Re: [ve-dev] Border Layout implementation not working

[Peter Walker <walkerp@xxxxxxxxxx>]

From what you have described and the
snapshots... it sounds like your border layout is working successfully
in the IDE (with regions showing correctly). But the problem might be in
the remote vm where the actual layout is applied and components are added
to the container. Are you sure you have your build path setup correctly
to include the plugin with your special layout manager?

One of the ways we debug is to enable
a debug option that adds a check box preference option ("Show Live
Window") to the VE preferences page. When this option is checked,
it shows the actual frame/panel you are working with in the Visual Editor.

To add this option to the preferences,
create a debug options file (options.txt) and start Eclipse with the options
file using the parameter:
   -DEBUG file:/c:/temp/options.txt

The options file should contain the
following statement:
   org.eclipse.ve.java.core/debug/livewindow=true

Once Eclipse starts, go the VE preferences
page and check the option "Show Live Window". Open VE on your
class and the live window should show up in the upper left part of the
your screen. As you make changes in VE you should see them in the live
window. VE screen scrapes the images from the live window back into the
IDE where you are working in the graph view. If the live window doesn't
show the jButton component when you switch to your layout, this indicates
the layout is not working in the remote vm and the first place to look
is the classpath.

Hope this helps...

Subject	[ve-dev] Border Layout implementation not working

Hi All, 
    We are trying to implement a swing layout in VE 1.1.  We
are trying to bring up the borderlayout in our project to learn the flow
for implementing a Layout in V.E. I have extracted the source for all the
layout support files such as Borderlayouteditpolicy, BorderLayoutSwitcher
etc and the BorderLayout from jfc source. The code is compiling and it
is able to pick up the layout support classes. But it is not executing
properly. I am attaching few snap shots to explain.

In the first snap shot I have used the regular BorderLayout. You can see the panel being selected.
In the second snap shot I have selected a button on the same panel.

I am not able to duplicate the same in my borderlayout implementation.

Next I change the layout to CMyBorderLayout that is a copy implementation of the actual border layout.
You can see in the third snap shot that the component on the panel has vanished.
In the fourth snap I have selected the button from the 'Java Bean View'

In the Fifth I tried to drag another object from the component plaette on to the container. You can see the borderlayout grid helpers visible.

The button is not visible on the container . But it is placed somewhere at the edge (0,0) . Can anybody please tell me ,Where should I start debugging and what could be the problem. There are no error messages in the log.

Thanks in Advance.
