以前,程序员在DOS平台下开发应用软件时,都会利用DOS的开放性特点,通过中断编写出一些非凡的显示效果,以此来给自己的程序增加一些有趣的特色。
然而,随着面向Windows的编程和可视化的第四代开发工具的逐步使用,人们越来越被Windows的统一的编程风格所束缚,同时由于Windows直接治理中断,想用原来的方法来实现一些非凡的显示效果变得越来越困难了。
那么,在Windows时代程序员如何来实现窗口的非凡效果呢?实际上,由于整个Windows是图形显示系统,因此对系统而言,用户程序的每一个界面、窗口都是系统的一个画布。程序员可以利用这一特点来实现窗口的非凡效果。
最近笔者利用C++ Builder 5.0 EnterPRise成功的实现了该项功能,现介绍如下:
1、在BCB中建立一个工程文件project1.dpr,在Form1中添加如下控件:
控件名称 属性 值
TForm Color clBTnText
TMainMenu NameMainMneu1
TImage Name Image1
Align alClient
AutoSize True
同时在 MainMenu1控件中增加一个菜单项,其属性为:
Name Caption
Items1 图像从中间往左右分出
Items2 图像从左右往中间合进
Items3 图像从中间往上下分出
Items4 图像从上下往中间合进
Items5 图像从左移入
Items6 图像从右移入
Items7 图像从上移入
Items8 图像从下移入
Items9 图像从左刷屏显示
Items10图像从右刷屏显示
Items11图像从上刷屏显示
Items12图像从下刷屏显示
Items13图像从上往下流水
Items14图像从下往上流水
Items15图像圆形展出
Items16图像左右错移
Items17图像上下错移
同时在Unit.cpp中的private中添加如下变量:
private:
BITMAP bm;
Graphics::TBitmap *Bitmap1;
int i,j;
int WideHalf;
TRect Dest1,Source1,Dest2,Source2;
int HeightHalf;
HRGN MyRgn;
2、在Form1的OnCreate事件中添加如下代码:
void __fastcall TForm1::FormCreate(TObject *Sender)//进行图像特效显示的初始化操作//
{
Graphics::TBitmap *Bitmap1 = new Graphics::TBitmap();//定义一个图象句柄//
Bitmap1-LoadFromFile("C:\\factory.bmp");//设定所要特效显示的图象为factory.bmp//
if(GetDeviceCaps(Form1-Canvas-Handle,BITSPIXEL)==8)//取得显示窗口的颜色属性//
{
GetObject(Bitmap1-Handle,sizeof(BITMAP),(LPSTR)&bm);
if (bm.bmBitsPixel==8)//假如特效显示的图象颜色属性为256色//
{
SelectPalette(Form1-Canvas-Handle,Bitmap1-Palette,FALSE);//从特效显示的颜色画板中提取配色方案//
RealizePalette(Form1-Canvas-Handle); //在显示窗口中设置配色方案//
}
Bitmap-HandleType=bmDDB;
}
}
3、在Items1的OnClieck事件中添加如下代码:
void__fastcall TForm1::Item1Click(TObject *Sender)
{//图象从中间往左右分出//
Form1-Refresh( );
WideHalf=Bitmap1-Width/2+Bitmap1-Width%2;
for(i=0;i
{
Dest1=Rect(WideHalf-i,0,WideHalf+i,Bitmap1-Height);
Source1=Rect(WideHalf-i,0,WideHalf+i,Bitmap1-Height);
Form1-Canvas-CopyRect(Dest1,Bitmap1-Canvas,Source1);
for(j=0;j
}
}
4、在Items2的OnClieck事件中添加如下代码:
void__fastcall TForm1::Item2Click(TObject *Sender)
{ //图像从左右往中间合进//
Form1-Refresh( );
WideHalf=Bitmap1-Width/2+Bitmap1-Width%2;
Form1-Refresh( );
for(i=0;i
{
Source1=Dest1=Rect(0,0,i,Bitmap1-Height);
Source2=Dest2=Rect(Bitmap1-Width-i,0,Bitmap-Width,Bitmap1-Height);
Form1-Canvas-CopyRect(Dest1,Bimap1-Canvas,Source1);
Form1-Canvas-CopyRect(Dest2,Bitmap1-Canvas,Source2);
for(j=0;j
}
}
5、在Items3的OnClieck事件中添加如下代码:
void__fastcall TForm1::Item3Click(TObject *Sender)
{ //图像从中间往上下分出//
Form1-Refresh( );
HeightHAlf=Bittmap1-Height/2+Bitmap1-Height%2;
for(i=0;i
{
Dest1=Rect(0,HeightHalf-i,Bitmap1-Width,HeightHalf);
Source1=Rect(0,0,BmpHandle-Width,i);
Dest2=Rect(0,HeightHaf,Bitmap1-Width,HeightHalf+i);
Source2=Rect(0,Bitmap1-Height-i,Bitmap1-Width,Bitmap1-height);
Form1-Canvas-CopyRect(Dest1,BmpHandle-Canvas,Source1);
Form1-Canvas-CopyRect(Dest2,BmpHandle-Canvas,Source2);
for(j=0;j
}
}
6、在Items4的OnClieck事件中添加如下代码:
void__fastcall TForm1::Item4Click(TObject *Sender)
{ //图像从上下往中间合进//
Form1-Refresh( );
HeightHalf=Bitmap1-Height/2+Bitmap1-Height%2;
for(i=0;i
{
Dest1=Rect(0,0,Bitmap1-Width,i);
Source1=Rect(0,HeightHalf-i,Bitmap1-Width,HeightHalf);
Dest2=Rect(0,Bitmap1-Height-i,
Bitmap1-Width,Bitmap1-Height);
Source2=Rect(0,HeightHalf,Bitmap1-Width,HeightHalf+i);
Form1-Canvas-CopyRect(Dest1,Bitmap1-Canvas,Source1);
Form1-Canvas-CopyRect(Dest2,Bitmap1-Canvas,Source2);
for(j=0;j
}
} (未完)
