これは遅い回答ですが、うまくいけば誰かがそれから恩恵を受けるでしょう、以下は私がTabPageで画像をアニメートするために行ったことです、アニメーション化されたローディングアイコンを表示するために使用しました。それらをリソースに含めました。
using System;
using System.Windows.Forms;
using System.Drawing;
using System.Threading;
namespace GuiLib
{
public class AnimatedTabControl : TabControl
{
static int ITEM_WIDTH = 250;
static int ITEM_HEIGHT = 25;
static int TIMER_INTERVAL = 80;
static int ICON_X = 3;
static int ICON_Y = 3;
static int ICON_WIDTH = 15;
static int ICON_HIGHT = 15;
static int TEXT_X = 50;
static int TEXT_Y = 6;
static int TEXT_WIDTH = 200;
static int TEXT_HIGHT = 15;
int animationIndex;
static System.Windows.Forms.Timer myTimer = new System.Windows.Forms.Timer();
Bitmap[] animationImages = {new Bitmap(GuiLib.Properties.Resources._0), new Bitmap(GuiLib.Properties.Resources._1),new Bitmap(GuiLib.Properties.Resources._2),
new Bitmap(GuiLib.Properties.Resources._3),new Bitmap(GuiLib.Properties.Resources._4),new Bitmap(GuiLib.Properties.Resources._5),
new Bitmap(GuiLib.Properties.Resources._6),new Bitmap(GuiLib.Properties.Resources._7)};
Bitmap animatedimage;
public AnimatedTabControl()
: base()
{
this.DrawMode = TabDrawMode.OwnerDrawFixed;
this.SizeMode = TabSizeMode.Fixed;
this.ItemSize = new Size(ITEM_WIDTH, ITEM_HEIGHT);
myTimer.Tick += new EventHandler(TimerEventProcessor);
myTimer.Interval = TIMER_INTERVAL;
animationIndex = 0;
}
private void TimerEventProcessor(Object myObject, EventArgs myEventArgs)
{
animationIndex++;
if (animationIndex >= animationImages.Length)
animationIndex = 0;
animatedimage = animationImages[animationIndex];
AnimateLoadingTabsOrStopIfNonIsLoading();
}
private void AnimateLoadingTabsOrStopIfNonIsLoading()
{
bool stopRunning = true;
for (int i = 0; i < this.TabPages.Count; i++)
{
if (this.TabPages[i] is LoadingTabPage)
{
LoadingTabPage ltp = (LoadingTabPage)this.TabPages[i];
if (ltp.Loading)
{
stopRunning = false;
Rectangle r = GetTabRect(i);
this.Invalidate(new Rectangle(r.X + ICON_X, r.Y + ICON_Y, ICON_WIDTH, ICON_HIGHT));
}
}
}
if (stopRunning)
myTimer.Stop();
}
protected override void OnDrawItem(DrawItemEventArgs e)
{
Rectangle r = e.Bounds;
r = GetTabRect(e.Index);
DrawAnimationImageIfLoading(e, r);
DrawTabTitle(e, r);
}
private void DrawTabTitle(DrawItemEventArgs e, Rectangle r)
{
string title = this.TabPages[e.Index].Text;
StringFormat titleFormat = new StringFormat();
titleFormat.Trimming = StringTrimming.EllipsisCharacter;
e.Graphics.DrawString(title, this.Font, Brushes.Black, new RectangleF(r.X + TEXT_X, r.Y + TEXT_Y, TEXT_WIDTH, TEXT_HIGHT), titleFormat);
}
private void DrawAnimationImageIfLoading(DrawItemEventArgs e, Rectangle r)
{
if (this.TabPages[e.Index] is LoadingTabPage)
{
if (((LoadingTabPage)this.TabPages[e.Index]).Loading)
{
if (animatedimage != null)
e.Graphics.DrawImage(animatedimage, new RectangleF(r.X + ICON_X, r.Y + ICON_Y, ICON_WIDTH, ICON_HIGHT));
if (!myTimer.Enabled)
myTimer.Start();
}
}
}
}
}
そして、このようLoadingTabPage
:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace GuiLib
{
/// <summary>
/// A Class to facilitate tab page with animated loading icon.
/// </summary>
public class LoadingTabPage : TabPage
{
public LoadingTabPage(string s)
: base(s)
{
loading = false;
}
public LoadingTabPage()
: base()
{
loading = false;
}
private bool loading;
public bool Loading
{
get { return loading; }
set
{
loading = value;
if (this.Parent != null)
{
this.Parent.Invalidate();
}
}
}
}
}
使い方は簡単になります:私が思ったよう
myLoadingTabPage.Loading = true;
は、唯一の解決策は、オーナー描画にあります。しかし、参照コードを取得することは良いことであり、将来誰かを助けることを願っています。 –
