Vector Images and GTK
Hello everybody, I am developing a GTK application in FC3 linux. The images for the application are provided by the client as WMF formats. As this application will be dynamic i have to include those files as it is. I heard that vector images like WMF gets rasterized when opened in GIMP. Is that what happens also in the application when we include vector images in the application using gdk_create_xpm? If yes, then how can we render the vector images as it is for the images are dissized that is the image seems different (as if x or y dimension has been increased) when displayed thru the mentioned function? Please anyone help me i got to complete this project within two weeks.

Attach objects to text in GtkTextview
Hi, I'm using a GtkTextView to display some text. Now what'd I'd like to do is to attach some extra informations to words. For example attach a file's uri to a particular word (like a link in web browser). I could attach a GtkTextTag to a word, but then I would need to create one different TextTag for every word (as most words would have different links). Anyone got any idea how I could do this?

A question about GtkUIManager
Title: A question about GtkUIManager
Hi,
I have a question regarding GtkUIManager. Documentation for the ui property of GtkUIManager says
The ui property
ui gchararray : Read
An XML string describing the merged UI.
Default value: NULL
However, it seems that's not true. Below is the test case and its output.
#include gtk/gtk.h
int main (int argc, char* argv[])
{
GtkUIManager *ui_manager;
gchar *ui = NULL;
gtk_init (argc, argv);
ui_manager = gtk_ui_manager_new ();
g_object_get(G_OBJECT(ui_manager), ui, ui, NULL);
if (ui)
g_printf (%s, ui);
return 0;
}
** Output **
ui
/ui
Is this a bug? Or the documentation means the stuff that actually matters between the ui tags is an empty string? If so, is this a gtk-doc bug?
Thanks
Yong

I don't know of any plans for this. I don't think networking makes a whole lot of sense in glib, and these libraries being separate is less harmful than the other libraries. Except that having them separate makes it more likely for an app developer to use the underlying system APIs which makes their app less portable. If we put this in glib, we tell the ISVs to use this API which will make their app more portable.

A few more random thoughts: - Zooming is more than just setting a transformation matrix because the reason you want to zoom is to see more details. So somehow a model needs to be aware of how much detail should be drawn. Text is extra tricky here. Do you want zooming to show you more text, or do you want it to make the font larger. Even if you choose to just make the font larger the text object won't scale linearly with the magnification, because of font hinting etc. I guess you could avoid this by always rendering text unhinted, positioned using non-device coordinates, but this will cause pretty unreadable text. You can not simply favour one over the other. I guess an application like Nautilus would benefit from the first option (show more text), while Dia (or Gaphor) would benefit from the second: Having text well readable at a 100% zoom factor, and having unreadebly small text at say 400%. I found it pretty hard myself, getting the text and font stuff right (with DiaCanvas), especially text editing. Having good support for font and text handling is really a must.

Re: Announcing: Project Ridley
Hello all, I don't really see much reason ever to break ABI for the forseeable future. There's essentially nothing stopping us from simply leaving deprecated functions in there indefinitely, other than a fairly minor memory footprint increase which will never be paged in anyway. This is an issue for embedded systems using gtk (like for example GPE). Maybe a --disable-deprecated flag could do the trick? This will also enable other people developing with gtk to test their code before the ABI gets changed (I would not say broken). (the last thing could also be done with a deprecated macro that warns during compilation as done in the Linux kernel) And it would reduce the memory footprint on disk / flash / you-name-it. Ram is indeed less of a problem. Also looking at the number of functions I see marked as deprecated this is could be more than a minor increase.

Defining your own new input methods?
Inquiry: Definining your own new input methods? Over a year ago I managed to write some new Simple Composing Input Methods for GTK+, and get them installed (by piggybacking them into gtk-im-extra). I managed to get them working and selectable from within gedit, but it was all more painful than it ought to be. I'm starting to experiment with gedit and Unicode input methods again. Could some kind guru please summarize the status of Defining and Installing Your Own New Input Methods for GNOME/GTK/gedit? 1. Are documentation/tutorials now available? 2. Simple Composing Input Methods are really too simple for my needs. They allow you to specify a sequence of Key Presses that constitute an input sequence, and each input sequence must map to a _single_ Unicode character output. I need to define input methods that map a sequence of one-or-more Key Events (where Key Events includes information about which modifier keys, if any, were pressed) to one-or-more Unicode character outputs. There might be one-to-one, many-to-one, one-to-many, or many-to-many. What's the current format/API/recommendation for defining such input methods for Gnome/GTK/gedit? 3. Has the input-method installation procedure been simplified? To install a new Java Input Method, you simply copy it into the Extensions Directory of your Java installation. That makes it visible to all Java applications. When you launch a Java application, you can also using the -D command-line flag to specify a PATH (directory, or set of directories) where the applications should look for extensions (input methods). Similarly, to install a new OS X input method, you simply place it in one of several designated folders (including your own personal folder for input methods). It would be welcome news to learn that installing a new input method for GNOME/GTK/gedit was just as easy.

idea: g_alloca_printf
hi, a little brainer for everyone who fells like having a look at it. At pattern that can be found in many glib based app is: gchar *status=g_strdup_printf(_(Loading file \%s\),file_name); g_object_set(G_OBJECT(self),status,status,NULL); g_free(status); This has the advantage that it framents memory with small strings. When e.g. serializing xml it can matter. A solution is: gchar *status=g_alloca(strlen(_(Loading file \%s\))+strlen(file_name)-1); g_sprintf(status,_(Loading file \%s\),file_name); g_object_set(G_OBJECT(self),status,status,NULL); This is using g_alloca(). A good side-effect is, that one can forget to free it ;) Unfortunately it not nice to write it this way. The idea now is to wrap it all in a macro (needs to be a macro, as alloca only work localy). In the end I'd like to do: g_object_set(G_OBJECT(self), status,g_alloca_printf(_(Loading file \%s\),file_name), NULL); First try: #define g_alloca_printf(str,format,...) \ (sprintf((str=g_printf_upper_bound(format,args)),format,...),str) * how to get from '...' to 'args' * passing 'str' as a param is not nice Any ideas folks?
