Connector Labels (Polyline Connection) [message #1059231]

Hi,

In one diagram I have a figure element that is the representation of a Polyline and for it I attached a label with a text. The Label is the one that you can show/hide in the diagram view by Show/Hide Connector Labels. When the text that goes to the Label becomes long, I need to make it multiple line or have it multiple line from the beginning. I tried to change the type from a Label to a Custom Figure and set the CustomAttribute textWrap to true , but not possible to see this happening the moment the Label is displayed in the Diagram Editor.
Any idea is welcome.

Hi Dan,

your generated EditPart has most likely an underlying "WrappingLabel" as its figure, which has the

setTextWrap(...)

implemented by default.
Make sure, when you perform the actual editing on the label to use CTRL+Enter to insert a linebreak, as only enter will commit the currently edited text.

Regards
Thomas

Hi Thomas,
I know that setTextWrap could do the trick. Just to make the picture more detailed:
- I have this text for the label taken from two other properties, based on the user selection of a flag. So I am extracting the text to be displayed like this:

public String getUsedGuard()
{
if(this.isRuleFromGrammar == true){if(basicGetGuardRuleName() != null)
return basicGetGuardRuleName().getRuleName();
else
return "";
}
else{
return this.getGuard();
}
}

So finally I will have a string that will populate the label. So the label is not edited directly in the view, but managed through other properties. This is why I am searching another way of forcing the label to have itself more lines and to manage the text that comes within.

Hi Thomas,

Can you share the sample code for adding the label to the polyline figure?

Should we add the label as a child to a polyline figure?
