I have been facing a particular problem. I want a layout with 2 horizontal regions (using border layout), such that I can hide any one of them any time I want. They both should also be collapsible. I tried to do this with combinations of regions like Center-South, North-Center but I am not able to hide or collapse the Center region. I even tried the combination North-South, but then it does not render my toolbar properly.
Can you do a north/south, while defining the center region in your layout? Then you could use a combination of YAHOO.ext.LayoutManager.getViewSize() and the collapsed, expanded, resized events on the north/south regions to set the size of those regions, keeping center at 0px.
You can have a look at the basic layout I want. Everything except the Page Header should be collapsible. I should also be able to hide them. I am using Border Layout.
Actually our application has some old modules, which need to be displayed as is. And some newer ones which I have converted in a Grid and a corresponding Preview Pane Beneath it. However, both the kind of modules can be accessed from a common tree on the left. Now, when a user clicks on a new module, he should see a grid and a preview pane. No probs till now. But when he clicks on an old module, there should be no grid, and the entire content of the page should be displayed in the right area (Grid + Preview area) as is.
So I thought I would make an Iframe in the Preview Pane and when an old module needs to be loaded, I will simply hide the Grid Area and then load the corresponding page in the Iframe. But I am not able to hide the Grid coz it is defined as "Center" area, and as Jack said, its a fill. So, it cant be collapsed or hidden. And I cannot make it "North" and make the Preview Pane "Center" coz the Preview Pane should be collapsible.
I figured out an easier solution... I loaded 2 content panels in the center region, one with the grid and one with an empty Iframe.... then when I need to load the old modules, I just hide the south region and also the gridpanel.... otherwise I hide the Iframe panel and show the other two
But I have a small problem now, I have a tab panel in the center region, and I am not able to make it go away.....
