在C ++ Builder 6中拖放图像 [英] Drag and drop images in C++ Builder 6

问题描述

我在制作Puzzle程序，现在我如何使用导航键移动图片部分，但是如何使用鼠标？

我试过

  Image1-> Top = Mouse-> CursorPos.x; 
 Image1-> Left = Mouse-> CursorPos.y; 
  

有任何帮助吗？

/ p>

我把它放在Timer中，但Image开始在两个位置闪烁...

 code> int difference_x = Form1-> Image1-> Left  -  Mouse  - > CursorPos.x; 
 int difference_y = Form1-> Image1->顶部 - 鼠标 - > CursorPos.y; 
 
 int xxx = Mouse-> CursorPos.x  -  difference_x; 
 int yyy = Mouse-> CursorPos.y  -  26  -  difference_y; 
 // 26是游标高度
 
 Image1-> Top = yyy; 
 Image1-> Left = xxx; 
  

解决方案

我卖掉了我的问题。

我在OnMouseDown事件中做到了：

  difference_x = Form1-& > Left-Mouse-> CursorPos.x; 
 difference_y = Form1-> Image1-> Top-Mouse-> CursorPos.y; 
 Timer1-> Enabled = true; 
  

此计时器：

  int xxx = Mouse-> CursorPos.x + difference_x; 
 int yyy = Mouse-> CursorPos.y + difference_y; 
 
 Image1-> Top = yyy; 
 Image1-> Left = xxx; 
  

I'm making a Puzzle program and I now how to move the picture parts with navigation keys but how do I do that using mouse ?

I've tried using this but picture is acting like crazy

Image1->Top=Mouse->CursorPos.x;
Image1->Left=Mouse->CursorPos.y;

Any help?

Edit:

I put this in Timer but Image started blinking in two places at once...

    int difference_x=Form1->Image1->Left - Mouse->CursorPos.x;
    int difference_y=Form1->Image1->Top  - Mouse->CursorPos.y;

    int xxx=Mouse->CursorPos.x - difference_x ;
    int yyy=Mouse->CursorPos.y - 26 - difference_y;
                              // 26 is Cursor height

    Image1->Top=yyy;
    Image1->Left=xxx;

解决方案

I've sold my problem.

I did this in OnMouseDown event:

difference_x=Form1->Image1->Left-Mouse->CursorPos.x;
difference_y=Form1->Image1->Top-Mouse->CursorPos.y;
Timer1->Enabled=true;

and this on Timer:

int xxx=Mouse->CursorPos.x +difference_x ;
int yyy=Mouse->CursorPos.y +difference_y;

Image1->Top=yyy;
Image1->Left=xxx;
