Re: Cross-Platform GUI
I've looked into this extensively and one of these days will finish up my blog writeup on it. For now: There are plusses and minuses for each - make a list of the most important things you need and see how they compare. Fltk - pretty simple to use. Nice small, static compiles. Dialogs are easy to code but not the best looking. There is no layout manager, just a awkward resizable command. Awkward, static callbacks instead of signal, slots. No major backers or major projects using it. Most examples and documentation are C style. I never really understood Fluid as a dialog editor. wxWidgets - didn't explore too much after looking at code - I guess if you are coming from Visual C++ it might look more familar. I've read some comments against it, other comments that say it works great - I believe Audacity uses it. Seems to be a viable option. There's also Fox toolkit - seems to have excellent Ruby bindings. No Mac support. Seemed pretty ugly. Supported mostly by 1 person (though he is very responsive). No dialog editor. Gtkmm - gtk is being backed by most major Linux players (Red Hat, Novell, Sun ) And of course Gnome, XFCE, all the Gtk apps. Gtkmm is very c++ like. Uses the excellent libsigc for signal/slots. Has a very good layout manager. Confusing library dependencies but uses Pkg-Config to make compiling easy. Use XFC documentation, it's much better. (XFC is a great library too, but only for Linux). Gtk apps certainly being used on Windows. Mac ?? not too sure - maybe others can comment. Depending on your situation - you might want to look at Qt - it's a good, easy to use toolkit. Very cross-platform, excellent documentation. Good looking. Very C++ oriented. The moc signal stuff is non C++ but works well. Moc causes Qt to be slow to compile. Well supported. As someone who has to sign the checks, I think it is way too expensive for our use but it's your call. Don't forget java SWT - the advances of gcj may bring native compilation of Swing. And the next version is supposed to support native widgets. Bottom Line: We chose gtkmm based mostly on the industry support for gtk, the free license, the layout manager abilities, the availability of glade (though we're not using it yet), and libsigc. If XFC becomes cross-platform we will strongly consider it (both use mostly the same gtk wrapper commands). hope this helps.

Re: GTK on Linux and Windows
Great. That's what I supposed too... Now it all depends on what my teacher meant when he wanted the GUI to be portable... Any way, thanks again.

Re: Cross-Platform GUI
Overall, I think gtkmm would be a good choice. wxWidgets and FLTK are quite cumbersome, and they don't offer you the flexibility that is found in gtkmm and/or C++. there is one important consideration that nobody has mentioned so far. portability to Aqua rather than X11.app on OS X. GTK has seen two efforts to port it to Aqua, using different approaches. Both projects appear to be essentially dead. This means that you cannot use GTK (and by implication, gtkmm) to write native apps for OS X - your users are forced to use X11.app and your applications will have X-styled appearances, not Aqua-like ones. several people have offered to invest some amounts of money in my digital audio workstation software ardour to do a native OS X port, and i have told them find someone you can pay to port GDK to Aqua - this will benefit a large number of applications rather than just ardour. unfortunately, nobody has taken the suggestion up, and the projects remain silent and stationary AFAICT. by contrast, wxWidgets is native on Aqua. --p ___ gtkmm-list mailing list gtkmm-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtkmm-list

How to update display in another thread ?
Hi All,
I want to display a plane on the screen based on the position
information given by remote machine. So I create a thread waitting
for the position information. When this thread got the
information, it should update the display position in the
window. How can I reach this ?
I tried this:
thread_function()
{
...
wait_for_information(position);
window-set_plane_position(position);
window-on_expose_event();
...
}
But it got an error when running:
Xlib: unexpected async reply (sequence 0x708)!
Any suggestion will be apprecieate!

I search the mailing list and the reference documentation. And find
the solution. I'm sorry that I didn't do this earlier. The following
is my solution:
1) In the GUI thread
---window.h---
class MainWindow {
public:
...
void on_dispatcher_notify() {
on_expose_event(NULL); }
void update_display() { dispatcher.emit(); }
private:
Glib::Dispatcher dispatcher;
...
};
---window.cpp---
MainWindow::MainWindow()
{
...
dispatcher.connect(sigc::mem_fun(*this,
MainWindow::on_dispatcher_notify));
...
}
2) In the other thread
thread_function()
{
...
wait_for_information(position);
window-set_position(position);
window-update_display();
...
}

Preserving window geometry and position between invocations
Hello,
I'd like to preserve window position and size between invocations.
I can restore the size nicely using:
Gtk::Window::set_default_size(width, height)
but I cannot seem to restore the position that nicely. The only thing I
could get so far is this ugly hack:
void BuffyWindow::on_show()
{
Gtk::Window::on_show();
// Retrieve x and y from the configuration
move(x, y);
}
However, this shows the window where the WM says it, then moves it where
I want it. Besides not looking nice, I understand one should be more
cooperative with the WM.
What is the right way of doing this?
Ciao,
Enrico
