I am annoyed that the sort indicator disappears from my GUI when I present data that requires only 2 columns. The rationale is simple: if we don't do it, it gets confusing. In a GtkTreeView with two columns, of which one is sorted, you basically have a list that is two colors in half. You cannot tell which one is the highlight (of course, unless you know what the real default background color is). This issue got filed multiple times and in the end it was decided to fix it this way. regards, -kris. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Mikael Hallendal wrote: Would it be possible to provide a screenshot that shows the problem you are seeing? It now appears that I fell victim to misleading documentation. The reference manual says that setting the sort indicator to true causes an arrow to appear in the header button indicating the column is sorted. On my system I see no arrow. Instead, the column is shaded. I believe that the manual is wrong when it says that an arrow appears. The second problem is an ambiguity in the manual. The statement describing the effect of setting the sort indicator to true seems to imply that the arrow will not appear if the column is not sorted. This interpretation prompted me to set the sort indicator on all columns with the expectation that the arrow would appear only on the one that was sorted. What actually happens when one sets the sort indicator is that the column is shaded, so setting the sort indicator on all columns results in what looks like a colored background. I suspect that I am supposed to set the sort indicator manually on the appropriate column (and only that column) whenever I switch sort column. -- Jeffrey Barish ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Also note that rules-hint is only a hint to the theme engine; if the theme engine sets the allow-rules style property to FALSE (the default is TRUE) the colors will not be alternating. The application always has the final call about showing alternating colors, if the application sets rules-hint to FALSE and the theme still shows alternating colors, the theme is broken and needs to be fixed. The rules-hint property is always False in the TreeView regardless of which data set I display. If I set rules-hint to True, I do indeed get alternating colors in the background with all data sets. However, the colors are darker for the data sets that had alternating colors already. From your last statement, I conclude that the Ubuntu theme is broken. I gather that the reason I do not get alternating colors in the background of the treeview on the other platform with exactly the same code is that the theme on that platform is not broken. Because the background comes and goes depending on the data I display, it must be that something in the data is provoking the defect in the theme. If I can find out what that is, perhaps I will have a clue how to fix the theme. Stop presses. It's the number of columns. All data sets that require 3 columns have a background.
