I've started building a small search engine for an index I created using Lucene. I use the GWT to create the GUI I like but I'm stuck in a problem. I am trying to add some results inside a FlowPanel which is inside the center of a DockLayoutPanel so I can have scrolling the page as I like. My problem is (as I found out ) that in order for scrolling to work ( and not have the browser window cut my results ) is to make every DockLayoutPanel child to not have position:absolute. My problem is that I cannot remove it ( or I don't know how ). When I disable it from chrome inspector scrolling works but when I re-enable it it cuts the flowPanel. Here is the java code :
public static void loadCellTrees(HashMap<Integer,LinkedHashMap<String,String>> searchResults, List<RootCategories> list)
{
VerticalPanel westTrees = new VerticalPanel();
TreeViewModel treeModel = new CellTreeWidget(list);
CellTree tree = new CellTree(treeModel, null);
HTMLBuilder builder = new HTMLBuilder(searchResults);
tree.setStyleName("tree");
tree.setAnimationEnabled(true);
dock.clear();
westTrees.clear();
westTrees.getElement().setAttribute("align", "center");
westTrees.add(tree);
FlowPanel resultsPanel = new FlowPanel();
resultsPanel.setStyleName("resultsPanel");
for(int i=0; i<searchResults.size(); i++)
{
HTML box = builder.toHTML(i);
box.setStyleName("resultBox");
resultsPanel.add(box);
}
dock.addWest(westTrees, 20);
dock.addNorth(RootPanel.get("wrap"),20);
dock.add(resultsPanel);
}
at the beginning of my code I add the dock (DockLayoutPanel ) to my RootLayoutPanel.
as I show at the first image... with position set to absolute I can have the scrollbar and the results are cut, but if I disable position: absolute as shown in the second pic
the scrollbar is enabled and I can have full access to all of my results.
The scrollbar is set like this :
RootLayoutPanel.get().getWidgetContainerElement(dock).getStyle().setOverflowY(Overflow.AUTO);
What I am trying to do is remove position for every dockLayoutPanel's child or set it to something else that doesn't creates me a problem.
I found a solution. On CSS styling simply I had to write
.cw-DockPanel > div {
position : initial !important;
}
If anyone has to suggest a better way than to use !important
i would be glad to hear it.
