I welcome!
Confronted with the problem. For example, take the
form
as shown below -
How do I put the button in this position? How do I put the button in this position? I would be very grateful for the information!
Cheers,

I have GroupCargoRecord class implements Serializable :

…also - attachField method in class, extends Form class:
...
@Override
protected void attachField(Object propertyId, Field field) {
if(propertyId.equals("companyName")) {
gridLayout.addComponent(field, 0, 1);
} else if (propertyId.equals("groupCargoName")) {
gridLayout.addComponent(field, 1, 2);
} else if (propertyId.equals("currentYearPower")) {
gridLayout.addComponent(field, 1, 3);
} else if (propertyId.equals("nextYearPower")) {
gridLayout.addComponent(field, 1, 4);
} else if (propertyId.equals("year2015Power")) {
gridLayout.addComponent(field, 1, 5);
} else if (propertyId.equals("year2020Power")) {
gridLayout.addComponent(field, 1, 6);
} else if (propertyId.equals("year2030Power")) {
gridLayout.addComponent(field, 1, 7);
}
}

I need to button near companyName field and another button near groupCargoName (the dialog’s will be invoked).
Does anyone know?
The following method does not give effect -
...
Field f;
...
HorizontalLayout hl = (HorizontalLayout)f;
TextField tf = new TextField();
Button b = new Button();
tf.setCaption("Предприятие");
tf.setRequired(true);
tf.setRequiredError("Поле \"Предприятие\" является обязательным для заполнения");
tf.setNullRepresentation("");
tf.setNullSettingAllowed(true);
tf.addValidator(new IntegerValidator("Мощность представляет собой целое"));
tf.setWidth(COMMON_FIELD_WIDTH);
hl.addComponent(tf);
hl.addComponent(b);
...
return f;
...
Hi,
I would try two ideas in this case. First, uglier one - is to tweak the content layout of the form. I mean you create a GridLayout, specify the number of rows/columns and add a Button so it is in a proper place (make sure that the FieldFactory will not try to add any fields in that cell). The other approach that I would rely on is a
СustomField add-on
. With it’s API you can wrap the button and a textfield into one field and attach it directly in the FieldFactory.

I welcome you, Alexander V Pchelintsev!
Many thanks for the info!
…Whew! The second method seems more interesting to me too, I’ll try to start.
You can also have a look at the
FormBinder add-on
and the pre-created fields pattern.
With that you can create your layout and let the form only connect the fields with your properties.

I welcome you, Claudio Crociati !
Hmm… Great idea!
Many thanks for the link, I will definitely try this add-on too!
Cheers,
Thx
