<p class="p_Normal" style="text-indent: 0; line-height: 1.80; padding-left: 13px; margin-left: 0;"><span class="f_Heading1" style="font-size:10pt; font-family: Arial,'Lucida Sans Unicode','Lucida Grande','Lucida Sans';display:inline-block;width:13px;margin-left:-13px">&#9642;</span><span class="f_ImageCaption" style="font-size: 10pt;">目前有2种picker连接</span><span class="f_Heading1" style="font-size: 10pt;">:</span></p><p class="p_Normal" style="line-height: 1.80; margin: 0 0 0 24px;"><span class="f_Heading1" style="font-size: 10pt;">- </span><span class="f_Heading1" style="font-size: 9pt;">父子连接:</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;">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;">&nbsp;</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&quot;and&quot;&quot;or&quot;&quot;and&quot;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。&quot;or&quot;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>
