Hi,
I am trying to use the collapsible panel
I have downloaded the incubator jar (gwt-incubator-20100204-r1747.jar)
the styles are not reflecting and the hover bar is appearing although
on click of toggle button it is sliding but then I am not able to see
it any how or slide it back.
I am getting the following exception:
If I try to set the width of the collapsible it ,if is not then the
exception does not appear but nor does it work as i see it in the live
demo.
The underlying content width cannot be 0. Please ensure that
the .container css style has a fixed
widthjava.lang.IllegalStateException: The underlying content width
cannot be 0. Please ensure that the .container css style has a fixed
width

here is the sample code I have tried:
protected HorizontalPanel hPanel = new
HorizontalPanel();
HorizontalPanel panel = new HorizontalPanel();
CollapsiblePanel collapsiblePanel = new
CollapsiblePanel();
panel.add(collapsiblePanel);
DOM.setStyleAttribute(collapsiblePanel.getElement(), "border",
"solid 1px black");
ToggleButton toggler = new ToggleButton("Directory (click to
pin)",
"Directory (click to collapse)");
toggler.setStyleName("CollapsibleToggle");
VerticalPanel contents = new VerticalPanel();
contents.add(toggler);
contents.add(treeView);
FlowPanel navBar = new FlowPanel();
navBar.setSize("200px", "100%");
navBar.add(contents);
collapsiblePanel.add(navBar);
collapsiblePanel.setWidth("100px");
DOM.setStyleAttribute(navBar.getElement(), "border", "solid 1px
black");
String value = Location.getParameter("collapsed");
if (value != null) {
value = value.trim();
if (value.equals("true")) {
collapsiblePanel.setCollapsedState(true);
}
else if (value.equals("false")) {
// do nothing, default.
}
else {
Window.alert("collapsed should not be given " +
value + " use true
or false instead");
}
}
collapsiblePanel.hookupControlToggle(toggler);
panel.setWidth("100%");
hPanel.add(panel);
please let me know where I am wrong...
thanks,
Komal
