Drawing eletrocardiogram graphs

Hi there.
I was intending to develop some program that could analyse
eletrocardiograms graphs. Data could be saved into xml and be opened
and represented (drawn) for further analysis.

What I would like to know is if there is anything easier than Cairo to
be used to draw using gtkmm (C++ or just C).
Any info on that would be appreciated.

Thanks in advance.

Yeah, we need to mention the stable glibmm 2.10 and unstable glibmm
2.11/12 too, and in the sidebar too.

Just with the existing links, please. Thanks.

Is seems fine now.

Maybe you are confusing it with the link to a separate wiki that Alex
Buehl just posted.

Subject: How to delete a multiple selection from a ListStore?
I want to be able to delete / cut / copy and paste multiple-selections in a
TreeView.

What I do now obviously doesn't work correctly, presumably because the
iterators pointing to the rows change as soon as I change the model?
This is what I do now:
----------------code snippet:
std::vector<Gtk::TreeModel::Path> pathlist =
pView->get_selection()->get_selected_rows();
for (std::vector<Gtk::TreeModel::Path>::iterator i =
pathlist.begin(); i != pathlist.end(); ++i)
                pd_expModel->erase(pd_expModel->get_iter
(*i));
----------------

What would be the correct way to delete a multiple selection from the model?

cheers, Joost

Subject: Re: How to delete a multiple selection from a ListStore?
Ok, I've found something that atleast works, although I'm not sure if
it's the best way of doing it:


--------------
for (Gtk::TreeModel::iterator iter =
pd_expModel->children().begin();iter;)
                                if (treesel->is_selected(iter))
                                        iter = pd_expModel->erase(iter);
                                else
                                        ++iter;
-------------
I'd be interested to know if there's a better way of doing this.

cheers,

Joost

Subject: Re: How to delete a multiple selection from a ListStore?

 Convert your original list of selected rows into a list of
Gtk::TreeModel::RowReferences.  Using this list you can use the paths it
contains when you loop through the list calling the model's erase method.
The path each Gtk::TreeModel::RowReference contains remains valid so long as
the row to which it points exists regardless of the fact that you are
changing the model by deleting rows.

 Hope this helps.

I want to have different behaviors on right-drag and left-drag.  How
do I find what button is being used for the drag?

I've never quite understood the need for this class. A path is already
only a potential path. When you convert it to an iter then the iter will
be invalid if the path isn't valid at that time. (In the example code,
he's not checking the result of get_iter(), I see.)

And if we were just storing paths then the paths wouldn't indicate the
same rows if we have deleted the rows before the intended row.

Maybe RowReference always provides a valid (at the time, sometimes
different than originally) path.

You don't really use pkg-config directly; the configure scripts for
what you're installing use it.  You merely provide some external
direction for it.

Basic idea:  packages provided pkg-config files (for example, gtk
+-2.0.pc).  These files tell pkg-config how to tell the build system
for another package how to build and link against the first package.
Now, to find those files, pkg-config must know where they are.
They're installed to $PREFIX/pkgconfig by packages.  So, if glib is
installed in /opt/gtk2, and you want to link GTK against that glib,
you'd run GTK's configure script like so:

$
PKG_CONFIG_PATH="/opt/gtk2/lib/pkgconfig:$PKG_CONFIG_PATH"
./
configure <configure args as normal>

thereby setting the environment variable on the command line.
Optionally, you can set it in your .bashrc, .bash_profile, or
whatever the initialization script for your shell is.
