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

[Rich Kulp <richkulp@xxxxxxxxxx>]

Hi,

Sorry, but the current code parsing
doesn't understand method calls to anything other than  getControl().getName()
for the constraint argument in the add call. It only understands the getName()
against a component and field references and literals like String and numbers
and new class creation calls.

So if you change to instead of your
format to (Note: This is in VE 1.2. I don't know if this works in VE 1.1,
we made many changes since then):

jPanel.add(getJButton1(),
new CellConstraint(1,1))

we would be able to parse and understand
this, assuming the FormLayout you created would take a "CellConstraint"
as a constraint.

You can open an enhancement request
against VE to allow method calls there instead.

Subject	[ve-dev] Help with generating complex constraint objects

Working on implementing 

protected IJavaObjectInstance
convertConstraint(Object constraint) {

in FormLayoutPolicyHelper.  Given that the "constraint"
parameter is of type CellConstraints, and is a singleton, how do I specify
the further qualification of the constraint 

1) to use a particular method, in this case ".xy(int col, int row)",
2) with assigned method parameters of my choice, and 
3) yield an IJavaObjectsInstance.  

None of the existing layouts provide a reasonably close example.  

An example of the desired form of the jPanel.add(Component c, Constraint
cc) statements to be generated by VE:

private
JPanel getJPanel() { 
if
(jPanel
== null)
{ 
String colSpec = "..."; 
String rowSpec = "...";

FormLayout formLayout
= new FormLayout(colSpec, rowSpec); 
CellConstraints cc =
new CellConstraints(); 
jPanel
= new
JPanel(); 
jPanel.setLayout(formLayout);

jPanel.add(getJButton1(),
cc.xy(1,1));
// add at col 1, row 1

jPanel.add(getJButton2(),
cc.xy(2,1));
// add at col 2, row 1 
}

return
jPanel;

}

Thanks,
Gerald
