[Emf Forms] Tooltips in Views [message #1723503]

Hello,

is there a way to change the tooltip within the Forms-views?

I mean the tooltip that appears over the Attribute-Name-Lables ...
Currently it shows : _UI_PropertyDescriptor_description from
plugin.properties (in generated edit-Plugin) resulting in

"The <attribute> of the <class>"

But I want to defined a custom tooltip for each eClass and for each of
its Attributes...

Best regards
Oliver

Hi Oliver

I was recently trying out an Extension point from ECP :
org.eclipse.emf.ecp.ui.view.tooltipModifier
This extension point is mention for changing the tooltip on the controls
rendered by ECP. Not sure if this can be used for Label Tooltips also.

I have documented my learning in an article. You may find a link to the
article below.

Hi Oliver,
the text you see is the default text that is generated by emf. You can find it in the generated plugin.properties of your edit bundle. There is this entry:
Quote:

_UI_PropertyDescriptor_description = The {0} of the {1}

Now you can of course customize this. Open the GenModel Editor, select the feature you want to change, and in the properties view add the description you want to the property "Property Description".
If you now generate the edit bundle again, you will find an extra entry at the bottom.
Something like this:
_UI_Task_name_description = The name of the task should not be longer then 72 characters

The TooltipModifier is used to modify prepared tooltips, eg if you have a very long description but want the tooltip to be 50 chars wide, you can provide a modifier that adds line breaks to the provided text so the resulting tooltip will not be to wide.
You can also replace magic keys using your own modifier.

Cheers,
Eugen

Update:

I got a hint to use the Extensionpoint
"org.eclipse.emf.ecp.ui.view.tooltipModifier"

This is not exactly what I was looking for, but perhaps a good
workaround. :-)

So I implemented a Class to modify the tooltip for the rendered
controls. This works as far as I can see...BUT:
....now I get lots of messageboxs for each "number" Attribute saying :

"Invalid Number"
"The Number you have entered is invalid. The value will be unset."

Unfortunately there is no stacktrace, no nothing....
I traced this back to NumberControlSWTRenderer, but then I lost
orientation while debugging in all those classes...

Is this a bug ? How to avoid this?!

regards
Oliver
