Do you have a /bin/cygatk-1.0.dll? If not, you only have the link library installed. I found this when building--you'll need to libtoolize with a recent libtool and rebuild all the autotools stuff. You might also need to add -no-undefined to the library _LDFLAGS or else the DLL won't get built. You'll see warnings when building the library if this is the case. -- Roger Leigh Printing on GNU/Linux? http://gimp-print.sourceforge.net/ GPG Public Key: 0x25BFB848.

gtk_widget_set_uposition() in Gtk-2.0?
I notice from the documentation that gtk_widget_set_uposition() is deprecated in Gtk-2.0, but there is no mention of how the same functionality should be implemented... Can anyone tell me? As a related point, even when I define GTK_DISABLE_DEPRECATED, I get no errors or warnings when trying to use deprecated functions. Have I misinterpreted the function of this flag? -- David J.

pixmap directory on windows
I finally got a few projects to compile. Now I guess I will go back and figure out how to do it with out using duct tape. Anyway, make install didn't seem to put my pix map files where they need to go so I put them there manually but it still gives me the error. I am wondering how the program finds the directories since /usr/local/share/calculator/pixmaps is only a valid dir inside cygwin where is my application really looking for the pixmap files? -- Chris W Bring Back the HP 15C http://hp15c.org Not getting the gifts you want?

I'm not sure you can get much faster than that with plain gtk :-( have you tried running: gtk+-2.4.x/tests/testrgb I get around 100 mega pixels per second draw speed for the fastest case (2.5 Ghz xeon, nvidia graphics card), it should be able to do 900 x 600 at video rates pretty easily. For more speed, I think you need to only update part of the display, or to use another drawing technique. mplayer has a mode where it decodes the video to an OpenGL texture, then uses an OGL window to draw that on the screen. Of course if you do this, your user will not be able to work over the network and will have to have OGL hardware installed and woirking.

I don't think you can expect a higher frame rate from a client-server infrastructure such as X windows. You will have to use an X extension to transfer the data more directly to the graphics card.

Get the coordinates from GtkDrawingArea and check the color code from the another image. Convert the color code to key. If you make the keyboard image with image manipulation software (like GIMP), it should be easy to select the color codes and paint over the keys. Select the colors numerically.

Is that >what you need? The demo looks great. I wrote a software with GTK 1.*, but now I changed to GTK 2.0. I did not change any code and I'm not sure should I change. I draw to 24-bit RGB rowstrided image which I created with malloc. I update the drawing area with gdk_draw_rgb_image(). The full update takes 80+ msec -- i.e., max frame rate is as low as 12 frames per second. Drawing to RGB image takes time as well, and so the frame rate drops too low. Image size is 900x600. When little objects moves in the image, the update is not a problem. How to get the full update faster? Are RGB images wrong choise for that? Is it wise to draw lines to RGB image by drawing to drawable and copying the content to pixbuf? I would not want re-write drawing routines?

Compile of gtk243 on cygwin fails at configure
Hi,
Odd situation here. Running cygwin 1.5x. Pango compiles and installs
successfully. atk compiles and installs successfully. glib compiles
and installs successfully. I used --prefix=/usr for all of them. gtk+
fails on the configure pass however with an error:
configure:29908: error:
*** Cannot link to Accessibility Toolkit. Accessibility Toolkit is required
*** to build GTK+
You know, of course, that atk is installed and there were no errors when
'make install' was run. The atk.pc file is in /usr/lib/pkgconfig and in
/lib/pkgconfig and it contains:
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
Name: Atk
Description: Accessibility Toolkit
Version: 1.6.0
Requires: gobject-2.0 gmodule-2.0
Libs: -L${libdir} -latk-1.0
Cflags: -I${includedir}/atk-1.0
And /usr/lib shows:
libatk-1.0.1
litatk-1.0.la
/usr/include/atk-1.0/atk exists and has the requisite .h files in it.
Any ideas? Seems odd that glib, pango, and atk all compile and install
without error but that gtk+, which finds glib and pango just fine, then
fails to find atk.
Regards,
Guy S.

How to create a scrolled text window with GTK 2.x?
In GTK 1.x I could say this: GtkWidget* textWindow = gtk_text_new(0, 0); GtkWidget* scrollBar = gtk_vscrollbar_new(GTK_TEXT(textWindow)->vadj); GtkWidget* hBox = gtk_hbox_new(FALSE, 0); gtk_box_pack_start(GTK_BOX(hBox), textWindow, TRUE, TRUE, 0); gtk_box_pack_start(GTK_BOX(hBox), scrollBar, FALSE, TRUE, 0); This created a nice scrolled text window which always scrolled to the end when new text appeared at the end of the text window. This is exactly the behaviour I want in an application I'm currently developing. However, I'm using GTK 2.x, and the above code is deprecated, and I'm unable to get the same behaviour with the new version of the library. I have been reading the API reference all over, but I don't get it. I have tried a similar code with the new GtkTextView widget, like this: GtkWidget* textWindow = gtk_text_view_new(); GtkWidget* textWindowScrollBar = gtk_vscrollbar_new(GTK_TEXT_VIEW(textWindow)->vadjustment); GtkWidget* hBox = gtk_hbox_new(FALSE, 0); gtk_box_pack_start(GTK_BOX(hBox), textWindow, TRUE, TRUE, 0); gtk_box_pack_start(GTK_BOX(hBox), textWindowScrollBar, FALSE, TRUE, 0); However, this doesn't work. The scrollbar is completely non-functional (and taking textWindow->vadjustment is probably non-standard as well). I have also tried this: GtkWidget* textWindow = gtk_text_view_new(); GtkWidget* scrolledTextWindow = gtk_scrolled_window_new(NULL, NULL); gtk_scrolled_window_set_policy(GTK_SCROLLED_WINDOW(scrolledTextWindow), GTK_POLICY_NEVER, GTK_POLICY_AUTOMATIC); gtk_scrolled_window_add_with_viewport (GTK_SCROLLED_WINDOW(scrolledTextWindow), textWindow); However, this doesn't work like I want: It does not automatically scroll to the end when new text appears at the end of the text window. How can I get the same type of scrolling text window as in GTK 1.x? And by the way, another question: For example the GtkPaned widget is specified to throw eg. a signal called "accept-position". However, if I create eg. a GtkVPaned and connect this signal to a function, like this: g_signal_connect(G_OBJECT(mainPanedWindow), "accept-position", G_CALLBACK(mainPanedWindowResize), NULL); nothing happens. The mainPanedWindowResize() function is never called. GTK is accepting this signal connection (because if I put an invalid signal name in the string, GTK prints an error message at runtime, but with "accept-position" it doesn't). The same holds for all the other signals GtkPaned is documented to throw (eg. "move-handle" etc). Even if I connect the signal with a function, the function is never called. To do what I wanted I had to connect the "size-allocate" signal thrown by GtkWidget, and that worked (even though the function is called more often than I would really want). But why doesn't connecting "accept-position" work? - Juha Nieminen ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
