Dynamic remove of a component in a ContentPanel

[Kirua007]

Hi,

I would like to knwo how can I remove a component from a panel:

I try this :

ContentPanel cp = (ContentPanel) this.getWidget();
cp.removeAll();
cp.layout();

But component in the screen still be visible ....

With an dynamic add there is no problem , no problem with a dynamic sizing of the panel too

Thank you for your answer

You want to remove the ContentPanel or all children ofthis ContentPanel? With your code you remove all children of that contentpanel.

[Kirua007]

All children of the panel in order to have a "blank" panel ...

Than that code is correct. If it is not working, please post a fully working testcase that implements EntryPOnit

I found the origin of the problem

My panel doesn't contain classic component but my own component which extend composite (of GWT librairie)
My component :

public class ComplexField extends Composite {
    
    ElementType myElement;
    int size;
    String label;
    HorizontalPanel horizontalPanel;
    
    public ComplexField(ElementType element,int size,String htmlLabel)
    {
        this.myElement=element;
        this.size=size;
        this.label = htmlLabel;
        horizontalPanel = new HorizontalPanel();
        horizontalPanel.setSpacing(10);
                
    }

    public ElementType getMyElement() {
        return myElement;
    }
    
    public void removeAll()
    {
        HorizontalPanel  horizontalPanel = (HorizontalPanel)this.getWidget();
        horizontalPanel.removeAll();
        horizontalPanel.layout();
    }
}

With my own component, the removeAll of the panel doesn't work. Component stay on the screen
So I add the removeAll function on my component and I call it before calling removeAll of the Panel

ContentPanel panel = (ContentPanel)this;
        for(int i=0;i<panel.getItemCount();i++)
        {
            ComplexField cf = (ComplexField)panel.getWidget(i);
            cf.removeAll();
        }
        
        panel.removeAll();
panel.layout();

Like this, it's works but I am not sure of the solution ...

Is It normal ?

Thank you
