Hi Ralf,
I need the color and font dialog functionality as I am developing a
project that uses BIRT in RAP. My application has quite a few graphical
reports, and we have implemented our own chart designer, that allows the
user to customize the appearance of a chart according to his needs. Thus
the user should be able to customize the color(s) and font(s) of the
chart title, each data series, X and Y axis labels etc.
We have already implemented a similar functionality in a RCP app and
currently we are in the middle of porting the same to RAP.
In my particular case (and i guess in most cases where users will want a
font dialog in RAP), the font names displayed should be the one
registered on the server side, as the report will ultimately be
generated on the server. Currently we have solved these problems by
creating our own color dialog and font dialog in which we use the
GraphicEnvironment's getAllFontNames() and display the same to the user
in a drop down. However for the color dialog, we are using a JFace
dialog and then adding color selection functionality to it. Any pointers
as to how we can use the actual ColorDialog class?
Regards,
Anup Gokhale

That's an interesting case, thanks for your feedback.
But that means that the colors and fonts which are selected in the dialogs
are not used in the UI but in the backend of your application. This is fine
for colors but I think for fonts it's a problem. See below.

I do not agree to this point. Many applications use the selected fonts in
the frontend (such as the Eclipse IDE).
In a stand-alone RCP application, it makes no difference, whether selected
fonts are used in the frontend or in the backend as long as both live on
the same machine. But in RAP the frontend is always on the client (whose
available fonts we do not know) and the backend is always on the server
(which doesn't even have to have an X server and any fonts installed).
There is no problem with colors, as there are virtually all the same
everywhere (24bit RGB color space). Thus I think we can provide the
ColorDialog but for fonts a custom dialog is more appropriate as long as we
don't have some clever solution.

If you like to implement the ColorDialog by yourself, you could create a
custom widget that encapsulates the qooxdoo ColorSelector [1]. We are open
for contributions :) Please refer to the RAP help [2] for how to write
custom widgets.
Best,
Ralf
