some things in GTK+ 2.7.5

why is the order of allocating paned-child1 and

twice the same lines, lines 2558 and 2560 :

is this correct ?
in GTK+ 2.7.5\gtk\gtkcheckmenuitem.c

offset = GTK_CONTAINER

is the first offset = ... really necessary here ?

configure.in changes
I just rewrote large chunks of the X checks in configure.in ... there were a couple of points of this: - Remove the entanglements with pangoxft, which I've removed as a dependency of GTK+. - Use pkg-config as much as possible rather than older heuristics. With X11R7 .pc files for the X libraries will become a lot more common. - General simplification In general I think what's there now is quite a bit cleaner and simpler, but since I can't test most of the cases, there certainly is some possibility that I broke something. So, if people want to test out what is in CVS now I'd appreciate it, especially for those deviating from the central stream of Linux+recent X.org.

Most probably this means you have a corrupt font. GPOS is a class of tables in OpenType fonts. You can find the guilty font by using the tool in the pango source tree called pango/opentype/ottest to parse the OpenType tables in all fonts you have installed and see which one produces a similar error.

Re: Uninstalling gtk
Hi: I've installed GTK+2.7 on a Madriva 2005, and I didn't remove anything: that way the systems thinks the old GTK+ version is already installed, so there's no problem with dependencies. The new libraries overwrite the old ones, provided that you configure the packages with the --prefix=/usr option. And these libraries are binary compatible, so the applications still work. It worked for me in a transition from GTK+-2.4 to 2.6 in my former Mandrake system, and now with the change GTK-2.6 to 2.7 (however 2.7 is still a testing release, so some times Firefox and Thunderbird crashes) Regards, D.

designing an XML editor TreeView
I need to create an XML editor TreeView for SVG files. Right off I'll ask if anyone knows of a nice example of an XML editor written in GTK+ that I can take a look at. I'd want to be able to drag and drop sections of the markup and edit/add elements, attributes and values. I see the tree view having 6 columns an 'id' (string) for easy lookup of important elements. They usually have an id for a reason. a 'type' (pixmap) iconic a 'image' (pixmap) a dynamic graphic representation of the object a 'tree_control' (pixmap ^ ... ) a 'name' (string) an element or attribute name an optional 'value' (string) for attribute data. The attribute value can be a string, an enum, a number (possibly integer) coordinate data, color data, etc. So the interface for editing attribute values can benefit from some extra interface work to help the user work faster and to provide some built in data validation and hinting. I have code to validate SVG. i.e. If the value is an enumerated type, it would be nice to have a drop down selection control attached to the value that allows the user to select another valid enum. If the value is a paint, there are several options, fill styles, gradients (reference id's or url's) colors (named colors, red/green/salmon, web colors, #FF00FF) etc. One idea that occurs to me is to create right click menus for each property type, but it would be cleaner if I could integrate controls into the value field, like a dropdown box icon for enumerated items. The paint value is a good example of a complicated field that would benefit from several types of UI possibilities: 1) select an id of a valid fill type from a dropdown (i.e a previously defined gradient) 2) select a named colour value from a dropdown 3) enter a web colour directly into the field (#FFF0B6) 4) pull up a colour dialog 5) select from a list of colours used elsewhere in the document. for continuity. A right click menu would be the easiest to implement and would not complicate the tree view, but would lead to the creation of modal dialogs. I'd like to avoid that in favour of creating UI Widgets right in the tree view if possible. If anyone can suggest a clean approach to this can of worms I'd very much like to hear it. Also, this brings up UI design issues that may be unique to GTK. If there are cleaner and faster ways to do this, or just dead wrong approaches to this kind of thing I'd appreciate heads up opinions on those too. :) -- Cheers!
