Have charts to work with a RootPanel based application

[yaniv54321]

hello,

i have a GWT app based on RootPanel and not RootLayoutPanel

but it seems that the only way i can use charts (gwt-charts-0.9.10.jar) is
by using RootLayoutPanel

i have tried to find a simple fix by searching the following possible fixes:

1. have an app based on both RootPanel and RootLayoutPanel.
2. have a way to contain RootLayoutPanel inside a RootPanel.
3. have the chart to work in RootPanel without using RootLayoutPanel.

so fur , none of the above works ,

does any one have an idea on how to progress with this

Did you try to put the chart inside a SimpleLayoutPanel ?

i tried something like this

public class TestFrame extends Composite {

PieChart pieChart ;

public TestFrame() {

VerticalPanel verticalPanel = getPnl();
initWidget( verticalPanel );

Button btn = new Button("graph");
btn.setSize("100%", "100px");
btn.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
setViewPieChart();
}});
verticalPanel.add(btn);

}

public static VerticalPanel getPnl(){
VerticalPanel verticalPanel = new VerticalPanel();
verticalPanel.setWidth("300px");
verticalPanel.setHorizontalAlignment(HasHorizontalAlignment.
ALIGN_LEFT);

return verticalPanel;
}

private void setViewPieChart() {

ChartLoader chartLoader = new ChartLoader(ChartPackage.CORECHART);
chartLoader.loadApi(new Runnable() {
@Override
public void run() {
SimpleLayoutPanel layoutPanel = new SimpleLayoutPanel();
PieChart pieChart = (PieChart)getPieChart();
layoutPanel.setWidget(getPieChart());
pieChart.draw(getDataTable());

RootPanel.get().clear();
RootPanel.get().add(new TestFrame2(layoutPanel));
}});

}

private Widget getPieChart() {
if (pieChart == null) {
pieChart = new PieChart();
}
return pieChart;
}
}


**********

public class TestFrame2 extends Composite {

public TestFrame2(SimpleLayoutPanel layoutPanel) {

VerticalPanel verticalPanel = getPnl();
initWidget( verticalPanel );

verticalPanel.add(layoutPanel);

}

public static VerticalPanel getPnl(){
VerticalPanel verticalPanel = new VerticalPanel();
verticalPanel.setWidth("300px");
verticalPanel.setHorizontalAlignment(HasHorizontalAlignment.
ALIGN_LEFT);

return verticalPanel;
}
}
