ECP/ EMF Forms , wordwrap in text widgets [message #1248666]

Hello,
does anyone know if it is possible to have wordwrap in the widgets displaying lots of text in EMF Forms. It seems to be that the standard widgets supplied for showing text attributes in the RCP and RAP version of ECP are always as wide as the longest line of my multi-line text. So if I have a sentence that is 400 characters long, then my text widget is 400 characters wide which makes it difficult to read.
I tried using some vertical and horizontal layouts, but this didn't solve my problem.
Maybe there is anther way to do it with layouts/spans, or maybe I can create a custom widget for this. I am particularly interested in this working with the RAP version of ECP.
Thanks,
Neil

Hi,

thank you for the report, we can reproduce this:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=428397
A work-Around would be to regsiter your own control:

However, it would be great to receive a contribution for this BR, too.

Best Regards

Thanks,
I will have a look into finding the problem,I suspect its to do with settings such as SWT.SINGLE and/or similar on the Text widgets
I have the source code from git for branch release_1.20
It is fairly clear how to compile it and run the code for the RCP version, I have few questions about working with the source code for RAP,

1.)For RAP should I compile against the ECP_RAP target? This is currently pointing to EMFStore 1.0 and not 1.1, and doesn't allow everything to compile, but maybe it allows enough o compile to run ECP on RAP?)
2.)Should I launch with the rap2 run configuration from git, is this kept up to date?
3.) Should the 1.2 branch always compile and run fro RAP, or is it sometimes less stable
4.) is there a way get the state of the code as it was released for RC1, RC2 etc.

Thanks,
Neil

Hi,

Before I can answer your questions: which branch have you checked out?
on master you always find the latest release (1.1.1) on develop you will
find the latest state. The sources of the RC for 1.2.0 can be found in
this branch: release_1.2.0

Best regards

Jonas

btw I think I have found a simple fix to the problem, I will test it a bit further.

In the Class org.eclipse.emf.ecp.edit.internal.swt.controls.StringControl

I replaced
gridData.heightHint = 200;
with
"gridData.heightHint = 200;
gridData.widthHint = 200;"

I replace this in the methods where gridData.heightHint = 200 exists (so both getTextWidgetStyle() and getTextWidgetLayoutData(), its probably not needed in the first one)

I don't know how to specify that my control should be multiline for my model elements attributes so I have forced it in the code for now.

I thought this fix would limit the width to be 200 always, but instead it does exactly what I want, it wordwraps the text to however wide the text area gets.
Will test further.

Regards,
NEeil

I havent tested this on RAP yet btw.
Multiline I found I can set in my .genmodel file.
It appears that the change is indeed only needed in getTextWidgetLayoutData()
It looks like this change would mean that the text area never gets less width than 200, which is ok for me, dont know about other users, something like 50 might be better.

Neil

By setting the property type to multi line (in the genmodel)

Neil, once you have found out exactly what you need, please consider to
file a bug report. Please let me know, if there are any open questions...

thanks, I have updated the bug report for the multiline wordrap issue.
I cannot test my change yet on RAP as I cant launch a working RAP app from the release 1.2 branch (for which I have raised Bug 428647 - Cannot launch RAP with supplied ecpRapDemo launch script)
