about textview (gtk_text_buffer_insert_with_tags cause segmentaion fault)
Hi all ,
When I insert some text to textview in a thread in the following
code(myThread::run) . it will segmentation fault .
Could someone help me to fix this issue.
Any comments and suggestion will be welcomed.

Problem writing pixels to GdkPixbuf data buffer
Hello. I encounter a strange problem when I'm writing image data to the GdkPixbuf data buffer. I create an empty pixbuf and get the data buffer. Then I use: pixel = pixbuf_data + i * n_channels , where pixel is a pointer to the pixel, pixbuf_data is the pixbuf data buffer, i is a counter in a for loop with a condition: for (i = 0; i width*height; i++) This for loop should iterate throught all pixel in the image. The n_channels variable is 4 because I use a RGBA pixbuf. When I have this pixel pointer, I use pixel[0], pixel[1], pixel[2] and pixel[3] to modify the RGBA values. I then handle the expose-event, create a cairo surface using the GdkPixbuf and display the surface onto the drawing area. The problem is when I display the pixbuf the image is shifted to the right for exacly two pixels. Meaning the first two pixels in the upper left are two places to the right, making the last two pixels of the row appear in the second row. I hope you understand. Am I making something wrong when writing data to the pixbuf? Or is there any other explanation. Please help.

If you use C++ and plain GTK, supposing you are initializing your callback
in the you should do something like this:
class MyClass
{
GtkWidget *mywidget_;
static void handle_click_cbk(GtkWidget *mywidget_, MyClass *data) {
data-handle_click(); }
void handle_click(); // your real callback
public:
MyClass() {
mywidget_ = gtk_button_new();
g_signal_connect(mywidget_, clicked, GCallback(handle_click_cbk),
this);
}
};

gtk_widget_modify_style( widget, style );

do it on created

I couldn't find any example on the net. I
understand that I dont have the reference to the labels...
, but when gtk refresh the screen needs the reference to
the labels...
So how to get the reference pointer or directly how to
change the font size on these objects ?
I have custom labels with my widgets...
Now, I'd rather change as less as possible the
Glade code (Glade use _with_label in generation code).
I think that would be better using with_label than a
custom button (I'm not completetly sure about it on
gtk).
Could any body give me some help about this problem? I
need to solve it
Why don't you use pango markup?
button = gtk_button_new();
label = gtk_label_new();
gtk_label_set_markup(GTK_LABEL(label), span
size='large'A/span);
gtk_container_add(GTK_CONTAINER (button), label);

Re: Problem writing pixels to GdkPixbuf data buffer
2008/7/15 Luka Napotnik [EMAIL PROTECTED]:
Hello.
I encounter a strange problem when I'm writing image data to the
GdkPixbuf data buffer.
I create an empty pixbuf and get the data buffer. Then I use:
pixel = pixbuf_data + i * n_channels
, where pixel is a pointer to the pixel, pixbuf_data is the pixbuf data
buffer, i is a counter in a for loop with a condition:
for (i = 0; i width*height; i++)
This for loop should iterate throught all pixel in the image. The
n_channels variable is 4 because I use a RGBA pixbuf.
When I have this pixel pointer, I use pixel[0], pixel[1], pixel[2] and
pixel[3] to modify the RGBA values.
I then handle the expose-event, create a cairo surface using the
GdkPixbuf and display the surface onto the drawing area. The problem is
when I display the pixbuf the image is shifted to the right for exacly
two pixels. Meaning the first two pixels in the upper left are two
places to the right, making the last two pixels of the row appear in the
second row. I hope you understand.
Am I making something wrong when writing data to the pixbuf? Or is there
any other explanation. Please help.
Greets,
Luka
Luka,
You should change this to something like this:
pixel = gdk_pixbuf_get_pixels(pixbuf);
rowstride = gdk_pixbuf_get_rowstride(pixbuf);
for(y=0;yheight;y++) {
for(x=0;xwidth;x++) {
/* do something with 'pixel' */
pixel += n_channels;
}
pixel += (rowstride - n_channels*width);
}
Rowstride can be something other than n_channels*width, which could
cause problems similar to what you're describing.

I tried porting this piece of code to PyGTK and while it works for the
most part one thing that jumps out is that, if the widget in question
has a tooltip, the tooltip does not show up at the pointer location but
rather in the top left corner of the screen.
One difference between this code and the PyGTK version is that PyGTK
insists on e.subwindow to the a GdkWindow instance (gtk.gdk.Window). I
am setting e.subwindow to windowUnderMouse (which seems to make sense
since it is the window that was entered or left) but I am not sure
whether that creates the problem with the tooltips.
Any input?

Getting a Column Number
Anyone? The following will get me the Column from a treeview, but from focus_column I don't know if I'm in the first, second, third . . . or last column. GtkTreePath *tp=NULL; GtkTreeViewColumn *focus_column=NULL; gtk_tree_view_get_cursor(GTK_TREE_VIEW(treeview), tp, focus_column); How do you get the column number from a GtkTreeViewColumn pointer? Is there a way to get the previous and/or next Column or column number? Thanks, Dave ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

First read gtk tutorials. Then compile, run and modify some gtk samples, just so you get into how gtk works. Then you can read the sourcecode of other gtk applications to understand how a 'big' application is structured. And then, if you have a specific question about for example how to create a custom widget, or how to list available wireless networks, you can get back to this mailinglist and ask it. tom ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
