Re: sprintf and clists
gchar buffer[1024]; static gchar *cclist[1]; sprintf(buffer, %d, some_dumb_int); cclist[0] = strdup(buffer); gtk_clist_append(GTK_CLIST(clist1), cclist); This is assuming you have a 1 column clist. check out if the string is '\0' terminated. best initialize it after the declaration with memset(buffer,'\0',1024); I don't think you need to check for the '\0' as the buffer is large enough to hold an integer. An integer might be at max 32bits, so for an unisgned int, approx. 4 000 000 000 (4 billion) or 4.0e9. So there is a maximum of 10 digits or caracteres. As the buffer is 1024 large, it is surelly big enough not to risk to have a buffer overflow. BTW wouldn't it be enough to use a buffer of size sizeof(int) ? No you cannot do that. Sizeof(int) give the size in octet allocate for one integer, depending on the compiler and the machine, it might be 2 or 4 octets. If you declare your buffer as sizeof(int), then at max you have a table of 4 caracteres. So you cannot put 1000 for example into such a buffer, it's too big number (it's 4 digits! so there is no place left for the '\0') Jean-Christophe ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
Visible size of GnomeCanvas
Hello, We have a GnomeCanvas set to a size larger than the window. The user uses the scrollbars to move the canvas and see the hidden parts. For a certain purpose, we need to know the size of the visible area (the area which is currently visible within the border of the window). How to get this size? We packed the Canvas inside a ViewPort which is inside a scrollwindow. Maybe the information can be retrieved from one of those parents? Any help would be greatly appreciated, Best regards, --- Jean-Christophe Berthon ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list

Re: Getting a nultiple selection from a CList
Hello Neil,
When you are in MULTIPLE SELECTION mode, you can select multiple row by just
clicking then one after one. And if you don't want anymore one row, just
click on it. It doesn't use the ctrl and shift button!
If you want it to be like under windows explorer, by using shift and ctrl,
to select group or individual files, then you should set the mode to
EXTENDED SELECTION. It is also about multi-selection!
Best regards,

Thanks for the information.
Now I have one more question related to this. I have activated
GTK_SELECTION_MULTIPLE on the CList in question. However, when I try to
actually do a multiple selection (mouse + shift or ctrl), nothing
happens. Is this behavior not built in? If not, then how can I create
it??? Thanks.

Re: Window size
Did you try this :
gdk_window_resize (GdkWindow *window,
gint width,
gint height);
To get the GdkWindow object of your Widget, just do it that way :
GTK_WIDGET(MyWindow)-window
(N.B. if MyWindow is a GtkWidget* then you don't need to cast it with
GTK_WIDGET, simply write : MyWindow-window)

Hi all,
I'm walking through gtk 1.2 doc since 1 or 2 hours and I can find a

gtk_window_set_geometry_hints don't works, gtk_window_set_default_size

Re: Window size
gdk_window_resize (GTK_WINDOW(MyWindow-window), width, height); (becauseMyWindow-window IS a GtkWindow). Then if your window is a GtkWindow object, you should cast it : gdk_window_resize(GTK_WIDGET(MyWindow)-window, width, height); Respect the parenthesis as you need to cast your GtkWindow object in a GtkWidget one. And once you casted it, you can access the window property of your GtkWidget which is the GdkWindow corresponding to your object (take care I said gDkwindow...) And it don't work ... :(( maybe written like above, it is going to work :-) Don't know if the fact that I don't use a gtk_main() or gtk_loop() or something change something, I think gdk_flush() do the work. ??? I'm not understanding you... a window is typed as a GtkWindow is most of the cases I think, no ? :) Well, I'm using only GtkWidget object, that I'm casting to the right type when needed, so I find my data structure more coherent.

SegFault with GnomeCanvas (Polygon)
Hello, When using the Polygon item in a GnomeCanvas (with the aa option ON : it's about using libart instead of GDK to draw, I think...) we are getting a segmentation fault after having changing a few times the fill and borderline color of this object. We are changing the colors each time the user select a polygon. We are using the following code to create and change the color of a polygon : gtkRoot = gnome_canvas_root(GNOME_CANVAS(cnvDrawableObject)); gtkPoints = gnome_canvas_points_new(4); gtkPoints-coords[0] = (ast_double)aPointPxlBG.lX; gtkPoints-coords[1] = (ast_double)aPointPxlBG.lY; gtkPoints-coords[2] = (ast_double)aPointPxlBD.lX; gtkPoints-coords[3] = (ast_double)aPointPxlBD.lY; gtkPoints-coords[4] = (ast_double)aPointPxlHG.lX; gtkPoints-coords[5] = (ast_double)aPointPxlHG.lY; gtkPoints-coords[6] = (ast_double)aPointPxlHD.lX; gtkPoints-coords[7] = (ast_double)aPointPxlHD.lY; gtkGfxItem = gnome_canvas_item_new ( gtkRoot, gnome_canvas_polygon_get_type(), points,gtkPoints, fill_color_rgba, 0xAFCAE980, outline_color_rgba, 0xAFCAE9FF, width_pixels, TAGR_LINE_WIDTH, NULL ); And to change the color : gnome_canvas_item_set ( gtkGfxItem, fill_color_rgba,iFillColor, outline_color_rgba, iOutlineColor, NULL ); /* With iFillColor and iOutlineColor two gint32 numbers representing the selection color */ After a few selection (about 1à different ones) we're getting a segmentation fault when executing the change color `gnome_canvas_item_set' NB: If I change the item for another form (rectangular or ellipse have been tryed) there is no problem! Why we are not changing to those items is because it will not represent anymore what it should be, we need to use polygons.

