Changing label position when the field is not empty [message #1861434]

Hi there everyone,

I'm looking for a way to change label position automatically when the field (string, integer, long) is not empty.

In certain forms, I have LABEL_POSITION_ON_FIELD as the configured label position but once the user starts typing in the field, I want the label position to be on top i.e LABEL_POSITION_TOP. And if the value in the field is deleted, I want the label on the field again i.e LABEL_POSITION_ON_FIELD.

It is something I used to do with JavaFX and I would like to reproduce it with Eclipse Scout if possible.

Has anyone done this already?

Thanks a million for your assistance.

Cheers,

JD

Hello JD

I just tried something, it seems that it can work.

In the field class you can add this:

			@Override
			protected String execValidateValue(String rawValue) {
				if (rawValue==null||"".equals(rawValue)) {
					this.setLabelPosition(LABEL_POSITION_ON_FIELD);
				}
				else {
					this.setLabelPosition(LABEL_POSITION_TOP);
				}
				return super.execValidateValue(rawValue);
			};

When the user exits the field, or clears it, the execValidateValue method is called.

Remark: it doesn't work when the user starts typing, only when he is done. But I am not sure that as a user I would like the field to jump down as soon as I type in it.

Regards
Michael
