Pictures will explain the title:
Under LMDE & Ubuntu 12.04 my GtkIconView looks like this - its correct in terms of the spacing between the icons:
Under Ubuntu 12.10, 13.04 & Fedora 17 the same code displays as follows:
N.B. - This is a rhythmbox python plugin - source code is here on GitHub
I've checked the following GtkIconView attributes - they are exactly the same between Ubuntu 12.04 and in the incorrectly displayed 12.10 version.
- item-padding
- row-spacing
- column-spacing
- item-width
This display behaviour occurs immediately when I set either the text_column or the markup_column (the text under the icons) to be a visible column i.e. changing the value from -1 to the column number.
If the text column/markup column is hidden (i.e. a value of -1) then the display is correct on all distro's.
Since its the same code running on exactly the same music collection - I can only surmise that the newer GTK libraries in Fedora 17/Ubuntu 12.10/13.04 are behaving differently.
My google-fu has only found this reference which sounds identical. However examining the ubuntu-accomplishment-viewer source code hasnt really enlightened me.
Has anybody else encountered this? Any suggestions on the best way to investigate further?
Ok - I've tried to reduce this to the bare ess