Re: SegFault with GnomeCanvas (Polygon)
1) how big are your polygons? 2) which version of libart? 3) do you know how to use gdb? reporting a segmentation fault is not particularly useful by itself. either use gdb to get a backtrace so you can see precisely what goes wrong, and/or produce a little test case on the order of 100 lines or so. Hy Paul, First thank you for your reply :-) 1) Do you mean if they are pentagons, hexagons, or bigger? In fact I'm displaying quadrilatere (4 sides polygons), I cannot use rectangle are I don't have always a rectangular angle and it can be looking sometimes a bit trapezoid or parallelogram-ish... They are about a 100 pixels wide for 50 heigth. 2) I'm using libart_lgpl 2.2.0 -- Gtk 1.2.10 -- Gnome 1.2.13 3) I don't have debug feature for Gtk/GNOME so the only thing I know is that I'm getting seg-fault (and no core dump) on the call of gnome_canvas_item_set.

Checkbox and Style
Hello, I have another problem which is how to change the state of a checkbox to Partially Checked. Explanation: The user select a column. Each data in this column can be TRUE or FALSE. So if a column contain only TRUE rows, then a checkbox should be Checked, if it contains only FALSE then it should be Unchecked and finally if there is a mix of TRUE and FALSE the checkbox should be Partialy Checked. I've seen that behaviour under a few application, where when it was checked, there was a black V drawn on the button of the checkbox, when unchecked the V was cleared, and when partially cheked, the V was grey-ish. I've tryed using the fg fields of the Style of the checkbox, but it had no effect! It seems that Gtk is using a picture to draw the checkbox. How can I do it?

CList column auto-resize (on demand)
Hello, I would like to "auto-resize" the column on demand. I'll be using a combination of gtk_clist_optimal_column_width (to get the width of my column) and gtk_clist_set_column_width (to set it). I want to have this feature working like on most spreadshits : double-clicking on the line separating 2 columns will auto-resize the left column. I didn't find any relevant signal to bind this feature to. I've looked in the gtk_clist.c source file and it seems that they are using internal properties of the clist to do the job and binding the signal button_press. In the source they do something like that : in the button_press callback /* This code is extract from gtkclist.c of the Gtk+ 1.2.10 source code */ /* It is extract from the handler of the button_press event for (i = 0; i clist-columns; i++) if (clist-column[i].resizeable clist-column[i].window event-window == clist-column[i].window) So they are testing for each column if it is resizeable AND if it has its own gdk_window set AND if the gdk_window involved in the event is the same as the column one. I can do the same test on a customized button_press event callback that I will attached to my clist widget instance, and do the trick. But I find it unsafe because I'm using internal data. Do you know of any better way? I hope I've been clear enough.

Re: why that not working?
Hello :-)
This is not working because cyan means that you give the address of the
variable cyan which then should be declare somewhere.
gdk_windows_set_background require as a second argument a pointer to a
GdkColor structure. To allocate this structure you need to declare a
GdkColor object. You can do that :
GdkColorxMyCyanColor;
Now to fill up this structure you can use to ways. Or you set the red, green
and blue color manually (take care each of this three properties as a value
from 0 to ~65535) like in the example I send before or you use a string like
cyan or red with this function :
if (gdk_color_parse(cyan, xMyCyanColor))
{
/* The color is created (enough system ressource) */
/* So now you have to allocate it to the colormap in order to use it */
gdk_colormap_alloc_color(pxColorMap, xMyCyanColor, FALSE, TRUE);
/* See my previous email on how to get a colormap */
}
else
{
/* Error not enough system ressource... (well I guess that's the reason
or
the color doesn't exist, for example you put hello for the color
;-) */
}
I hope, I'm clear enough. If you need other help, just ask me :-)
PS: btw I'm not sure if you then need to free the color. I just saw that
there is a gdk_color_free function in the API. Maybe someone-else can help
us about that!

