Anyone knows answer to this mystery? Of course that's because the height of the client window area is not divisible by the fonw height. Unlikely. Well, it can be bug in fonts or freetype/gtk/pango (whoever decides font height from the font file) but most probably it is just because the font is not rendered from the top so there is 1 or 2 lines missing on the bottom. I tried two 16px/12pt height fonts both having the same problem Fixedsys Excelsior http://www.fixedsysexcelsior.com/ Terminus http://fractal.csie.org/~eric/wiki/Terminus_font http://chlamydia.fs.ei.tum.de/~corecode/unsorted/Terminus.ttf BTW, later I tried this also in Gnome terminal in Ubuntu 8.04 and I see exactly the same problem when in fullscreen mode (F11, right click - turn off menu bar). Screen height 800 is divisible by 16 but I see same empty line on the bottom and same hairline white border around Midnight Commander's blue panel and see only 49 lines instead of 50. This also means it is not Maemo specific so it does not belong here. You may want to try DejaVu Sans Mono, the pre-packaged DejaVu fonts can be downloaded here: http://cs.ozerki.net/zap/maemo/dists/diablo/main/binary-armel/ttf-dejavu_2.25-1_all.deb In my opinion, DejaVu Sans Mono gives a much nicer appearance to the terminal. Tried it just to verify the bug and now I have another mystery :-) I am no expert on font sizes and units but from the information on the net it looks like there are two main units - pixels and points. Point is 1/72 inches so 1 pixel = 1 point at 72 dpi. At 96dpi (our tablet or any MS Windows OS in normal configuration) 1 point is 1.33 (or 4/3) pixels so 12 points = 16 pixels. On tablet this should produce 480/16=30 lines. The mystery is that Dejavu font at 12 points gives me only 25 lines + some tiny space like 2 pixels. And same happens for Courier New copied from Windows. This would mean pixel height for those fonts is slightly more than 480/25=19.2, why?. As for Dejavu/Vera fonts and other scalable fonts in general - they are great but IMO at small sizes nothing can beat bitmap fonts.

Hi All,
I'm facing a strange problem while using GTK+ Dialog box
I've used two dialogs one in IF and other in ELSE
if (some condition)
{
GtkWidget *dialog1 = gtk_message_dialog_new (main_window,
GTK_DIALOG_DESTROY_WITH_PARENT,
GTK_MESSAGE_QUESTION,
GTK_BUTTONS_YES_NO,
Send file to server %s?,
filename);
result = gtk_dialog_run (GTK_DIALOG (dialog1));
gtk_widget_destroy (dialog1);

Download file %s?,
filename);
result = gtk_dialog_run (GTK_DIALOG (dialog2));
gtk_widget_destroy (dialog2);
}
However if I use just a single dialog box at a time, everything works fine.
I've used gdk_threads_enter() and gdk_threads_leave() whereever
possible. these dialog boxes are created on 'select' event of CList so i
cannot use gdk_threads_enter() and gdk_threads_leave().
I need to have few more dialog boxes, but using only 2 is causing
problems of application crash.
Can anybody address this issue?
I didn't really get what the actual problem here is, but some advice
that might help:
* Unless you really, really know that you need to use threads, you
probably don't... using threads to get basic UI working is almost
certainly a bad idea.
* gtk_dialog_run() makes the dialog modal, so you can't use several
dialogs at once. You'll have to connect to the respose signal and
and show the widget yourself.
HTH,
Jussi

Giacomo Tufano wrote: http://en.wikipedia.org/wiki/Em_(typography) have, probably, the informations you're looking for. The answer to the Frantisek problem is, IMHO, that (citing the page) In digital type, the relationship of the height of particular letters to the em is arbitrarily set by the typeface designer. However, as a very rough guideline, an average font might have a cap height of 70% of the em, and an x-height of 48% of the em. These differences could account for the numbers Frantisek found... Thanks. So one basically cannot guess how many lines will fit from the point size alone, it depends on specific font and its designer. Quite confusing but nevermind :-) As for the first mystery - I found the solution. vte-0.12.2/src/vte-private.h #define VTE_PAD_WIDTH 1 When changing to 0 and rebuilding libvte4 it fits. Sadly same constant is used for padding width and height which is pretty unfortunate. Left border padding would be nice, without border there is no space and letters touch black LCD border and look a bit strange. Top and bottom border doesn't look so bad. I think splitting VTE_PAD_WIDTH into VTE_PAD_X and VTE_PAD_Y would be useful. And making it variable would be event better. Both for user customization and for computing it at runtime for proper centering when font size doesn't fit exactly.

[Announce] Release of the DCCP Plugin 0.7 for GStreamer
Hello list! I'm pleased to announce the version v0.7 of the DCCP GStreamer Plugin. Please, let me know if you have any problem on running the plugin, suggestions and improvements that you provided for it. The main news for this release is that the plugin can now support multiple connection in the server element and share the same sockid between to GStreamer elements. What is GStreamer? == GStreamer [1] is a library that allows the construction of graphs of media-handling components, ranging from simple Ogg/Vorbis playback to complex audio (mixing) and video (non-linear editing) processing. Applications can take advantage of advances in codec and filter technology transparently. Developers can add new codecs and filters by writing a simple plugin with a clean, generic interface. GStreamer is released under the LGPL. What is DCCP? = The Datagram Congestion Control Protocol (DCCP) [2] is a transport protocol that provides bidirectional unicast connections of congestion-controlled unreliable datagrams. DCCP is suitable for applications that transfer fairly large amounts of data and that can benefit from control over the tradeoff between timeliness and reliability. It is a message-oriented transport layer protocol that implements reliable connection setup, teardown, ECN, congestion control, and feature negotiation. It was published as RFC 4340 by IETF in March, 2006. Linux had an implementation of DCCP since version 2.6.14 and this continues to improve with each release. The latest official version of the DCCP code can be found at [3] and at [4]. What is DCCP Plugin for GStreamer? == It is a plugin that allows transfer data over the network via DCCP for GStreamer. According to all the tests that we proceeded, the plugin is able to stream audio files, such as mp3, audio captured from the microphone and raw data files. CHANGELOG = - Setting the default format of the source elements (dccpclientsrc and dccpserversrc) to GST_FORMAT_TIME. We use the function gst_base_src_set_format. - Configure source elements to automatically timestamp outgoing buffers based on the current running_time of the pipeline. We use the function gst_base_src_set_do_timestamp. We test if the gstreamer installed is 0.10.15 or more to use this function. - Code refactor - Adding gtk-doc to the elements TODO List = - Improve the implementation of the send mechanism adding the Paraslash solution based on queue - Improve the send mechanism to support the new feature of dccp in the linux kernel that allows application to get the packet sequence number. How to contribute? == Please, contact me at leandroal [at] gmail [dot] com Where is DCCP Plugin? = The DCCP plugin for GStreamer is under version control of the E-Phone. The E-Phone (Embedded-Phone) project aims to develop a VoIP client for Maemo platform based on DCCP transport protocol. In this project we are also implementing the CCID-4 [5] IETF drafts on the linux kernel.

Is there any application examples? == Yes, refer to the examples_app directory of the source file. Requirements - Linux Kernel with DCCP enabled (see [6]) - GStreamer - Additional GStreamer Plugins to make the example app works Best regards, Leandro.
