As far as I can work out, there isn't currently a way to control the
appearance of a EWL button label (i.e. the Ewl_Button.label_object) from
an edje theme, other than using the global /entry/* data items. I'm
guessing the same applies to all EWL text in general.
The main drawback to this, other than restricting themeability, is the
fact that the button's Edje 'programs' cannot affect the button label
(e.g. to gray the text when the button's disabled, or to animate it on a
click). I'd ideally like to be able to use Edje's rel1/2, font, size,
fit, align, color and programs to theme my EWL button labels...
I'd like to try and fix it, so perhaps Nathan or others could tell me
what they think of this initial thinking:
The problem as I see it is that an Edje part of type TEXT will not apply
its settings to EWL text. Rather, it will create an additional
Edje_Part which is not reflected in the EWL object hierarchy.
In other words, if you apply an Edje TEXT theme to a EWL text widget,
you end up with *two* Evas text objects superimposed.
Assuming that's right, then perhaps the right solution begins along
these lines....
OPTION A
Ewl_Text (actually Ewl_Entry) is currently creating an Evas Textblock
object. This is not consistent behaviour with other widgets (e.g.
Ewl_Button) which do not create a visible object, but rely on the Edje
theme to do this for them.
So, Ewl_Text/Entry should not explicitly create an Evas Textblock, but
rather get a handle to that generated by Edje. If no appropriate Edje
group is found, then nothing should be displayed.
I presume the problem with this approach is that Edje creates an Evas
Text object, whereas EWL uses an Evas *Textblock*, and that this is
necessary for text-editing capability. If so, then should EWL have
another simpler text object which uses Evas Text and allows themeing, or
should Edje support Textblocks?
OPTION B
Allow Ewl_Entry to create the Textblock as it currently does, but
somehow get Edje to theme that object rather than creating its own Text
object...
Thoughts?
