When do you expect it to be called?

[mrhari]

when content panel is going to exapnd. after collapsing it

[sven]

Where, in which sceneria? Standalone or in a BorderLayout?

[mrhari]

in a bordeLayout

[sven]

A BorderLayout is not doing a collapse/expand on a ContentPanel. You need to listen to the Events.BeforeExpand event on the BorderLayout.

[mrhari]

ya i am expecting a before expand event .

[contentPannel.addListener(Events.BeforeExpand,
new Listener<ComponentEvent>() {
public void handleEvent(ComponentEvent ce) {
}
})][/CODE]

Events.BeforeCollapse event is working..

[sven]

ya i am expecting a before expand event .

[contentPannel.addListener(Events.BeforeExpand,
new Listener<ComponentEvent>() {
public void handleEvent(ComponentEvent ce) {
}
})][/CODE]

Events.BeforeCollapse event is working..

Please reread my response. A BorderLayout is not doing a real Collapse/Expand and therefor you cannot listen to the events on the ContentPanel.

[mrhari]

so i must add listener to border layout right?

[sven]

Yes. Also note than that a BorderLayout does not fire a ComponentEvent but a BorderLayoutEvent

[mrhari]

Thank you very much. I will do like you said.

I cannot follow you.

[mrhari]

i am adding content pannel and a border layout data in dialouge box. and set border layout data as collapsible.and what i need is the collapsible and expandable events.please look the code

[
ContentPannel pannel =new ContentPannel();
BorderLayoutData data = new BorderLayoutData(LayoutRegion.NORTH,
);
data.setCollapsible(true);
DialougeBox box=new DialougeBox();
box.add(pannel ,data)
][/CODE]

Isnt this what we just did already? The BorderLayout fires these events.

Events.Collapse, Events.Expand, Events.BeforeCOllapse and Events.BeforeExpand.

[mrhari]

so did this work pannel .getLayout().addListene(rEvents.BeforeExpand,
new Listener<ComponentEvent>() {
public void handleEvent(ComponentEvent ce) {
}});

[sven]

so did this work pannel .getLayout().addListene(rEvents.BeforeExpand,
new Listener<ComponentEvent>() {
public void handleEvent(ComponentEvent ce) {
}});

"pannel" does not have the BorderLayout. According to your last code "box" has it. Also please reread all my posts in this thread


Yes. Also note than that a BorderLayout does not fire a ComponentEvent but a BorderLayoutEvent

[mrhari]

so is it work pannel.getLayout().addListener(Events.BeforeExpand,
new Listener<ComponentEvent>() {
public void handleEvent(ComponentEvent ce) {
}});

[mrhari]

thank you very much.as you said the layout data is associated with the box.and i am looking it with the panel..now i got it.thank you for your patience.
