Delphi : keydown与keypress的区别,组合键

Shift 是一个集合变量。
type TShiftState = set of (ssShift, ssAlt, ssCtrl, ssLeft, ssRight, ssMiddle, ssDouble);
也就是说TShiftstate类型有ssShift, ssAlt, ssCtrl, ssLeft(鼠标左键), ssRight(鼠标右键), ssMiddle(鼠标中键), ssDouble (鼠标双击)

Value Meaning
ssShift               The Shift key is held down.
ssAlt                  The Alt key is held down.
ssCtrl                The Ctrl key is held down.
ssLeft                The left mouse button is held down.
ssRight             The right mouse button is held down.
ssMiddle            The middle mouse button is held down.
ssDouble          The mouse was double-clicked.

用来判断组合键中是否用shift、Ctrl、鼠标左键、右键、中键、双击事件。

 

Delphi中一些常用的组合键值

CTRL+A:#1 CTRL+B:#2 CTRL+C:#3 CTRL+D:#4 CTRL+E:#5 CTRL+F:#6 CTRL+G:#7
CTRL+H:#8 CTRL+I:#9 CTRL+J:#10 CTRL+K:#11 CTRL+L:#12 CR:#13 CTRL+N:#14
CTRL+O:#15 CTRL+P:#16 CTRL+Q:#17 CTRL+R:#18 CTRL+S:#19 CTRL+T:#20
CTRL+U:#21 CTRL+V:#22 CTRL+W:#23 CTRL+X:#24 CTRL+Y:#25 CTRL+Z:#26 ESC:#27
CTRL+:#28 CTRL+]:#29 SHIFT+CTRL+-:#30 DEL:#127
 

一般用在keydown、keyup、keypress事件中。
OnKeyDown和OnKeyUp事件中的Key是Word型的,表示用户按的是键盘上的哪个键,OnKeyPress中的Key是Char型,表示用户输入什么字符。一个产生8位(char)常规健值,一个产生16位(word)功能健健值。


1.KeyPress主要用来捕获数字(注意:包括Shift+数字的符号)、字母(注意:包括大小写)、小键盘等除了F1-12、SHIFT、Alt、Ctrl、Insert、Home、PgUp、Delete、End、PgDn、ScrollLock、Pause、NumLock、{菜单键}、{开始键}和方向键外的ANSI字符,KeyDown和KeyUp 通常可以捕获键盘除了PrScrn所有按键(这里不讨论特殊键盘的特殊键)

2.KeyPress 只能捕获单个字符

KeyDown 和KeyUp 可以捕获组合键。

3.KeyPress 可以捕获单个字符的大小写

4.KeyDown和KeyUp 对于单个字符捕获的KeyValue 都是一个值,也就是不能判断单个字符的大小写。

5.KeyPress 不区分小键盘和主键盘的数字字符。

KeyDown 和KeyUp 区分小键盘和主键盘的数字字符。

6.其中PrScrn 按键KeyPress、KeyDown和KeyUp 都不能捕获。


keydown是键盘按下任何键
keypress是键盘按下任何数字键和任何字母键

 

keydown 与keypress的声明格式差别很大

onkeydown事件
type TKeyEvent    procedure   (Sender:   TObject;   var   Key:   Word;   Shift:   TShiftState)   of   object;
property   OnKeyDown:   TKeyEvent;
该事件在有任何键按下的时候,就发生。看!它响应的是Word类型,还能识别Shift键状态
onkeypress事件
type   TKeyPressEvent    procedure   (Sender:   TObject;   var   Key:   Char)   of   object;
property   OnKeyPress:   TKeyPressEvent;
该事件响应的是字符类型Char,只能识别ASCII码,不能识别组合键和控制键和功能键。按下功能键、控制键不产生该事件,但产生OnkeyDown事件。

 

TWinControl与键盘相关的3个事件如下:
OnKeyDown:键按下
OnKeyPress:有Ascii字符产生
OnKeyUp:键放开

其中OnKeyDown、OnKeyUp对任何按键都有响应,传入参数为
var   Key:   Word 键的扫描值
    Shift:   TShiftState 表示控制键状态,包括键盘上的Ctrl、Shift、Alt和鼠标的左、中、右键及双击。
 
