A test case should be as simple as possible. In the process of creating t=
hat
simple test case you will probably discover the error. Please reopen this=
 bug if
you create a test case.

For instance, some other header might be #define-ing something that break=
s the
gtkmm headers.

This really looks like discussion for the mailing list. Here, you just ge=

talk to me, instead of lots more informed people.

I guess that makes sense. If you're locale is UTF-8 then you shouldn't be=
 using
std::strings with API that gives/takes Glib::ustrings.

           Summary: ScrolledWindow::get_hscrollbar_visible() and
                    get_vscrollbar_visible() return wrong state
           Product: gtkmm
           Version: 2.6.x
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: general
        AssignedTo: gtkmm-forge lists sourceforge net
        ReportedBy: zoombat runbox com
                CC: all-bugs bugzilla gnome org


Distribution/Version: Gentoo ~x86 on a 2005.1 base

I think in the implementation of ScrolledWindow get_hscrollbar_visible()
and get_vscrollbar_visible() the methods return the wrong value (ie:
they return eachother's value rather than their own...) see the attached
screenshot for output:

std::cout << "HScrollbar: " << ImageScroller.get_hscrollbar_visible() <<
std::endl;

std::cout << "VScrollbar: " << ImageScroller.get_vscrollbar_visible() <<
std::endl;

In the screenshot it is clearly the HScrollbar visible but the output is
in reverse, or am I missing something?

------- Additional Comments From Bartek Kostrzewa  2005-09-27 12:05 -----=

I've checked scrolledwindow.ccg and scrolledwindow.hg in the source distr=
ibution
but I don't understand the _MEMBER_GET bit:

  _MEMBER_GET(vscrollbar_visible,hscrollbar_visible,bool,guint)
  _MEMBER_GET(hscrollbar_visible,vscrollbar_visible,bool,guint)

Is my assumption correct that this works as follows:

arg1 =3D get_* method name
arg2 =3D get_* object property
arg3 =3D return type
arg4 =3D implementation of return type (e.g. bool =3D guint)

if so then I think I've found the problem.. I'm going to try to reverse t=
he
second arguments, recompile and see what happens.

Ok, I now modified the correct files or maybe I don't understand the buil=
d
system or whatever... anyway, I went into the source distribution
gtk/gtkmm/scrolledwindow.cc ... I know it says do not modify but since th=
e other
tweak didn't do it...

and here indeed, get_hscrollbar_visible() returns gobj->vscrollbar_visibl=
e()
which seems fishy... and changing it made it behave as it should

Maybe there was some error in gtk and this was implemented like this as a=
 hotfix
and then forgotten?

 gtkmm | TreeView | Ver: 2.4.x

           Summary: Gtk::TreeViewColumn::set_widget() problems
           Product: gtkmm
           Version: 2.4.x
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: TreeView
        AssignedTo: gtkmm-forge lists sourceforge net
        ReportedBy: nightslayer gmx de
                CC: all-bugs bugzilla gnome org


Please describe the problem:
The Problem is about widgets that can be clicked/toggled/activated inside=
 a
Gtk::TreeViewColumn header.

- The header widgets (set with set_widget()) are only useable if they are=
 set
after the treeview is shown.
- If the columns are reorderable and after a column has been reordered, t=
he
widgets are unuseable again.
- There is a warning right after starting the attached program. Don't kno=
w what
it is: (main:2791): Gtk-CRITICAL **: gtk_cell_layout_add_attribute: asser=
tion
`column >=3D 0' failed

GTKmm: Debian package name: libgtkmm-2.4-1c2, Version: 1:2.6.2-1.1
(Sorry, but I have no clue what the actual version is)
Compiler: g++-4.0 (GCC) 4.0.1 (Debian 4.0.1-2)

Steps to reproduce:
1. See my attached code
2. Read the instructions/information in the comments

Actual results:
The descriped problem occures.

Expected results:
The widgets should ALWAYS be useable (clickable, etc), even if they are s=
et
BEFORE show_all() and also after a column has been reordered.

Does this happen every time?
Yes.

Other information:
Some Code. Compile with: g++ -o main main.cc `pkg-config --cflags --libs =
gtkmm-2.4`

#include <iostream>
#include <gtkmm.h>

class ColRecord : public Gtk::TreeModelColumnRecord
{
  public:
    ColRecord (void)
    {
      this->add(col1);
      this->add(col2);
    }

    Gtk::TreeModelColumn<Glib::ustring> col1;
    Gtk::TreeModelColumn<Glib::ustring> col2;
};

class TestWin : public Gtk::Window
{
  private:
    Gtk::CheckButton cb1;
    Gtk::CheckButton cb2;
    Gtk::TreeView tv;
    Gtk::TreeViewColumn tvc1;
    Gtk::TreeViewColumn tvc2;
    ColRecord cr;
    Glib::RefPtr<Gtk::ListStore> model;

  public:
    TestWin (void) : cb1("CheckBut 1"), cb2("CheckBut 2"),
        tvc1("Col1", cr.col1), tvc2("Col2", cr.col2),
        model(Gtk::ListStore::create(cr))
    {
      /* After reordering of columns, header widget is not useable. */
      tvc1.set_reorderable(true);
      tvc2.set_reorderable(true);
      tv.append_column(tvc1);
      tv.append_column(tvc2);
      tv.set_model(model);
      tv.set_headers_visible(true);
      cb1.show_all();
      cb2.show_all();

      add(tv);
      set_default_size(320, 200);

      /* Widget is NOT useable if it's set here. */
      //tvc1.set_widget(cb1);
      //tvc2.set_widget(cb2);
      show_all();

      /* Widget is useable if it's set here. */
      tvc1.set_widget(cb1);
      tvc2.set_widget(cb2);
    }
};

the
conclusion of this bug. I don't know how he digged up this bug, but if he=

------- Additional Comments From Simon Fuhrmann  2005-09-27 21:35 -------
There is another thing: If a column is reorderable, a single-pixel mouse =
move is
enougth to start reordering. This is a bit annoying if the columns are al=
so
clickable and clicking columns is often used (to sort the data or so).

In my opinion it would be better to start reordering after a few more
mouse-move-pixels.
