Grid's Columns and Hflex
This section introduce the usage of ZK auto sizing APIs, all of these can apply to following components :
Use Cases
Here we take grid with column as an example, showing some use case about how to use the right way to display the data.
Data Length : Short
<syntax lang='xml' high='12,13,14,15,16'> <zk>
<zscript><![CDATA[ String[] msgs2 = { "Application Developer's Perspective", "Server+client Fusion architecture", "Component Developer's Perspective", "Execution Flow of Loading a Page", "Execution Flow of Serving an Ajax Request", "When to Send an Ajax Request" }; ]]></zscript>
<listbox width="800px">
<listhead> <listheader label="Product" /> <listheader label="Description" /> <listheader label="Comment" /> </listhead> <listitem>
<listcell><label value="${msgs2[0]}"></label></listcell>
<listcell><label value="${msgs2[1]}"></label></listcell> <listcell><label value="${msgs2[2]}"></label></listcell> </listitem> <listitem> <listcell><label value="${msgs2[3]}"></label></listcell> <listcell><label value="${msgs2[4]}"></label></listcell> <listcell><label value="${msgs2[5]}"></label></listcell> </listitem>
</listbox> <zk> </syntax>
Proportional Width
In this case, the default data component will show the data correctly, width proportional width 1 : 1 : 1
Sure you can use the hflex we have mentioned in previous section.
<syntax lang='xml' start="13"> <listhead>
<listheader label="Product" hflex="1"/> <listheader label="Description" hflex="2"/> <listheader label="Comment" hflex="1" /> </listhead>
</syntax>
Minimum Flexibility
In the cases of hflex=min, if you your content fill the whole data component, you can use span=true
<syntax lang='xml' start="2" high='5,8'>
<zscript><![CDATA[ String[] msgs2 = { "Application Developer's Perspective", "Very Short Text", "Server+client Fusion architecture", "Execution Flow of Serving an Ajax Request", "Very Short Text", "When to Send an Ajax Request (Addition Text )" }; ]]></zscript>
</syntax>
- Origional
<syntax lang='xml' start="13"> <listhead>
<listheader label="Product" hflex="min"/> <listheader label="Description" hflex="min"/> <listheader label="Comment" hflex="min" /> </listhead>
</syntax>
- Set span=true
<syntax lang='xml' start="12" high='12'>
<listbox width="800px" span='true'>
<listhead>
<listheader label="Product" hflex="min"/> <listheader label="Description" hflex="min"/> <listheader label="Comment" hflex="min" /> </listhead>
</syntax>
Data Length : Long
Data Length : Dynamic
