[Dillo-dev] Problem using "Textblock" Class.

23 Mar 2010

      Hello Johannes,

To make things simple, I added a method in the file findtext.cc which is as
under:
The purpose of this method is to access "Textblock" from the file
findtext.cc.
-----------------------------------------------------------------------------------------------
/* RMP */
void FindtextState::getLink (void)
{
   MSG("\n RMP: getLink function");
   Textblock *textblock = new dw::Textblock (false);

   textblock->getNextLink ();
}
/* RMP */

-----------------------------------------------------------------------------------------------
I have included "textblock.hh" in the file 'findtext.cc'.

I still get an error like shown below:

============================================================
../dw/libDw-core.a(findtext.o): In function
`dw::core::FindtextState::getLink()':
/home/rmarathe/dillo-2.2/dw/findtext.cc:299: undefined reference to
`dw::Textblock::Textblock(bool)'
/home/rmarathe/dillo-2.2/dw/findtext.cc:301: undefined reference to
`dw::Textblock::getNextLink()'
collect2: ld returned 1 exit status
make[2]: *** [dw-imgbuf-mem-test] Error 1
make[2]: Leaving directory `/home/rmarathe/dillo-2.2/test'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/rmarathe/dillo-2.2'
make: *** [all] Error 2

============================================================
...
From the file findtext.cc it seems we are not able to get hold of the
constructor or any other methods in TextBlock class.
Please let me know the changes that are needed to make the above work.
I can do a code clean-up later once the above starts working.

regards,
Rajesh Marathe.

Hi,
I am trying to implement the support for using the tab or other keyboard
keys to set focus on web page links. As part of this, I started out with
adding a new Class and would like to use some sort of iterator in this
class. I would also like to use the 'Textblock' object to retrieve the
style->x_link for a word. However, when I try to initialize the
Textblock object in my new class, I get a linker error. The details are
as under:
The basic skeletal code for new class is:
========================================
findlinks.cc
namespace dw {
namespace core {
FindLinks::FindLinks ()
{
   widget = NULL;
   iterator = NULL;
}
FindLinks::~FindLinks ()
{
   if (iterator)
      delete iterator;
}
void FindLinks::getlink (void)
{
        MSG("\n Hi !! I came to findlinks");
        Textblock *textblock = new Textblock (false);
}
I have included "dw/textblock.hh" in the above file and also included
core.hh.
I guess it's because Textblock is in the dw namespace, not dw::core,
so removing "namespace core {" in the above example should fix it.
Alternatively you could use "new dw::Textblock (false);".
...
Compilation goes through but I end up with a linker error as under:
=====================================================================
../dw/libDw-core.a(findlinks.o): In function
`dw::core::FindLinks::getlink()':
/home/rmarathe/dillo-2.2/dw/findlinks.cc:25: undefined reference to
`dw::Textblock::Textblock(bool)'
collect2: ld returned 1 exit status
I believe that I still need to use "iterator" and the Textblock" classes
to implement this feature. Am I using the Textblock in a right way or am
I missing something in the above code ?
Please do let me know,
Hm, I can't really tell from the code above.
I would expect some code that uses the existing iterator mechanism
to walk through a page and find links and buttons, and so on.
Maybe you could use findtext.cc as an example.
Regards,
Johannes
PS: The keyboard navigation feature would be highly appreciated!