OnKeyPress事件只对Ascii有响应,传入参数为
var   Key:   Char Ascii字符
//例如F1-F10只有onKeydown有反应

另外TWincontrol.   KeyPreview:Boolean属性确定控件是否在子控件之前处理按键。

 

比如说enter键,
onkeypress事件

if  key=#13   then    //当你按下enter键时触发该事件
do  something

 
onkeydown事件
if  key=13  then     //当你按下enter键时触发该事件
do  something

 

 

其中所有的KeyDown事件里面应该用如下判断:
if Key = VK_RETURN then
...
所有的KeyPress事件里面应该用如下判断:
if Key = #13 then
...

postmessage(self.handle,wm_keydown,vk_tab,0);
keybd_event(VK_TAB,2,0,0);
perform(WM_NEXTDLGCTL,0,0);
SelectNext(ActiveControl, True, True);
...

但是显然用回车代码TAB显然不适合于BUTTON,你在它上面按回车的时候它会执行OnClick,所以不会TAB,你可以用别的键代替回车。

键值

 

在keydown事件里面
showmessage(inttostr(key));
在keypress事件里面
showmessage(key);
就知道了。

Form1.KeyPreview := True;

procedure TForm1.FormKeyDown(Sender: TObject; var Key: Word;
Shift: TShiftState);
begin
Showmessage(IntToStr(Key));
end;

procedure TForm1.FormKeyPress(Sender: TObject; var Key: Char);
begin
Showmessage(IntToStr(Ord(Key)));
end;

:),其实不用记,你不是用delphi吗,在ide里面输入vk_f1总会吧,然后按住ctrl键
单击刚才你输入的vk_f1,就会出来啦!
至于key:char的值,就是key:word的ascII码,你可以看chr(vk_f1),chr(vk_enter),都可以哈!

模拟鼠标

鼠标移动(移动量dx,dy)
mouse_event(MOUSEEVENTF_MOVE,dx,dy,0, 0 );
鼠标在(x,y)处按下或释放
setcursorpos(x,y);
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0 );
mouse_event(MOUSEEVENTF_RIGHTDOWN, 0, 0, 0, 0 );
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0 );
mouse_event(MOUSEEVENTF_RIGHTUP, 0, 0, 0, 0 );
鼠标双击由两次按下与释放来模拟

键盘模拟

一般虚拟键值(VK_)由KeyDown或keyup事件得到
特殊键值
Tab--9
Shift--16
Ctrl--17
Alt--18
CapsLock--20
Esc--27
Win--91,92
NumLock--144
ScrollLock--145

按下键
keybd_event(key, MapVirtualKey(key, 0 ), KEYEVENTF_KEYUP , 0 );
释放键
keybd_event(key, MapVirtualKey(key, 0 ), 0 , 0 );
以上做法对大多数键有效,少数键要用到不同的值

      Shift:   TShiftState); 
begin 
      if   key=VK_DELETE   then 
        key:=0; 
end; 

Delphi6.0,2000下通过Top
于在keydown中屏蔽掉除数字外的所有键
还应该允许Ctr+C/X/V,所以总结起来应该是: 

     procedure   TForm1.Edit1KeyPress(Sender:   TObject;   var   Key:   Char); 
begin 
     if   not   (Key   in   ['0'..'9',   #3,   #22,   #24,   #8,   #13,   #45])   then   Key   :=   #0; 
end;        

procedure   TForm1.Edit1KeyPress(Sender:   TObject;   var   Key:   Char); 
begin 
      if   (key>#57)   and   (key<#48)   then 
          key:=#0; 
end;         

我想你最好将你的例程写出来。 

        如果是像CKEN阁下说的那样,你要将按键事件屏蔽的话,实际上应该是直接赋值: 
        Key:=0;  

        (注意不是Key:=#0,因为这里的Key是Word类型,在keypress事件中,key的值是Char型,就要用“#”) 

        Good   luck

在KeyDown里面就可以实现 
if   key=vk_numpad0   then   (如果为小键盘的0键就干你想干的事情)