Re: Gtk Window
You have to set your window _Modal_ to block access
of other window. But to stop the execution of the code, I don't know if there is
a Gtk implementation of it. I'm doing this solution. I have a boolean that is
initialized to TRUE when I'm showing the modal window and then I have the
folowing code :
while ((gtk_events_pending()) ||
(bDlgInfoState_X ==
TRUE)){gtk_main_iteration();}
This loop process the gtk-event, so the modal
window respond to user interaction. And as soon as the modal window is hidden,
bDlgInfoState_X is set to False, so I'm exiting this loop.
Hope this help :-)

Re: Fw: g_log () Non fatal warning
I also did a simple wrapper that encapsulate malloc and do kind of trace, but I would rather use g_malloc instead of malloc and use the maybe better memory check of the glib. Anyway if I can't change it, art least I know, thank you :-) I'll try to improve my own memchecker so. Thanks a lot :-) Hi Jean-Christophe, Unfortunately I don't think this is possible. You can use g_log_set_fatal_mask() to say which sorts of errors are fatal, but G_LOG_LEVEL_ERROR is always set fatal whatever you do. I think this was decided because for a GUI library, it's very hard to recover reliably from out-of-mem errors. If you use glib for something else, of course, this may not be the right decision. I have an image processing library which uses glib ... but I had to make my own malloc() wrapper, as I needed to be able to recover from out-of-mem errors.

Re: Fw: g_log () Non fatal warning
you might consider using glib-1.3.x which allows you to plug your own memory handling system into glib and use it through g_malloc() and friends. glib-1.3.x also has g_try_malloc(). That's look interesting but I'll wait for glib-1.3 to be released stable (in a futur 1.4 or 2.0 version) to implement it. Thanks for the tip, I'll think of it when porting my actual version.

Re: gtk_object_unref
Jean-Christophe Berthon [EMAIL PROTECTED] writes: (I've read some older threads about it - like the one about the container - but in my case my objects and points are drawings on a gtk-canvas and I want to ref and unref some of the GtkCanvasItem that are shared...) I hope I've been clear enough, if you need more explanation, tell me what you didn't understand and I will try to say it differently. Say you create the canvas item to give it to object A - do you also reference it? first thank you all for your answers. Yes you right I didn't reference it. If not, then you are assuming ownership of the floating reference, which isn't allowed. The canvas will then strip the floating reference off the item when you add the item to the canvas; and object A will end up not owning any reference at all. If you do this: obj = whatever_gtk_object_new (); Then the immediate situation is that obj has one floating reference, and zero owned references. To remove the floating reference, do this: gtk_object_sink (obj); That will finalize the object if it hasn't already been finalized. What the canvas does is this: gtk_object_ref (obj); gtk_object_sink (obj); So then obj has one reference owned by the canvas, and zero floating references. Anyhow, short answer, you need another gtk_object_ref(), rather than taking ownership of the floating reference. No one can ever own the floating reference; if you want to call unref on a GtkObject, you must first call ref; there are no exceptions, even if you created the object yourself. OK. I didn't really understand everything (esp. about the floating reference, I don't exactly what this thing mean or is...). But I've tryed to add to my code a gtk_object_sink just after the creation of the canvas item. Then I've tryed to add instead gtk_object_ref and gtk_object_sink. And finally I've tryed gtk_object_ref only instead of the previous two commands. But in all this case I got the warnings. But I want to precise one thing. The unref operation occur in a callback of the canvas item. So one of them receive an action from the user and I have to unref this item and a second one (passed with the void* of the callback). The item that fired the event has a ref_count of 3 (instead I would expect 1) while the other one has a ref_count of 1 (which should be normal). I'm applying the unref to both of them, so after the unref execute there ref_count decremente of 1 (so respectively to 2 and 0). I'm getting a warning only on the second item but both are destroyed!!! (I guess this job is done when leaving the callback as at this moment I receive a second warning (again about this ref_count).) If you need I can send a extract of my code with all the involved parts. Again thanks all for your help, Have a nice day (or night)...

