左键按下灵敏度

问题描述

我有一个OnRButtonDown函数..如果该点与数组中我的节点(DOUBLE中的X，Y)相符，它将显示一个对话框...

 如果(((post.x> = nodeX [j]- 5  || post.x< = nodeX [j] +5)&&(post.y> = nodeY [j]- 5  || post.y< = nodeY [j] +5))

该代码无效，我单击的所有区域均为TRUE ...
我想要当我在节点附近按下左键时也会显示对话框...

 如果(post.x == nodeX [j]&& post.y == nodeY [j]) 



上面的代码让我厌倦了精确的指针..

有没有简单的解决方案?或MFC为此提供特定的代码?

谢谢

I have a OnRButtonDown function..and it will show a dialog box if the point fit with my nodes (X,Y in DOUBLE) in an Array...



if((post.x>=nodeX[j]-5 || post.x<=nodeX[j]+5) && (post.y>=nodeY[j]-5 || post.y<=nodeY[j]+5))


that code doesn''t works, all area i click is TRUE for it...
I want when i press left button nearby the node it''ll show the dialog as well...

if(post.x==nodeX[j] && post.y==nodeY[j])


Code above makes me tired to precise the pointer..
Is there any simple solution? or MFC provide a specific code for it?
Thank You
