    <p>I have a program which shows two <a href="http://developer.gnome.org/gtk/2.24/GtkTreeView.html" rel="nofollow noreferrer"><code>GtkTreeView</code></a>s packed inside a <a href="http://developer.gnome.org/gtk/2.24/GtkPaned.html" rel="nofollow noreferrer"><code>GtkPaned</code></a> (<a href="http://sscce.org/" rel="nofollow noreferrer">sscce</a>: <a href="http://pastebin.com/jzTT0zSA" rel="nofollow noreferrer">here</a>):</p> <pre><code>gtk_paned_add1(GTK_PANED(paned), tree_view1); gtk_paned_add2(GTK_PANED(paned), tree_view2); </code></pre> <p>The result is the following:</p> <p><img src="https://i.stack.imgur.com/bbbBM.png" alt="Window presenting the two tree views"></p> <p>However, the tables can become bigger, so I added then to <a href="http://developer.gnome.org/gtk/stable/GtkScrolledWindow.html" rel="nofollow noreferrer"><code>GtkScrolledWindow</code></a>s (sscce: <a href="http://pastebin.com/uW0EAvTS" rel="nofollow noreferrer">here</a>):</p> <pre><code>GtkWidget *scrolled_window1 = gtk_scrolled_window_new(NULL, NULL), *scrolled_window2 = gtk_scrolled_window_new(NULL, NULL); gtk_container_add(GTK_CONTAINER(scrolled_window1), tree_view1); gtk_container_add(GTK_CONTAINER(scrolled_window2), tree_view2); gtk_paned_add1(GTK_PANED(paned), scrolled_window1); gtk_paned_add2(GTK_PANED(paned), scrolled_window2); </code></pre> <p>However, now the window collapses itself to the point it is almost a thin trance, as in the screenshot below:</p> <p><img src="https://i.stack.imgur.com/n7mu8.png" alt="Insanely small window"></p> <p>If I maximize the window, the first column does not appear (although I can manually expand it):</p> <p><img src="https://i.stack.imgur.com/VDBjA.png" alt="The first table does not appear"></p> <p>So, what is the best method of getting the appearance of the first screenshot wen using <code>GtkScrolledWindows</code> in this scenario? Also, could I define the size of the pane columns in relation to one another (for example, 30% for the first one, 70% for the second one?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