Re: About gtk_clist_set_row_data
Thank you Mohamed and Jim for your answers.
Well I didn't find that much info in the FAQ neither in the tutorial (they
say the prototype of the function should speak by itself... well not for
me!)
I was interested to see if I could post a structure with any kind of data
via this function. So after your answer, I've try on one of my GUI which
contain a CList (with 11 columns) to set up a structure and send it via
gtk_clist_set_row_data. It didn't succeed. I had about 10 fields with int
and one with char [] but nothing appear.
Here is a sample code of what I wrote :
GtkWidget *lstPA_ListOfPA;

essai.a = 1;
essai.b = 2;
essai.c = 3;
essai.d = 4;
essai.e = 5;
essai.f = 6;

essai.h = 8;
essai.i = 9;
essai.j = 0;
strcpy(essai.k, hello);
lstPA_ListOfPA = lookup_widget(aWindowsInfo_X.paIUPAData-wndPA,

Salut Jean
you can attach any type of data you want to the given row
simple example :
you want to attach a color name to each row :
8
static gchar *couleur[3]={vert,bleu, rouge} ;
for (i=0; i3; i++)
gtk_clist_set_row_data (clist, i, (gpointer) couleur[i]);
-8---
or attach some kind of data like
typedef struct {
gint myint;
gchar *mychar
}SomeStruct;
SomeStruct * data;
gtk_clist_set_row_data (clist, i, (gpointer) data);

I think you misunderstand what happens with gtk_clist_set_row_data - it
simple assigns a pointer to the clist row so that that pointer can latter
be
retrieved with gtk_clist_get_row_data. The data need not (and usually
does
not ) have anything to do with the number of columns in your clist.
It sounds like what you are trying to do is set or change the text that
appears on the displayed widget?

Hy everyone, Sorry to only reply now to this old post, but I have a question regarding the gtk_widget_destroy feature. For each windows, I'm puting code on the delete event to check if the data of the window have been modify and in this case displaying a dialog box asking the user for saving. If he push cancel, then I return TRUE and the widget is not destroy. This is working perfectly when the user click on the cross button (to close the window). But I put a close feature in a menu, and I was trying to use the gtk_widget_destroy function. The problem is that in this case the only event fired is the unrealize one. Which cannot stop the process of destroying the widget... Is that something normal (or standard) or is it a bug? I mean (thinking logical) if I destroy a widget I would expect the destroy event to be fired! PS: Anyway I found a workaround, on the close menu callback, I'm checking if the data is modifyed prior to call gtk_widget_destroy. But I don't find it a good solution as I have code duplicated now which is not a smart thing to do... And so I would prefer to find out why the behaviour of the gtk_widget_destroy is like that.

Re: GtkList number of items? gtk_object_set_data (GList)?
Well I just get into the same problem... (see one of my post, still waiting moderator approval) In fact with a GtkCList there is noway (official) to get the number of items or rows (well at least it is well kept in the other case...) So one bad way to get it is that : GtkWidget*clist; guintiNbItems; iNbItems = GTK_CLIST(clist)-rows; But I would advise you to encapsulate it (to make a function or macro doing this job)! So if you use it in many points in your code and in the future this call is not working. You just have to change it in one point, and the change will apply to all your program :-) Best regards, --- Jean-Christophe Berthon Cap Gemini -- Ernst Young Toulouse FR Skill Aerospace -- Image Quality Email: [EMAIL PROTECTED] Tel : (+33) 561 31 6639 - Original Message - From: Andrés Giraldo [EMAIL PROTECTED] To: Jean-Christophe Berthon [EMAIL PROTECTED] Sent: Tuesday, July 10, 2001 5:22 PM Subject: Re: GtkList number of items? gtk_object_set_data (GList)?

Re: GtkList number of items? gtk_object_set_data (GList)?
1) you should try : g_list_length
2) you should define a structure... I'm explaining it better.
Maybe you have now something like that (based on the idea that you have a
combo box behind...)
GList*list = NULL;
gchar*comboitem;
comboitem = g_malloc(sizeof(gchar)*20);
strcpy(comboitem, toto);
liste = g_list_insert(liste, comboitem, (GCompareFunc) compare);
strcpy(comboitem, tata);
liste = g_list_insert(liste, comboitem, (GCompareFunc) compare);
/* ... */
OK now you change it for this:
typedef struct _MyComboItem
{
gchar*pcItem;
gpointer*pvData;
} MyComboItem;
GList*list = NULL;
MyComboItem *comboitem;
comboitem = g_malloc(sizeof(MyComboItem));
comboitem.pcItem = toto;
comboitem.pvData = ComplementaryInfo;
liste = g_list_insert(liste, comboitem, (GCompareFunc) compare);
comboitem.pcItem = tata;
comboitem.pvData = ComplementaryInfo;
liste = g_list_insert(liste, comboitem, (GCompareFunc) compare);

Hy, I was looking at how to get the number of row of a CList, and I find out that this is not implemented. We can get the number of column via the args n_columns but nothing for the row. (I've looked in the source code of the gtkclist). So I find that in the _GtkClist structure there is a rows field which should maybe linked to a n_rows arguments? Or is it a mistake of conception of me? I know that in futur version, this component will be deprecated. So maybe nobody will work on adding such a feature.
