disabled LinkRidget not rendered as expected [message #1073306]

Hello Group Members,

we upgraded Riena 3.0.0 to version 5.0.0 recently and encountered the following issue that wasn't there before:

When using a Link and LinkRidget and disabling it, there is no underlined text visible anymore but just a gray box without text. Could this be a bug?

cheers,
Christian

code snippet:

// UI
final Link link = new Link(parent, SWT.None);
bindControl(link, RID_LINK);
// controller
final ILinkRidget linkRidget = getRidget(RID_LINK);
linkRidget.setToolTipText("tooltip");
linkRidget.setText("text");
// disabling the LinkRidget let it appear as a gray box without text
linkRidget.setEnabled(false);

I tried this and for me underlined text is only shown if the link is set. What you did is you just set a text but no link.

What you have to do is do this:

linkRidget.setText("Go to Google","http://www.google.de");

Then the text is underlined, no matter whether enabled or disabled. I didnt try 3.0 to see if that has changed, but I tried that with the current HEAD version.

hope that helps
christian

sorry my fault. Actually you are right there is only a gray box.

Can you please add a bugzilla bug and we look into this Smile

I forgot to properly disable it...

BTW what was your expectation for a disabled Link ?

For disabled text fields we also remove the content (as you probably know). So for a link that is disabled, it means that you cannot click it anymore. Maybe remove the underline or totally remove it ?

Not sure.

Definitly it shouldn't be a gray box Smile

Hello Christian,

thank you for your quick reply!

Our expectation is that it behaves like it did in Riena 3.0.0, i.e.
text is shown (underlined), foreground color is light grey (probably represented by LnfKeyConstants.DISABLED_BACKGROUND) and clicking the Link doesn't trigger anything.

Btw that worked with Riena 3.0.0 and Eclipse_3.7.2. or E_3.8.2.
We are currently working with Eclipse_3.8.2.

Thanks,
Christian

There is a not so nice workaround: One could disable a parent Composite of the Link.
But with that workaround the foreground color of the Link remains same as enabled (dark blue).
