I have a large application and deep in the nested panels there's a
problem where a panel size doesn't seem to obey the requested size.
It works as expected up to the size of bodyPanel. The bodyPanel panel
ends up with the same height as appPanel. Shouldn't it be 50% of
appPanel's weight instead?
Here's my sample program. I tried to eliminate as much as possible
and still reproduce the problem. I using gwt-linux-1.4.62
----------------------------------------------------------------------------
package com.mudd.client;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.core.client.*;
import com.google.gwt.user.client.ui.*;
import com.google.gwt.user.client.*;
public class panelSizeDemo implements EntryPoint {
public void onModuleLoad() {
try {
main();
}
catch (Exception e) {
log(e.getMessage());
Window.alert("General Error:\n" + e);
}
}
static RootPanel root = RootPanel.get();
static HorizontalPanel basePanel = new HorizontalPanel();
static VerticalPanel logPanel = new VerticalPanel();
static VerticalPanel appPanel = new VerticalPanel();
static VerticalPanel bodyPanel = new VerticalPanel();
public void main() {
root.add(basePanel);
basePanel.setSize("100%", "100%");
basePanel.add(logPanel);
basePanel.setCellWidth(logPanel, "30%");
basePanel.setCellHeight(logPanel, "100%");
logPanel.setSize("100%", "100%");
basePanel.add(appPanel);
basePanel.setCellWidth(appPanel, "70%");
basePanel.setCellHeight(appPanel, "100%");
appPanel.setSize("100%", "100%");
appPanel.add(bodyPanel);
appPanel.setCellWidth(bodyPanel, "100%");
appPanel.setCellHeight(bodyPanel, "50%"); // Why doesn't this
have an effect?
bodyPanel.setSize("100%", "100%");
log("root "+root.getOffsetWidth() + " "+root.getOffsetHeight());
log("basePanel "+basePanel.getOffsetWidth() + "
"+basePanel.getOffsetHeight());
log("logPanel "+logPanel.getOffsetWidth() + "
"+logPanel.getOffsetHeight());
log("appPanel "+appPanel.getOffsetWidth() + "
"+appPanel.getOffsetHeight());
log("bodyPanel "+bodyPanel.getOffsetWidth() + "
"+bodyPanel.getOffsetHeight());
}
public static void log(String msg) {
logPanel.add(new Label(msg));
}
}
----------------------------------------------------------------------------------------------------------
Output in compile mode:
root 1103 656
basePanel 1103 656
logPanel 331 656
appPanel 772 656
bodyPanel 772 656 <-- why does this match appPanel's size?
Ultimately I only care about the results in compile mode but here's
output in shell mode for reference.
root 774 445
basePanel 774 445
logPanel 232 445
appPanel 542 445
bodyPanel 0 0
