[Billy.Deng]

想请教大家，如何在前面板中放置一个布尔控件，当鼠标移入的时候，控件的图标会放大。

谢谢大家！！！

Would like to ask you, how to place a Boolean front panel control, when the mouse is moved when the zoom control icon.

Thank you! ! !

Your question is not clear. There is no zoom control icon, and no inherent  zoom capability in LabVIEW. Are you referring to the Navigation Window? If so, that's just a static window. You cannot place controls on it.

so , thank you so much, I think of that maybe I just want to zoom this control.Tonight I test one method to work out it. I use one event to mouse move in and one to move out the last use use property node to change its' . so this question is clear....

Thank you so much.

No, it is not clear. What control do you want to zoom ("this control")? Is this a graph indicator? Change what "its"? What is the boolean supposed to indicate? Zoom status?

你好，

你看看下面这种效果是不是你需要的：注册一个鼠标进入的事件，当鼠标进入控件所在的区域就会触发该事件，然后再事件框中通过属性节点调整控件的大小就可以了，当然要注意在鼠标离开时把控件大小改回原来的值。

So what is your question?  Does the code you show work or not work?

oh...I guess I am  a inattention.Yesterday I test two kinds control, one is boolean , the other is numeria.boolean can use, zoom status, move in ,zoom out ,move out ,zoom in. however, I want to make it more human. So I test it in labview PDA , but it can not use. the numeria is no satisfaction.

thank you ,I think so ,you are right.  But I have some new thinking.

 following is new question:

 what is control strict define(it show in PDA), & what will use strict define?

There is no Boolean control that does that. Are you sure you're not talking about a graph's palette??

Do you have some sort of custom control?

This is defined in the LabVIEW Help. A typedef is a control that allows you to define a data type and have all instances of that control automatically update whenever you change the control (though there are a few limitations). A strict typedef extends that to include visual elements, such as size and color.

您的方案我试过了，是可行的。

   但是我又想到一个新的问题，我可不可以把这个放大的功能封装起来，用子Vi的格式，想什么时候调用就什么时候调用呢？

[Billy.Deng]

I guess I am not express clearly. I had not use custom control. I just use event struct to change the control size, it means i resize it.

thank you.
