It's common convention that title bar close buttons of windows do a cancel-close. Especially if inside the window there are both "Cancel" and "OK" buttons as well. Hint: only using the "OK" button should confirm input or changes. Closing the window by any other means (i.e. "Cancel"-button, title bar close button, hitting the [Esc] key, killing or crashing the application) never does. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Some might have something like /proc/self/exe. Otherwise look at argv[0], and if it doesn't contain a directory already (possibly relative) look for the executable in $PATH, etc. Note that this method is trivial to spoof, so it shouldn't be used for anything that might have security consequences. On Windows, do GetModuleFileName() on the result of GetModuleHandle(NULL). If you want to be really correct, use the wide character version (and then convert pathname from UTF-16 to UTF-8 before passing to g_open() etc.) --tml ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

The HIG would love to say that alert and dialog titlebars shouldn't have a Close button unless the dialog is instant apply. The only reason it doesn't say that is because it's not technically possible to hide the Close button in metacity, AFAIK.

GtkSpinbutton up/down buttons remain depressed
Hi all, I am trying to write a gtk2-based gui for an app that visualizes antenna properties for different frequencies. The user changes freq by clicking the up/down buttons of a GtkSpinbutton that holds the current value of the frequency. I use the value_changed signal to read the new freq and then re-calculate and re-draw the new data in a drawingarea widget. Apparently GTK issues the value_changed signal before updating the spinbutton widget so that program flow goes to the functions that calculate freq data, which results in the up/down buttons remaining depressed, with the spinbutton value continually stepping itself up to it limit. I would greately appreciate any hints on this probelm, since its the last remaining bug in the GUI ;-) My thanks in advance! -- Regards NeoklisHam Radio Call: 5B4AZ QTH Loc: KM64MR ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Bayer Pattern images in Pixbuf or Pixmaps

extracting a portion of a GdkPixmap
I have a GdkPixmap. I need to programmatically extract a new GdkPixmap from this image based on x- and y-coordinates, plus width and height. The x, y, width, and height parameters will vary too much at runtime to store all the copies needed. Conceptually this seems simple. But from among the enormous number of different image formats and image-manipulation functions in GTK/GDK, I can't find a way to do it, after a *lot* of searching. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

I think you just make a new small pixmap of the size you need, then copy the pixels you want from your big pixmap into the small pixmap. The copy will (usually) be done in hardware, so it's very fast. You could consider using a pixbuf instead and doing the manipluation on the client side, but perhaps that doesn't suit your application. If it does, there's a very convenient pixbuf constructor: http://developer.gnome.org/doc/API/2.0/gdk-pixbuf/gdk-pixbuf-creating.html#gdk-pixbuf-new-subpixbuf John ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

You mean a simple demosaicing (debayering) technique? Well, a trivial one like "nearest neighbour" for the missing colour channels of each pixel is probably "simple", but it isn't good qualitywise. High-quality demosaicing algorithms are not simple. See for instance http://www.cs.pdx.edu/~cklin/demosaic/ .
