所以我得到了一些非常简单的标记,其中包含一个工具栏内的按钮。
现在的问题是,即使按钮“正确”写入 DOM,它也不会显示出来。
有关详细信息,请参阅此屏幕截图:
有人介意解释为什么设置固定的高度/宽度/位置不会将按钮带到前面并且包含的标记元素都具有width=0px;
或height=0px;
吗?
这是一个示例:
<body>
<ext:ResourceManager ID="RM" runat="server" />
<ext:Viewport Layout="BorderLayout" runat="server" ID="InnerView" OverflowY="Scroll">
<Content>
<ext:Button ID="adminswap" runat="server" Text="Admin-Ansicht umschalten" Hidden="false"
AllowDepress="true" MinHeight="16" ToFrontOnShow="true" Visible="true" Icon="ArrowSwitchBluegreen">
<%-- This Guy doesn't show up--%>
</ext:Button>
<ext:Panel runat="server" ID="order" Border="false" OverflowY="Scroll">
<LayoutConfig>
<ext:TableLayoutConfig Columns="3" />
</LayoutConfig>
<Items>
<ext:Panel runat="server" Layout="ColumnLayout" RowSpan="2" Border="false">

<p> And here is some Grid-panel, which is of no further interest</p>
