让button在某些条件下隐藏

[jerry79]

当字段user_id等于当前登陆用户时，button不显示

<br />&lt;group attrs=&quot;{&#039;invisible&#039;: [(&#039;user_id&#039;, &#039;=&#039;, uid) ] }&quot;&gt;<br />&lt;button name=&quot;case_return&quot;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;  states=&quot;open&quot; string=&quot;返回&quot; <br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;  type=&quot;object&quot; icon=&quot;gtk-jump-to&quot; /&gt;<br />&lt;/group&gt;<br />

经过测试，下面的代码也是成立的：

<br />&lt;button name=&quot;change_deadline&quot;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; states=&quot;draft,open&quot;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; string=&quot;变更&quot; type=&quot;object&quot;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; icon=&quot;gtk-go-forward&quot;&nbsp; attrs=&quot;{&#039;invisible&#039;:[(&#039;user_id&#039;,&#039;!=&#039;,&#039;uid&#039;)]}&quot;/&gt;<br />

上面的代码表示，虽然button在draft和open状态下应该显示，但是根据attrs的附加条件，如果user_id不是当前登陆用户的话，这个button还是不显示。

<button name="change_deadline"
                            states="draft,open"
                            string="变更" type="object"
                            icon="gtk-go-forward"  attrs="{'invisible':[('user_id','!=',uid)]}"/>

记录：
6.1.1下会提示uid没有定义，官方buglist中此bug已经解决，但是截至今天（2012.6.28）下载的最新latest版本还是有次问题，只能手动修改，修改方法：
