|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><span class="f_Heading1" style="font-size: 9pt; font-weight: normal;">父子连接只能用于选择按钮，或滑条的滑杠（实际上也是选择按钮）。</span></p>
|

<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><span class="f_Heading1" style="font-size: 9pt; font-weight: normal;">选择连接工具 </span><img alt="linkTool" width="27" height="28" style="margin:0;width:27px;height:28px;border:none" src="linktool.jpg"/><span class="f_ImageCaption" style="font-size: 9pt;"> </span><span class="f_Heading1" style="font-size: 9pt; font-weight: normal;">， 在选择按钮上点击，然后拖动将它连到另一个选择按钮。一个父子连接就被创建了。</span></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><span class="f_Heading1" style="font-size: 9pt; font-weight: normal;">如果要同时将多个选择按钮连到一个选择按钮上，只需要先选择这些源选择按钮，然后点击其中一个并拖动，到目标选择按钮上松开，即可以多连一。</span></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><span class="f_Heading1" style="font-size: 9pt; font-weight: normal;">父子连接持意义在于，在使用picker时，动画师可以双击父选择按钮，以便选择到父按钮及其所有子按钮的成员节点。</span></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><span class="f_Heading1" style="font-size: 9pt; font-weight: normal;">以下图为例：</span></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><img alt="parentLink.1" width="184" height="107" style="margin:0;width:184px;height:107px;border:none" src="parentlink.1.jpg"/></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><span class="f_Heading1" style="font-size: 9pt; font-weight: normal;">双击图中的Hand Control按钮，则选择到所有连接按钮的成员节点：</span></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><img alt="parentLink.2" width="184" height="107" style="margin:0;width:184px;height:107px;border:none" src="parentlink.2.jpg"/><span class="f_Heading1" style="font-size: 9pt; font-weight: normal;"> </span></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;">自MG-Picker工作室v1.7版开始，一个选择按钮可以有多个父选择按钮。</p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 24px;"><span class="f_Heading1" style="font-size: 9pt;">- 属性连接:</span></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><span class="f_Heading1" style="font-size: 9pt; font-weight: normal;">属性连接被属性按钮用来控制其它picker对象的可见性。</span></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><span class="f_Heading1" style="font-size: 9pt; font-weight: normal;">属性连接的源对象可以是任何类型的picker对象，像选择按钮，命令按钮，滑条，属性按钮，文 本及面板等，不过目标则只能是属性按钮。</span></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><span class="f_Heading1" style="font-size: 9pt; font-weight: normal;">它的效果是类似这样的的：假如你有一个属性按钮，它控制着其它所有picker对象：</span></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><img alt="attrLink.1" width="319" height="202" style="margin:0;width:319px;height:202px;border:none" src="attrlink.1.jpg"/></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><span class="f_Heading1" style="font-size: 9pt; font-weight: normal;">点击属性按钮的数值区，因为它是布尔类型，所以直接会从on切为off，结果其它所有picker对象就不可见了：</span></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><img alt="attrLink.2" width="319" height="202" style="margin:0;width:319px;height:202px;border:none" src="attrlink.2.jpg"/></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"> </p>

<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><img alt="lightbulb" width="16" height="16" style="margin:0;width:16px;height:16px;border:none" src="lightbulb.png"/><span style="font-size: 9pt;"> </span><span class="f_Heading1" style="font-size: 9pt; font-weight: normal;">在动画师模式下，属性连接完全不可见。而父子连接则以一个可配置的透明度可见，毕竟动画师需要父子连接判断双击的效果，而属性连接则没有太多显示的意义。</span></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><img alt="lightbulb" width="16" height="16" style="margin:0;width:16px;height:16px;border:none" src="lightbulb.png"/><span style="font-size: 9pt;"> </span><span class="f_Heading1" style="font-size: 9pt; font-weight: normal;">在动画师模式下，你可以点击属性按钮的任意一部分来切换它的属性。</span></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><img alt="lightbulb" width="16" height="16" style="margin:0;width:16px;height:16px;border:none" src="lightbulb.png"/><span style="font-size: 9pt;"> 不单单上面演示的布尔属性可以用来切换其它对象可见性，对于枚举类型，Maya属性类型的属性按钮，也可以用属性连接来控制其它对象可见性。</span></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><img alt="lightbulb" width="16" height="16" style="margin:0;width:16px;height:16px;border:none" src="lightbulb.png"/><span style="font-size: 9pt;"> 自MG-Picker工作室1.7版本及以后，任意picker对象都可以被多个属性按钮同时控制可见性，并且可以设置可见性的操作方式为"and"或"or"。"and"代表所有控制它的属性按钮数值符合目标值时，该对象才可见。"or"代表只要有一个控制它的属性按钮数值符合目标值时，该对象就可见。</span></p>
|
||
<p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 48px;"><img alt="lightbulb" width="16" height="16" style="margin:0;width:16px;height:16px;border:none" src="lightbulb.png"/><span style="font-size: 9pt;"> MG-Picker工作室2版本新添加<a href="relationshipview.htm" class="topiclink">关系视图</a>，可以帮助你了解这些可见性控制关系。</span></p>
