Storing images in GtkTreeView model
Im using a GtkTreeView with a GtkListStore to display a list of rows with both text and a picture. I can declare the model with just the text as follows: /lhs_store=gtk_list_store_new(1,G_TYPE_STRING,); //1 cols(string) / but how do I decalre it to have a picture as well e.g the following- which doesnt work. What type do I use for the second col? /lhs_store=gtk_list_store_new(2,G_TYPE_STRING,G_TYPE_PIXBUF); //2 cols, 1st is string, 2nd is icon/ I can then add the text to the model easily with: /gtk_list_store_set(lhs_store,&lhs_treeiter,0,"Subscribers",-1); //put string in col0/ what I also want to do is put an image file in the other column I know how to set up a pixbuf renderer in the view to display it but I cant find an example showing how to store images in the model. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

I suppose you mean GtkTreeView. I can find examples for toggle buttons but I want a standard button in each row. No, that's not available and it is possible either, namely because GtkCellRenderer has a relatively limited interface and do not receive all events that are necessary to simulate a GtkButton. You can write a cell renderer that will respond to clicks (or find an already written one, people have done this) but it will not behave like a real GtkButton.

Problem swapping GtkScrolledWindow contents on the fly
The following function is called to display a vbox, which is read from a
glade file, in a scrollview.
If the vbox or 'page' hasnt been displayed before then
generalpageinitialised will be false.
There are other 'pages' in the app which are vboxes read from a glade
file in the same way. The app always shows the vbox called rightpanevbox
and it swaps this variable to point to the appropriate one read from glade.
The first time the function is called the page shows perfectly. The
second time I get errors such as:

Re: Problem swapping GtkScrolledWindow contents on the fly
Thanks Tristan. I think I follow what you're saying... The call to gtk_container_remove is decrementing the ref count so generalpage becomes NULL? Is there a way to "up" the count immediately prior to calling gtk_container_remove Tristan Van Berkom wrote: Ahh you mean it shows up and everything the first time, I see. I think you are missing a reference to the generalpage widget. Its initially built as a floating, and then the floating reference is "sink"ed the first time you add it somewhere, when you remove it the first time; its destroyed because you dont have a reference.

I thought it was probably gtk_widget_ref but although that has cleared
the warnings the widgets dont display themselves the 2nd or 3rd time the

Re: Problem swapping GtkScrolledWindow contents on the fly
Still getting strange results with this. Ive posted a skeleton app at www.simple.org/TCSAdminGTK.tar which is a single source file which can be comiled with g++ ./main.cpp `pkg-config --cflags --libs libgnome-2.0 libgnomeui-2.0 libglade-2.0` When you click one of the options on the left the contents changes on the right. At present only 'General' and 'Calls' are implemented. As you can see the first time you click one of these the widgets show correctly but the second time you click it they don't but you get no error on the console either. The guts of the issue are contained in the functions showGeneralPage() and showCallsPage() The closest explaination Ive been able to find is that the call to gtk_container_remove (GTK_CONTAINER (rightpanescrollview),gtk_bin_get_child(GTK_BIN(rightpanescrollview))); is deleting the widgets as well as just removing them from the container, but theres no error to suggest this, and I would have thought the calls to gtk_widget_ref(callspage) or gtk_widget_ref(generalpage) would have prevented this.

Re: Detecting Ctrl Esc in GTK app
How would you link it directly to the window then rather than to a widget? As far as I can see you need to associate it with a signal, but looking down the list of signals for windows I cant really see one suitable, hence I was using this: gtk_widget_add_accelerator(quitbutton,"clicked",accelgroup,GDK_Q,GDK_CONTROL_MASK,GTK_ACCEL_LOCKED); g_signal_connect(G_OBJECT(quitbutton),"clicked",G_CALLBACK(handleControlQ),NULL); Im using Ctrl Q for the time being as I havent worked out how to set it up for Esc yet. The reason for doing this is Im writing an app for a public kiosk which will take over the whole screen and not provide any way for the user to exit the app. The admin will press Ctrl Esc (or Ctrl Q for the moment) which will pop up a dialog for a password to exit the app. On 30/08/11 14:19, jcup...@gmail.com wrote: Hi Andrew, You can add an accelerator to a window and it'll be called when that key combination is pressed. It doesn't need to be associated with a widget. However I think it's generally considered good form to have a menu item somewhere with the accelerator as a shortcut.
