여부를 저장할 수 있게 하고
using System.Collections.Generic;
using System.ComponentModel;
using System.Windows.Forms;
public partial class BtnTabPage : System.Windows.Forms.TabPage
{
#region Declare Field
private List<BtnTabPageInfo> mItmes = null;

{
Ctrl.Dock = DockStyle.Fill;
this.Controls.Add(Ctrl);
}
public BtnTabPage(IContainer container)
{

InitializeComponent();

}

{
this.mItmes = null;
}

if (this.mItmes != null)
this.mItmes.Clear();
while (this.Controls.Count > 0)

ctrl.Dispose();
this.Controls.Remove(ctrl);
}
this.Controls.Clear();
}
#endregion
#region Method
public void AddTabItem(BtnTabPageInfo Item)
{
this.mItmes.Add(Item);
this.Text = GetTabHeader(this.Text);
}
public string GetTabHeader(string HeaderText)

if (this.mItmes != null && this.mItmes.Count > 0)
sResult += "".PadRight(6 * this.mItmes.Count, ' ');
return sResult;

}
그리고 젤 중요한 TabControl 을 상속받아서 대충 이렇게 저렇게
메소드들 재정의해서 잘 그려주고 옮겨주면 된다.

그리고 대충 요런식으로 사용해주면

this.btnTabControl1.TabItemClicked += btnTabControl1_TabItemClicked;
this.btnTabControl1.TabRename += btnTabControl1_TabRename;
BtnTabPage tTabPage1 = new BtnTabPage();
tTabPage1.Text = "TabPage1";
tTabPage1.AllowTabEdit = true; // TabPage Header 편집기능 활성화

tTabPage1.AddTabItem(new BtnTabPageInfo(0, Properties.Resources.Navigation_Next_32x32_Regular, Properties.Resources.Navigation_Next_32x32_Disabled));
tTabPage1.AddTabItem(new BtnTabPageInfo(1, Properties.Resources.Navigation_Previous_32x32_Regular, Properties.Resources.Navigation_Previous_32x32_Disabled));
BtnTabPage tTabPage2 = new BtnTabPage();
tTabPage2.Text = "TabPage2";
tTabPage2.AllowTabEdit = true; // TabPage Header 편집기능 활성화
tTabPage2.Controls.Add(new TextBox { Dock = DockStyle.Fill, Multiline = true });
tTabPage2.AddTabItem(new BtnTabPageInfo(0, Properties.Resources.Navigation_Next_32x32_Regular, Properties.Resources.Navigation_Next_32x32_Disabled));
tTabPage2.AddTabItem(new BtnTabPageInfo(1, Properties.Resources.Navigation_Previous_32x32_Regular, Properties.Resources.Navigation_Previous_32x32_Disabled));
btnTabControl1.TabPages.Add(tTabPage1);
btnTabControl1.TabPages.Add(tTabPage2);
....
void btnTabControl1_TabRename(object sender, int SelectedTabIndex)
{
MessageBox.Show("헤더 변경");
}
void btnTabControl1_TabItemClicked(object sender, int SelectedTabIndex, int ButtonID)
{
MessageBox.Show("버튼 클릭 : ID " + ButtonID.ToString());
}
이런식으로 버튼이 나오게 되고 버튼을 누르면 설정한 ID 를 통해서 기능을 분기할 수 있다.
