Re: Capture console app output into texview?
Hi,
thanks again for that hint. Unfortunately adding
/* switch to line buffered mode */
if(setvbuf(fh, NULL, _IOLBF, 0))
perror("setvbuf(_IOLBF)");
to the program posted by Dov doesn't change anything.
Are there limitations on changing the buffer mode? E.g.
only the transmitter side can do that?

Hi, i am trying to run a text mode application in the background of my gtk one and display its output in a textview.

How to do a graphic overlay?
Hi, i'd like to do some graphic overlay. In this particular case i'd like to put two buttons on top of a goocanvas. I tried to hook into the expose event and just draw something to the gdkwindow of the widget. That simply doesn't work. It works with a gtkdrawingarea, but not with the goocanvas. What can prevent me from drawing to the gdkwindow of a widget? I also tried to use a seperate window, but that's pretty difficult to handle since you e.g. have to move those windows when you move the main window etc etc. So just painting their seems simpler ... but unfortunately doesn't work Till ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Changing gtkstatusbar background color
Hi,
sorry to bother you again with a question. I am trying to set the background
color of a
statusbar. I have found several postings in the net indicating that this is
just a matter
of adding the statusbar to an eventbox and setting the background color of that.
However ... that just doesn't work. The following code shows a statusbar and
for a fraction of
a second i even see it having a red background. But after that it returns to
its default
color and stays that way. What am i doing wrong?
Thanks,

Re: Passing Struct to g_signal_connect
Hi,
you have to make sure that the parameters of your callback function
exactly match what's been described for this particular event. In your
case your have to check the "clicked" event for a GtkButton which gives
us:
void user_function(GtkButton *button, gpointer user_data)
So this is how your callback function should look like:
void on_button2_clicked(GtkButton *button, struct allStructs *by_ptr)
Your struct should be the _second_ parameter and not the first (any only)
one your made it. What you did is: You got a pointer to the GtkButton structure
of your button and used _that_ as a pointer to your own struct. You
are likely messing up the Button structure ...
This is one ugly thing with the C bindings and the fact that everything
is just casted by this G_CALLBACK() macro. That way the compiler isn't
able to check these things and errors like yours happen. And these can
be very nasty bugs since they cause people to write to memory they
are not supposed to write to. A classic door for hackers ...

Where to ask about gnomecanvas? (How to get all items via gnome_canvas_get_item_at?)
Hi, is this the right place to ask a question about gnomecanvas? I am using gnomecanvas for a mapping application (an openstreetmap editor for maemo). Sometimes items are stacked (e.g. a building is a polygon which may be placed in some some park which also is a polygon). The problem is that i need to get access to all things located on a position, but gnome_canvas_get_item_at only gives me only the top item. How do i get access to all items? The building in the example above may e.g. be drawn prior to the park and thus not be the topmost item and thus basically not accessible. I could of course re-order the items, but my program basically has no knowledge about buildings and the like. Everything is just a polygon (or a closed way in openstreetmap). So i wouldn't know which thing to order in which way. Till ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

coincidentally that's also a thing a needed for my program (a geocaching

And thanks for that routine, it works perfectly!
Still no hint for the textview. I really can't believe that there's nothing like
this in any tutorial. But all tutorials dealing with textviews inside a scrolled

Solved: How to make a gtktreeview column flexible?
Hi, in have solved this problem. Here's the answer for reference: Instead of using gtk_tree_view_insert_column_with_attributes to insert a column, one might use seperate calls to gtk_tree_view_column_new_with_attributes and gtk_tree_view_insert_column as this give us an explicit reference to the column. Thus one can use gtk_tree_view_column_set_expand(TRUE) on that column and voila ... the column scales nicely with the window width.

How to make a gtktreeview column flexible?
Hi, i have a gtktreeview filling the complete width of a window. Now i want the view to always use the full width. I therefore want the middle column (a text column) to be flexible. I want it to be as wide as possible for any given window width. So if you make the window wider i want this column to become wider. If i just enable ellipsis in the columns text renderer the column gets very small and only a fraction of the window width is used. If i make it a fixed width it's exactly that: fixed width. How do i make the column always use a much space as possible but never more than available?

Still the multi-textview in scrolled win in notebook problem ...
Hi, i am still fighting with a strange problem. Some things need to be combined to trigger it: - I have a tabbed notebook - One initially not visible (read: not the first) tab contains a scrolled win - Inside this win are mutliple textviews (or gtkhtml views) in a vbox or table - At least one of these texts contains a newline Then the textviews will initially not display the entire text but only the part up to the first newline in the text. Once i click into the text everything is corrected and the entire text becomes visible. If any of the above things isn't there (e.g. no notebook or not multiple textviews) everything displays fine. But if all four things come together the text is truncated after the first newline. This is even worse with a gtkhtml view as this isn't even updated if i cklick into the view. I have attached what i think is the shortest program demonstrating the problem. I am seeing this problem with gtk 2.12.0 under ubuntu as well as with gtk 2.10.12 under maemo/hildon on a n810. Please have a look at the attached example. Till ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
