Commit 3f306a4042 made it possible for
gtk_tree_view_top_row_to_dy() to be called recursively. (In a different
way than was already guarded for). This caused a single test case in
the scrolling test suite to fail. We now also guard for recursive calls at
the beginning of gtk_tree_view_top_row_to_dy().
Rework the sort and filter models to store their reference to the parent
element as an array index instead of a pointer to an array element.
These pointers could become invalid with any array modification, whereas
indices do not.
If we have a level with zero visible nodes and the first node becomes
visible in that level, then parent has just become a "real" parent node.
In such a case we need to emit row-has-child-toggled. This only applies
to non-root levels that have a parent. This problem was also found when
writing the unit test, the respective cases in the unit test have been
corrected.
This fixes bugs:
Bug 372010 - Filtering not working properly
Bug 525965 - Filtered and sorted GtkTreeView is missing rows
When a filter function is used that determines the visibility property
of a node using whether or it it has children, the state of this node
very likely changes when the filter model receives a
row-has-child-toggled signal. Therefore, we need to handle state
changes in the row-has-child-toggled handler.
The license field was introduced later on, so some out-of-tree loaders
may not set it. And Solaris printf() doesn't take NULL for a string...
Bug 594178.
Add a function to obtain the effective context id, and reset the slave
only when the effective context id is different from the current context
id, when setting a client window and on focus in. This might fix
bug 593868 and bug 567124.
