Re: [ve-dev] Help with generating complex constraint objects

[Gerald Rosenberg <gerald@xxxxxxxxxx>]

Thanks.

(My target platform is Eclipse 3.2 and VE 1.2.  Development platform
is Callisto 3.2RC3.)

Next question is how to provide arguments to constructors as
generated.  I am able to automatically generate this code on a
layoutswitch:

private
JPanel getJPanel() {

if (jPanel == null) {

FormLayout formLayout = new FormLayout();

formLayout.setRowGroups(new int[][] {});

formLayout.setColumnGroups(new int[][] {});

jPanel = new JPanel();

jPanel.setLayout(formLayout);

jPanel.add(getJButton1(), new CellConstraints());

jPanel.add(getJButton2(), new CellConstraints());

}

return jPanel;

}

However, ...
The FormLayout signature as generated needs to be "new FormLayout(String, String)" 
The CellConstratins signature as generated needs to be "new CellConstraints(int, int, int, int)"

I am currently following the pattern of GridLayoutSwitcher to specify the form layout manager and create the "setRowGroups/setColumnGroups" initializers.  Not obvious how to also specify constructor arguments.

BoxLayout appears to be able to specify constructor arguments, but I have not succeeded in tracing through the source to see how it is done.

A pointer to the right place in the code to look and/or an explanation of the right methods to use would be appreciated.

It only understands the getName() against a component and field references and literals like String and numbers and new class creation calls.
