[Wt-interest] Where is the source for Wt's "internal stylesheet"?

[K. Frank]

Hello List!

I am new to Wt and working with Wt 3.3.3.

I am working with the example DialogExample.C, and looking
at line 28:

textdiv->setStyleClass("text");

As I understand it, this line uses a style sheet to set some
formatting rules for the WContainerWidget textdiv, and because
DialogExample doesn't load any style sheets, I assume it's using
what the Wt documentation refers to as the "internal stylesheet."

But browsing the source, I can't find any definitions for the rules
for the internal stylesheet. I see a number of css files here and
there in the source tree, but none of them contain anything that
looks like it would map to a set of rules for "text" or "buttons".

Another possibility is that there is no Wt-provided style sheet,
and that the setStyleClass() calls ultimately map to some
default browser styles. If that's the case where might I find
(typical) rules for the browser-provided style sheet?


Thanks.


K. Frank

Hello Freddy (and (Koen)!

Post by Koen Deforche
Hey,
Only Wt 3.3.4-rc1 or the git version of Wt builds fine with boost 1.57.

For what it's worth, I was able to build Wt 3.3.3 with boost 1.57
with some minor patches. (It did not build out of the box.) This
was on 64-bit windows 7 with a recent gcc 4.9.2 version of mingw-w64

I did not see this specific error. Again, as mentioned above, this was
on windows, not mac.

To get (on windows) wt 3.3.3 to build with boost 1.57 I had to patch
boost, adding a missing include file, per:

https://svn.boost.org/trac/boost/ticket/10100

and patch Wt to bring it up to date with boost's spirit parser-generator
header files, per:

http://redmine.webtoolkit.eu/issues/3561

With a little fiddling, Wt 3.3.3 with boost 1.57 was possible for
me. But again, I didn't see the error you saw, so my windows /
mingw-w64 comments might not be relevant to your situation.

(I had no compelling reason not to upgrade to Wt 3.3.4-rc1;
I just wanted to stick with an official "stable" version. Going
with Wt 3.3.4 might well be the more practical solution.)

Sorry, I don't know the answer to your question.

(My previous comment might not be relevant to your specific
situation. I just wanted to give the one data point about my
experience with Wt 3.3.3 / boost 1.57 / mingw-w64. I've never
built Wt on a mac, nor used Wt from git, nor used anything but
Wt 3.3.3.)

You'll find the definition in DialogExample.C line 66.

Hello Wim!

Thanks very much -- I should have noticed that myself.

I have a couple of quick follow-up questions:

Just so I understand, does the "internal stylesheet" start out
empty so that without the calls to styleSheet().addRule() it
would have no effect?

Also, just a syntax / formatting question about the ".":
(I'm new to Wt and css).

I see (in DialogExample.C)

textdiv->setStyleClass("text");
styleSheet().addRule(".text", "padding: 4px 8px");
styleSheet().addRule("body", "margin: 0px;");

Could someone explain the structure whereby ".text" matches
"text" (with and without the ".", respectively), and why we call
addRule with ".text" and "body (with and without the ".", respectively)

Thanks again for sorting this out for me.

Hi Frank,

Correct, you need to add styles to your document (internal stylesheets or
external stylesheets).

In relation to the selectors (.text, body, ...) I recommend you to google
and read about CSS selectors. Wt just passes these on to the browser.

Best regards,
Wim.
