Hi,
My Tree component is not showing up inside the Vertical split pane any
suggestions on what I may be doing wrong.
My component are laid out in this manner
I have a top level component
DockPanel
inside dock panel i have a Horizontal split pane
in my horizontal split pane the left component is Vertical split pane
and in top of vertical split pane I have a tree component
Now the issue is that Tree component is not showing up, if i keep it
anywhere else it works fine..
The code is also attached for review
public void onModuleLoad() {
DockPanel mainPanel = new DockPanel();
mainPanel.setBorderWidth(1);
mainPanel.setSize("100%", "100%");
mainPanel.setVerticalAlignment(HasAlignment.ALIGN_MIDDLE);
mainPanel.setHorizontalAlignment(HasAlignment.ALIGN_CENTER);
Widget header = new Label("Header");
mainPanel.add(header, DockPanel.NORTH);
mainPanel.setCellHeight(header, "30px");
Widget footer = new Label("Footer");
mainPanel.add(footer, DockPanel.SOUTH);
mainPanel.setCellHeight(footer, "25px");
// Create a tree with a few items in it.
TreeItem root = new TreeItem("root");
root.addItem("item0");
root.addItem("item1");
root.addItem("item2");
Tree t = new Tree();
t.addItem(root);
VerticalSplitPanel vSplit = new VerticalSplitPanel();
// If i don't set this value the panel will not show up properly
vSplit.setSize("100%", "100%");
//This IS THE PROBLEM COMPONENT
vSplit.setTopWidget(t);
vSplit.setBottomWidget(new HTML("Bottom"));
HorizontalSplitPanel hSplit = new HorizontalSplitPanel();
hSplit.setSplitPosition("50%");
hSplit.setLeftWidget(vSplit);
hSplit.setRightWidget(new HTML("right"));
mainPanel.add(hSplit, DockPanel.CENTER);
RootPanel.get().add(mainPanel);
}
