gtk_object_sink in glade_palette_init
Hello, This question could've gone to the glade list. But the explanation may help GTK programmers in general (I think), so I rather ask it here. In glade_palette_init, there's this piece of code : /* Add items tray (via a scrolled window) */ priv->tray = gtk_vbox_new (FALSE, 0); g_object_ref (G_OBJECT (priv->tray)); gtk_object_sink (GTK_OBJECT (priv->tray)); What's the goal of this gtk_object_sink ? I thought that after glade_palette_init returns, the local references are gone ? Is there a subtlety I don't get ? Kind regards, PhB P.S. Looking for the meaning of the gtk_object_sink call, at http://developer.gnome.org/doc/API/2.0/gtk/GtkObject.html#gtk-object-sink I see it's deprecated. g_object_ref_sink should be called instead (according to the gtk help) ? ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
RE: Suppressing command window
Thanks for your suggestions Jim, getenv(), putenv() are returning success as such. But when the application is being loaded immediately it will through gtk error, and closes the application. The same command, prepending (./GTK/bin;) to the current path works fine and the application launches successfully. I've never tried statically linking the application with GTK libraries and have to try it out. It's true that Xilinx ISE tools use QT, our team is developing supporting applications for FPGAs. As each QT license costs a higher price, we had to choose other tools for Windows GUI development. And for everybodys surprise GTK+ came out to be a wonderful tool, though available for free of cost.

Re: g_signal_connect_swapped
Richard, I'm also, as you are, a rather inexperienced GTK programmer, but I hope to still help you by the following, without immediately digging into all kinds of technical details : whereever the _swapped variant is used, that is done to call a callback from within a widget, to a procedure that's applicable on another widget (or even, in most cases another widget class). So e.g., a button press that should be calling some callback procedure on the window it is in, will use the _swapped variant (passing the window pointer as user_data argument). Doing so will make GTK's internal mechanics to "convert/abuse" that user_data argument's value, by putting it into the callback's call as it's *first* argument), so that the window's callback doesn't even realize it used to be the original widget's call's user_data argument). Hope this helps you more than it eventually further confuses you, Kind regards, PhB Richard Riley wrote: >"Matt Hoosier" <[EMAIL PROTECTED]> writes: > > > >>On 11/25/06, Richard <[EMAIL PROTECTED]> wrote: >> >> >>>Could someone explain the reason for this function >>> >>>"g_signal_connect_swapped" >>> >>>I have read the manual here: >>> >>>http://www.gtk.org/tutorial/x159.html >>> >>>where it says: >>> >>>, >>>| g_signal_connect_swapped() is the same as g_signal_connect() except that >>>| the instance on which the signal is emitted and data will be swapped >>>| when calling the handler.

Fullscreen window
I'd like to open my application with the window "expanded", so that it covers all the visible part of the desktop except the kde/gnome/windows taskbar(s). There is a portable way to do this? gtk_window_fullscreen does something similar but "removes" both the titlebar and the taskbar, at least on win32, on linux it doesn't do nothing but this is maybe dued to the fact I'm using a remote display for the application.

There are a number of ways to deal with this. The easiest will be to have your batch file call `start /B yourprogram.exe` after setting up the environment. There will be a console window opened when you launch the batch file and then immediately closed. Another relatively easy way is to use an Application Path and then you can simply run your executable. http://www.codeguru.com/Cpp/W-P/dll/article.php/c99 Another (probably more elegant) way of doing this is to have a launcher application that sets up your environment and does any other prep, then implicitly loads your application (using LoadLibraryEx) (this is what gaim and GIMP do).

RE: Suppressing command window
May be I was not clear in explaining my problem. I have used the -mwindows, which essentially suppresses all the debugging info(may be my printfs). But my requirement is different I've packaged the application along with the required GTK dlls in a zip file. Created a batch file, which, appends the current gtk\bin path to local path and then launch the application. And the console window, which was opened by the batch file will be visible till closed explicitly. My requirement here is either I shall be in a position to set the path through program, hence avoid the .bat requirement or automatically close the console was the application is launched. I tried using getenv() and putenv(), but it is not working as expected. What's the best way to distribute GTK+ application without batch file.

Link the executable with the flag -mwindows (if using the GNU linker) or /subsystem:windows (if using the Microsoft linker). If you use the Microsoft linker this also means, I think, your app should have a WinMain() instead of main().
