How to get in MyComposer which item is selected from combobox ? I get null :(
<window id="autowin" apply="ui.MyComposer">
<combobox id="combo" selectedIndex="@{autowin$MyComposer.selected}"/>
</window>
public class AutoComposer extends GenericForwardComposer {
Object selected;
public void onChanging$combo(Event evt) {
System.out.println(selected); // null
}
}
If you set a model to the combobox, you can set the selection to model,
please refer to the component reference.
Thanks caclark
I tried this way before, but control was not coming in onCreate method, reason could be I declared this method without 'ForwardEvent' paramater. Will try this too.
Meanwhile, there is another way around :
In .zul file
<combobox id="billCountry"
onCreate="self.setSelectedIndex(editCompanyInfoWin$composer.getCurrentBillCountryIndex())">
.....
.....
</combobox>
Many thanks,
AJaikda
Hook the onCreate event of that component in your composer and do whatever you need to do...
public void onCreate$myComponentId(ForwardEvent event)
{
((Listbox)event.getOrigin()).setSelectedIndex(....)
}
Thank You very much as1225 :)
<combobox onCreate='self.setSelectedIndex(0);'>
My combo another:
<combobox id="autoType"> <comboitem label="osobowy" value="0"/> <comboitem label="ciężarowy" value="1"/> </combobox>
<combobox id="autoType" selectedIndex="0">
combo.setSelectedIndex(0);
As said by as1225, you can set the combobox as readonly.
So, users can only choose from the available options.
Hi,marioosh
you can try
<zk>
<combobox id="cb" >
<comboitem label="Simple and Rich"/>
<comboitem label="Cool!"/>
<comboitem label="Ajax and RIA"/>
</combobox>
<button label="readonly" onClick='cb.setReadonly(true);'/>
<button label="disable" onClick='cb.setDisabled(true);'/>
<button label="edit" onClick='cb.setReadonly(false);cb.setDisabled(false);'/>
</zk>
I have another question: How to block user for input something isn't in combobox ? :)
Do I have to do it myself or is there any method in api which does that ?
