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
}
}
you have the false event. . Look at the docs here
public void onSelect$combo(Event evt) {
System.out.println(selected); // null
Thanks :)
Finally I get this working! :)
I had big problem with "selected". I didn't know that i have to declare two bean methods for selected to get this working....
<combobox id="combo" autodrop="true" selectedItem="@{autowin$AutoComposer.selected}" >
public class MyComposer extends GenericForwardComposer {
Client selected;
Combobox combo;
public void onSelect$combo(Event event) {
System.out.println("onSelect "+selected);
}
public Client getSelected() {
return selected;
}
public void setSelected(Client selected) {
this.selected = selected;
}
}
I have another question: How to block user for input something isn't in combobox ? :)
Do I have to do it myself or is there any method in api which does that ?
Hi,marioosh
you can try
<zk>
<combobox id="cb" >
<comboitem label="Simple and Rich"/>
<comboitem label="Cool!"/>
<comboitem label="Ajax and RIA"/>
</combobox>
<button label="readonly" onClick='cb.setReadonly(true);'/>
<button label="disable" onClick='cb.setDisabled(true);'/>
<button label="edit" onClick='cb.setReadonly(false);cb.setDisabled(false);'/>
</zk>
As said by as1225, you can set the combobox as readonly.
So, users can only choose from the available options.
My combo another:
<combobox id="autoType"> <comboitem label="osobowy" value="0"/> <comboitem label="ciężarowy" value="1"/> </combobox>
<combobox id="autoType" selectedIndex="0">
combo.setSelectedIndex(0);
<combobox onCreate='self.setSelectedIndex(0);'>
Thank You very much as1225 :)
Hook the onCreate event of that component in your composer and do whatever you need to do...
public void onCreate$myComponentId(ForwardEvent event)
{
((Listbox)event.getOrigin()).setSelectedIndex(....)
}
