I have this small application for viewing select log data from a certain game that I originally wrote in C++/Qt. For various reasons, I decided to rewrite this app in D using gtk-d. First, I have to say that the documentation for gtk-d is atrocious! However, I managed to cobble together enough information to get 80% of it done.

I would like to be able to controll how the cells in a TreeView are rendered (ie the text color used) but I'm not able to find any information about how to do this. Does any one have experience here? If so, can you please give me a clue?

Any information about using gio.Settings would be really appreciated too.

Hi Ivan,

I would recommend you to search for information about Gtk under valadoc pages [1]. You'll get Vala syntax but doing the mental-mapping to D+GtkD is automatic, i.e TreeView [2] and Glib Settings [3].

To change how a cell is rendered you will need to add a CellRenderer to the column, a CellRendererText would be used for rendering text and it has a foreground property to change the text color.

A small example on using CellRenderers can be found here: https://github.com/gtkd-developers/GtkD/blob/master/demos/gtkD/DemoMultiCellRenderer/DemoMultiCellRenderer.d

If the color needs to differ between the different rows you can use TreeViewColumn.addAttribute to map a property of an renderer to a value on the TreeModel.

If the color depends on the value of the cell TreeViewColumn.setCellDataFunc() is also an option.

Thanks. It looks like setCellDataFunc is what I need.

Thanks. I'll give it a look.

Since I wanted people to just be able to run the executable and not have to go through some install process, glib.Settings turned out to be a no-go since it requires a schema file to be installed in a specific place. Instead, I just create a json sidecar file next to the app in order to store settings.

I solved the TreeView text cooler l color issue by using markup.

The application code is in this repository of anyone is interested: https://github.com/Barugon/CotA

Phoned.
