	Glade, GTKMM, and adding widgets to containers that are created in Glade. by Steve Scott-3 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Hi, Is there some trick to adding hand coded widgets to containers that were in created in Glade. In other words I have a ScrolledWindow created in Glade and in code I have created a TreeView (and model). No matter what I try I am unable to see my TreeView appear in my GUI. From all the examples I have found this is how it is supposed to work in this case: m_refGlade->get_widget("myscrolledwindow", m_myScrolledWindow); // get my glade defined ScrolledWindow Widget m_myScrolledWindow->add(*m_myTreeView); // add my TreeView Widget to the scrolledWindow. (and yes the Treeview has a listmodel) m_myTreeView->show(); // update the GUI Can someone tell me what I am doing wrong?

Here is some informatin about its use with Gtk::Builder though it was much the same with libglademm: http://library.gnome.org/devel/gtkmm-tutorial/unstable/sec-builder-using-derived-widgets.html.en -- murrayc@... www.murrayc.com www.openismus.com _______________________________________________ gtkmm-list mailing list gtkmm-list@... http://mail.gnome.org/mailman/listinfo/gtkmm-list

I have used the derived widget for my main window, and that works fine, but is this the only way to add widgets to Glade containers?

I have used the derived widget for my main window, and that works fine, but is this the only way to add widgets to Glade containers? Thanks, Steve I went back and derived a ScrolledWindow Class ( m_refGlade->get_widget_derived("myscrolledwindow",myscrolledwindow); ). Then inside that class I created the tree and the model, and added the tree it to itself. And sure enough it worked.... Now my question is how come I have to derive a container to add to it? I should be able to manipulate any widget from glade with the standard m_refGlade->get_widget right? Hopefully someone can shed some light on this.

You can add widgets to glade-instantiated containers just as you can add them to containers instantiated in any other way. Just call the relevant method, such as add(), pack_start(), etc. In practice, you will then want to have a placeholder container in the Glade file into which you will place your special widget. -- murrayc@... www.murrayc.com www.openismus.com _______________________________________________ gtkmm-list mailing list gtkmm-list@... http://mail.gnome.org/mailman/listinfo/gtkmm-list
	Re: Glade, GTKMM, and adding widgets to containers that are created in Glade. by Steve Scott-3 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Thats what I tried before I used the derived widget option of Glade. As I wrote before: m_refGlade->get_widget("myscrolledwindow", m_myScrolledWindow); // get my glade defined ScrolledWindow Widget from glade m_myScrolledWindow->add(*m_myTreeView); // add my TreeView Widget to the scrolledWindow. (and yes the Treeview has a listmodel) m_myTreeView->show(); // update the GUI For whatever reason my tree would never display. Once I used a derived widget it worked. So i ended up creating a derived ScrolledWindow in which I placed my tree into. I am with you. I would have though either way would work, but it doesn't. Unless I am missing something. ScrolledWindow does not have a pack_start.

ScrolledWindow does not have > a pack_start. It should work, though you would see a warning on stderr if the scrolledwindow already had a child widget (it may only contain one). A simple test case might make things clearer. I wonder if this has something to do with the Viewport that gtkmm's ScrolledWindow::add() automatically adds to ScrolledWindows when needed by the particular type of child widget. -- murrayc@... www.murrayc.com www.openismus.com _______________________________________________ gtkmm-list mailing list gtkmm-list@... http://mail.gnome.org/mailman/listinfo/gtkmm-list

I even added a Viewport to the ScrolledWindow in glade even though I don't have to with a TreeView widget, and got the same result. As I get farther in my program, I am going to try different containers( like a vbox ro hbox) to see if i get the same results. If I don't then there's something wrong with the scrolledwindow. I will report back if I find something. Thanks for all your help.
