Hello everybody,
I checked out the latest CVS today because Ivan finished his work on the
background gradients. Many thanks for that, Ivan!
Unfortionately the label I set as textClient of a section (it will soon
become a ToolBar) does not show up anymore. To add the label I use the
following code:
final Section searchSection = formsToolkit.createSection(body,
Section.TITLE_BAR | Section.TWISTIE);
Label label = formsToolkit.createLabel(searchSection, "");
label.setImage(image);
label.setToolTipText("Execute search");
searchSection.setTextClient(label);
Could this be a side-effect of Ivans patch? I have not changed my code
recently...
Thanks for your opinions and thoughts on that!
Regards,
Björn

Hi Björn,
yes... It seems that enabling background gradient in Section introduced
this problem. Please file a bugzilla about it to track the progress.

Hi Björn,
it is fixed in CVS HEAD. Thanks for pointing this out.

Hi Ivan,
thaks for resolving this so quick.
I have another question: are the rounded corners of Sections active by
default (like in RCP), or do I have to make a setting somewhere? I see
the background gradients, but the corners still seem to be rather sharp.

Hi Björn,
the rounded corners of Sections are not supported yet. If you need them
:-)... file an enhancement request.

Thanks for the explanation.

according to Benny and Ralf the rounded corners are supposed to work
already. Is it that the rounded corners only don't work on _Sections_,
but they do on other widgets? So where would they be working then (right
now there come no RCP widgets in my mind that have them...)?

Hi Björn,
the Sections already has rounded corners - just use the latest forms
plugin from CVS HEAD :-).

They work nicely for me! One thing I have noticed though is that the
separator on the form heading is not implemented yet. Should I raise a bug
for this?
Also, the border around the section gradient is not there either.
Cheers,
Paul

Hi Ivan,
yes I can confirm that, and also the rounded corners. Good work!
Concerning the Form gradient, ist this code supposed to work?
form.setHeadColor(IFormColors.H_GRADIENT_START, darkgrey);
form.setHeadColor(IFormColors.H_GRADIENT_END, lightgrey);
I tried to set the colors like this but (at least in my app) this does
nothing, there is still the white-to-light-blue gradient. Can the form
gradient colors be set in some other way?
Thanks for your hints!

Björn

Bjorn,
is this working in RCP? If you want to change the gradient colors, use
FormHeading#setTextBackground(Color[], int[], boolean):
.....
Color[] gradientColors = new Color[] {
darkgrey,
lightgrey
};
int[] percents = new int[] { 0, 100 };
head.setTextBackground(gradientColors, percents, false);
.....
For section use Section#setTitleBarBackground();
This should work.
Best,
Ivan

Hi Ivan,
sorry I did not cross-check this with RCP. You're right, it does not
work in RCP either, even though it should as I understand from this
document:
http://www.eclipse.org/eclipse/platform-ua/proposals/forms/e nhancements-3.3/index.html
Now I tried your alternative solution. The FormHeading class seems to be
not part of the public API, but Form has the method too:
------------------
Form form = formsToolkit.createForm(parent);
[set a HeadClient on the form]
Color[] gradientColors = { darkgrey, lightgrey };
int[] percents = { 0, 100 };
form.setTextBackground(gradientColors, percents, false);
formsToolkit.decorateFormHeading(form);
------------------
This leads to an ArrayIndexOutOfBoundsException in RCP (I don't really
understand why, maybe you can have a quick look at the stacktrace below?).
In RAP this simply does nothing, the gradient is still the default blue.
Any other ideas about that?
Googling on this topic brought me no further. Is it confirmed that
setting the gradient color of Form heading works anyway (in RCP or RAP)?
At least the API is quite confusing at this point.
Thanks for your help.
Regards,
Björn

Hi Björn,
this is the correct one. In RCP the percents array lenght must be with 1
less than the gradientColors array:
Form form = formsToolkit.createForm(parent);
[set a HeadClient on the form]
Color[] gradientColors = { darkgrey, lightgrey };
int[] percents = { 100 };
form.setTextBackground(gradientColors, percents, false);
In RAP only the vertical gradient is supported, that is way the third
parameter is ignored.
And don't call formsToolkit.decorateFormHeading(form);. This override
your colors set in setTextBackground with the default one.
Please update to the latest forms plugin from CVS HEAD. Today I've
updated the FormHeading class.
Best,
Ivan
